MATLAB: GeographicToIntrinsic is not installed

Mapping Toolbox

I don't appear to have the function geographicToInstrinsic, despite having the Mapping Toolbox installed:

> ls /Applications/MATLAB_R2019b.app/toolbox/map/*/geographicToInstrinsic.m

ls: /Applications/MATLAB_R2019b.app/toolbox/map/*/geographicToInstrinsic.m: No such file or directory

Other mapping toolbox functions are installed. For example:

> ls /Applications/MATLAB_R2019b.app/toolbox/map/*/geod2iso.m

/Applications/MATLAB_R2019b.app/toolbox/map/map/geod2iso.m

I also have the same problem on another machine that has MATLAB 2018A.

Should be in both since the docs say "Introduced in R2013b".

Confusing!

Hi,

You can find the implementation of 'geographicToIntrinsic' in the following file: matlab\toolbox\map\map\+map\+rasterref\GeographicRasterReference.m

'geographicToIntrinsic' expects it's first argument to be a GeographicCellsReference. Only then you will be able to call this method.

You can run this snippet:

R = georefcells();
geographicToIntrinsic(R);

This will give you an error, as it can locate the function now under GeographicRasterReference file.

Hope this helps!

This occurs because the function "geographicToIntrinsic" is located in the "GeographicRasterReference" class rather than its own m-file. To find the location of this class, you can execute the following code:

>> russia = load('russia','map','refvec');
>> R = refvecToGeoRasterReference(russia.refvec, size(russia.map));
>> R.LatitudeLimits;
>> R.LongitudeLimits;
>> xIntrinsic = 79;
>> yIntrinsic = 23;
>> [lat, lon] = intrinsicToGeographic(R, xIntrinsic, yIntrinsic);
>> [x, y] = geographicToIntrinsic(R, lat, lon);
>> which -all geographicToIntrinsic

The function definition for "geographicToIntrinsic" can be found in the GeographicRasterReference.m file.

MATLAB: Geographic coordinate to Image coordinate

You should use the georasterref function to create geographic raster reference object. For example,

R = georasterref('LatitudeLimits', [27 28], 'LongitudeLimits', [86 87],'RasterSize', [121 121])

The raster size is your image size. The documentation for georasterref can be found here.

Then you can use the function geographicToIntrinsic to obtain the intrinsic coordinates. The function can be called as,

[xIntrinsic, yIntrinsic] = geographicToIntrinsic(R,lat, lon)

The documentation for geographicToIntrinsic is found here
