[gdal-dev] Creating Raster using Spatial Coordinates (Latitude and Longitude)

[Chaitanya kumar CH]

Dheeraj,

OGR's CSV driver[1] can read your vector data.
You have to decide how to represent your data in a raster. Interpolate
missing areas, set nodata pixels or something else.

Have a look at the gdal_rasterize utility[2].
