Hi, I have a program that is reading and writing to a GeoTif file using Open, RasterIO and Close calls and Float32 data types.
However, I find that the file just gets larger and larger whenever I write to the file even though I'm trying to overwrite the existing data. For example, if open a Tif file with a large range of values and then write the same value to every pixel and close the dataset, I don't see any reduction in file size as I would expect to result from the compression. I've noticed this with LZW and Packbits compression, tiled and striped. I'm sure it's something simple I'm missing.
