I am working on numerical modelling over a wide region between 20-50
Eastern longitudes and 30-50 Northern latitudes. I have lat-lon
gridded bouguer anomaly and topographical data to use for my studies.
Since I need to discretize the area into equal rectangles, I need to
convert the data into metric system.
Is it possible to minimize the distortions when reprojecting? I
converted the grid data to utm zone 34, It gave fake coordinates out
of the zone. Both data fits on each other well on gis softwares. I am
curious if I missed something here. After that I will resample it as
1km gridded surface.
Another question is, I am flattening the surface which is originally
curved. This is another distortion for me because modelling program
will read it as a pure flat surface. Also the rectangles I created
will not be perfect rectangles in reality. How can I quantify the error?
thanks in advance.
