TERRACLIP

Service Status:OFFLINE

Generate Ardupilot mission files and auxiliary files (Stats file and export files). The output mission file contains WP's set to 'ABSOLUTE' heights for better mission previsibility and can be imported directly in Mission Planner.

  How it works

• Draw a path in GoogleEarth containing desired flight path. Export the path to a KMZ file (KML not implemented for input). Generated mission will respect the vertices from your path, converting vertices to WP's.
• Upload your KMZ file (or shapefile or geopackage or GDAL's driver ready file)
• Set parameters
• Hit 'process' button
• Your browser will download a ZIP file containing Ardupilot mission file; a Stats file and a KML 3D reference file
• The total area envelope of your input file should not exceed 400km² (server constraints)
• It will take some seconds (~10s) until you get the file downloaded the first time you hit 'process' button. Script is downloading necessary DEM from Open Topography (https://opentopography.org/). This is usually the querying time there.

• you can change parameters and hit 'process' again (and again) after first interaction. Script will use a buffered version of necessary DEM until you upload a new file or hit browser refresh.

  <flight ALT> => Flight altitude above ground. This will be the minimal altitude to be respected along all path
  <Tolerance> => Flight altitude tolerance (in %). Means Minimal altitude along path can reach <flightAlt> minus tolerance
  <Max Distance Between WPs> => Divide your original WP's into sections (creating another WP's), respecting this max distance between WP's. The lower this parameter the more a 'terrain following' effect. Set this to zero to not create any aditional WP's.
  Takeoff => Optional. Converts the first WP's from your file into Takeoff command
  Land => Optional. Converts the last WP from your file into Land command.

  Features

• Anti-collision check, guarantees minimal altitude above ground along all flight path
• Doesn't care about your vector/DEM input files DATUM/CRS, converts accordingly
• Outputs a stat file containing minimal flight altitude, max flight altitude, max generated inclination and suggested RTL_ALT (max DEM scene altitude plus <flightAlt>)
