Hello. I am using GDAL 3 in a c++ project. I have found that GDAL does not
seem to properly read values from raster datasets that it has created. For
example, if I create a new raster dataset with one band and read the min and
max values from that band, it always returns -4294967295.0 and 429496729
What is the proper procedure for resizing a raster GDALDataSet?
I am using GDAL 3 in a c++ project. The software I am interfacing with
expects raster data to always have dimensions that are powers of two. What
is the procedure for resizing a data set while leaving its geo-referencing
information
Using GDAL 3.0 in C++, how do I read pixel values from a raster band?
Essentially, I am looking for something akin to GetValue(int X, intY)
Unfortunately, with the documentation pages down,
https://gdal.org/classGDALRasterBand.html, I haven't been able to make much
headway on this.

Using GDAL 3 and PROJ 6, it seems this is the function I must call to point
proj to the location of the proj.db file it needs. However, any time I call
this function, it results in an access violation.
Does anyone have an example of how to call this?

Thank you for your reply. PROJ version 5.2 builds successfully and never
pestered me for sqlite, so I don't think that would be the problem.

I can't seem to get GDAL to statically link to PROJ when building.
In the nmake.opt file I changed PROJ_INCLUDE to point to my local copy of
the proj source and PROJ_LIBRARY to the exact path of the static lib I built
from Proj source, while uncommenting both lines.
Still, when I try to use ogr c
Thank you so much for the explanation, however, I fear it will not help my
problem.
You see, I cannot build GDAL3 without PROJ4 6.0, and I wouldn't want to
because important functionality would be missing. However, I cannot build
PROJ because it depends on SQLite3. I cannot build SQlite3 because
Thank you for your reply.
Unfortunately, I had never heard of a .yml file before your post and I would
not know what to do with what you have linked. My attempts to research it
haven't yielded anything useful.
Is 100 USD per hour worth anyone's time?

seems to be because I am
not able to build PROJ 6.0. I have spent several days on this now and am at
my wit's end.
If interested, contact me at cdelancy@blackfangtechnologies and name your
price.
