#107 Ability to download tiles around a gpx

[Anonymous]

I would like the ability to download tiles of selected zoom level around a defined gpx, up to say some selectable radius. Sometimes I'm traveling city to city and not planning to go outside the route and if the route is not roughly horizontal or vertical (in the screen) I end up selecting lot's of superimposed squares that are either suboptimal because I download too much, or get tired of selecting the stair-step of small squares.

If you know JOSM, one of the OpenStreetMaps editor, it has a feature to download OSM data around a GPX track to help editing, is something like that.

This would also be very suitable for me. I use the Openstreetmap as the primary map for my geocaching activities. I once wrote a simple Java program that reads a GPX file (whether it be a Geocaching GPX, a track log or a route) and download all the tiles + all their neighboring tiles of all zoom levels. This way I have very detailed maps near the cache (close to the route) and less detailed maps further away. I've attached my program. If I have time to digg into the Mobile Atlas Creator details (certainly within the next few months), I'll see if it is possible to integrate it into MOBAC.

Hmm, file uploading does not work for me. The Java application can be downloaded from http://depositfiles.com/files/7sm2spcdb instead.

A first experimental version of MOBAC has just been released that has the ability to define polygonal maps based on a GPX track segment.

1. Load a GPX track in the GPX editor that has at least one track with a track-segment.
2. Select in the GPX tree the track-segment you want to use. I recommend that it has a maximum of 50 track points.
3. Select the maximum zoom levels the distance around the track is currently hard-coded to 50 pixels according to the smallest zoom level.
4. Activate the menu entry "Maps" -> "Add selection by GPX track"
5. You can see the created areas by selecting "Display selected areas" from the context menu of the created Layer in the atlas content tree.

Upon creation of polygonal maps you may encounter error messages about missing tiles - just ignore them.
Please try it and respond back your experiences.

Implemented in v1.9 beta 5.

is working very well in most current V1.9 and V2.0 beta 2 (I use)

and further I found here what I was wondering about(
"the distance around the track is currently hard-coded to 50 pixels according to the smallest zoom level.").

I'm missing to influence this value, because on some tracks it IMO would make sense to cover a wider range around, although having a deep zoom level. Is there a chance that you make this configurable (best would be the dialog which pops up before adding selection around the track.
