Horseshoe bat flight line predictor!

Horseshoe Bat
Flight Line

  1. Check the tutorial for more information
  2. Pinpoint your roost
  3. Import street light data if available
  4. Draw buildings, roads, or street lights
  5. Generate maps showing modelled flight lines and/or
    the difficulty bats encounter moving through the landscape

For large areas, numbers of lights, or complex shapes,
please be patient.

Upload a CSV file with lamp positions (easting, northing, height)

Warning: please read this paper before altering these parameters, or leave as defaults.


Locate point on the map or enter coordinates





Warning: please check the LIDAR data coverage before generating resistance maps


To upload a CSV file for lamp data select Street Lights, and click the upload button. This data should have three columns x, y, and z. Lamp CSVs should only cover the study area. If you require an extremely large number of lamps, contact the administrator.

To adjust parameters used for resistance map calculation, select Resistance Parameters, followed by the parameter you wish to adjust.

To adjust the radius analysed, select Roost. Note that, the larger the radius selected, the smaller the permissible resolution. If a high resolution run is required for a large radius, please contact the administrators.

To draw buildings, rivers, roads, or street lamps directly onto the map, select Drawings, click the add button, and select the tick box. Parameters for an individual component can be adjusted by selecting the panel. Note that the height of a building relative to lamp height will affect light occlusion. A string of lights can be created by selecting light string, and the chosen spacing.

To generate a resistance map, select Raster, select your chosen resolution and the number of source circles, and then click generate. Resistance maps can be downloaded without running circuitscape.

After resistance map generation, to run circuitscape, click Generate Current Map. Note that for high resolution images, this step can take several minutes to an hour. Please be patient.
