Construction in Los Angeles may have exploded during the postwar era, but as a new interactive map shows, the wide age range of its buildings might surprise you. Using open data from local governments,built: LA visualizes the age of roughly 3 million buildings across L.A. County constructed between 1890 and 2008.
Drag your mouse to explore the vast web of communities and neighborhoods, hover over individual properties to discover birth years, and double click to zoom in further. Perhaps best of all, hit the rainbow stopwatch to view a decade-by-decade timelapse of development across the county. The city’s core, in particular, clusters together buildings of century-spanning generations, while suburbs and communities to the east and west tend to represent just one or two decades of development.

Know Your Place
Location: Bristol, England
Website:maps.bristol.gov.uk/knowyourplace/
Know Your Place provides access to a variety of historic maps that cover the administrative area of the City of Bristol. The majority of the maps have been scanned from original archives held at Bristol Record Office (BRO). Because these are scans taken from the original archives you will see damage to the maps in some places including tears and stains and even some areas where people have tried to repair the map. You will also notice variations in the colour of the maps because they have been digitally stitched together from individual sheets. We hope this adds to the historic character of the website and doesn’t detract from your enjoyment in browsing these maps.
The scanned images have been overlain on Modern Ordnance Survey Mastermap digital mapping. In many cases the historic maps do not overlay exactly because of the way in which the original surveys were undertaken It is a tribute to the nineteenth century surveyors that their maps can be fitted with modern mapping at all.
It is also interesting to note the variety in the maps particularly the tithe maps which were surveyed by different surveyors with slightly different mapping conventions, the most extreme of which is the Brislington Tithe Map whichnwas drawn with south towards the top of the map.

Mapping Decline
Location: St. Louis, MO
Website: www.mappingdecline.lib.uiowa.edu
The maps were composed in ArcView 9.2, using a combination of digital census geography, archival maps, and historical and contemporary datasets. The base map for the home and the documents pages is Plate I from N.M Fenneman, Geology and Mineral Resources of the St. Louis Quadrangle (United States Geological Survey, Bulletin 438, 1911).
The base map for the other map series is the ESRI shaded world relief layer, based on the USGS’s National Elevation Data (NED) data.
The White Flight series uses 1940-2000 tract level census data. The 1990 and 2000 data and tracts boundaries were drawn from the Census, the 1970 and 1980 data and boundaries are based on the digitization done by Geolytics for those census years. 1960 and earlier data was adapted from the Donald and Elizabeth Mullen Bogue data, maintained by the Interuniversity Consortium for Political and Social Research. 1960 and earlier tract maps were digitized (working backwards from 1970) by the author.
The historical data and tract boundaries are now much more readily available thanks to the yeoman work of the University of Minnesota’s National Historical Geographic Information System (NHGIS) project and Andrew Beveridge’s Social Explorer.
To display the change over a decade, tract boundaries were normalized for the two census years. This usually meant restricting the scope of the map to the metro tracts of the earlier census, and collapsing data from the latter year into the census geography of the earlier year. In the 1950-1960 map, for example, this required adjusting the 1960 data (323 census tracts) to fit the 1950 geography (247 tracts).
The Race and Property series is based on a number of archival sources. The 1916 layer is based on the text of the ordinance, and on the description provided in “Blocks in Which Negros May Take up Residence,” St. Louis Post Dispatch (2 March 1916) from the clippings collection of the St. Louis Public Library. The scope of the 1923 and 1941 realtor’s zones are summarized in Charles Johnson and Herman Long, People v Property: Race Restrictive Covenants in Housing (Nashville, 1947), and are noted on the City Plan Commission’s 1930 map, “Distribution of the Negro Population,” a copy of which is in the Missouri Historical Society’s map collection.
The NAACP’s 1945 estimate of the reach of restrictive deed covenants is adapted from Johnson and Long, People v. Property, 24, 60. The HOLC security maps were digitized from the 1937 and 1940 St. Louis maps in the City Survey Files of the&Records of the Home Owner’s Loan Corporation, RG 195.3, National Archives.
The Municipal Zoning series is based on archival zoning maps from a wide variety of sources, including the planning and zoning departments of many St. Louis County municipalities. Many (and especially the earliest) zoning plan and maps can be found in the bound and unbound city planning reports conducted by the Harland Bartholomew company and archived in the Harland Bartholomew and Associates Papers at Washington University, St. Louis City ordinances, programmatic reports, and the City’s current property database.

CityPulse
Location: St. Louis, MO
Website: citypulsestl.org
CityPulse is citywide network of beacons that provides pedestrian lighting as interactive art, detects and reports street-level activity in real time, creates civic connections, and offers a new platform for human interactions and entrepreneurship.
Each beacon is a modified standard of an existing lighting product equipped with inexpensive infrared sensors and micro controllers. CityPulse gathers pedestrian motion data for display via the CityPulse Map, which can be viewed on any number of digital devices. Choose to overlay the Map with additional data from other open-API resources.
Because the Map is accessible through any web-capable device, it translates seamlessly into a mobile application or a touch-screen kiosk, making it an invaluable exploration resource for locals and tourists alike. Find a bus stop, see who’s playing at that venue, or just choose a new place to get coffee.
The beacons are available in two sizes: a planted 21-foot-tall Home Beacon and a wall-mounted 10-foot-tall Satellite Beacon. The two different options offer different levels of accessibility, accommodating everything from high-traffic hubs to off-the-beaten-path storefronts.
This variety of beacons creates a complete network of nodes into any neighborhood. Once the beacons are hardwired throughout a neighborhood, they will collect Beacon activation information to send in real-time to the interactive activity Map. When a Beacon is activated, it appears as a “blip” on the Map.
Other blips indicate geo-tagged social media activity. The Map interface can be accessed via any web browser, as well as smartphones and tablets. Due to its intuitive design and quick access to location-based data, the Map offers the ideal interface for a public kiosk (see next page), serving as an informational hub for those unfamiliar with the city, or someone simply looking to explore.
Overlaid with the Map are a variety of helpful options including:
- Venues including restaurants, bars, convenience stores, markets, and other amenities, as well as nearby beacons,
- Promotional sales or current coupons in your surrounding area,
- A calendar of events and showtimes to make correlations between crowds and activities,
- Transit routes and schedules, as well as road traffic reports,
- Applied gaming using CityPulse’s API that encourage exploration (i.e. scavenger hunts, check-ins, etc. and,
Interesting city tips, fun facts, architectural history, community art, etc.

Oakland Crimestopping
Location: Oakland,CA
Website: www.oakland.crimestopping.com
This project is not affiliated with the City of Oakland or the Oakland Police Department, but we do use data published on CrimeWatch, the City’s community crime mapping website.
There are several things to do here:
- Browse crime reports by day and by type.
- Sign up to receive e-mail alerts and RSS feeds for crime reports in your neighborhood.
- Information about site updates and new features can be found on our blog, blog.crimespotting.org.
Unfortunately, CrimeWatch suffers from a few drawbacks that we believe Crimespotting helps to address.
CrimeWatch is inaccessible to many popular browsers, and does not “gracefully degrade” for maximum flexibility. CrimeWatch provides maps of crime reports but makes them difficult to explore.
Our map view is completely explorable - it’s possible to pan and zoom, select date ranges in the past, and view specific kinds of crimes.
You can also share links directly to a particular view of the map, which is important for sharing and publishing information. If you don’t have the required Flash plug-in to view the interactive map, we have a browseable crime database with maps in image form for combinations of dates and types of crime.
We believe that this map-first approach is a valuable and sensible way to publish information for people to use - everyone knows how to find their house, school, or workplace on a map, but few people remember relevant details such as the city council district or police beat these places occupy.
An important source of inspiration for Oakland Crimespotting comes from Chicago Crime, a freely browseable database of crimes reported in Chicago created by Adrian Holovaty and Wilson Miner.
Once per day, we collect fresh crime reports from CrimeWatch and save them in our database. The technical details on how this is done can be found on Mike’s blog, especially in posts from December and January. We are currently exposing crime reports going back one month.
The map is an example of Modest Maps, our Flash and Python framework for displaying tile-based geographical images. The tiles we’ve chosen to use come from Microsoft® Virtual Earth™.

Oakland Crimespotting was designed and built by Stamen Design’s Michal Migurski, Tom Carden, and Eric Rodenbeck. Feedback, complaints, and suggestions are welcome at info@crimespotting.org.

Spatial Information Design Lab
Location: New York, NY
Website: www.spatialinformationdesignlab.org
Spatial Information Design Lab was founded in 2004 as an interdisciplinary research unit in the Graduate School of Architecture, Planning and Preservation at Columbia University.
The Spatial Information Design Lab is a think- and action-tank at Columbia University specializing in the visual display of spatial information about contemporary cities and events. The lab works with data about space -- numeric data combined with narratives and images to design compelling visual presentations about our world today. The projects in the lab focus on linking social data with geography to help researchers and advocates communicate information clearly, responsibly, and provocatively. We work with survey and census data, Global Positioning System information, maps, high- and low-resolution satellite imagery, analytic graphics, photographs and drawings, along with narratives and qualitative interpretations, to produce images.
Spatial Information Design is a name for new ways of working with the vast quantity of statistical and other data available about the contemporary city. By reorganizing tabular data using unique visualization techniques, and locating it geographically, we try to correlate disparate items of information and picture the patterns and networks they create. Putting data on a map can open new spaces for action, and new options for intervention, as the often-unseen shapes and forms of life in the city becomes visible.
Design, here, is less like a tool and more like a language, a practice that shapes the outcomes and understandings of the things we do. It is not simply an aesthetic prejudice. The ways in which we present ideas and information can sometimes be even more important than the material itself, for better, or more commonly, for worse. The words and pictures we choose make a difference to the way people, including us, imagine their own possibilities of responding to what we say and do.
The goal of the Spatial Information Design Lab is to make partnerships with people and organizations inside and outside of the University. We are most interested in research which requires the independence and rigor of an academic setting (free of the usual politics and pressures of real life situations), and which thrive in an atmosphere of open inquiry, experimentation, and risk-taking, in order to expand the ways in which data is collected and used.
