[mapserver-users] Re: mapserver documentation: unique gid using srid=x ?
Hi, according Mapserver docs: http://mapserver.org/input/vector/postgis.html there is different syntax of using USING UNIQUE gid USING SRID=x string in DATA line in similar cases. In simple case example: DATA the_geom from the_database USING unique gid using srid=4326 In case of using a SQL subquery example: DATA the_geom from (select g.gid, g.the_geom, a.attr1, a.attr2 from geotable g join attrtable a on g.gid = a.aid) as subquery unique gid using srid=4326 When comparing these two examples, second example (SQL subquery example) is missing first USING keyword. Shouldn't be second example as following: DATA the_geom from (select g.gid, g.the_geom, a.attr1, a.attr2 from geotable g join attrtable a on g.gid = a.aid) as subquery USING unique gid using srid=4326 When testing on Mapserver 5.2.x, it seems to be typo in documentation. If I am correct, would You please fix it ? Thanks.

[mapserver-users] many raster projections
Ok, I'm confused. Most of the problem is probably because I'm a programmer, not a mapper. I have arial imagery of Minnesota, multiple sets, each seeming to be in a different projection. At the top of my mapfile I have this: MAP EXTENT 1285920 1377857 1426390 1506589 PROJECTION +proj=tmerc +lat_0=35.84 +lon_0=-92.5 +k=0.3 +x_0=50 +y_0=0 +ellps=GRS80 +units=m +no_defs END There are no other PROJECTION settings. Most of the images seem to work. I got the projtext above from loading one of the shapefiles into qgis and looking at its properties. I just kinda hoped they'd all be the same. I did try adding a PROJECTION to the raster layer, but it didnt seem to work. So I thought I'd just re-project the imagery. Three sets of imagery seem to work (I didnt touch them, they always worked), they have (again copied from qgis) proj text's of: +proj=tmerc +lat_0=35.84 +lon_0=-92.5 +k=0.3 +x_0=50.01 +y_0=0 +ellps=GRS80 +datum=NAD83 +to_meter=0.3048006096012192 +no_defs +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs and +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs One set is displayed way off the map, way far away from where its supposed to be.

RE: [mapserver-users] Re: Making labels appear less often on adjacent tiles
Sounds like you might want to use the MINDISTANCE label parameter in this case. I think if you see it to a value close to the size of your metatiles you'd get sparse labeling of those features but not simply the single label that pre-clipping computation gives you. That's the approach I take with things like National Forests in Minnesota where 1 polygon covers ~3 million acres...

RE: [mapserver-users] many raster projections
Andy, It looks like you have data in at least two or three different projections. If you want to display them in the same map using MapServer, you need: - a projection block at the MAP level. This defines your output projection. The map UNITS and EXTENT need tobe consistent with this projection. - a projection block for each layer. This is used to tell MapServer what projection the data for that layer is currently in. MapServer then uses this info to warp all of the layers into the same output projection. Does this help?

Re: [mapserver-users] many raster projections
Thank you, but that didnt seem to help.
I left the main PROJECTION as is, and I changed my raster to this:
LAYER
NAME raster07
STATUS off
TILEINDEX raster07.shp
TILEITEM location
TYPE RASTER
PROJECTION
+proj=utm +zone=15 +ellps=GRS80 +datum=NAD83 +units=m +no_defs
END
END
Now, here's another problem (to add to the layers of projections). I'm
using OpenLayers on the front end (for the website), and I have no idea
what all this projection stuff means, and wasnt sure how to set it in
OpenLayers.
I create the map like this:
map = new OpenLayers.Map(map, {
controls: [
new OpenLayers.Control.Navigation( {zoomWheelEnabled: false} ),
new OpenLayers.Control.PanZoomBar(),
ls
],
numZoomLevels: 12,
maxExtent: new OpenLayers.Bounds([%minx%], [%miny%], [%maxx%],
[%maxy%]),
maxResolution: 250,
unit: 'm',
projection: EPSG:2816}
);
It seems to work. I totally guessed at EPSG:2816, I have no idea if it
matches:
+proj=tmerc +lat_0=35.84 +lon_0=-92.5 +k=0.3
+x_0=50 +y_0=0 +ellps=GRS80 +units=m +no_defs
The shapefiles show up, as do most of the arials.
Are these all publicly available datasets?
I dont know, they are from the Livingston county Missouri Assessors
office. Hum... did I say Minnesota before? That was wrong, its MO not
MN. Its about 2 gig, and I could email and ask them if it really comes
down to it.

Re: [mapserver-users] many raster projections
To take OpenLayers out of the equation, I made myself a test.map file
that just included two layers and used shp2img.
If I switch on the 2007 (raster07) then I get no arial (the result image
is just a gray slate).
If I switch on raster09_chil, the result image has the arial's as expected.
Hopefully the attachment will make it through.

Andy, To be more specific: I am using GeoMoose. GeoMoose draws each layer separately so we do benefit by having a multi-core processor even if there is only one user. We also are using a WMS Service so air photos is for the most part a non issue. If my understanding is correct hyper-threading has up to a 20 percent increase in speed. However, the performance increase is highly application specific and in some cases performance may actually be lower with Hyper-Threading enabled.

If your system is cpu bound then I'd bet the difference between enabled and disabled is minimal (regardless if the difference is faster or slower). 20% either way is not very much. If your not cpu bound, I'd bet you see no difference at all. Of course, these are hugely big guesses. And probably wrong. I dont have any numbers to share. Sorry. -Andy On 2/8/2010 2:48 PM, Mark Volz wrote: Andy, To be more specific: I am using GeoMoose. GeoMoose draws each layer separately so we do benefit by having a multi-core processor even if there is only one user. We also are using a WMS Service so air photos is for the most part a non issue. If my understanding is correct hyper-threading has up to a 20 percent increase in speed. However, the performance increase is highly application specific and in some cases performance may actually be lower with Hyper-Threading enabled.

If so how much? Mark Volz GIS Specialist Lyon County, MN Hey Mark, What sort of usage are we talking? Web hosting? Shapefiles and arials? I'm not sure if mapserver itself will use mult-threads, but if you have multiple requests comming into a website, apache/cgi/mapserver/etc will use multi process/threads/etc. Its tough to say the performance increase. I'm host several maps on a dual-core box, and the cpu's sit around 2 percent. And with lots of arial imagery you might hit disk io limit before you hit cpu limit. (However, I have had some mrsid files that were really cpu intensive to uncompress, they were cpu bound). Are your cpu's even pegged? So, I guess, the answer is, it really depends on a lot of different variables. -Andy ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
RE: [mapserver-users] php mapscript loadQuery problem
The way loadQuery works is like so: 1) Load the queryfile into an internal queryObj 2) Execute the query defined by the queryObj If an error occurs at step 1 you'll get a load error of some sort. If at 2 it is deeper inside one of the query methods. I'm not a PHP user but in Perl you can access the msGetErrorString() function like so: print mapscript::msGetErrorString(\n); This will print the entire error stack one per line. PHP-MapScript must have something similar. We need to know if the problem is parsing the query file or if it's running the query itself.

Where would I look for the errors that the query file parser throws? I don't see any in the error_log for apache, which is where all my php errors are logged. Does that mean that the parser is having no problems parsing the file, but something else goes awry? I added some information hoping it may help. This is my command from php $test = $map-saveQuery(/tmp/testfile.txt); error_log($test. .MS_SUCCESS); The output from the error_log line above is Testing save query: 0 0 I then try to load the query file with the following commands. $test = $map-loadQuery(/tmp/testfile.txt); error_log(Testing load = .$test. - .MS_SUCCESS); The output from the error_log line above is Testing load = 1 - 0 Thanks, Paul On Feb 1, 2010, at 3:55 PM, Lime, Steve D (DNR) wrote: I'll send you more details when I get time tonite (I hope) and can test things. I've been using 5.6 save/load query functions a ton via the CGI but not PHP. I tested a bunch with Perl MapScript and will have to check those methods against what PHP is doing. Here's what the lines mean: Line - Contents 0 - magic string 1 - mode, type (single or multiple), qlayer, slayer 2 - point x, point y, buffer, max results (queryByPoint) 3 - query rect (minx, miny, maxx, maxy) (queryByRect) 4 - shp index, tile index, clear cache flag (queryByIndex) 5 - qitem or NULL (queryByAttribute) 6 - qstring or NULL 7 - operator (used by WFS) 8+ - query shape (queryByShape) Basically each line or so after the first couple match a MapServer query method and it's parameters. The file contents look fine to me. The query file parser will throw a detailed error message if it has a parsing problem.
