600 Satellite Images to Explore and Share

The website http://www.satellite-images.org presents some amazing satellite images of the Earth taken from the SPOT5 satellite.


It has been developed using Drupal, a very powerful, flexible and Open-Source CMS (Content Management System) and contributed modules. More than 600 images are provided at 1000 x 1000 pixels resolution and are dynamically resized thanks to the ImageCache module. The Taxonomy module enables a interactive exploration through categories, tags and countries links. The FiveStar module enables users to vote for their favorite image in order to promote it to the front page. And finaly the SexyBookmarks module enables sharing of the images with friends over a selection of social networks.

AOL and Bing going Open-Source ?

I found quite interesting that the two main keynote speakers at the coming Navigation Strategies USA Conference in San Jose are Steve Coast, Principal Architect at Bing Mobile and Randy Meech, Head of Engineering, Local & Mapping, AOL.

Steve Coast is the founder of OpenStreetMap and CloudMade. He has recently left CloudMade to join Microsoft Bing Mobile and made Bing Aerial Imagery available to OSM mappers.

Randy Meech has been talking at the last OpenStreetMap Conference in Girona, Spain. He announced that MapQuest was testing OSM in its new portals across Europe and that AOL will spend the equivalent of 1 million $ to enhance the OSM mapping and routing of the USA.

A clear indication that OpenSource mapping is not only for geeks and open-source activists but is really breaking its way into the industry ! It is obvious that Open-Source is not woven into the fabrik of AOL and Microsoft. So it will be interesting to see what is coming up and how Open-Source (or rather Open-Data) and the commercial web industry can find mutually beneficial agreements.

Ivory Coast Mapping : New Satellite Imagery

Since several weeks, the Humanitarian OpenStreetMap Team has been focusing on enhancing the map of Ivory Coast in fear that the situation might get worse with the current political tension in the country. In particular, the map of Abidjan has been greatly improved in the past weeks. Most of the tracing has been done with Bing aerial imagery since Microsoft recently made it available for OSM tracing, but the problem is that it does not cover the whole area of Abidjan.

To answer this need of data sources other than Bing imagery, Astrium-GEO has also offered SPOT satellite imagery over the region of Abidjan to OpenStreetMap. The accuracy is 5 meters, and a little ground mist is visible. However, linear features like roads can be easily identified. This will be especially useful to map out the North and West of Abidjan.

The source tag to use is "2005 Cnes / Spot Image", and this imagery is allowed in JOSM and Merkaartor but not Potlatch. The license agreement is here : http://www.youmapps.org/licenses/EULA-OSM-en.html
