Jan Mayen (ENJA) has no elevation

[jonaseberle]

For the Arctic explorers...

Jan Mayen (ENJA) also has zero elevation in the current Viewfinderpanorama mesh.

Funnily I was not able to fix it with Sonny although it has data.
I don't know, somehow Ortho4XP is not able to process the data.

+71-009 with Sonny DTM:

[Ortho4XP/Tiles/*/*/*/+71-009.dsf]
...
Available elevation data for this tile before Ortho4XP run (25M is HD 1", 2.8M is 3"):
25M Ortho4XP/Elevation_data/N71W009.hgt
...
   Loading elevation data and smoothing it over airports.
    * Min altitude: 0.0 , Max altitude: 0.0 , Mean: 0.0

I'll leave it like that for now.
I am just leaving that information here to maybe revisit it later.

Build tiles for Jan Mayen:

for lat in {70..71}; do 
  for lon in {-10..-8}; do 
    make -f Makefile.tiles z_aosingle_$(printf "%+03d%+04d" "$lat" "$lon").zip
  done
done
