Re: [Paparazzi-devel] Google Maps in Maverick

[Reto Büttner]

Hi Felix,

thanks for your research. I updated from git.

I can load now high resolution tiles in my area using the maps policy
"NoCache". The download is very slow, maybe three to four tiles per
minute. Although I have a fast internet connection. Last year the
tiles just popped up when I downloaded them. With every tile I get a
message in the Paparazzi Center:

Bringing up some patience I get my pilotage area filled. But the maps
are not stored in the cache. When I restart the GCS I cannot reload
the high resolution tiles from cache using maps policy NoHttp. Then I
only get the useless low resolution background picture. Sometimes when
I pan or zoom I get an error message describing a corrupt map file,
asking to delete it.

I can select other map sources, the behaviour stays the same. I get
the following messages:

Any ideas how to get maps working smoothly in high resolution and from cache?

SRTM still doesn't work. When I select it in the menu, I get the
following error message:

"SRTM tile N46E008 not found: download
http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/???/N47E008.hgt.zip in
data/srtm/ ?"

When I click Ok, nothing happens and the SRTM display remains zero. Any ideas?

Cheers, Reto
