The Digital Chart of the World is a set of comprehensive 1: 1 million scale vector data bases. The data cover the whole world. There are over 800 MB of data, which come on two CD-ROMs. The data include coastlines, international boundaries, contours, major road and rail networks, major drainage systems and major utility networks (cross-country pipelines and communication lines). We also provide you with a tool that allows you to tame this enormous amount of data. The included CropDataBase program allows you to extract just the data you need so that Geocart will work with maximum speed. $2,000 (Non profit organizations please call for discount information.) Example maps created with Digital Chart of the World $750
A set of 5 distinct data bases that cover the U.S.
This file is a high resolution coastline data base. Its nominal scale is 1:2,000,000 (about 5 times the resolution of the data base that is included with Geocart). The file is 22 MB and comes on a CD-ROM disk. $300
The Altitude Color data base is a color map of the Earth with the land and water shading based upon the altitude. On land, the lower altitudes are light green moving to dark green, brown and then white at higher altitudes. Deep water is shaded dark blue and shallow water is shaded a medium blue. The resolution of this file is 12 pixels per degree. The file size is 26.7 MB and it comes on a CD-ROM disk. An 8 pixels per degree data base and an image cropping program are also included. $250
The Color Relief data base is a color map of the Earth with highlights and shadows on the land and ocean floor. The resolution of this file is 12 pixels per degree. The file size is 26.7 MB and it comes on a CD-ROM disk. An 8 pixels per degree data base and an image cropping program are also included. $250
The Political World data base is a color map of the Earth with each country colored separately. The resolution of this file is 12 pixels per degree. The file size is 26.7 MB and it comes on a CD-ROM disk. An 8 pixels per degree data base and an image cropping program are also included. $250
The Gray Scale data bases store 3 separate gray scale images in each of the 3 color channels. Channel 1 contains a Gray Scale image in which the Earth's topography is represented by different shades of gray. The higher the area the lighter the color. Channel 2 contains a shaded relief image of the Earth's land and ocean depths. This image can be used to add shaded topography to your maps. Channel 3 contains a mask for separating water from land. The resolution of this file is 12 pixels per degree. The file size is 26.7 MB and it comes on an CD-ROM disk. An 8 pixels per degree data base and an image cropping program are also included. $250
This is the data base to use if you want to create your own color maps. Similar to the Gray Scale data bases, this database has improved accuracy. Use it to create stunning color relief images of the earth's land and ocean depths. Included with this data base are example maps and a detailed discussion of how to produce your own color images. Channel 1 represents the earth's land with different shades of gray. The higher the area the lighter the color. Channel 2 contains the ocean floor. Channel 3 contains a mask for separating water from land. The resolution of this file is 12 pixels per degree. The file size is 26.7 MB and it comes on an CD-ROM disk. An 8 pixels per degree data base and an image cropping program are also included. Examples of using TerrainBase produce stunning color relief images $250
The Gray Scale USA data bases store 3 separate gray scale images in each of the 3 color channels. Channel 1 contains a Gray Scale image in which the U.S. topography is represented by different shades of gray. The higher the area the lighter the color. Channel 2 contains a shaded relief image of the U.S. This image can be used to add shaded topography to your maps. Channel 3 contains a mask for separating water from land. The resolution of this file is 120 pixels per degree. The image extends from 126°W to 66°W and from 50°N to 24°N. The file size is 64 MB and it comes on an CD-ROM disk. An image cropping program is also included. $280
The Living Earth data base is an enhanced satellite photomosaic of the Earth. The resolution of this file is 12 pixels per degree. The file size is 26.7 MB and it comes on an CD-ROM disk. An 8 pixels per degree data base and an image cropping program are also included. Use of this file is limited to non-commercial purposes only. Separate permission must be purchased for each commercial usage. For information on commercial usage please contact Mapthematics. $250
