Hi all,
Is it possible to have PMapper displaying the map in say Web Mercator and
then measuring distances and areas from a local grid system?
Many thanks

dear all.

the information/identify show no result,
i try with change TYPE with LINE and POINT it works the identify show value
but the POLYGON is no result.

I would suggest you try the query by point on your map file with the
sample script from

adapt the parts at the beginning where indicated.
Then you will see if it returns any results or not. If not ask this
questions better
Hi Armin
I use another webgis system that splits out the map display from the
geometry side - hence the thought, and have some basemaps that prefer web
mercator. Trouble is have a new project that has an initial extent that is
really a bit big for a local grid projection, so just feeling out the
Base maps can be re-projected if needed.
A rectangular projection suitable for larger areas is Lambert Equal Area
(which, as the name suggests, allows acceptable area calculations). An
example is EPSG 3035 that fits for whole Europe without too much of
distortions at the edges. You can define
