ORTHORECTIFICATION

Orthorectification is the most common way of eliminating the mutilation inside a picture brought about by landscape alleviation and the camera. This is finished by demonstrating the nature and size of mathematical bends in the symbolism. Camera or satellite models related to restricted ground control, permit development of amendment formulae that produce precise, mathematically right, map-situated symbolism. ATOM utilizes Leica Photogrammetric Suite to deliver ortho pictures.

ATOM offers different choices of territory datasets for orthorectification. The decision of DTM utilized for this interaction relies on clients exactness necessities. ATOM offers orthorectification utilizing following landscape sources:

GE-1 DTM
ALOS PRISM DTM
ASTER DTM
SRTM (Cheapest and most coarse choice)
Client gave DTM

Orthorectification is likewise normally required assuming a few pictures or scenes should be mosaicked to guarantee that the joins are consistent. For both correction and orthorectification, precise ground control is fundamental for produce mathematically exact symbolism. ATOM  likewise gives choices of Seamless mosaicking of huge hates for an outwardly engaging picture.
