Job Discerption
1.	Accurate scanning of original paper-based maps (generation of raster image of the map).
2.	Digitization of plots (drawing digital line on each plot boundary of the scanned map).
3.	Topology creation and closed polygon generation in area layer.
4.	Creation of plot numbers in polygon area layer.
5.	Creation of rendered plot numbers (RPN) and centroid point of each polygon in point layer. The centroid, which is the geometric centre point of the polygon, is where the plot number is indicated. When the size of the polygon is too small for the number to be written within it, then the last one or two digits are written to represent the original number. This plot number is called rendered plot number.
6.	Creation of in-situ lines, i.e., geographically fixed lines and point alamats (line and point layers).
7.	Thoka lines of mouza (i.e., boundary lines of the other two neighbouring mouzas) and sheet control points (fixed points on earth used while preparing the maps which are also used for future references), tri-junction pillars (pillars fixed at the meeting point of three neighbouring mouzas), permanent features or marks, old control stations used in earlier surveys, roads, railway tracks, rivers or streams, relay lines of acquisition plans (i.e., demarcation lines of the land proposed to be acquired – relevant only in land acquisition cases), etc., in .shp format of line, point and area layers.
8.	Creation of DBF files for point/area alamats and bata (sub-divided) plots (point and area layers).
9.	Creation of GIF files of non-map features (sheet heading, north direction, legends, list of conventional signs, contents of certificate block).
10.	Creation of text files in point layer.
