I am trying to visualize MGRSGraticule on current branch master which is a few commits ahead of tag 2.10.2.
After executing the line:
osgearth_graticule --mgrs tests/boston.earth
I got the error [osgEarth]* [MGRSGraticule] SQID data file not opened
What is it about? What is SQID file?
@update - when i go to osgearth/tests and execute osgearth_graticule --mgrs graticules.earth i do not get the squid error, but i can see only labels and a bunch of [osgEarth]* [Geometry] Crop failed - GEOS not available errors
It implies your data search path does not include this file. You can usually set this up with OSG_FILE_PATH environment. I believe the SQID file contains data on the locations of the MGRS square subdivisions.
Executing it where you did might work due to relative path resolution. Not sure.
I believe GEOS is a required dependency for some features, this might be one of them.
