[gdal-dev] How to identify a point is belong to a polygon ?

[Chaitanya kumar CH]

Tai,

The environment variables can be set at the command prompt temporarily
using

SET LD_LIBRARY_PATH=C:\path\to\gdal\libraries
SET GDAL_DATA=C:\path\to\gdal\libraries\data

You can set them in the project settings in VC++. I don't know how.
You can also set them system wide at MyComputer->Settings.
