OSM for Beginners: Instructional Videos
I’m increasingly interested in getting more people to contribute to OpenStreetMap, so I will happily note David Ellam’s instructional videos, which are screencasts that show you, step-by-step, how to use Potlatch to add points of interest, roads and areas. Via…
Mapmaking, Map Mashups and Activism
Nancy Scola on Tech President: “Every time something happens in the world these days, somebody makes a map about it. […] But the growth of the digital mapping space makes it worth considering things from the perspective of the people…
A Google Map Maker Roundup
Google announced today that Map Maker is now available for the United States; the tool that allows users to add contributions to Google Maps had, I thought, been targeted at countries where Google lacked map data, but it appears that…
The NYT on Crowdsourced Humanitarian Mapping
A New York Times article about a report discussing the lessons learned from crowdsourced humanitarian mapping, of the sort seen during the Haitian earthquake. Via @geospatialnews….
Both OSM Books Reviewed
If you’ve been paying attention, you’ll know that there are two OpenStreetMap manuals out there — the one by Frederik Ramm, Jochen Topf and Steve Chilton, the other by Jonathan Bennett — each of which, confusingly, is titled OpenStreetMap. Muki…
Still Another OpenStreetMap Book Review
While I continue to procrastinate my own review of the book, here’s another review, by Dan Karran, of OpenStreetMap: Using and Enhancing the Free Map of the World by Frederik Ramm, Jochen Topf and Steve Chilton. Dan calls it…
Grassroots Mapping
GOOD has a piece on Grassroots Mapping, an initiative that started by using balloons and kites to get aerial imagery of the Gulf oil spill in areas that were otherwise off-limits and that has since evolved into the Public Laboratory…
Another OpenStreetMap Book Review
Oliver O’Brien reviews OpenStreetMap: Using and Enhancing the Free Map of the World by Frederik Ramm, Jochen Topf and Steve Chilton. “The book succeeds in simultaneously being OpenStreetMap for Dummies, OpenStreetMap: The Missing Manual and the O’Reilly OpenStreetMap book…
The State of OpenStreetMap in Canada
The news earlier this month that MapQuest had added Canada (among other countries) to its suite of Open MapQuest sites — was something I’d been dreading for some time. I’ve been making contributions to OpenStreetMap’s Canadian maps for a year,…
NYPL Map Rectifier
PSFK has a piece on the New York Public Library’s Map Rectifier, ” a tool for digitally aligning (‘rectifying’) historical maps from the NYPL’s collections to match today’s precise maps.” There’s a how-to video….
OpenStreetMap Manual Reviewed
Another review of the English edition of the OpenStreetMap manual by Frederik Ramm, Jochen Topf and Steve Chilton — OpenStreetMap: Using and Enhancing the Free Map of the World — by Directions Magazine’s Adena Schutzberg. Previously: Two Book Reviews….
Speaking of OpenStreetMap
Last month, it was announced that OpenStreetMap would be getting its hands on Microsoft’s aerial imagery. (One way to make maps in OSM is to draw on top of aerial imagery. Yahoo’s imagery has been made available for that purpose,…
The WSJ on OpenStreetMap, Bing, and MapQuest
The Wall Street Journal takes a look at why OpenStreetMap has been getting attention (and resources) from two large, and very commercial, mapping providers: Bing (Microsoft) and MapQuest (AOL). “For Microsoft and AOL’s MapQuest unit, OpenStreetMap presents an opportunity to…
Bennett’s OpenStreetMap Book Reviewed
On GIS Lounge, Caitlin has a review of Jonathan Bennett’s OpenStreetMap: Be Your Own Cartographer, which she calls “an excellent reference volume for anyone wanting to become involved with this wiki-style geographic data collection project.” Previously: Another OpenStreetMap Book….
The Evolution of European OpenStreetMap Coverage
I’m hard on OpenStreetMap sometimes, but that’s mainly in the context of the North American coverage not living up to the rather Eurocentric hype. Because Europe is definitely where it’s at with OSM, as this video chronicling the growth…
Kite Aerial Photography in Google Earth
You may recall that our friend Frank Taylor of Google Earth Blog has been sailing around the world. Recently he made headlines because his kite aerial photography of Manihi atoll in French Polynesia, taken last May, has been added to…
A Critique of OpenStreetMap
Justin O’Bierne’s critiques of OpenStreetMap’s base map of North America — essentially, the first thing first-time visitors to OSM would encounter: the Mapnik layer — has apparently been stirring up a bit of controversy in the OSM community. Part one…
Potlatch 2
If you’ve been messing around with OpenStreetMap, like I have, you’re probably familiar with Potlatch, its web-based map editor. There’s now a new version, called Potlatch 2, that’s currently under development. If you’re brave enough, you can play with the…
MapQuest Adds OSM for Four Countries
MapQuest Open — the variant of MapQuest launched in July that uses OpenStreetMap data — has expanded to four more countries: France, Germany, Italy and Spain. I hope that reflects a certain level of quality of the OSM maps in…
Another OpenStreetMap Book
Oh look: another forthcoming book about OpenStreetMap. Like the other one, it’s also called OpenStreetMap, which won’t be confusing at all, but the subtitle this time is Be Your Own Cartographer. It’s by Jonathan Bennett and it’s apparently scheduled…
OpenStreetMap Book Now Available in English
OpenGeoData reports that Frederik Ramm, Jochen Topf and Steve Chilton’s OpenStreetMap: Using and Enhancing the Free Map of the World, a book that was first published in German (of course) in 2008 and has since gone through three (German)…
Open Maps of Georgia
Here’s GlobalPost on efforts by a U.S.-funded non-governmental organization, Open Maps Caucasus, to map the country of Georgia — one of the emptier spaces on online maps. Their maps use the same mapping engine as OpenStreetMap, but OSM’s maps of…
MapQuest Embraces OpenStreetMap
In an interesting development, MapQuest has launched a site that combines OpenStreetMap mapping data with its user interface and routing directions. MapQuest Open is limited to the U.K. for the time being (a wise decision considering the state of OSM…
The L.A. Times on Volunteer Mapping
Another article about OpenStreetMap, this time in the Los Angeles Times, which counterpoints it with Google’s crowdsourcing efforts (via OpenGeoData). Articles like these make the point — correctly, I think — that engaged local users can produce a map that…
Ars Technica on OpenStreetMap
OpenStreetMap gets a writeup on Ars Technica that serves as a pretty good summary for the project. Via OpenGeoData. Previously: Washington Post on OpenStreetMap….
OpenOrienteeringMap
Oliver has produced OpenOrienteeringMap, an orienteering map based on OpenStreetMap data, in two formats: The Street-O map contains the level of detail equivalent to the Street-O maps used for informal orienteering races around the streets of London and other urban…
