Hi all
I have rigged up a webGIS app (P.Mapper framework) where one of the
underlying datasets is a model grid (many thousand cells) in a shapefile.
The data displays nice and quick when just viewing, but if I allow the user
to select say 5000 cells it is very (extremely) slow to redraw with the
For reference sake:
The issue is also present when using Bing maps as overlay.
I also recompiled mapserver against agg 2.5 and gd-2.0.36RC1, but no change
unfortunately.
As stated in my previous mail, I may have to look for alternatives as the
tilecache will probably not be an option for us.
Hello all,
I'm having difficulties changing mapfile trough url with mapserver 5.6.5.
This is my layer:

How is the selection done? How is the highlighting done? Those processes will
really impact performance depending on how things are implemented.

Tilecache probably is not what you want if you have very dynamic tiles.
Or at least a tile cache that is persistent.
Your problem is with tile edge artifacts. It might be possible to draw
on a slightly larger image than the tile, then cut the tile out of it to
avoid some of those, but there
What's the chance of getting a simple test case to demonstrate the problem?

Hi Wim,
If your data is that dynamic then there is not much advantage in using
tilecache. Perhaps there is not much advantage in making tiled requests either.
Applications asking for 256x256 pixel sized tiles from on-demand bases are
generating rather a lot of load for Mapserver. There is an

The selection of layer data is done by a bounding box, though querying by
parameter values is just as slow. The mapfile is directly calling up the
shapefile (I had just followed the P.Mapper examples of displaying/querying
shapefiles directly). So probably the answers to those questions
My understanding of spatial reference systems(SRS) is that the units of the
utilized by the SRS are inherently part of the definition. When data is
projected to a particular SRS, the units are set by that SRS.
It sounds like you are looking for some sort of cylindrical based SRS

I have a solution to this, a client had exactly the same problem.

Thanks for the suggestions. I am able to reproject my maps with mapserver. I
found out what projection my maps started in by reprojecting in QGIS, it filled
in the starting projection. Either it calculated what that projection was, or
it was the default. Then, wherever my site modified
Yep, it can be done. I'm afraid a how to on your specific problem is
well beyond the scope of an e-mail list response, but if you take the
time to learn MapServer you'll find you can generate the images you
want to embed in your mailings. Based on your website it seems like
doing so would be core
Sorry the link is from a 3rd party provider, not us. I want to make something
internal that does the same thing. Doing a Google search, I find tons on
companies doing this but nothing on how to do it internally. The routing ptp

Jeff,
Here is a high level overview of what you need to do:
You will likely need tools for:
1. geocoding
2. routing
3. mapping
And you will need data to power each of these for the quality and
coverage area that your are interested.
Then you will need to glue these together into an
Hi,
At first I did try with single full page requests to mapserver. However we
do intend to have a fullscreen map available for our customers. Which means
it will at least render 1024*768 png's. That would indicate that
panning/scrolling behaviour will not be fluent, as you have indicated.
We're

I was using this one for 8-bit images, but the anti aliasing was
creating blackish artifacts along the rendered lines. Is there a way to

Hi,
I am trying to connect to a remote wms server from QGIS using https with
basic authentication. QGIS version is 1.5.0-4.3 for x86_64 on opensuse 11.3
(rpm from Application:Geo repo).
I have not been successful using the Layer Add WMS Layer tool in QGIS.
