How to convert .mat file to .tif file?

Hi all,

Is there any way to convert .mat file to .tif file? Since I had made some change in the grid cell and save as .mat file, I need to convert the .mat to .tif file for ArcGIS. However, I cannot find the effective way to convert this.

I highly appreciate your help and assistance.

Thanks, Pich

You have to load data from .mat into matlab and then convert it into .tif.

Let data be your matrix and xmin, xmax , ymin, ymax be minimum and maximum longitudes and latitudes respectively. You can convert this data into .tif file using:

% Write the data into geotiff 
R = georasterref('RasterSize',size(data),'LatitudeLimits',[ymin,ymax],'LongitudeLimits',[xmin,xmax]);
geotiffwrite('myfile.tif',data,R)
%%Read geotiff file
[A, R] = geotiffread(tiffile);
figure
mapshow(A, R);

Dear KSSV

I am using your scripts and it looks good. But I cannot see the map using the command "mapshow(A, R)".

 Moreover, when I take the 'myfile.tif' file into arcGIS, the Map is upside down and cannot be correct. COuld you give some comments.

Thank you

You have to post your data and the code which you tried.

The code is yours and I simply chnage the maximum and minimum limits of latitude and longitude, Sir. here it is.

% Write the data into geotiff R = georasterref('RasterSize',size(T),'LatitudeLimits',[7,12.57],'LongitudeLimits',[34,39.87]); geotiffwrite('myfile.tif',data,R) %% Read geotiff file [A, R] = geotiffread(tiffile); figure mapshow(A, R);
