Dear all,<br>
<br>
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.<br>
<br>
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.<br>
<br>
(Pls note that this isn't LatLon<->UTM , for which there are
heaps of howto websites)<br>
<br>
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 ?<br>
<br>
Any pointers much appreciated, TIA, best,<br>
Peter<br>
