Site Selection for Helicopter Landings

4 posts in this topic Last Reply

Recommended Posts

Hi there

I'm trying to build a "model" that could do our job a bit easier in the field. I want it to find the most suitable place for a Helicopter to land. I want it to do it based on a DEM 1.6m and to locate sites with 25x25 pixels, 100x100 pixels, 1500x1500 pixels and with no obstacles.

Any ideas of "how to begin" the project ????

hem, first you need to list the variable for those model, and after that what source of data for the variable

DEM will be good for topography, you need a flat land to make a landing pad, but there is another variable that still need to consider

I used the DEM to find a slope at max. 7degree.

I used all the obstacles (FC converted to raster) as a mask.

I exstract these from each other and has now a raster with properly usable terrain.

But when i want to find 100x100 pixels in this (160meter x 160meters square for a large Helicopter) raster with the tools i know of, it finds 10.000 pixels and this could be 1 x10000 or 25 x 400 etc........I can't seem to force it to 100x100 as a square or cirkel.

Anyone ?
