leave this screen and use the app for other things. However, if the app is closed, then the
download will fail. If the download fails for any reason, then the app will attempt to
redownload the elevation maps once every minute. Once the elevation map download for
the region completes, the “No elevation data” note on the right side of the screen will
change to “Full elevation data”.
Each elevation map file covers a large area of 1 degree of longitude by 1 degree of
latitude, and requires between 1 and 15 Megabytes of storage space. These files are stored
on your mobile device in the directory /Drone Amplified/Elevation Maps. You can free up
storage space by deleting this directory or the individual elevation map files within it.
We would like to note that the ability of the app to download elevation map files from our
servers will not be a free feature once the app leaves its open beta state, but it is provided
for free during the open beta for testing.
7.5.2 Managing Regions
Each downloaded region appears in a list below the “NEW OFFLINE REGION” button.
These entries give some basic information about the location, size, and zoom levels of the
map. If an entry in the list is touched, it will expand to display the progress of any
downloads related to it, as well as display “VIEW”, “RENAME”, and “DELETE” buttons.
Pressing the “DELETE” button will start the deletion process for that region. Please wait
until the deletion is completed. This button can also be used to stop downloading satellite
imagery for a region.
Any number of regions can be downloaded, but there is a limit to the number of map
tiles that are allowed to be saved by Mapbox. If the download fails because the Mapbox Tile
Count limit was exceeded, try deleting a few other regions to free up space.
Pressing the “RENAME” button will allow you to rename the region so you can easily
identify it later. Once you are done typing in the new name for the region, press the “SAVE
CHANGES” button to save the new name, or press the “CANCEL CHANGES” button to go
back to the previous name.
