Greetings All,
I'm new to MI but have already had to confront what seems to be a
non-trivial problem. I need to convert a global landcover classification
file into a table of MI regions. The file is described as being in a
"geographic coordinate system (also known as Plate Carree or
latitude/longitude)". My examination of the file has determined that it
consists of binary data arranged in 5760 byte/pixels per line of 2880 lines.
Each line represents a parallel of latitude with the lines arranged from the
North to South Poles. Each pixel represents the landcover classification
within a .0625 degree square zone of longitude and latitude. The pixels of
each line run from -180 to +180 degrees longitude.
I would like to use this file to generate a table of regions of homogenous
coverage, i.e. essentially determine the boundaries of groups of contiguous,
identically valued pixels. I've started to write my own program to perform
this transformation (I work in VBA in Excel) but fear that it will take too
long before I finish and debug this massive effort.
I was wondering if MI has a feature for directly reading and converting such
a file and only my lack of experience has kept me from finding it?
Alternately, does anyone know of an MI "plug-in" or auxiliary tool which
performs the transform?
