Re: Offline OSM vector file plugin to edit in the field - OBF vector format or other

[Pierre Béland]

Hi Dirk
What I suggest is that JOSM adapt to different operational context out of our 
northern countries with high speed internet. To navigate with OSM in JOSM 
should be as easier as smarthpone offline applications for people that need to 
work offline because of bad / expensive access to internet networks.  My 
experience with smarthpones applications is that they are reliable, they 
provide fluidity. JOSM Caching is surely not as easy and reliable as these 
offline maps.  And badly, moving in an area with no internet connection, you 
realize that your setups are not ok and you have no background imagery.

I agree that Obf is not a standard. The best would be that one standard emerge 
for offline vector files.
In the meantime, what can we do to adapt to all the countries / areas without 
high internet inexpensive bandwith?

I don't understand what you request at all.

- JOSM has tile caches which usually are small, but you can increase size
- JOSM is an vector map editor - its main task is to display vector data
- JOSM can load stored offline data files in XML and also PBF format

Everything already there.

OBF support could be included in a plugin, but I don't see much sense to 
support a storage format of a single application.

Offline OSM vector file plugin to edit in the field - OBF vector format or other

[Pierre Béland]

In the last few weeks, I was in Haiti with either intermittent access to 
internet or shorten bandwith. 
In Africa, Haiti and many other countries, access to internet is often 
difficult and expensive. We either have a narrow bandwith, intermitent or no 
access. While oing to remote areas in the mountains for field data collection, 
we simply had no access to internet. 

Smarthphones did provide us access to all of Haiti on OSMAnnd or Maps.Me. Our 
team was able to store tracks and waypoints on our phones. We did also use 
Mapillary and ODK tools. But at the end of the day, we could not edit the data 
in JOSM, bringing in these various infos to compare with the OSM map as a 
background. This, even if I tried previously to cache OSM tiles for the area, I 
did not have access to these tiles while in the field with no internet access.
A cache could be a solution. A better solution is to Add an Offline OSM Vector 
map plugin to JOSM. This would be a great enhancement for OSM contributors that 
experience difficulty to access data online.
