Given a previously generated suitable area, the HLZ Touchdown Points tool is used to create two feature classes containing possible touchdown point circles and center points for a selected aircraft.
To analyze possible touchdown point circles and center points, identify the following:
- Input Airframe Specification Table - This table contains the aircraft specifications.
- Select the table from the map, or
- Provide your own specification table with the same attribute fields.
- Airframe - The type of airframe for which the touchdown points should be generated.
- Select the airframe you want to analyze.
- Input Suitable Areas - The layer containing the polygon features that have been identified by previous analysis as being suitable for helicopter landing zones.
- Select the SuitableAreas layer that is in the map, or
- Browse to a suitable areas vector.
- Input Slope - The input slope raster.
- Select the slope layer that is in the map, or
- Browse to an slope raster.
- Output Geodatabase - The geodatabase in which the touchdown points generated will be stored.
- Output TDP Centerpoint Features - The feature class that will contain the center points of the touchdown points.
- Output TDP Circle Features - The feature class that will contain the buffer circles around the touchdown point centers.
