[mapserver-users] size of legend icon for pixmap-type classes
Hello all, I'm trying to make mapfile which includes polygon layer with pixmap-type symbol classes. The symbols are defined like ... - SYMBOL NAME symbol1 TYPE pixmap image /somewhere/symbol1.gif transparent 1 END - The polygon layer with pixmap is drawn perfectly by map mode, however in legend mode (mode=legend), the icons drawn like line layer. How do I say... it seems that mapserver draws icon for line ( /\/ ) like ArcMap's line layer using brush of the gif image. I defined the layer certainly as type polygon. - layer name jimon connectiontype postgis connection user=db password=xxx dbname=DB host=localhost port=5432 data the_geom from polygon status on type polygon classitem id projection init=epsg:4326 end class name pattern1 expression 1 style symbol symbol1 end end end - What I want is normal rectangle-shaped icons filled up with the gif. Could anyone help me ? Thanks, Isao NASUNO ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] MULTIPOINT and POINT in same geometry column
Hello all, Is there any way to append 'MULTIPOINT' shape files and 'POINT' shape files into same table with a geometry column ? I guess the geometry column should be 'MULTIPOINT' geometry-type, and the 'POINT' shape should be translated 'MULTIPOINT' (but only one point in one record)in the appending process. Any suggestions ? I'm using - PostgreSQL 8.0.3 - PostGIS 1.1.3 - Mapserver 4.10 Thanks, Isao Nasuno ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] MULTIPOINT and POINT in same geometry column
Hi Subha, So easy ! I'll try it. Thanks for your quick response.

Re: VS: [mapserver-users] Converting datum using ogr2ogr
Hi Jukka, and List, I got to the conversion that I expect with your advice. Now I understand how to use it. Many thanks ! Isao Rahkonen Jukka wrote: Hi Isao, I am sorry, I must admit that I haven't done my homework with datum shifting. However, I believe that reason for not getting any change in your reprojection is because the definition in the FWTools epsg ligrary for epsg:4301 is this: # Tokyo 4301 +proj=longlat +ellps=bessel +no_defs So it gives no towgs parameters which would tell what kind of shifting should be done. For comparison, this projection using bessel does have towgs84 parameters and a trial with that should lead to different result: # Bukit Rimpah 4219 +proj=longlat +ellps=bessel +towgs84=-384,664,-48,0,0,0,0 +no_defs If you can find somewhere the towgs84 parameters and insert them to your source projection you may get what you want. It is not necessary to edit the epsg text file but even better to give the projection directly for ogr2ogr this way: ogr2ogr -s_srs +proj=longlat +ellps=bessel +towgs84=-384,664,-48,0,0,0,0 +no_defs -t_srs epsg:4326 Of course with your correct towgs84 parameters. This way it is simple to play with adjusting the parameters, and most important, you know for sure what parameters ogr2ogr is going to use. It is possible that right parameters for you are TOWGS84=-148,507,685,0,0,0,0 but I can't be sure. It was just the first hit from altavista search. -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Puolesta NASUNO Isao Lähetetty: 15. toukokuuta 2008 7:59 Vastaanottaja: Rahkonen Jukka Kopio: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] Converting datum using ogr2ogr Hi Jukka, Thank you for your response. yes, I tried with the options (s/t_srs), however it makes conversion for projection but not for datum. In my case, I used following options but the input and output are exactly same. -s_srs EPSG:4301 -t_srs EPSG:4326 (GCS with bessel)(GCS with WGS84) I checked GDAL FAQ and found following. http://trac.osgeo.org/gdal/wiki/FAQCoordinateSystemsAndProject ions#WhydoesntGDALautomaticallychoosethedatumtransformation Why doesn't GDAL automatically choose the datum transformation? There is no such thing as an accurate default set of datum transformation parameters for a datum. OGR uses (NADCON) by default, which is the most accurate available for North America, but in the general case (worldwide) this is very hard to determine and there normally is no such thing as a default. The transformation that should be used depends on the exact area covered, accuracy required etc. In other words, user beware and do your homework. Is this the reason ? I am not sure if ogr2ogr can accept the parameters in manual. Please help if any idea.
