Re: [Paparazzi-devel] Google Maps in Maverick

[Bernard Davison]

Further to this i've just pushed some make file additions that let you "build" the SRTM file.

i.e. make S33E151.hgt.zip Q=""

I'm thinking that this could be added as a target based on the location from the flight plan.

Then you could just change the location of your flight plan and build and it would be downloaded for you.

Though I'm not sure if it's possible.

Cheers,

Bernie.

Felix. the working out where to download should be fairly simple actually.

if we download the directory listing for each of the areas into some data files.

i.e. add something like this to the top level make file.

SRTMData: conf/srtm_data/Africa conf/srtm_data/Australia conf/srtm_data/Eurasia conf/srtm_data/Islands conf/srtm_data/North_America conf/srtm_data/South_America

conf/srtm_data/Africa:

        wget -O $(@) http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/$(@F)

conf/srtm_data/Australia:

        wget -O $(@) http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/$(@F)

conf/srtm_data/Eurasia:

        wget -O $(@) http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/$(@F)

conf/srtm_data/Islands:

        wget -O $(@) http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/$(@F)

conf/srtm_data/North_America:

        wget -O $(@) http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/$(@F)

conf/srtm_data/South_America:

        wget -O $(@) http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/$(@F)

then we can do something like

grep -l N01W054.hgt.zip conf/srtm_data/*

with a little bit of parsing this could be made to just the required name

i.e. grep -l N01W054.hgt.zip conf/srtm_data/* | sed -e s#conf/srtm_data/##

But how this would go into the program I don't know.

Cheers,

Bernie.

Hi again,

I just had a quick look at the loading of the SRTM data and the popup that you get.
It seems that Pascal removed the automatic download of SRTM data in 2006 when he changed it so it actually works for the southern hemisphere as well. So the data was automatically downloaded then (it was assumed that you wanted it from Eurasia), but he just changed it to a message.

So we should either figure out how to decide where to download from or maybe just try all regions till we find the data we are looking for.

Until you will have to download it yourself and put it in the data/srtm folder.

Cheers, Felix

Hi Reto,

map tile download was quite fast for me here...
These messages indicate which map tiles are downloaded (and stored). I guess someone with more knowledge in ocaml has to look at why they are not properly loaded anymore. (Did you check if these tile were actually stored in var/maps?)

Regarding the SRTM data, this is obvious: as the error message indicates you don't have the SRTM data you are trying to load!
You need to download the data and place it in your data/srtm folder.
See http://paparazzi.enac.fr/wiki/Maps#Getting_and_using_SRTM_Data

I hope that someone will soon write a nice routine that asks you if you want to download the data (you still have to figure out where to download it from, e.g. Africa or Eurasia...) and then stores it in your data/srtm folder.

Cheers, Felix

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
