• Tap in the Type field and select the format of the file

containing the background map:

– Open StreetMap (osm)

–Bitmap (bmp)

– GIF (gif)

– GeoTIFF (tif)

– JPEG (jpg)

– JPEG2000 (jp2)

MobileMapper 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.

Like layers, each of the added background maps can be

shown or hidden on the map screen. Set accordingly each

of the check boxes placed before the names of the

background maps (cleared= hidden, ticked= shown).

•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 (MobileMapper 100 only) so

that the map screen can show the location of the first

logged feature.
