For rasterizing a vector layer, I have tried gdal.RasterizeLayer method for converting vector(shapefile) to raster(tiff). But its giving raster output with NAN values(complete black image). I need some help in which where I am doing wrong. And I want to print one attribute value from shapefile to raster & remaining values should be zero in outRaster.
My code ( using Gdal )is
NoDataVal = -9999 # Open the data source and read in the extent inPolygonShp = r"E:\polygons.shp" outputRaster=r"E:\OutRaster.tif" inGridSize=float(2)/110575 # nearly I am converting to 2 meters gridsize since its in GCS coordinates (vector layer) shpDS = ogr.Open(inPolygonShp) shpLayer = shpDS.GetLayer() # Create the destination data source xMin, xMax, yMin, yMax = shpLayer.GetExtent() xRes = int((xMax - xMin) / inGridSize) yRes = int((yMax - yMin) / inGridSize) rasterDS = gdal.GetDriverByName('GTiff').Create(outputRaster, xRes, yRes, 1, gdal.GDT_Byte) # Define spatial reference rasterDS.SetProjection(shpLayer.GetSpatialRef().ExportToWkt()) rasterDS.SetGeoTransform((xMin, inGridSize, 0, yMax, 0, -inGridSize)) rBand = rasterDS.GetRasterBand(1) rBand.SetNoDataValue(NoDataVal) rBand.Fill(NoDataVal) # Rasterize err = gdal.RasterizeLayer(rasterDS, , shpLayer, burn_values=, options = ["ALL_TOUCHED=TRUE"]) # for rasterizing with a attribute value of polygon # err = gdal.RasterizeLayer(rasterDS, , shpLayer, burn_values=, options = ["ATTRIBUTE= Height"])
Here I feel its generating a raster file but its failed to overwrite with shapefile values. I need some help in this regard.
