3.4 Measure distance and work with geometry

Measure between map points on every platform. Ok2Fly Web also provides subscriber tools for tracks and polygons, while Apple can load a prepared operation geometry.

A track connects a start point, intermediate waypoints and an end point. Its configured buffer represents the intended lateral area or uncertainty. A polygon represents an irregular operation area and remains closed as vertices are added.

Draw and check a flight area

Web

1. Enable Geometry Tools.
2. Select Draw Track or Draw Polygon.
3. Select points on the map to create the geometry, then finish the drawing.
4. Select the saved geometry and choose Query.
5. Review the complete flight-check result for the buffered area.

Import a geometry file

Web

1. Select Load Geometry File.
2. Choose a .geojson, .kml, .gpx, .csv or .kmz file.
3. For CSV, provide at least two rows containing Name, Latitude, Longitude and optional altitude and waypoint values.
4. Confirm that the imported geometry is correctly positioned before checking it.

Import an operation geometry

Apple

Load the file from Ok2Fly

1. Select Layers on the map.
2. Scroll to Geometry at the bottom of Map Options.
3. Select Load GeoJSON File.
4. In Files, locate and select the GeoJSON or KML file. A remotely stored file may need to download before it can be selected.
5. Wait for Ok2Fly to display the geometry and centre the map on it.
6. Select the geometry and choose Query Area to check its buffered area.

Apple

Query a loaded operation geometry

Open the file from Files

1. Open Files on the iPhone or iPad.
2. Locate and select the GeoJSON or KML file.
3. If prompted, choose Ok2Fly as the destination app.
4. Return to Ok2Fly and inspect the complete geometry before querying or using it in an operation plan.

Edit or export saved geometry

Web

Select a saved track or polygon, then use the applicable control:

• Edit changes its points.
• Rename accepts letters, numbers, spaces, underscores and hyphens.
• Change Color changes its map colour.
• Save exports it using the configured filename and format.

WARNING

Delete removes the selected geometry. Clear ALL Saved Geometries removes every saved geometry. Confirm the intended scope before continuing.
