Dear all,it's more of an application question than a developer's , - AFAIK there's only 'gdal-dev' ? Mea culpa if this doesn't belong here.
To get exact distances between local points, UTM requires a correction factor, depending on local height and distance to the UTM reference meridian. Mainly due to UTM's 6deg steps, - as opposed to the smaller 3deg of GK, where this correction could have been neglected. My current idea is be to transform an area of 10km x 12km to XYZ coordinates that closely match 'field measurable' distances between two points.
(Pls note that this isn't LatLon<->UTM , for which there are heaps of howto websites)
What would be the advised way to handle this in GDAL ? Or a good keyword to find this in the GDAL doc ? "local coordinates" maybe ? Or convert the dataset to the older GK and just use that ?
Any pointers much appreciated, TIA, best, Peter
