raster classing problem

[Christopher Condit]

Hi all-

I've having a problem classifying AAI/Grid raster images.  It's probably
a precision issue, but I'm not sure how to fix it.  In this class, I've
classed a very small range of data values into 30 stratifications - none
of which are rendered, even though data falls into the range of one of
the classes.  

 

I'm attaching a simple test case to illustrate my problem.

1)       o2.txt is the AAI/Grid file

2)       session_work.map is a mapfile that draws the raster with no
classes.  This works fine

3)       session.map is a mapfile that has classes, but generates no
output.

 

Thanks!

 

Chris
