| Additional base map data
(shapefiles) for
all countries in the world can be downloaded for free from
ArcData Online is ESRI's Internet Mapping and Data Site. The site contains a wide assortment
of geographic information that users can access to create map images and download
data.

More, comparable, country
boundary data
is available here
(the International Taxonomic Database Working Group's world geographical scheme
for recording plant distributions).

If you do not care about political boundaries,
and want eco-regions instead, you can download the global
ecoregions map (large shapefile) from the World Wildlife Fund.
|
| Satellite images (LANDSAT false color) for
nearly the world can be downloaded here.
They are in the MrSid format that can be visualized in DIVA-GIS (note: they are
in UTM projections, so you will need to project your shapefiles as well).

| Another very good source global environmental
data shapefiles and grids is UNEP Geo
