[mapserver-users] Ozz
Hi Everyone, Can someone explain me functions of the mapcache? Is it making my map fast or is it for another purpose. I read a lot about it I couldn't understand. what is the main work that mapcache does? Thanks!! ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] Scripted geoprocessing
I am looking for a way for this script to dissolve polygons with a common attribute. This will help rendering speed and ease of visualization. What are you trying to achieve? Splitting a shapefile into smaller pieces by grouping features with common attribute(s) as a kind of pre-classification? Then ogr2ogr might help you. See http://www.gdal.org/ogr2ogr.html and http://www.gdal.org/ogr/ogr_sql.html how to use this tool. Also http://mapserver.org/optimization/vector.html might help you.

[mapserver-users] Positioning of point symbols
I am using mapserver 5.6.7 and it appears that when using a pixmap symbol to represent a point geometry on the map, the image is placed with its center on the point. Is there a way to adjust the image so its bottom center is placed on the point instead? Thank you, Jason ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] Positioning of point symbols
Hi Jason, perhaps the offset parameter can help?

I read a lot about it I couldn't understand. what is the main work that mapcache does? Mapcache is a proxy between mapserver or other services and you client. It takes the clients requests for tiles and gets them from the backend services and stores them in a cache then gives them to your client. If the requested tile is already in the cache then it just serves that. So by using potentially a lot of disk space to save tiles in it avoids excessive drawing of the same tiles multiple times by the backend. This is basically how Google does it and why Google is so fast. mapserver mapcache - browser client | | GIS data tiles If mapcache has the tile it servers it. If mapcache doesnot have the tile it gets it from mapserver. Serving tiles is fast, drawing tiles/images is slow. Mapcache can do some other tricks like compositing a larger image from a bunch of tiles to server WMS request faster also. -Steve W ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Re: [mapserver-users] GetStyles SLD does not include Opacity value
Now that I've advanced beyond the simple example included above, I see a possible shortcoming with the current implementation of the GetStyles request with respect to including rule's opacity and am wondering if this is something worth pursuing... While it is easy in my original example with a single CLASS in the layer, to move the opacity parameter within the CLASS' STYLE, what if my LAYER has a number of CLASSes? Given the current implementation, if I want to see the opacity in the GetStyles response, I will have to include the OPACITY setting in every CLASS STYLE, even though they are all the same and a major advantage of the LAYER's OPACITY value is avoiding that duplication (and potential for inconsistency). Since the GetMap and GetLegendGraphic renderers are capable of reviewing whether a CLASS STYLE's or the LAYER's OPACITY value is set and draw the image accordingly, it must be possible for the GetStyles response to do the same. My question is Should it? Or am I off the mark in my expectations here?

[mapserver-users] Mapserver/PostGIS Faster Initial Load Time
Basically my mapping setup is, from client to server, Openlayers WMS/WFS (Internet Explorer on XP Pro SP3) - Mapserver CGI - Shapefile (Tiffs) or PostGIS (XP Pro SP3 - IIS FastCGI). From boot up, the initial, or first load of maps, takes up to 15 seconds. After that, it flies along fine. I've tried pre-loading in a hidden browser instance but that didn't work. I cannot get that initial load time down at all. Any tips to reduce the time taken for the first load of the software: Specifically Mapserver whether it's creating the map from PostGIS or the shapefile (Tiffs). Many thanks.

[mapserver-users] MapServer with Geodatabases
This is a just wondering question- Has anyone used MapServer with ESRI Geodatabases as a data source? In particular, I was wondering about file geodatabases? Honestly, I don't have plans to do this myself, but I am preparing a presentation on Open Source web mapping, and I'm sure this question will come up. So, if anyone has used a GDB with MapServer, I'd appreciated any feedback, good or bad, describing your experiences. Thanks, Bob ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] MapServer with Geodatabases
I've used MapServer via/OGR with the newish File GeoDatabase format and it does work. It's just markedly slower than using straight shapefiles and/or PostGIS.

Hi everyone,
I am trying to put an icon on my map by using text marker. But it doesn't work.
There is one marker that is working very well from the instructor. When I try
to create my own it is not working or it is not showing my icon it is showing
red icon which is from open layers. Could you please Help me about this issue?
Also Thank you Stephen Woodbridgefor your explanation of the mapcache. It was
helpful.

Re: [mapserver-users] Hi All
Hi Özgür,
Sorry but this question is OpenLayers so you need to post it on that
list. I have cc'd it there.
