eMotion in-depth guide
You can select the background map source from the drop-down list in the Toolbar,
and adjust its zoom level using the and buttons. eMotion can use many
sources of commercially available and custom mapping information. Tiles from
map sources with the icon are downloaded by eMotion from the Internet as
required and locally cached on the hard drive. Due to regulatory restrictions, map
sources with the icon cannot be saved locally and are not recommended for
use in the field.
If you anticipate the use of eMotion in conditions where connecting to Internet is
impossible, you can preload the map data by selecting ‘Download maps...’ from
the File menu. Follow the instructions in the dialog box to select the zone of
interest, map tile source and start downloading.
eMotion can also import and display custom layers which may include KML files,
custom map tiles and elevation data. To import a KML file, select ‘Import KML...’
from the File menu and select your KML file. The resulting layer will now be
available in the Toolbar by clicking on the icon, and can be clicked to display or
hide it. eMotion can display lines, polygons, paths and points savedin KML format.
Note: KML files, including associatedicons or images included within
them, are not copied to the eMotion directory and will no longer ap-
pear in eMotion if the original KML files are deleted.
Custom map tiles can also be added as a layer in eMotion. Select ‘Import custom
map...’ from the File menu and select the folder that contains the tile set. The
tile set will then appear in the list of layers in the Toolbar, accessible by clicking
the button.
Note: If you use Postflight Terra 3D (see section ‘Processing image
data’ on page 48), a tile set can be generated for each project that
is directly compatible with eMotion. You can therefore create your
own map background using the eBee. You can generate the tile set
by selecting ‘Generate Google Maps tiles and KML’ from the ‘Process’
menu within Postflight Terra 3D.
Whenever the eBee takes a picture, eMotion records the location and orientation
of the drone and computes the approximate span of the photo on the ground (or
