Tobias,
Indeed Buffer 0 won't do any good on self intersections. Thats just not
the way to repair them.
Hence I wrote "Buffer 0 on INVALID geometries IMHO can lead to good
results depending on the /nature of the invalidity/. To my experience

Hi,
I'm mosaicking a large number of small tiles using the GDAL python bindings
(python 3.7, gdal 3.0.1, but also tested on 2.4.2). Code is something like
```
*output_fname = "/something/or/other.vrt"*
*fnames = ["file1.tif", ..., "fileN.tif"]*
*dst_ds = gdal.BuildVRT(output_fnam

Hi all,
I've been experiencing some behavior using the GDAL python bindings where I
am occasionally seeing what appears to be random blocks of the tiff being
unwritten in geotiffs I've pushed to S3. a small block(s) in one of the
bands will be all zeros while everywhere else is good.
My setup is

I've, unsuccessfully, tried to reproduce your issue with the following script:
-
from osgeo import gdal
import concurrent.futures
def worker(in_f, out_f):
gdal.Unlink(out_f)
gdal.Warp(out_f, in_f, options = '-co COMPRESS=DEFLATE -co TILED=YES -ts
2048 2048')
jobs = []

But many users act like this:
1. Get a warning about invalid geometry,
2. run Buffer 0,
3. Warning about invalid geometry is gone.
Again, this is
Hi,
I want to use gdal_contour to generate shapefile contours which is
pretty straight forward except I'm working with coastal relief data that
has both elevation and bathymetry. I only want contours for the bathymetry.
I tried setting the -off -5 and -i -5 with the idea that this would
star
I included as much detail as I could. I put links to all images because I
wasn't sure they would embed in the email list. Experienced programmer but
brand new to gdal.
Overview: My drone is taking multiple high resolution images that slightly
overlap each other in order to view 1 large high resolu
Nick,
That's lots of info and questions. Just from a quick overview, it looks
like you need to set your ground control points to the correct lat/lon
coordinates (or whatever coordinate system you want to use) and you also
need to set your image's projection. You can do both of these with the
Thanks for trying out accessing FlatGeobuf via http.
For the record I've been slightly aware of this particular efficiency
problem and I aim to improve it when I can get to it, because this is a use
case I definitely want FlatGeobuf to grab the first place. :)
