location Arrays that's exactly what the warper does with geolocation arrays, set the target extent, dimension, and crs with -te, -ts, -t_srs with gdalwarp. python will have those analogous controls for the warper. Cheers, Mike On Sat, 5 Nov 2022, 01:23 Brendan Heberlein via gdal-dev

Hello, I would like to be able to warp an image dataset using a geolocation array, while specifying the grid to which the output dataset is sampled. Specifically, I want to be able to warp the dataset to a grid which is not oriented North-up. Can GDAL support this currently? Or, what is the lik

[gdal-dev] Transformer from & to Control Points in Map CS

2021-06-18 Thread Brendan Heberlein via gdal-dev
Hi all, I wondered if anyone may help me understand how to accomplish this with GDAL (Python API preferred): I would like to create a custom Transformer, based on control points which associate (map_x1, map_y1)​ with (map_x2, map_y2)​. The projection is the same for both sets of points. This

Hello all, I have been using gdalwarp​ to georeference sensor data with geolocation arrays. I have observed that GDAL assigns values to pixels that clearly fall outside the geolocation footprint, producing some funny artifacts at the image edges. For example, see the image here
