OpenStreetMap improvements

Hi! I just pushed some big changes to OpenStreetMap.

• You can update OpenStreetMap without having to re-upload the maps
  
• The app uploader can now be run when OpenStreetMap is installed to manage maps and see which areas are recorded
  
• You can now have multiple map areas installed at once, and they can be different sizes and scales
  
• Support for much larger map areas uploaded than before
  
• The OpenStreetMap maps app can now zoom in and out (via a menu when you press the button)
  
• The currently recording track in the 'recorder' widget should now be plotted in the openstmap app if there is GPS - but I haven't been able to test this yet
  
  

... and a few more things. The quality of zooming is not amazing but this still seems like a huge improvement.

Really the main thing we need to sort out is the filtering of OSM maps into 3 bit color - if anyone has any contributions I'd love to see them (maybe it's best to start dithering)

Cool, multiple maps were on my wishlist.

Question: What does happen when multiple maps overlap? Which one gets the precedence?

Also there could be a bug with the recorder app when a map is uploaded with size != medium there seems to be a x,y offset. Can anyone reproduce this?

What does happen when multiple maps overlap? Which one gets the precedence?

They're drawn in order right now - so the one furthest down the list of maps gets drawn last. Potentially the uploader could have a way of sorting, or maybe we just sort so the smallest maps get loaded last?

Also there could be a bug with the recorder app when a map is uploaded with size != medium there seems to be a x,y offset. Can anyone reproduce this?

Recorder app? Or just the maps themselves? What kind of offset are you seeing? I did try testing it with multiple overlapping maps of different scales/sizes and they did appear to match up ok, but I guess something could be wrong.

I did spot an issue plotting tracks from the OpenStreetMap app, but that's fixed now.

How about preferring the map with highest zoom layer for a location?

About the offset:
I have attached two screenshots of the same track (recorder->select track->plot openstmap).
One with uploaded size = medium (second) and one with size = XL (first). The medium one looks plausible, the XL one has me cross the water (no I did not).

Versions: openstmap v0.15, recorder v0.19.

It seems that the current GPS position marker is offset from the correct position in OpenStreetMap, too.

Ok, so in that first image, you've got both maps showing? So you're zoomed out of the XL map, not 1:1?

Is that with an XL map too?

Yes, this was with an XL map.

Thanks - just found this, it was to do with the interface.html - should have a fix soon

Ok, should be fixed if you use the development app loader: https://espruino.github.io/BangleApps/

I'll get it in the main one tomorrow. I also allowed uploads of much bigger map sections (15x15) which end up being around a megabyte

Great. I will give it a try.

Looks good here, thx.
