Hi Gerd I've come to the same conclusion looking and was quite confused when Frank introduced his dem builder: I too noticed the tdb DEM flag was always set eventhough there was no dem. Nick On 11/01/2018 08:03, Gerd Petermann wrote:
Hi all,
the help says --show-profiles=1 Sets a flag in tdb file which marks set mapset as having contour lines and allows showing profile in MapSource. Default is 0 which means disabled.
I've tried this with MapSource. My findings: The option is not related to contour lines, those are always displayed and height is shown when you select one. I found two effects of show-profiles=1: 1) The button "Show Profile..." in the Route Properties popup is enabled even if no DEM data is available. Without DEM data this button is of no use, the displayed profile is a straight line at height 0. 2) With DEM data available Mapsource displays the height in the status line when you hover over a hill-shaded area with valid data.
The button "Show Profile..." in the Route Properties popup is always enabled when DEM data is available.
My conclusion: The option is useless without DEM data and with DEM data it should default to --show-profiles=1
In other words: I think the option should be removed and the flag should be set depending on the DEM data.
