i am on a project in matlab where my code has to decide whether a image of land is agricultural. image should be a top satellite view of the land. combining functionality of land and matlab workspace i found only one relation that is of color of land in image. how to proceed with the project.

You need to do some more research first into multispectral remote sensing algorithm. For that, go here: http://iris.usc.edu/Vision-Notes/bibliography/contentscartog.html#Cartography,%20Aerial%20Images,%20Remote%20Sensing,%20Buildings,%20Roads,%20Terrain,%20ATR. Once you pick an algorithm and code it up, we can help you with the MATLAB code. We don't do complicated algorithm development here.

What about them? You get the name from the edit field and pass it to your m-file like I already showed you.
theURLFilename = get(handles.editLink, 'String');
theImage = imread(theURLFilename);
[out1, out2] = other_m_file(theImage , in2, in3); % or whatever...
Or you can pass just the filename string into your m-file instead of the image array after it's been read in:
theURLFilename = get(handles.editLink, 'String');
[out1, out2] = other_m_file(theURLFilename , in2, in3); % or whatever...
It's really however you want to do it.

May or may not be useful for you, but the latest issue of the IEEE Signal Processing Magazine is entirely dedicated to hyperspectral remote sensing and classification.
