I’m building a machine learning model to detect various objects on building rooftops and have decided use a combination of AHN and BM5 as input data.
However, since the BM5 images are not true orthophotos, they suffers from significant parallax distortion in comparisom to AHN-based rasters.
It has come to my attention that several organisations have already gone through the trouble of producing true orthoimagery for the Netherlands, and it seems a bit weird that Kadaster hasn’t caught up to them, yet, at least to my best knowledge.
Anyway, I was wondering if is there is a public source for such images or at least a relatively simple method to produce them from BM5 and the AHN DSM? I don’t need to have process the whole country at once; only around 500x500 m tiles, at most, and I don’t care about managing occulted areas because I’ll be masking the output image with BAG polygons.
Thanks.
