use MapDroyd offline maps for track display background #126

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I have both this and MapDroyd installed. MapDroyd downloaded several maps for 
offline usage. It would be great if one could use them anywhere as background 
for gps track display, even if there is no data connection available.

Hi,

Thanks for the suggestion. I can see how it would be beneficial when you can 
see the sky but not a cell or WIFI tower. 

OSMTracker's map view uses a tile renderer produced by the guys who make 
OSMDroid (https://code.google.com/p/osmdroid/). This is a tile based renderer.

As far as I am aware, the MapDroyd maps are not tiles but compressed map data 
that allows the map to be generated dynamically on the device. The format used 
is called MicroMap 
(http://www.onestepahead.de/index.php?option=com_content&view=article&id=96:micr
omap&catid=72:micromap&Itemid=62)

To support this functionality, OSMTracker would need a new view capable of 
rendering that data. This would involve either writing a renderer (might take 
some time) or including a third party renderer (maybe MapDroyd have a library 
that can be embedded).

So, it's not impossible to support these maps, but it would require someone who 
was prepared to spend the time investigating the options and integrate it into 
OSMTracker. 

There might issues in relation to OSMTracker downloading the MapDroyd data so 
that may be something the need to be cleared also.

Hi,

OSMDroid (the renderer used in OSMTracker) should be capable to use offline 
maps as well (currently not tested).

But you could have a look at issue#113 there is a link that explains how it 
should work. (if you have the time and motivation)

best regards
Matthias

Hi,
Is it possible to add a dialog for change offline map data location?
I'm using osmand and it would be nice to use this data.

First of all OSM Tracker is an awesome app, so I am grateful for every feature 
it has right now.

The only missing thing for me is support for offline OSM maps (vector ones). So 
if this request "use MapDroyd offline maps for track display background" move 
to "use offline maps for track display background" (MapDroyd dropped) I am all 
for it.

Another osmand user ... would be great to be able to share the offline vector 
data from that app. I use a tablet, not a phone, and in any case there's no 
data reception in most of the places where I make track logs (hiking trails and 
remote dirt roads).
