I have a python script that I need to convert existing geotiffs to poly
KML files. The existing files are multi-colored, and all I want is any
colored area, vs the background color.
If you are interested, we can pay via paypal, send me your hourly rate
and when you are free via e-mail! We
Hi Dennis,
I'd like to take up your offer. This looks like a small enough job. I can
use the gdal_polygonize algorithm to process all the areas with a value
other than nodata value.
Please email me the details and sample data if you would like me to work on
it.

Even,
Sorry, I was thinking of mmap() directly to the file, and having something
like:
CPLVirtualMem CPL_DLL* GDALBandGetVirtualMemAuto( GDALRasterBandH hBand,
int *pnPixelSpace,
GIntBig *pnLineSpace,

I've updated my working branch to match your intent more closely, I hope

the iso enumeration is no longer there, and access to iso geometry
types is via a protected method only.
The reason I asked about GDAL2 is that some of the stuff in OGR seemed

Yes,
Do you see page file activity? If you look at /proc/pid/smaps, you
should be able to see the actual status of the mapping of your data
file. Probably it is consuming a large number of pages of RAM, but
also there should be zero pages written to swap. All clean private or
clean shared, zero anony
