RASTER Layer.

[Owens, Ryan J NWD02 CONTRACTOR]

Ed,

 

This is a bit overdue... but thanks for your assistance with my question.  I
was able to get the raster layer to function properly.

 

Another question... do spaces in a map file cause problems?  In other words,
am I creating problems when I am trying to make a map file more readable by
realigning code and adding spaces?

 

Ryan

Ryan -

 

The example MAP file you give seems (at a quick look) OK if all your input
data is in the same projection.  The only way you know what projections to
use is by knowing your source data.  Some source formats, like GeoTIFF, will
have projection information embedded in them.  Others, like your shapefiles,
usually do not - you need to know what you have.

 

Do you think all your data is in the same projection?  What does the listgeo
command tell you when you use it to dump the metadata from the basin_alb.tif
file?

 

I'm going to guess that your raster image is in the Albers or other
projection, and your shapefiles are in unprojected geographic coordinates.

Hello Listserv,

I'm new to Map Server and I am having some difficulties with getting a raster
output to work.  So far I have been able to get a TYPE LINE output to work.
I want to add another layer, a RASTER layer, but it does not work and I don't
know what I am doing wrong.  Will someone scan my code to see if I have done
something incorrectly?  I am outputting my data to a Flash viewer in a HTML
template.

Thank you,

Ryan
