Map-sheet Index of the National System of Mapping
Map-sheet Index of 1:50,000 National Maps
Map-sheet Index of 1:100,000 National Maps
Map-sheet Index of 1:200 000 National Maps
Map-sheet index of basic maps of medium map scales issues from dividing
maps 1:200,000 scale,which is constructed artificially at a map projection
workplane. These maps are of trapezoid form: 38 cm height and approx.proportion
of base-line and height 5:4. Map sheets of this basic scale are indicated
by two-digits sequenced numbering (i.e map-sheet Brno Moravia is identified
by the No.24.) Map-sheets of larger scale are derived from this basic map
by gradual division into four parts. Map-sheet Index of 1:10,000 Basic
Map System is derived from 1:50,000 scale map but dividing scheme is based
on 5 rows and 5 columns.
Example of sequence numbering-indicates map sheets of area Nove
Mesto in Moravia:
