[mkgmap-dev] Feedback r991 map on etrex legend HCx

Wed Apr 8 06:47:50 BST 2009

I created a new map with r991 and wanted to give some feedback:

I used the zipped osm data from geofabrik.de for thuringia.

java -Xmx1500M -jar splitter.jar --mapid=41000001 --maxnodes=1000000  
thueringen.osm.bz2

java -Xmx1512M -jar mkgmap.jar --tdbfile --family-id=41  
--family-name=OSM_Thueringen
--series-name=OSM_Thueringen --description=OSM_routable_map  
--overview-mapname=41000000 --route --gmapsupp --latin1
--net 410000*.osm.gz

Splitter produced only one tile with the maxnodes=1000000 setting.  
Generation was fine, no errors whatsoever.
The map worked fine on both mapsource and my eTrex Legend HCx.

Some things I noticed while testing on the etrex:

- The address search field appears in the menu. Of course it doesn't  
find anything by now, but at least the menu is present already.

- The road-crossings search field works, but the city name input field  
behaves slightly erratic. It displays a list of road names  
(alphabetically sorted) to choose from. But when I enter a letter, the  
list disappears. I have to type the full name of a city, which will  
make the (full) list reappear with the specific city selected. (Same  
behavior in the citys field of the address search menu)

- Roundabouts give routing informations in the wrong direction. Maybe  
this can be fixed be adding country informations to the mkgmap  
options. I thought this was implemented by looking in the is_in tag now.

- There are no road name pois to search for. I thought generation is  
default by now and the --add-road-name-pois is no longer needed?

- The motorway exit menu works fine. Not tried searching though.

- A lot of POIs are named e.g. UnnamedParking or UnnamedATM (These are  
translations from my german names). I don't know where the 'Unnamed'  
string comes from, but it would surely be better to ignore missing  
tags instead of printing 'unnamed'.

- Some search menues contain a 'find by name' context menu, some  
don't. (Only the 'find nearest ...'). As the 'find nearest ...' menu  
is limited to a fixed number of entries it's not possible to search  
for pois far away. As a workaround I could of course use the unlimited  
'find by name' in the 'all pois' menu. Can anybody confirm that those  
menues appear/don't appear with other (commercial) maps?

- General routing works fine. Recalculation is fine for me, at least  
for going by car.

As always: Thanks for the awesome work !
