AW: [mapserver-users] visualisation of image with overviews
Hi Toni, I think gdal_translate is not able to save overviews once you produced them with gdaladdo before. Therefore you do have to use gdaladdo after you are done with all the other stuff. But as far as I know you can't do both: Use Internal Tiling and overviews, because gdaladdo does not support the creation option for internal tiling. I don't know what gdal_translate does with the internal overviews once they are created, maybe the one with the lowest resolution is saved. ;-) I did a lot of downsampling aerial images using gdalwarp with -rc. for creating 'external overviews'. This way I did always get very good results and I can use internal tiling too. For the mapfile I calculate proper scales depending on input image resolution and the resolution of the presentation (e.g. max scale = 20cm/dot input image x 28 dpc (72dpi) /or 38 dpc (96dpi). For sure in any case of resampling arial images you do need 24bit images. This might cause more effort, but in my opinion the results are good and fast.

The different overviews look really poor zooming in the map. What i tried until now is, resampling the original image with gdal_addo (gdaladdo -r nearest , gdaladdo -r average_mp, gdaladdo -r average_magphase, gdaladdo -r mode) and i also made an gdal_translate (gdal_translate -of GTiff -co TILLED=YES), but the results did not look even better. Any one an suggestion how to handle the orginalimage?

Hi Jukka, I tried another getFeature request using your syntax. I only replaced the 'EPSG:4326' to 'EPSG:25832' since the coordinates are in this reference system. Unfortunately I got the same result. It doesn't matter if I ask for VERSION=1.1.0 or VERSION=1.0.0 - I tried out both.

[mapserver-users] Filter Encoding with Spatial Filter within WFS-Request
Dear MapServer-User, I configured MapServer version 5.6.5 as WMS- and WFS-Server to offer information about land and properties. I use PostgreSQL/PostGIS (8.4.4/1.5.1) as datastore in this case. The spatial reference system is EPSG:25832 und the type of the geometry is MULTIPOLYGON. OS is Suse Linux Enterprise Server 11, Servicepack1. WMS and WFS work fine until I use a spatial filter within the getFeature-Request of the WFS. In this case the response doesn't deliver any features. Nevertheless the number of features (e.g. numberOf Features='4') is correct. I tried this out with a couple of different boundingboxes and the known number of features that intersect these boundigboxes. In all cases I do not get any features back, but always the right number. So it seems that at least the intersection of the boundingbox and my data works correctly. Please take a look at the following request and response that illustrate that problem: Request: http://myserver/cgi-bin/mapserv?map=/mapserver/mapfiles/u218768/ku_testwfs.mapREQUEST=getFeaturetypename=folie001SERVICE=WFSVERSION=1.1.0; Filter=ogc:Filter Intersects ogc:PropertyNamemsGeometry/ogc:PropertyName gml:Polygon srsName='EPSG:25832' gml:outerBoundaryIs gml:LinearRing gml:coordinates409350,5709890 409350,5709910 409370,5709910 409370,5709890 409350,5709890/gml:coordinates /gml:LinearRing /gml:outerBoundaryIs /gml:Polygon /Intersects /ogc:Filter Response ?xml version=1.0 encoding=ISO-8859-1 ? wfs:FeatureCollection xmlns:ms=http://mapserver.gis.umn.edu/mapserver; xmlns:gml=http://www.opengis.net/gml; xmlns:wfs=http://www.opengis.net/wfs xmlns:ogc=http://www.opengis.net/ogc; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xsi:schemaLocation=http://mapserver.gis.umn.edu/mapserver http://myserver/cgi-bin/mapserv?map=/mapserver/mapfiles/u218768/ku_testwfs.mapSERVICE=WFSVERSION=1.1.0REQUEST=DescribeFeatureTypeTYPENAME=folie001OUTPUTFORMAT=text/xml; subtype=gml/3.1.1 http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd; numberOfFeatures=4 gml:boundedBy gml:Envelope srsName=EPSG:25832 gml:lowerCorner-1.00 -1.00/gml:lowerCorner gml:upperCorner-1.00 -1.00/gml:upperCorner /gml:Envelope /gml:boundedBy /wfs:FeatureCollection Indeed of this behavior the WFS returns features when I do not use a spatial filter.
