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

[gdal-dev] Creating Raster using Spatial Coordinates (Latitude and Longitude)
Hi, I am trying to create a Raster using grid of points(with latitude and longitude values) within an area which are separated at a distance measured in degrees. At higher latitudes the number of samples reduce that is number of points for a row reduces. When distance between points is determined with a fixed degree, how do I create a raster where the number of columns for higher latitudes reduces ? In this case, points for grid at higher latitudes are not exactly above the points at lower latitudes. Can some one suggest a way to create raster for spatial coordinates in this case?
