<br>
I have made a python 2.7 / 3.7 program to fuse a point cloud with hyperspectral images. The end result is a text file with xyz... from the cloud file followed by the band pixel values. It’s all multithreaded so a cloud with 6.5 million points can be fused with a raster with 288 band in 45min (12 threads). What would it take to make this an official gdal command line utility? What steps would be involved?<br>
