First Look at Natural Earth Vector

Friday, June 12th, 2009

Tom Patterson and I collaborated on the precursor to his first Natural Earth Raster project several years ago and we now preview Natural Earth Raster + Vector, a new free product due Fall 2009 that complements and expands on the previous work by providing detailed GIS linework at the 1:15,000,000 (1:15 million) scale and new versions of the raster product (including cross-blended hyspometric tints). The Washington Post, where I work, is contributing 2 more vector GIS base maps at the 1:50m and 1:110m scales and new versions of Natural Earth Raster will be released for those scales. This is a NACIS and mapgiving co-branded product with assistance from the University of Wisconson-Madison cartography lab, Florida State University, and others.

Please attend the October NACIS 2009 map conference in Sacramento, California for the unveiling.

Map Symbols: Landforms & Terrain (Krygier)

Reprinted from John Krygier’s April 3, 2008 post on his DIY blog.

Erwin Raisz is among the most creative cartographers of the 20th century, known in particular for his maps of landforms.In 1931 Raisz outlined and illustrated the methods behind his landform maps, in an article in the Geographical Review (Vol. 21, No. 2, April 1931). Excerpts from the text and graphics in the article are included below.

Raisz’s approach is to create complex pictorial map symbols for specific landform types. Each specific application, of course, would have to modify the symbols to fit the configuration of particular landforms.

One of the limitations of Raisz’s work is that it is so personal and idiosyncratic that it virtually defies automation or application in the realm of computer mapping. Thus digital cartography has, in some cases, limited the kind of maps we can produce.

Raisz writes:

There is one problem in cartography which has not yet been solved: the depiction of the scenery of large areas on small-scale maps. 

Raisz continues:

For the study of settlement, land utilization, or any other aspect of man’s occupation of the earth it is more important to have information about the ruggedness, trend, and character of mountains, ridges, plains, plateaus, canyons, and so on-in a word, the physiography of the region.
