Hi I am implementing a write driver for the Vertical Mapper/Northwood Grid format (NWT_GRD), which already has read support. I have attached a diff of what I have got so far. Needless to say, it is not complete or working :D.
I'm looking for information on development, specifically: - Precisely what functions need to be implemented so the writing is fully supported? (i.e. the minimum to be able to create a dataset from scratch and write data to it using RasterIO). - Is there any info out there on debugging GDAL drivers? What is the standard approach. Currently im trying to use 'gdal_translate' as a way in to get it to do something so I can set some break points...perhaps writing a little test program would be a better method. Which brings me to - What standards are there for writing unit tests, test programs? I can see a load of python under 'autotest' which im not familiar with. Are there any guidelines on thise (the README is none too helpful). Ive been over the driver implementation tutorial a number of times but info on implementing write support is fairly scant. I'd happily add to this if I can get this done..
