[Chameleon] adding my own data to chameleon.map file

[Ken Sanderson]

The data with the samples doesnt have attached projection information,
but if you look at the map file itself it has a set projection of "NAD83
LCC for Canada" as indicated by the line: init=epsg:42304. I just looked
up 42304 in the EPSG file in your Proj folder. Since the other layers
dont have projection information I assume they are all the same
projection of the map file.
 
I am realitively new to the whole mapserver thing as well, but I think
if you just create projection information for your layers, specifiying
the projection they are actually in, they will get projected on the fly
to appear appropriately with the other layers. Alternately you could use
the projection information found in the EPSG file to reproject your
layers on your end so they automatically match up with the ones already
there.
 
I really recommend the MapLab product for making your MAP files, adding
new layers, etc. Saves a lot of effort and it has a built in preview
tool. When I started messing with my own layer I just started from
scratch with my own MAP file and added a layer a time, messing with
things till I understood them.
 
Hope that helps
 
Ken

Hello,

 

I am a newbie so please bear with me.

 

I have successfully installed the ms4w package with chameleon 1.99 beta,
all the chameleon sample applications work fine.  I am now attempting to
add some of my own data to the chameleon/samples/map/chameleon.map file.
I've added a shapefile and a geotiff to the samples/data folder and
added them as layers to the chameleon.map file.  When I run one of the
Chameleon Sample Applications the new layers appear in the legend but
they are a no-show on the map.  

 

With regards to the shapefiles, I'm thinking they are in a different
projection.  How can I reproject to the same projection as the sample
data?

 

With regards to the geotiff, I'm not sure.  Maybe I need to reproject it
as well.  

 

I've also tried using a jpeg with a world file but.no-show on the map.

 

Maybe I'm adding the layers wrong?  I've attached my chameleon.map file
and marked the new layers with a line of ####.  Any help would be
greatly appreciated.  Thanks in advance.

 

Jason
