You can check this with psql: select proj4text from spatial_ref_sys where srid=2393; The result should be close to +proj=tmerc +lat_0=0 +lon_0=27 +k=1.00 +x_0=350 +y_0=0 +ellps=intl +towgs84=-90.7,-106.1,-119.2,4.09,0.218,-1.05,1.37 +units=m +no_defs If it is not, update the record. A related thing is that Mapserver epsg text file often comes without towgs84 parameters for the Finnish KKJ zones. This is what I seem to have on this computer: KKJ / Finland Uniform Coordinate System 2393 +proj=tmerc +lat_0=0 +lon_0=27 +k=1 +x_0=350 +y_0=0 +ellps=intl +towgs84=-96.0617,-82.4278,-121.743,4.80107,0.34543,-1.37646,1.4964 +units=m +no_defs You can see that the parameters are not the same. There are more parameter sets around and that's actually the reason why Proj4 comes or at least used to come without any parameters because none of the sets was authorized. The results of these transformations are rather close and accurate to about one meter. You can read also http://latuviitta.org/documents/YKJ-TM35FIN_muunnos_ogr2ogr_cs2cs.txt (in Finnish, I suppose it is not a problem for you). -Jukka Rahkonen- Pena Kupen wrote: Hello all, Last time I was successfully helped by Ralf - Thank's once more time! http://postgis.refractions.net/pipermail/postgis-users/2011-March/029055.html Now I have same type of problem, but I cannot get correct result.

Re: [mapserver-users] Heatmap / choropleth from points
Hi Daniel, So if I undestand correctly you want to display you points and the colour the areas around them according to the nearest point (1), or if possible make a continous interpolated map that shows the gradients (2)? OK, this is not in the MapServer-topic, because MapServer has no way to do this. So I suggest we move this conversation private, but I'll try to give you an answer for future reference. If you have any questions, mail me directly. If this is indeed as you say non-dynamic, things are easy; with any respectable GIS package, you can create option (1) by making a Voronoi diagram. This makes polygons around yout points in which every location in its interior of the polygon is closer to its center point than it is to other points. The result is a vector image (shapefile). To create option (2) you have to interpolate these points into a (continuous) raster through any interpolation method. Simplest is nearest neighbour which in essence creates a Voronoi Diagram in raster format. If you want to go more pro, there is Inverse Distance Weighted (which I do not encourage people using because the options have huge influence on the outcome and are note really exact). Then there is Kriging, but you need to be into statistics quite a bit to be able to get a good outcome -- if not, leave it alone. Then there is also Natural Neighbour interpolation, which uses a Voronoi Diagram as its basis, and is thus quite well suited for using points that are anisotropically distributed, and when kriging is not an option. If you do want these things programatically, there are a couple of python scripts I have that you could use for create Nearest Neighbour and Natural Neighbour interpolations. You will need to adjust those quite a bit.

[mapserver-users] RE: polygon tool
Hi Bob, You could also try using Fusion, it also has a polygon tool in there, but again its based on Open Layers. I gues you can make your own, but you'd need some sort of framework that converts the drawn polygon to the location, projection and units that your basemap is in, for which openLayers is the perfect framework I think.

[mapserver-users] Re: GetFeatureInfo request in UTF8-environment
Hi, I had a similar issue, and the solution I used works but is labour intensive. I'm working mobile right now so I can't send you the link, but the solution is on the Esri forum somewhere. It concerns setting a registry key to a certain value. After this, restart ArcGIS (assuming you have this) add the shapefile, and then export it by rightclicking it in the table of contents- export data. Save it as a different file, and the attribute data will be in UTF8. I'll see if I have the link somewhere tonight.

The shapfiles are created/updated in an Windows-environment by several, external contributors. Hence they are encoded in Wiindows-ANSI (cp: 1252). If i do an GetFeatureInfo-Request on the attibutes of the shapefiles all special characters (umlauts) are garbled. This is no wonder since the content of the shapefile-attributes must be recoded to utf-8 prior to insertion in the template.html. How can this be acomplished?

Again thanks for your reply; I've been abroad for a month and

This behaviour follows the edges of the areas perfectly. Also I
checked it out with fixed coord pairs, and it doesn't seem te related

Tom,
I agree with Alexander that you should be carefully reviewing your
input coordinate and insuring it is in the same coordinate system
as the raster file. The returned values are expected if you are
attempting to fetch a non-existant result shape.
If you simplify your test case down as much as you can and you still
can't figure out why you do not get a result then you could try to
bundle this up and submit it as a ticket. Keep in mind that such a
ticket is much more likely to be acted on if you make it *easy* for
the developer to reproduce your problem.
Best regards,

*** For the querying script I use this:
$szLayer =mask;
$oLayer = $oMap-getLayerByName($szLayer); //getLayer
$oMap-prepareQuery();
// To be sure no CRS problems arise,I use these coords, smack in
the middle of the left area
$x = 360429;
$y= 642536;
/*
//For NoData, use
$x = 759753;
$y = 935658;
// for a point rightbetween the 2 areas
*/
$oPoint = ms_newPointObj();//Create Point
$oPoint-setXY($x,$y);
$status =$oLayer-queryByPoint($oPoint, MS_MULTIPLE, 1); //Query
$status =$oLayer-open();
$result = $oLayer-getResult(0); //GetResult
$numResults = $oLayer-getNumResults();
$shape =
$oLayer-getShape($result-shapeindex,$result-tileindex); //
Retrieve shape
echo(var2json($shape)); //echo to browser
Cananybody confirm that they get the samebehaviour?
Cheers,
Tom

This results in the follwing json code to be returned:

RE: [mapserver-users] Mapscript Rasterquery returns empty result
Hi Frank, Alexander, Thx for the replies. I'll give it a try as soon as possible. I do have a good hunch however that it won't come down to the coordinates, because when I try his on a tiff, this is the error it gives when clicking on a section of the tiff that has any value except noData; when I click on an empty section (NoData) it gives a different error. Some testing with this showed that it does send and uses the correct coords. I think it might have something to do with the tiffs themselves. I'll follow your advise an create a testcase as simple as possible. Note that I'm using 5.2.1 and can't easily upgrade to 5.6, so a ticket might not be appropriate?

[mapserver-users] Mapscript Rasterquery returns empty result
Hi,
I have the following code:
$oMap-prepareQuery();
$oPoint = ms_newPointObj();
$oPoint-setXY($x,$y); //coords received from a AJAX call
$oLayer = $oMap-GetLayerByName($szLayer); //Name received from a
AJAX call
$status = $oLayer-queryByPoint($oPoint, MS_MULTIPLE, 1);
$status = $oLayer-open();
$result = $oLayer-getResult(0);
$numResults = $oLayer-getNumResults();
$shape = $oLayer-getShape($result-shapeindex,$result-tileindex);
echo(var2json($shape));
This results in the follwing json code to be returned:
{_handle_:Resource id #45,numlines:1,type:0,index:-1,
tileindex:-1,classindex:0,numvalues:8,text:,
bounds:{_handle_:Resource id #46,minx:607000,
miny:677000,maxx:607000,maxy:677000},
values:[null,null,null,null,null,null,null,null]}
No matter what I try, it keeps returning empty shapes. How can this
be?
P.S. I'm using mapserver 5.2.1 from the ms4w package.
Cheers,
Tom
