    Taking Up Space: The Largest Leaseholders in San Francisco

    by Eric

    Ever wondered what companies are taking up the most space in San Francisco? Kalin Kelly, a director at boutique real estate firm CM Commercial, has been wondering the same thing and decided to take action to find out.

    Over the past few months, she’s been collecting all of the data she can find about leasing transactions in San Francisco. What she’s found is that the biggest real estate deals happening in the city (in terms of space) are mainly being done with technology companies, and that the lion’s share of it is happening along Market Street and into the Mission and Dogpatch. She predicts that the trend will continue south into the Mission.

    Is her prediction correct? Only time will tell. In the meantime, take a look at the map and see for yourself and read more about it in TechCrunch.

    Stamen founder and creative director Eric Rodenbeck has worked with Kalin Kelly as part of his work with the Community Arts Stabilization Trust (CAST).

    Feb 4, 2015 Helping people find parks, and parks find people

    By Dan

    Today we launched for the state’s Parks Forward Commission. is the first statewide parks search engine that brings together expert-level park boundary and management data with social media content from Instagram, Flickr, Twitter, and Foursquare.

    Our mission was to create a statewide search engine for parks that would show you information about parks regardless of agency, so you don’t have to know (or care) who runs the park you want to visit. You just want to know where it is, what you can do there, and how to get there.

    With the definitive California Protected Areas Database (, can tell you exactly which of the state’s 11,826 public parks are near you.

    With activities data from and, will help you find out where you can do your favorite activities, from rock climbing to shooting hoops.

    And you can see what people are doing in those parks from photos contributed by more than half-a-million people, updated from Instagram and Flickr daily. Counts of Tweets and Foursquare check-ins within the parks give a sense of overall popularity and use.

    Tabulating those numbers in recent weeks reaffirmed a core tenet of this project: Parks are social. And diverse Californians will see themselves in parks. We know because we see them on social media. And showing that creates an invitation to share these public spaces. Indeed, the fundamental design principle for this project is that open data and social media can come together to create deeply useful tools to help people get out and enjoy nature together in their daily lives.

    Based on R&D work we’d done to harvest social media posted within every public park in the state (, we were engaged by Resources Legacy Fund and the state of California’s Parks Forward Commission, charged with charting the future of public parks in the nation’s most populous state.

    The products of our previous research work — complex maps of real-time social media that are beautiful in their own right — became the infrastructure upon which we’ve built a simple, powerful tool.

    The first view of the site is a prominent search bar where you can enter a location (anything Google can geocode) or hit the “locate me” button to get a list of parks near you. You can also tap one of the “story blocks” to get nearest-first curated lists we’ve assembled around several different themes.

    From there, you can narrow and tailor your search to see just the activities you’re most interested in.

    At launch, we have activities data and official park URLs for 816 large wilderness parks, plus key city park activity data for 5,447 urban parks across the state. And we have a web application that’s built for mobile. An interface available in English and Spanish (a big shout-out to Latino Outdoors for help on translation and user testing!). All tied into native routing software available on every smartphone.

    But it’s really just a start. There’s a lot more data that could be harvested, and a lot more service to provide to California, and potentially other states and nations!

    We especially hope to expand on the key idea that using social media and open data as a content database both radically opens up the parks conversation and also substantially reduces the risk of launching a new application.

    A radically open conversation means that sometimes we might hear and see things that make us uncomfortable. But with daily image harvesting, the solution is clear: Head out to the park you love and post some images! (Just make sure your location services are enabled.)

    Result: A richer and more engaging view about that park on

    But more importantly: A richer and more engaging representation of that park across diverse social media conversations.

    It might have been safer to build a walled garden: A site where we could control all the content all the time. But securing images for nearly 12,000 parks would be a monumental task.

    And if we’d gone down that road, tending that walled garden would do little for the larger conversation around parks in California. And the more effort that goes into a walled garden, the greater the risk: Walled gardens can be beautiful. They also tend to be short-lived.

    By tapping into the rich social stream created by hundreds of thousands of people living their lives and sharing their experiences, we hope can be a key tool in building the parks conversation and community over the long haul.

    Now, it’s time to get outside. Find and share your next adventure at!

    The Zachary Watson Memorial Education Fund

    by Eric

    Last year, our friend and colleague Zachary Watson tragically died in an accident at the age of 29, leaving many of us shocked and deeply saddened. In his memory and honor, a few current and former Stamens have set up an education fund. It's being administered by our friends and neighbors down the street at Gray Area Foundation for the Arts.

    Zach was a well-loved and much-respected member of our community, involved with and leading some of Stamen's most iconic work. He was a free and independent man, quirky and full of life, pursuing his varied interests with a fresh eye and a big smile. So in that spirit, each year on March 14 (Pi Day) one promising young creative coder will receive a $5,000 grant from Zach's fund to help further their education. The funds will be provided free and clear, and recipients may use the money for whatever they wish.

    You can donate to the fund if you like; we want to keep his memory alive through helping others like him. And if you'd like to apply, or know someone who would, please take a look here for directions.

    I saw a lot of myself in Zach. Among other things, we were both the kinds of young men that thought suits and mohawks went well together. He was a smart and talented and fun guy, and I miss him a lot.

    Donate or apply to the Zachary Watson Memorial Education Fund here.

    Introducing Positron & Dark Matter: New Basemap Styles for CartoDB

    By Beth & Seth

    Ready to make lovely maps using open source data on an open source platform? Two new basemap styles – Positron and Dark Matter – are available from mapping platform CartoDB, waiting for you to make your own beautiful visualizations.

    CartoDB already has a suite of styles to choose from, but some of the ones using OpenStreetMap data were only available at limited zoom levels. With our new styles, visualization possibilities await at all zooms, creating an opportunity for depth beyond what’s been possible before now.

    Throughout both maps we’ve made clear labeling for cities, parks, water bodies, and administrative boundaries. We’ve also worked out the relationships between line thickness and outlines for roads, railroads, rivers, and lakes across all zoom levels. Relative brightness of various features have been tweaked to create an appropriate hierarchy of importance at all zoom levels.

    And finally, we’ve given some extra special love to the CartoDB offices in Madrid and Brooklyn, and the Stamen office in San Francisco (only visible when you zoom all the way in).

    It’s been great working with CartoDB to make it easier for everyone to make data visualizations. Now we’re excited to see what you make with what we made together.

    Want to use these basemaps with Leaflet.js? Here's how:

    var layer = L.tileLayer('http://{s}{z}/{x}/{y}.png',{
      attribution: '© OpenStreetMap contributors, © CartoDB'
    var map ='map', {
        scrollWheelZoom: false,
        center: [40.7127837, -74.0059413],
        zoom: 6

    Let your data story sing!

    Healthcare Variation: Location, Location, Location

    This week, the California Healthcare Foundation (CHCF), a longtime Stamen client, released a completely redesigned and updated version of All Over the Map, a tool to help policymakers, health professionals, and concerned citizens discover variations in the prevalence of elective procedures across California.

    Why does such variation matter? Well, it turns out geography matters when it comes to whether or not a person gets a knee replacement or has a baby through induced labor. And location matters even when the data experts working with CHCF corrected for other factors, like age, race, socioeconomic status, and so on.

    Using this map, one can discover that, if you’re a pregnant woman in Gardenia, you are six times more likely to have an electively induced birth as if you lived in Napa.

    That’s a big difference!

    All Over the Map 2014 is the third version of this interface we’ve designed and built for CHCF, going back to 2011. The key change this year was, well, change. With two data periods available for many procedures, we had the opportunity to highlight not just outliers in one time period, but also how much certain areas have changed over time.

    For example, though Clearlake residents had the state’s highest rate of coronary angiography from 2005 to 2008, that rate dropped by 47% in 2009-12.

    Working closely with CHCF, we were able to create an interface that combines bold colors and simple bar charts with careful and refined interactions and subtle color gradations to bring beauty and subtlety to highly technical data. Color schemes and legends highlight outliers in the data, while thoroughly storing variables in the URL means that all states of the map are easily shareable.

    A Blueprint for Global Water Security: Visualizing Urban Watersheds for The Nature Conservancy

    by Beth and Dan

    Few things are more vital to a city than safe, accessible fresh water. More than 20% of the world’s population lives in areas where access to clean, fresh water is challenging. It’s obvious: Healthy cities need reliable clean water to thrive.

    But how do we achieve that critical goal of safe, secure water supplies for hundreds of cities all over the world?

    The Nature Conservancy, working with the C40 Cities Climate Leadership Group and the International Water Association, has the answer: Conservation strategies could benefit more than 700 million people in the world’s 100 largest cities—one out of 10 people on the planet.

    A rich, new dataset created by Nature Conservancy scientists – and visualized by us – illustrates this opportunity, for more than 500 cities worldwide. In many cases, solutions are very manageable, making cities’ water systems safer and more secure while also benefitting wildlife and ecosystems. The dataset breaks down the water data metrics by quality:

    ..and by quantity:

    It also covers the nature-based solutions cities could use to make their water systems safer and more secure, including best practices for agriculture, riparian restoration, forest protection, reforestation, and forest fuel reduction. These actions help to conserve water while benefitting wildlife and ecosystems in the process.

    TNC brings incredible depth of knowledge to the work, and asked Stamen to help find a way to make their data approachable, engaging and navigable for city managers, mayors, water managers, and residents in cities around the world. The data itself covers 25 different variables for 535 cities, and those cities contain 1,840 “diversions” — watersheds, desalination plants, groundwater withdrawal points — and each of those has nine or 10 data points. If you’re following along at home, that’s 13,375 city data points and 18,000 watershed data points. It’s a lot for experts to manage, not to mention civilians!

    The goal, of course, wasn’t to drown people in all that data, but rather to reveal the most interesting and relevant information at the right time. The team at the Nature Conservancy selected 25 cities to highlight with narratives and images that highlight the story they wanted to tell — that conservation works for people and nature — and our map and page designs showcase that message.

    Once you find yourself on a city page, in Jakarta, for example, you can take in the whole sweep of that city’s water situation with a few simple charts and color-coded ratings. At a glance, you see that much of Jakarta’s water comes from afar, and that its overall water supply is very stressed.

    You might also easily see how neighboring cities – like Oakland and San Francisco, sometimes have very different water supplies and, consequenly, water challenges. In particular, San Francisco’s water quantity is stressed while Oakland’s is not.

    In the end, protecting an upstream watershed from deforestation can improve water quality as much or more than installing an expensive treatment plant. This has significant impact on the bottom line, and New York City’s story is a perfect illustration. In the 90’s the city was tasked to meet state and federal regulations to comply with the federal Safe Drinking Water Act. One option on the table was to create a water treatment plan to the tune of $8-10 billion, not including annual operating and maintenance costs. The option they went with instead was protecting the city’s forested watershed, which cost $1.5 billion and has yielded some of the best drinking water in the world.

    San Diego's approach is a different one: paying farmers to implement conservation measures so the water they save can then be used in the city.

    All in all, TNC estimates that the water utilities surveyed could save nearly a billion dollars a year by investing in watershed conservation. For more on the economic impact of water conservation, download the full report at the bottom of the opening page.

    This map is the culmination of years of work by TNC scientists. We are honored and delighted to have been able to work with them to represent their important work in a clear and accurate way. The Urban Water Blueprint is also designed to explore and share, so that people around the world can understand and talk about the water challenges faced by their cities. Most importantly, like TNC, we hope to see city leaders take action to protect water for people and nature.

    Less doom and gloom, fewer dollars spent! There’s no reason not to conserve.

    The Urbanist: Urban Cartography at SPUR

    It's no secret that the field of cartography has been going through some pretty serious change lately, and that a lot of this change is happening because of work being done here in the Bay Area. San Francisco-based nonprofit think tank SPUR has been tracking developments in the field and doing a lot to get the word out: their current Urban Cartography exhibit is in the pages of Dwell, San Francisco Magazine, and Curbed. We received our copies of the magazine that accompanies the exhibit today. It's great to see the iconic work that Eric Fischer does alongside our own City from the Valley map, Andreas' summer fellowship, and Alan's OpenStreetMap work.

    The exhibit is up through February 2015, so there's plenty of time to pay it a visit.

    Notes from 2. Istanbul Tasarim Bienali – Istanbul's Second Design Biennial

    by Beth

    Greetings from Berlin. Earlier this week I was in Turkey, where I'd spent the last week coordinating the install of our curation, Mapmaker Manifesto.

    The second Istanbul Design Biennial opened to the public on November 1. Produced by iKSV, one of Istanbul's, if not Turkey's, largest arts foundations, the event worked with over 50 artists, designers and artist/designers who each produced a manifesto under the timely theme of The Future is Not What it Used to Be.

    The room for our curation within a curation in is a funny, narrow one, with paneling up to my ribcage topped by nearly 17'x12' of white wall on either side. The other two walls are home to a large window overlooking an abandoned building on one side and the entry way (with another window looking into the room) on the other.

    The room has received an overwhelmingly positive response from curators, mapmakers, designers and artists who have visited it (as well as a mention in Design Boom, featuring The Refugee Project by Ekene Ijeoma and Hyperact.) I had multiple people tell me that it was their favorite room in the entire exhibition, even though the installation was not complete for opening weekend. The manifesto itself was not installed until Sunday evening, and the website (which is the guide to the room) is being added this week.

    Designing inherently comes with a healthy dose of perfectionism, of course the incompletion caused me anxiety and stress. But then I remembered that manifestos (and exhibitions, for that matter) are idealistic in nature and messy in practice. The Mapmaker Manifesto is no exception. The manifesto calls for maps of all kinds as a kind of data collection process, to see if there is any universality that reveals itself through multiple representations of You Are Here. Data will save the world, right? If we can just see the things that are wrong, then we'll fix them, of course. We'll make a future together, if we can just agree on what the map says.

    Of course, we know this isn't true. As Becky Cooper points out in Mapping Manhattan (which was included in the exhibition) maps are by no means objective, and in fact the contrary is true. Not only are maps subjective, they can sometimes be downright wrong. The false location of the Greek School (the Biennial site) in Google Maps reminded many of us foreigners of this fact. Joseph Dana from Monocle took out the pen and paper to route the actual location of another site for one of his colleagues, warning her against using the tool.

    We call out the subjectivity of maps in our curation, which is, in and of itself, a very subjective map of maps. I had the great pleasure of speaking about this during a Designers in Dialogue session with Helen Maria Nugent, moderated by SAIC student and curatorial assistant Denise Bennett. Helen’s project maps the look of love using eye tracking technology, and then manifests them as objects made with the materials of anniversaries, such as paper and silver. Denise paired us together so that we could talk about the expansiveness of mapmaking and types of maps.

    The biennial itself had countless maps hidden inside of it. I did my best to hunt for them all. Here is one about the 6th extinction, by Alexandra Daisy Ginsberg:

    And another one from Repair Society:

    And another one from Occupy Gezi Architecture:

    While I was busy talking about maps and tending to the still-in-construction room, Becky Cooper was on a mission throughout Istanbul. As part of the Mapmaker Manifesto, Becky walked the city with a translator, and documenter, and a whole lot of maps for her Mapping Istanbul project. This project, along with our online curation, will be happening throughout the Biennial, and perhaps beyond it. During her walks, she spoke with over 100 people, and even helped a blind man to map his memories as she described them to her. The hope is to collect enough of these maps and stories to make another book.

    One of the most exciting diversions was seeing the map collection of iKSV’s editorial manager, Kerim Bayer. Over the past 7 years, he has been collecting maps, most of them from 1850–1950. During a break, we rode his motorcycle up to the top of one of Istanbul’s many hills to his office, where he has nearly 1000 maps! Here is a small sampling:

    Kerim is an aspiring mapmaker himself. In speaking with him, it seems there are very few mapmakers in Istanbul (or at least few that he knows). He also pointed out that the OpenStreetMap data in the area is sparse, making it hard to work with. My hope is to keep in touch with him, and perhaps there is an opportunity for a Maptime in Istanbul, with enough people. Design is beginning to take off in Istanbul, and perhaps a community of map designers and data visualizers will come with that shift.

    Things change all the time, of course, but there was an overwhelming sense among many of the artists and designers present that we are at an apex of sorts. Istanbul itself exists in a brackish water between old and new. Perhaps this has always been the case in a city that spans two continents, has had multiple names, and carries with it the weight of thousands of years of history. Taking over an old Greek school with futurist design ideas seemed in and of itself fitting for this year’s Biennial. The future-facing works within the exhibition created a brackish water of its own between art and design, modernism and postmodernism, science fiction and science fact. It can be quite overwhelming.

    Our little room of maps captures this feeling, and like everything else in the exhibition, will before we know it be gone. The documentation, including the maps themselves, will be all that remain.

    Maps -> Istanbul: Announcing Maps and Mappers for the Mapmaker Manifesto Curation

    by Beth

    This year, the Istanbul Design Biennial has chosen the theme The Future is Not What it Used To Be. When they opened the call for participation back in January, they asked for manifestos of any form – words, videos, artworks, anything that spoke to this theme. So the Mapmaker Manifesto was born. This manifesto demands that we look at the data around us in an honest and critical way. With this information, we may choose a direction towards our future and find a healthy, sustainable way to get there.

    It all starts with determining a collective you are here – but what is that? Is it cohesive? Disjointed? Funny? Sad? The works we have selected, put together, begin to paint a picture of the very tip of this iceberg. The content ranges from meditative walks to informal bus systems, with media from paper and paint to vectors and video. It's messy. It's overwhelming. And it's absolutely beautiful.

    Without further ado, Stamen is pleased to announce the artists and works we’ve selected for the Mapmaker Manifesto curation.

    Once we’re done with all of the details necessary to put together the physical space full of the works above, we’ll be working on a digital space as well. Look for more information about this online portion of the curation, coming soon!

    In the meantime, many thanks to these artists for working quickly within a very short turnaround. We are delighted to work with all of you and look forward to showing your maps in Istanbul from Nov. 1 – Dec. 14. Many thanks also to all the artists and designers who sent in their maps. It has been a joy to go through all of them, and a challenge to choose the above list.
