Re: [mapserver-users] Offset values from database
Would it not be possible to draw the polygon as 2 different polygons (the inner polygon the outer using the postgis functions)? You could specify a fixed offset for one or the other. On the other hand, if you just have 1 polygon (with a single line, so no inner polygons) and you're trying to accomplish a visual effect that the inside of the polygon lies further away, i would accomplish this by drawing a thicker border. Or you could possibly use the asymmetric line drawing functions that are available. Maybe give a more concrete example of what exactly you are trying to do.

Or is the left/right sides of the line strictly relying on the from/to aspects of how the polygon was drawn (clockwise/counterclockwise) This would be handy for off-setting to (ONLY) the inside of a polygon for example.

It must not be the case that at the furthest zoomlevel the lines are further apart. I've looked all over for this, but never really found a proper solution.

Is this possibly a feature for 6.0 ? Are there any other ways how one could offset a feature in pixels, rather than in lat/long coords? Maybe I should elaborate on the original problem a little. Consider 2 line segments that lie above one another. The general idea is to 'offset' them a given x , y value, so they will both display next to one another, rather than on top of eachother. If you would however perform this code simply on lat/long values, it would imply, that when scaling your map at the most detailed zoom level, the lines would lie very far apart, and when zoomed out, they would appear to

Usually, when displaying mapserver data on basemap layers such as openlayers, or directly on google / bing maps, you would use their tiling system.

Re: [mapserver-users] logging GDAL queries
Sebastian, You are using a very small block size, maybe because you are also using ArcGIS products and they only support Oracle GeoRaster with 256x256 blocking. Is that right? Because of that, to access your GeoRaster object, the GDAL driver is requesting a very large array of BLOB (100 approximately). That can make your sever such-up memory from the machine where it is running and it is probably using virtual memory (disk) what is really slow. It also uses some memory on the client side just to hold the array too but if you are running everything (Mapserver,Oracle) on the same machine that will adds up. We are aware of that problem but it would be very helpful if you could file a bug report on GDAL's trac [http://trac.osgeo.org/gdal/] Thanks. Just as curiosity. Did you loaded that image with gdal_translate? How long it took and long does it takes to generate pyramids? Ha, you forgot to say what version of Oracle you are using.

Re: [mapserver-users] Re: logging GDAL queries
Interesting. Why does it need to perform two requires for the same level? I believe that mapserver is doing that. It is running GDALOpen() twice on the same raster/level. In fact it should run that query just once, at the first GDALOpen(), like QuantumGIS does. So for each zoom level it goes through the cursor (array of BLOB) built by that query. But don't be scary of that. It is not loading any raster block in memory at that time. But I understand that by the nature of Mapserver and that GDAL expectation is file reader, that is how it works. It opens and close files several times. Good thing is that at least while GDAL is in memory we can reuse the database connection. It might be part of the solution.

[mapserver-users] Need help tracking down mapserv seg fault
Hello All: Please pardon the very lengthy post. I have attempted to collect as much data as I could think of. Summary: FGS95 with MapServer 5.4.1 on Ubuntu Server, using OGR JOIN results in mapserv seg fault when run from browser, works fine from shp2img. Detailed: I have an FGs95 install on Ubuntu Server 9.10, using MapServer 5.4.1 on the back with a mixed shapefile/PostGIS datastore, GeoMoose 2.2 front-end. Everything is working very nicely except for my current problem. I have a need to color polygons stored in a shapefile, CLASSified based on attributes in an external csv-file. Guidance found in the ether indicates that the only way to do this with MapServer is to use an OGR connection between the shapefile and the csv-file. Using tips found here and there I have been able to construct a SELECT statement in the DATA directive that allows shp2img to create a PNG that looks just like I hoped it would (see attached), but I must confess that I don't fully understand how as the SELECT statement does not look like what I am used to seeing in some proprietary products. I am clearly in need of an OGR education (with lots of example code). The LAYER section in the mapfile is LAYER # Parish Boundary Polygon Outline Layer NAME 'parishes_on_boiladv' CONNECTIONTYPE OGR CONNECTION webmaps_parishes.shp DATA SELECT * FROM webmaps_parishes LEFT JOIN 'bwa.csv'.bwa ON webmaps_parishes.FIPS = bwa.FIPS STATUS default TYPE polygon CLASSITEM PercentageOut CLASS EXPRESSION ([PercentageOut] 0 AND [PercentageOut] = 10) NAME 0 - 10% STYLE COLOR 56 168 0 END END #class (continues with several more classes). The shapefile and csv-file are stored in the same directory. Both have a field FIPS which is the field I wish to join on. The PercentageOut field is in the csv-file. The DATA statement appears to work, but I looks really odd to me. Is there a way to get a table output from the OGR JOIN to study? I have set DEBUG 5 at the MAP level and the LAYER level to troubleshoot, but the process segfaults before any error is written to the ms_error file. The Apache and system logs contain only this when testing from localhost: /opt/fgs/www/logs/error_log: [Thu Aug 12 14:53:02 2010] [error] [client 127.0.1.1] Premature end of script headers: mapserv /var/log/messages: Aug 12 14:53:02 geoview kernel: [12879514.857356] mapserv[24114]: segfault at 0 ip 0945e714 sp bf9058dc error 6 I saw another post with similar issues suggesting it's a library issue, discussing the LD_LIBRARY_PATH environment variable not being set properly for the Apache user. As far as I can tell this variable points to the right place in /opt/fgs/, but to be certain I added a SetEnv/PassEnv statement in the fgs-version of httpd.conf without any change in behavior. In both /opt/fgs/etc/conf/httpd.conf and the local user environment I have LD_LIBRARY_PATH set to /opt/fgs/lib:/opt/fgs/www/lib. Is there a way to see the environment for the Apache user? I don't know how important this is. As mentioned everything else has been and is working very well. Could there be some other conflicting system library picked up? The URL I test with is /cgi-bin/mapserv?map=/opt/fgs/apps/geomoose2/maps/sdwp/boil_adv/webmaps_boil_advisories.mapmode=map and I have confirmed all works fine when pointing the URL to other mapfiles. I set the file and directory permissions to full access to all users temporarily to test and there is no difference in behavior. When I run shp2img on the same mapfile the correct image is returned and there are no errors indicated in the ms_error file. The only oddity I see is in the path used by OGROpen: msLoadMap(): 0.033s msOGRFileOpen(webmaps_parishes.shp)...

Re: [mapserver-users] Offset values from database
I would like to shade the inside of a polygon along it's border. Using the polygon border as the edge. Making wider lines means offsetting the poygon internally or putting up with the edge not being specifically accurate. bobb Wim Vanbelle wimvanbe...@gmail.com wrote: Would it not be possible to draw the polygon as 2 different polygons (the inner polygon the outer using the postgis functions)? You could specify a fixed offset for one or the other. On the other hand, if you just have 1 polygon (with a single line, so no inner polygons) and you're trying to accomplish a visual effect that the inside of the polygon lies further away, i would accomplish this by drawing a thicker border. Or you could possibly use the asymmetric line drawing functions that are available. Maybe give a more concrete example of what exactly you are trying to do.

Is this possibly a feature for 6.0 ? Are there any other ways how one could offset a feature in pixels, rather than in lat/long coords? Maybe I should elaborate on the original problem a little. Consider 2 line segments that lie above one another. The general idea is to 'offset' them a given x , y value, so they will both display next to one another, rather than on top of eachother. If you would however perform this code simply on lat/long values, it would imply, that when scaling your map at the most detailed zoom level, the lines would lie very far apart, and when zoomed out, they would appear to lie on top of eachother.

Sebastian, You said: yep I did... and the weir thing is that generating the images from far away zoom under 12... it performs very well... not sure why it doesn't in the levels 13-17 for that reason I was trying to find the SQL queries But your GeoRaster Pyramid level is maxLevel11/maxLevel By the size of you image you should have 20 level. Can you run sdo_geor.generatePyramid() again changing only the number of levels, keeping the same method. That should run faster, keeping the existing pyramid levels.

[mapserver-users] How to use an ArcGIS geocoding service
I'm building a PHP/MapServer application which needs to perform geocoding. I'm aware that MapServer itself does not geocode. I intend to use a geocoding service hosted on ArcGIS Server. The intent is to have input boxes where the user can enter an address, send this to the geocoding service, and have it return coordinates of the location. Can anyone point me to an example of how to do this with PHP/Mapscript? _ Bob Bistrais, GISP Maine Office of Information Technology ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

You should break your file in 2 files.
Put the session_start function at first and add it to the top of your .phtml
file.
The second file will contain all remaining code.
When using session in pages they have to be sent before any other thing.
This is a requirement in HTTP protocol.
