Dear Jemima,

 

Yes, it is possible to use MGET to detect fronts without having ArcGIS. In order to do it, you will have to write some code in Python or another programming language that can call MGET functions.

 

First, you will need to install these things:

 

·         Python 2.5 for 32-bit Microsoft Windows (any version of Python 2.5 will work; I suggest the latest released for Windows, 2.5.4).

·         pywin32 for Python 2.5 (use the latest version)

·         numpy for Python 2.5 (use any version up to 1.4.1)

·         MGET for Python 2.5 (use the latest version)

 

Then you will have to write a program that calls one of MGET’s functions to find fronts. You have two options:

 

·         DetectEdgesInSingleImage – use this function to find fronts in a numpy array. numpy is the most popular Python package for working with array data. You will have to use MGET, numpy, or other packages such as GDAL to read the remote sensing images from files produced by SeaDAS (or whatever) and then call this MGET function.

 

·         DetectEdgesInBinaryRaster – use this function to find fronts in a binary file. In this scenario, you would use SeaDAS, MGET, or other utilities to save the remote sensing images as plain binary files, and then call this MGET function to read the file and find the fronts. The output is also in the form of binary files, which you would have to read and display using other software.

 

There are some general examples on calling MGET functions here.

 

I am going on vacation and will be unable to respond to email from August 14-29. If you have further questions, I will reply as soon as I can after I return.

 

Best regards,
