Litchi Above-Ground to Google Elevation Converter Instructions

Instructions

This web application converts Litchi "Above Gound" heights to Google elevation heights.

In page one of Litchi Above-Ground to Google Elevation:
1. Use the file chooser to upload your CSV file.
2. Generate the mission and review the resulting parameters.
In page two of Litchi Above-Ground to Google Elevation:
1. Review the parameters and calculations.
2. Download the csv file.
In the Litchi Mission Hub:
1. Use the Missions menu to import the csv file created by Litchi Above-Ground to Google Elevation.
2. Do not select the "Above Ground" option for the waypoints as the above-ground height has already been computed and stored as the "Altitude" parameter.
3. Adjust the Litchi mission parameters (such as speed) as desired
4. Go fly!

When the "Above Ground" option is used in Litchi's Mission Hub an elevation API (Application Programming Interface) is used to obtain elevation data at that waypoint or POI. The height of that waypoint or POI is then adjusted so that the specified height becomes the "Above Ground" height at that waypoint or POI.

Google also provides an elevation API which provides similar, but different, elevation values from what are used in Litchi. Sometimes Litchi's and Google's elevation data agrees. Sometimes it does not.

This web application can be used to convert a Litchi mission that uses the Litchi "Above Ground" option to another Litchi mission that uses Google's elevation data instead.
