I am trying to replicate the “Planning Radar Network Coverage over Terrain” example in MATLAB and want to know how can I change the region of this example?

7 vues (au cours des 30 derniers jours)
So as the question asks, I want to change the region of this example from southboulder, TX to any other region, for instance new york. How can I do that? So far I have tried:
dtedfile = "n39_w106_3arc_v2.dt1";
attribution = "SRTM 3 arc-second resolution. Data available from the U.S. Geological Survey.";
addCustomTerrain("newyork", dtedfile, "Attribution", attribution)
viewer = siteviewer("terrain", "newyork");
nyork_peak = txsite("Name", "newyork", ...
"Latitude", (#), ...
"Longitude", (#) );
>> show(nyork_peak)
After executing the last comment, I encounter an error:
Error using terrain.internal.TerrainSource/tileInterpolation
Terrain 'new york' is limited to latitudes in range [39,40] and longitudes in range [-106,-105].
Error in terrain.internal.TerrainSource/query

You need the correct SRTM elevation file for the area you're interested in. These DTED files are only 1x1 degree. You're specifying a lat/lon outside what that file has. The 'n39_w106' in the prefix of the filename tells you the lower left corner. I suggesting searching how to get the data. It's a bit of a pain if you want the whole set. USGS Earth Explorer seems set up to prevent users from grabbing datasets in bulk.

I downloaded one particular DTED file, but how do I add to script

Chang the name of the dtedfile variable to match your new file. Then, make sure the site you specify via txsite is within that file's area.
