CollabLand

What is CollabLand? CollabLand is a Software for Digitization of Survey Maps available in the form of FMB (Field Measurement Book). Though CollabLand is mainly used for FMB it can import .shp files (shape files) and can display an individual file. The individual plot can also be divided into parts to cater to the requirements of mutation as prevalent in northern states like MP, Rajasthan, Orissa, UP etc. CollabLand is based on Java and PostGres SQL.

What is FMB? FMB stands for Field Measurement Book. Also known as “Tippan”. In southern States like Kerala, Tamil Nadu, Karnataka, ChattisGarh etc. the land records is maintained through FMBs. In FMB the individual survey number maps are maintained at a scale of 1:1000 or 1:2000. Each survey number is divided into several sub divisions. FMB also depicts the dimentions of each field’s boundaries and sub divisions.

FMB Components G-line F-Line Subdivision lines Ladder This is a imaginary line which converts the map into various sizes of triangles in order to accurately fix the boundary lines and various points in the map. This is the base line and the entire map is based upon it. F-Line It is the outer boundary line in a sketch, which signifies the actual field boundaries of the outer lines of the sketch. The F-line points are fixed with reference to its offset distance from G-line. Subdivision lines These lines demarcate a small parcel of land within a survey number. A subdivision polygon’s extent is directly correlated to the extent found for the particular sub division. The sub division lines are generally defined through a ladder. Ladder The field lines points are defined with reference to an offset distance from the G-line. The offset distance may be to the left or right side of the G-line. This left or right angle deviation, offset is depicted by ladder. By converting the ladder details into electronic data, one can produce the FMB sketch. Neighboring field survey numbers As mentioned earlier, each survey sketch is surrounded by other fields. These surrounding field numbers are marked around each FMB. This enables mosaicing of the FMB’s into D-sketched and village maps so on.
