[Cartoweb-users] problem with PROJECTION in mapfile

Milo,
Did you check that your EPSG code actually exists in the proj file (in
proj/nad/epsg)? For geographic projection you would find this line:
# WGS 84
<4326> +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs no_defs <>
Also check whether you used capital letters for the EPSG code anywhere in
your map file ( I had that problem once... and its case sensitive).
You could also check
1.)
what the result are - if you set the map projection of the whole map to
PROJECTION
"init=epsg:4326"
END
2.)
Does the layer work if you skip the EPSG code but define its projection
manually in the map file (replace "init=epsg:4326") with:
PROJECTION
"proj=longlat"
"ellps=WGS84"
"datum=WGS84"
END
Karsten

I dont have a solution for this problem, but I think it is weird a
projection change would have effect on the way mapserver handle expression.
what's your whole layer definition ?

Oliver

Subject: [Cartoweb-users] problem with PROJECTION in mapfile
Hello list,
I have a mapfile with layers in different projections. When I try to set a
projection within a LAYER in the mapfile like this:
PROJECTION
"init=epsg:4326"
END
I get: Error in msEvalExpression(): Cannot evaluate expression, no item
index defined.
But when I set it to:
PROJECTION
"init=epsg:28992"
END
which is the same as the map projection, everything goes right, but my
layer shows up at the wrong position.
My gut feeling tells me that something is wrong with my EPSG codes. What
can be the trick?

Did you modify the exportPfd.ini ?

3DSitewindows seems to screw the icon path generation.
you could touch up the layers.tpl and test if you are out of range (meaning
the nap and nam icon would be displayed) by checking the values of the
$element.nextscale or $element.layerOutRange parameter (in the template) and
set the path directly.
something like:
<img src="{if $element.layerOutRange > 0}/some/path/to/nap.png{else if
$element.layerOutRange <
0}/some/path/to/nam.png{else}$element.layerIcon}{/if}" alt="" class="pic"
...

Oliver

Carolin,
thank you for the response. You set me on the right track!
I discovered that the URL that is created pointing to the nap.png is
relative to the website root. Since my cartoweb3/htdocs is not at the root
of the website, it fails to find the nap.png
I solved this by creating a virtual directory in IIS (my webserver of
choice) that points to the gfx directory for the virtual name
http://myserver/gfx/
I do however think that this will be a hassle when copying projects (what
I do a lot) so it would be better if this is recognized as an issue and
fixed.

Hi Milo,
we had the same problem... there should be an icon called nap.png
instead of your layer icon, when it is invisible. I'm not sure how we
solved it... I think, we created a new folder called icons in
<project>/server_conf/<project> and created this png here... Maybe,
you'll find nap.png somewhere else in the cartoweb folder, then you have
to copy it in this newly created icons folder.
As I said, I'm not 100% sure (somebody else fixed this in our project),
but it should be something like this
Bye

Hello list,
Somehow, no matter what I do to the particular layer "Buurtgrenzen" I
get no legend icon.
Please find my test environment at:
http://cartoweb.bosqom.nl/cartoweb3/htdocs/webGIS.php
Can anyone tell me why there is a redcross in the legend?
