DESCRIPTION

       glgrib is an application to display fields encoded in GRIB edition 2 using OpenGL.

       Features : raster, contour, vector, colorbar, mapscale, coastlines, borders. Lat/lon,
       lambert, gaussian grid. GLFW backend for interactive display (glgrib-glfw), EGL backend
       (glgrib-egl) for batch processing without X11 display.

       Tested on :

       VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor
       Integrated Graphics Controller (rev 06)

       VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
