OK, I've put the following line in my main ka-map html file:
<script type="text/javascript"
src="lib/proj4js/lib/defs/EPSG26919.js"></script>
-and I get the error message (in Firefox/Firebug) the Proj4js is not
defined.

Thanks everyone,
Still not clear on installing the proj4js scripts. I downloaded the zip
file. Where should this be installed to work with Ka-Map? Also, I
don't see my projection def file (EPSG 26919) in there. What parameters
do I need to put in to make my own def file?

You can also re-project the coordinates on the client using Proj4js
(http://trac.osgeo.org/proj4js/).

Hi Mike,
This looks interesting. I'm looking at the user guide, but don't see
where to place it in Ka-Map. Do I include it in one of the .php files?
Or the main html file?

Hi Bob,
I have a similar drop down in our ka-map application that does a zoom to
location. And in our case, the javascript just uses a list of spatial
bookmarks, so no attribute queries are involved at all. This seemed like
it would work fastest, though I never needed to try your way.
Anyhow, if you wanted to try that method I can send you the script.
It's fairly straightforward - just feed in a list of locations and
coordinates, and it builds the list. In your case I guess the coords you
would want to feed it are in lat/long (since that is the display
coordinates of you map now).
As to you original question - my guess is that it is failing because
when the queryByAttributes happens it uses the extent of the found
shape as the "zoom to coords", and since your data is really still in
UTM, it is trying to zoom to UTM coords on a Lat/Long map, which won't
work. To make this approach work you would have to reproject the found
extent on the fly, before allowing the view extent to refresh.
If your drop down list is static and not very long, I think a basic list
of spatial bookmarks will still be quicker.

Subject: [ka-Map-users] queryByAttributes and projection
(Cross-posted to the Mapserver list)...
I have a modified ka-map application with some customized search tools.
One of these tools allows the user to pick a town from a dropdown and
zoom to it. This uses a queryByAttributes process and it was working
well.
The data for the project is projected in UTM in its native format. The
customer asked if we could display the data in lat/long (EPSG:4326). If
I change the projection and extent in the .Map files, the map displays
properly, but the search tools no longer function, I get a "no matching
results" error.
This seems pretty strange, as I am only querying by attributes, not
spatially. So I wouldn't think projection would be an issue. But
apparently it is. Does anyone have some insight as to how I can correct
this (other than reprojecting the data)?

Include proj4js-compressed.js in a script tag in your HTML file. You
probably also want to include projection definition file for your UTM
projection such as:
<script src="lib/defs/EPSG27563.js"></script>
(substitute the correct EPSG file for you map though) The contents of
that file is just the PROJ4 init string as a json object.

hi, Rashad
1. to display the two vectors in one group, you can configure your *.map
file in LAYER section, set GROUP part to be whatever group name you
want.
for example, you want to name your group as 'vectors', so:
LAYER
????? NAME 'vector1'
????? GROUP 'vectors'
.........
.........
and for 'vector2', set in another LAYER section with the same GROUP
name:
LAYER
????? NAME 'vector2'
????? GROUP 'vectors'
.........
.........
then, in ka-map you'll see both vector1 and vector2 are grouped in one
GROUP named 'vectors'.
2. to make the status on and off by default, also you can configure it
in your *.map file in LAYER section, set STATUS to be ON or OFF:
LAYER
????? STATUS ON (or OFF)
.........
.........
if you set STATUS to ON, then the layer will be directly displayed on
ka-map activation
hope it helps...? :)
