11 How to read *.res file format on PC
The Optimap3 can create altitude, slope, and curvature map. See above to know how
to activate such saving option.
To get files exported on SD card, user must perform a full export to the SD card. Then,
user will find altitude (alt.res), slopeX (slox.res), slopeY (sloy.res), curvatureX
(curx.res), curvatureY (cury.res). The best way to view these maps is using Rhopoint
Optimap Reader software.
The *.res file format contains first a header made of 256 bytes (from byte index 0 to
byte index 255). To know more about header format user can contact his distributor.
Then starting at byte index 256 are the data written “in line”. Data are recorder in
double precision 64bits.
Using any kind of 3D mapping software such as Mountains, MATLAB, Voxler, Surfer
or others, user can easily create 3D rendering of the surface topography. If the user
experiences some difficulties to read the *.res file, we recommend contacting the
distributor.
