# Flightplans ## What are flightplans? A flightplan is just a list of flightlines, and each flightline consists of a list of waypoints. Flightlines with static height can contain of just 2 waypoints (beginnning and end), whereas terrain-following flightlines ususally consist of waypoints spaced at an even interval. SpatialExplorer can import and manage multiple flightplans at the same time. ## How to import a flightplan Flightplans can be created using , Topoflight Planner or simply by drawing and exporting paths/lines (LineStrings in KML terminology) in Google Earth. To open a flightplan, ensure the project panel is visible (Windows->Project), then select Flightplans in the tree view and click the file-open button at the bottom. ![Flightplans section in the project panel before loading a flightplan](/files/-MkOqZlSE_LmqZajWspZ) Select the KML or KMZ file to import, and use the latest WGS84 realization to import (EPSG 1156). ![](/files/-MkOqyhXmPh8AjPfqTrP) Above dialog allows importing only specific KML-folders, and also allows filtering the geometry type. Select the folder(s) containing the flightline's LineStrings, and leave the import geometry types at LineStrings. Press OK. ![](/files/-MkOr5Z4yVTaOqDwGTVX) The flightplan has now been imported: ![](/files/-MkOrM1_0kzAjokOcGYq) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
