This data set consists of a 1:15 million scale forest cover map for the land area of the Former Soviet Union (FSU). Twenty-two land cover classes are distinguished, twenty of which are forest cover classes. The source data were created by map digitization from the Atlas of Forests of the USSR (Anon. 1973), which was likely based on forestry data from the 1940s, 1950s, and 1960s.
The data are provided in several formats, including binary raster data in Idrisi format, ASCIIGRID raster data in ASCII format (easily imported into ArcInfo), and a graphic map in JPEG format (see Figure 1). Please read all documentation before using these files.

fmap73.img
The file is an Idrisi v. 2 image file, a binary raster image depicting forest cover (1973). Note: must be converted to an *rst file when using v. 3.2 of Idrisi. Use the Idrisi File Conversion (16/32) utility available in the file pulldown menu to convert to the new format. Also note that the Idrisi v. 2 image documentation file, fmap73.doc, MUST be present for the binary data to be read by Idrisi.
Not applicable
fmap73.dat
The file is an ASCIIGRID version of the binary raster data (fmap73.img). This data file was created by converting the Idrisi binary file (fmap73.img) using Idrisi export utilities. Note: it was necessary to first convert the *.img file to a *rst file and the *doc file to an *rdc file to match the new file format and naming convention of raster data supported by Idrisi v. 3.2.

The source data for the raster version of the 1973 Forests of the USSR (being distributed here) were acquired by map digitization from the Atlas of Forests of the USSR (1973). These data were projected from conic equidistant projection to geographic using PC ArcInfo using the PROJECT command.
