I removed the layer I did not need, but I still get the same error on the A2 file. The new A2 file is about 1/2 the size of the previous file. The weird thing is that use to work but I regenerated the contour line using the topoprocess instead of GM and I also updated some data.
Here is the cgpsmapper doc:
E024 Top layer detail level too
high to cover entire map -
decrease detail level of the
less detail layer (use higher
Level#).
This error needs a little more explanation since it is
often a source of confusion.
The last layer (the empty one) must always have
one 'tre region'. The maximum size of this region is
65535/2 * resolution (grid). If the map covers a
large area, the selected grid may be too low to
allow the desired 'tre region' to be created.
The maximum size of any object strictly depends
on the bit resolution. For resolution 24, the
maximum size ≈ 1.5 metre * 65535. Similarly, for
resolution 23, the maximum size ≈ 3 meter *
65535. This means that if the object is too big to fit
into the given layer of the map, the bit resolution of
this layer needs to be decreased so the layer can
accept bigger objects.
This is really strange because there are no large objects in A2. There are just few single points.
Currently cgpsmapper is running on A3 but it looks like I have few MP files similar to A2 that are on the edges of the MAP. Maybe I can just ignore the error?
