MATLAB: How to read multiple dted files using Mapping Toolbox

dtedmappingMapping Toolbox

I have multiple dted files in a directory and I want to read these files at once. Is this possible?

It is possible to read multiple dted files at once using DTED command in Mapping toolbox.If latitude limits, longitude limits and Sample factor are known then DTED command can be used. An illustration is as follows:

If the location of the folder for dted files is 'C:\SampleFiles' then use DTED command as shown:

latlim = [30.1  31.5];
lonlim = [35.0   35.9];
samplefactor = 5;
[capetopo,caperef] = dted(‘C:’, samplefactor, latlim, lonlim);  %  include only  C: drive                                                                                           % in the path

Note: If 'SampleFiles' folder is included in path it brings up a GUI and asks the user to select the files manually.

The syntax for kmlwrite is:

kmlwriteline(filename,latitude,longitude,altitude);

The fourth variable passed is considered as altitude data. In your case you can create an array with multiple lat and lon points and send that array to the function.

Try this:

lat_points = [lat1;lat2;lat3;lat4];
lon_points = [lon1;lon2;lon3;lon4];
kmlwriteline(filename,lat_points,lon_points);

Hope this helps.

MATLAB: Do I receive an error when attempting to use the DTED command to read files within a directory in Mapping Toolbox 3.0 (R2009b)

This error occurs when the DTED function is called with the path to the 'dted' directory. Instead, please specify the path to the parent directory of the 'dted' directory as the 'dirname' input into the DTED function.

data = dted('C:\files', 1, [32 33], [-97.3 -97.5]);
