GIS Absolutely free Sources - Globe Vector and Gazetteer Information

GIS (Geographic Info Systems) enable information to be introduced visually so as to support Assessment, interpret, manage and Screen facts. A GIS procedure integrates info with hardware and software and can be built-in into a lot of technique frameworks.

In the line of GIS sources, you will discover resources available on the planet Vector and Gazette facts sector plus the Globe Electronic Elevation Versions and Bathymetry sector. This article will deal with the globe Vector and Gazetter Knowledge sources accessible at no cost.

GeoNames is a databases of eight million geographical names with longitude and latitude coordinates, offered below a creative commons attribution license.

GIS Entire world Vector and Gazette Free of charge Useful resource two Vector Map (VMap)

Vector Map (VMAP), is actually a vector-based selection of GIS facts masking the globe at a variety of depth ranges.

Amount 0 (VMap0) has world wide protection, and it is entirely in the general public area. VMap0 is at a scale of 1:one million. It can be a slightly much more detailed reiteration of your Electronic Chart of the entire world (DCW) which was produced in the eighty's and early 90's, which is as a result dated. Nonetheless depending on your uses, VMap0 should still give legitimate geometry for attributes that don't modify significantly (for instance coastline and drainage) and offers a superior start line for areas of the earth in which vector data is difficult to come by.

Stage one (VMap1) is at a scale of 1:250k, and about 1 / 4 of the entire world's coverage is in the general public domain.
