Process_Description:
Using a large format scanner, each map was scanned at 300 dots per inch (dpi) resolution and 24 bit color depth. Each image was then resampled to an 8 bit .jpeg file with an associated color lookup table for features corresponding to the colors present on the original maps.
The maps were then geographically registered into their respective projection. For maps falling within Zone 41, Longitude range 60° - 66°E, the Projection parameters are: Projection: Gauss-Kruger, Datum: Pulkovo 1942, Spheroid: Krasovsky, Scale Factor at Central Meridian: 1.0, Longitude of Central Meridian: 63° 0 0.00, Latitude of Origin of Projection: 0 0 0.00, False Easting: 11500000, False Northing: 0.
Using Erdas Imagine's batch projection utility, the maps were reprojected into Geographic, Decimal Degrees format. The resulting Erdas Imagine files (.img), were then imported into PCI's Geomatica Focus module. Within PCI's Focus module, a shapefile, in the same projection, was used to delineate quadrangle boundaries to clip map collars from the topographic information. The resulting clipped images were then exported as .tif files.
A subset of data was created for UTM Zone 41 by using PCI's Geomatica Focus module. The reprojection utility was used to reproject the images from Geographic, Decimal Degrees format into UTM Zone 41 coordinates. A shapefile, projected in the appropriate UTM Zone, was used to delineate quadrangle boundaries to re-clip NoData values from the edges of the projected raster data. The resulting clipped images were exported as .tif files.
