[mkgmap-dev] Wrong "Object Class" displayed in Mapsource

Fri Apr 5 22:50:42 BST 2013

Hello,

I am creating my own map with mkgmap and am using it on an eTrex Vista 
HCx and with Mapsource.

In Mapsource, when the mouse pointer is moved over an object (like a 
road, a building or another POI) and the right mouse button is pressed, 
a context menu appears listing anything under the pointer.

If there is no other polygon (like forest, residential, ...) than the 
"empty" background under the mouse pointer, Mapsource lists the 
background as "Hospital". Please see
http://www.mipri.de/dl/background.png for an example.
"Kartenmerkmal - Straße" is correct, but "Krankenhaus - Unbekanntes 
Gebiet" ("Hospital - Unknown area") is not.

In my TYP file I am using 0x4b for the background, while my style (like 
the default style) is assigning 0x0b to hospitals. I don't know if there 
is any relation, but some days ago Gerd wrote:

Could it have to do with this?

There are other cases where the labels in Mapsource are wrong:

If I am putting the mouse over a "real" hospital, the building gets 
listed as "Marine", see http://www.mipri.de/dl/hospital.png. In this 
case "Krankenhaus - Chirurgische Klinik" is correct,
"Marine - Chrirurgische Klinik" is not.

Something similar happens with forests, but only if there is no "wood" 
key defined. In this case, they are listed as "Autoservices - Wald" 
("Car repair - Forest") as in http://www.mipri.de/dl/wood.png.

The examples were taken near the University of Ulm, Germany, but it 
could be elsewhere. The mouse pointer did not get captured in my 
screenshots, it was at the position in the upper left corner of the 
popup menu.

These wrong labels seem to appear only in Mapsource, I did not see them 
on my GPS yet.

Any ideas what could be going wrong here?

Thanks,

Michael
