ProMark Field then browses all the folders in search of all
the image files stored in the receiver meeting the current
Type selection.
• Select the name of the image file you want to add. This
automatically adds the file to the list of background maps.
A message will warn you if you are attempting to add an
already georeferenced background map that uses a
coordinate system different from the one used in the open
job.
In contrast, adding a background map in OSM format will
never raise a warning message because, although
originally in WGS84, the OSM file will be transformed to
be always matching the coordinate system of the open job.
•Tap OK to return to the map screen. Note that the map
screen will show the background map(s) only after the
receiver can compute a position. Remember you may also
have to press the ESC button (ProMark 100 or 200 only)
so that the map screen can show the location of the first
logged feature.
Georeferencing an
Image File
Georeferencing an image file means defining at least three
reference points giving the position of the image in space.
Defining a reference point means entering its precise X-Y-Z or
Lat-Lon-Height coordinates depending on the coordinate
system used in the currently open job.
The larger the number of reference points you define, the
more evenly distributed these points over the entire image,
the better the georeferencing of the image.
To georeference an image, do the following after adding it to
the list of available background maps:
