Capture scale shall not fall outside the range of 1:1000 to 1:5000

Cassini Projection are being followed. On Cassini Projection the North-South stretching of scale is not balanced by any East - West change of scale except for very small areas.

Datum shall be Everest Spheroid. Units shall be Square meters.

Source shall be Digital Ortho-imagery (in ideal cases), that has a verified minimum horizontal accuracy of 10 meters or better, and a minimal pixel resolution of 1 meter.

Edge Matching and Mosaicing


Edge Matching Technique With the Affine transformation ,using four points on each

map cadastral map are pre-matched with road maps.

Sequential Auto-matching: There can be lot of boundary mismatches following the Affine transformation, so an alogirthm is followed for sequential auto matching.

Boundary Line based Automated Adjustment: This algorithm is developed for adjusting cadastral lines based on given boundary lines, the method has three parts: Searching the conflicted cadastral lines based on given

boundary lines; Moving the conflicted cadastral lines to given boundary lines; Related cadastral line adjustment.

Thematic Mapping


Attributes of Land Records

Record of Rights: It contains the ownership details of each parcel, sub-divisions etc.

Crop details: These are updated thrice/twice in the States based on crop seasons and inspection reports giving details of crops sown, area, cultivators and yield details.

Pedigree table – This is pedigree sheet giving the details of family history, relationships with ownership details

Creation of New Cadastral Map

The process of creating a cadastral system can be considered in two parts;

the legal or quasi-Iegal and

administration area which is responsible for adjudication of boundaries and rights in land and the creation of an efficient recording system for those rights in appropriate registers; and the technical area which includes cadastral surveying and mapping.


Approach for Cadastral Mapping There are two basic approaches which may be adopted for

cadastral surveying and mapping; ground survey techniques combination of photogrammetric/Remote sensing and ground survey

techniques.

Ground survey techniques are the basis of most cadastral survey systems. since photogrammetry has only been used for cadastral purposes in the last 30 years or so.

Ground survey techniques suit the sporadic isolated survey approach which is usually a component of land registration. conveyancing or alienation systems based mainly on the "user pays" principle. Such systems are usually the quickest to introduce, and the cheapest and the most expedient for Governments in the short-term.
