Vectorization / Digitization
The village maps scanned in image format are digitized using heads-up digitisation in CAD environment
using AutoCAD. A standard template is used to have uniformity in layers, line type, colors etc., for digitisation
of the village maps.
The default setting in Auto CAD for all the layers is done. The default settings assume that
scanning/paper coordinates are in centimeters. If the scanning / paper coordinates are in some other units then
the symbols, fonts, etc., are proportionately scaled. The symbols, standard legend and logo block for use in
the digitisation process are created as symbol libraries and are available both as insert able blocks within the
template drawing and also as separate drawings in the "blocks" directory created for the purpose. All
digitisation has been done using standard template designed at MRSAC. All the features have been captured
on the respective layers as per the template. After completion of digitisation, symbols have been inserted as
per their location on village maps. Text is then inserted for Parcel / Khasara nos. using ‘Marathi font'.
