[mkgmap-dev] mkgmap-dev Digest, Vol 143, Issue 54

Hi Pierre,

please don't attach more screenshots, they are the reason that mails are not forwarded immediately.
The easiest way to set the mapid is the option in splitter. As long as you use only your own maps and those from Garmin you can use any id.
Did you check how many tiles are contained in the open-topo map for France? Maybe John is right and the number is the limit.
If you don't need a full map of France for your journey maybe use a polygon for splitter to cut the area you need.

Gerd

Hi Gerd,

I've removed all my maps except the gmapbmap.img and gmaptz.img which were provided with the GPS itself.

The result is better: some tiles are still missing when displaying the map at high scale BUT when I zoom in on those tiles, the map appears. Here are 2 screenshots.

High scale:
[327.bmp]

Zoom in on the missing area:
[338.bmp]

If the problem comes from the mapid, how can I rename default 63240001, 63240002 to whatever values ? (I would like to be able to load Belgium maps with the France one).

Thanks,
Pierre

Hi Pierre,

Did you make sure that there is no other map on this device which contains equal mapids?
Since you use the default 63240001, 63240002 I wonder if you also created another map with one of these ids. If that is possible, make sure to use a different id simply rename the other gmapsupp files from *.img to e.g. *.img_
It is not sufficient to disable the map.

Hi John,

Thanks for your suggestion. But in my case, the same map of France coming from OpenTopoMap is working perfectly. So I don't think that the tiles limit has been reached.

Just a thought....

Is it a case of too many tiles on the device? Most devices have a limit on the number of tiles across all installed maps. Often c4000.

Hi Brico,

Does your newly created map displays in basecamp correctly?
If no: The start is to find out why tiles are skipped by mkgmap or splitter by investigating the error logging  (This is the tip of Ticker)
If yes: A start could be to disable all maps on your device by renaming the *.IMG extension to *._IMG except your own map.
You can find the maps on both the device as the SSD in the map garmin

If you created the maps the most straight forward way (without specifying family id and tile number start for example) you can easily create duplicate tile numbers which could conflict with other mapmakers. Default all tiles start with 6324xxx1

Yes, my GPSMAP 66s runs the latest firmware (4.20 see https://www8.garmin.com/support/download_details.jsp?id=14337).

Note that the France OpenTopoMap on the same device is working properly.

I can also try the map on my 64s if this can help to identify the problem...

does your device run the latest firmware? I had weird display problems
with older firmware on my 64s.

Subject: Re: [mkgmap-dev] Tiles missing

Hi Joris,

I didn't install the map in basecamp but if it can help, I will.

On my device I've moved all maps in a separated directories to disable them. The only one left was mine.

To create the France map, I started from belgium-latest.osm.pbf downloaded from geofabrik.de<http://geofabrik.de><http://geofabrik.de>. Then I splitted it using splitter (r597) tool and then generated the map with mkgmap (r4525). The mkgmap command line option was:

java -Xmx8G -jar $MKGMAP_DIR/mkgmap.jar --gmapsupp \
--family-id=$FAMILY_ID \
--product-id=0 \
--product-version=1 \
--draw-priority=20 \
--family-name="OSM $COUNTRY_ISO" \
--series-name="OSM $COUNTRY_ISO" \
--country-name="$COUNTRY" \
--country-abbr="$COUNTRY_ISO" \
--max-jobs=8 \
--latin1 \
--index \
--split-name-index \
--housenumbers \
--reduce-point-density=4 \
--reduce-point-density-polygon=8 \
--min-size-polygon=8 \
--polygon-size-limits="24:12, 18:10, 16:8, 14:4, 12:2, 11:0" \
--route \
--make-opposite-cycleways \
--add-pois-to-areas \
--process-destination \
--process-exits \
--order-by-decreasing-area \
--keep-going \
--style-file=$MKGMAP_DIR/resources/styles --style=default \
--bounds=$BOUNDS_FILE \
--precomp-sea=$SEA_FILE \
-c template.args ../typ/2000.typ \
--description="OSM custom routable(${COUNTRY_ISO}_$(date "+%d-%m-%Y"))"

with template.args coming from the splitter step.

Note that I've identified a (amongst several) missing tile and the name of the tile was in the template.args. Moreover, the tile which doesn't display on my device, is shown by GMapTool on the final IMG.

Thanks for your help,
Pierre
