Aerial Triangulation
- Aerial
Triangulation of Aerial Photographs and Satellite Stereo-pairs is done
both using GPS-IMU/RPC files with or without Ground Control Points.
- Both
Automatic and manual AT is performed as desired by different clients.
3D Cartography
- We
have team, experienced in capturing planimetric features at regional to
large scales ranging from 1:5000 to 1:480.
- Number
of features ranges from 30 to as high as 240.
DSM, DTM and Contour Creation
Excel
Geomatics provide
a)
Auto correlated DSM, after hydrographic re-enforcement
b) DTM, representing the ‘Bare Earth’
c) Contours after smoothening
d) Manual Contours (Stream Contours)
Ortho-rectification, Mosaic & Color Balancing
Aerial
images are orthorectified using EO parameters and DTM.
This
is done either using inputs provided by the client or by performing AT and
creating DTM, in-house.
Color
balancing, Seam-line creation, manual seam-line editing, mosaic creation, and
tiling are followed by ‘digital retouch’ to create quality output.
Ortho-rectification, Mosaic & Color Balancing
Excel
Geomatics has got the capability to generate ‘True Ortho photo’ using Digital
Surface Models and multiple images with more 80% of overlap. It is ensured that
after True-Ortho rectification
The
process of True Ortho-rectification is followed by the process of color
balancing and digital retouch to create a seamless and visually pleasing
output.
Mostly Tiling is also performed to ease data handling.
