murata f04cab917b AP_Terrain: Explicitly state that they are at the same latitude 2023-02-08 08:54:35 +11:00
Peter Barker 84215ff662 AP_Terrain: only include GCS_MAVLink if terrain is enabled 2023-01-03 10:47:28 +11:00
Andrew Tridgell 5f2c5be84a AP_Terrain: added terrain reference adjustment
this restores the terrain adjustment functionality removed in #19946,
but without the problematic approach of always using home (which can
be moved in flight) and with a TERR_OFS_MAX parameter to limit the
amount of adjustment

Andrew Tridgell 227609eef0 AP_Terrain: allow download of terrain data when no GPS lock
this fixes several issues:

 - allows users to download terrain data at home with no GPS lock

 - allows for a TERRAIN_CHECK without GPS lock

 - retries opening of files every 5 seconds to allow for remount of sd
   card after boot

Andrew Tridgell 7b7bf3ef86 AP_Terrain: fixed bug in disk offset calculation
this fixes a problem where two different locations could both be
mapped to the same disk block in the terrain/*.DAT files. That meant
that pre-filled terrain on the microSD card would sometimes require a
download in flight. It also means that a RTL with loss of GCS could
sometimes fly through a region with no terrain data available

Other changes in this patch:

 - allow for a 2cm discrepancy in the lat/lon of the grid
   corners. This is needed to allow for slightly different floating
   point rounding in tools that pre-generate terrain data to load on
   the microSD

 - added TERRAIN_OPTIONS parameter to allow the user to disable
   attempts to download new terrain data. This is mostly useful for
   testing to validate a terrain generator

Lucas De Marchi 4936fd8623 AP_Terrain: add O_CLOEXEC in places missing it
By opening with O_CLOEXEC we make sure we don't leak the file descriptor
when we are exec'ing or calling out subprograms. Right now we currently
don't do it so there's no harm, but it's good practice in Linux to have
it.

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

Gustavo Jose de Sousa fcd1d4938a AP_Terrain: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Functor is not yet being used but let's make is macro fallback to the
previous Delegate implementation for easy of transition between the two.
