Natural Earth updated to version 1.2

Tuesday, May 25th, 2010

This update introduces supplementary hydrography features in North America and Europe that quadruple (4x) the number of lakes and rivers there. Many thanks to Tom P. for generalizing the vectors and Preston M. for adding tapering to North America (absent in Europe). In some cases the basic 10m rivers and lakes were modified to fit the new information and that’s been refreshed, as well. The North America data comes from the CEC North America Environmental Atlas. The Europe data extract is kindly provided into the public domain by the European Commission, Joint Research Centre (JRC), thanks Alfred J! Check out their original, higher resolution Europe data.

On the cultural front, North America gets roads and rails. General 10m detail roads and railroads come from the CEC North America Environmental Atlas. The supplementary roads are donated by XNR Productions and are at 1m scale, thanks Laura M. and Rob!

If you have data or time to contribute, especially to flesh out the new transportation and hydro themes, please contact me at

Note: We are not committing to building out supplementary level of detail in the rest of the world (we’re not THAT crazy!), but will incorporate such data if you contribute it. As always, we edit these data files but you should too before you publish maps using them. Feed us back corrections.

ISO global road, rail shapefile (Kelso)

Monday, March 30th, 2009

I’m in search of a super generalized but comprehensive global coverage dataset or datasets that shows major highways and rail lines, even sea lanes. You can see an example of this on Plate 21 of the National Geographic 8th Edition Atlas of the World. Do you know of one? Please shoot me a note to or comment here if you have a tip.

Why do I want such? I am working with Tom Patterson (of Natural Earth fame) and Dick Furno (retired from The Washington Post) to release a comprehensive, attributed GIS base map dataset derived in part from the Natural Earth physical wall map at around 1:15,000,000 scale and two other consistent and self referential datasets at approx. scales of 1:50m and 1:110m. These datasets will provide coverage that perfectly registers with the modern satellite remote sensing imagery and SRTM derived topography. Yes there is 1:1m coverage around the world but it is often out of date and too detailed for doing global, continental, and regional mapping.

We hope these open source datasets will allow everyone in the cartographic community to focus on telling the best “why” and “how” visual story about their thematic data instead of spending 50 to 70% of project time looking for or creating the vector geometry that captures the basic “where” of their thematic data.

Release is expected Fall 2009 at the NACIS map conference in Sacramento. Please check back in this space for more details as they develop.

Virginia Road Work Plans Are Halted (Mashup)

va transport road funding cuts

(Editor: I published this mashup for The Washington Post on Thursday, updated Friday. View here. It features custom Wash.-Post-style map markers, KML integration for the linear features, and a table listing out the same cut and delayed projects below the map in text format. The entries in the table are hyperlinked back into the map where a more detailed listing on each entry is found in the info window.)

The Commonwealth Transportation Board voted Thursday to approve a six-year spending plan that cuts hundreds of projects statewide. Below is a sampling of key projects that will be delayed or eliminated. Related article here.
