Re: [mapserver-users] mapserver 5.4.2 Reprojection error

[Rahkonen Jukka]

Hi,

I believe it is basically this issue:
http://trac.osgeo.org/proj/ticket/11

So it is known already.  Make a comment on a ticket and add some pressure, 
perhaps some day it will be corrected.

It seems to work with both  EPGS:31467 and EPGS:32632, thanks again.
Is it a bug in Mapserver, it isn't ? should I report a bug?

greets,
Tom

Hi,

I am not sure if this helps in your case, but you can try to edit the "epsg" 
file in the projection library and add +towgs84=0,0,0 in the line that defines 
the <31467> projection.  EPSG:3067 needs this extra parameter for sure and I 
believe it is the same with your next try with  EPGS:32632. Let's hope it cures 
31467 as well.

Hallo list,


With mapserver 5.4.2 (FGS API 9.5) , if my map is reprojected in 
EPGS:31467, it is shifted about 100 m to north and 50 m to east (approximately).
The same data with the same mapfile and the same URL works fine on 
mapserver 5.0.2 (FGS API 1.0.0).
The data are stored in an Postgis Database with srid 4326.
The URL I'm using is:

http://localhost:8081/cgi-bin/map?request=getMap&version=1.1.1&srs=EPSG:31467&bgcolor=00&transparent=true&exception=application/vnd.ogc.se_inimage&layers=messe_background,halls&width=1600&height=1600&bbox=3553126.5489076,5796728.52646645,3556663.71956136,5800882.49936431&format=agg
 

 


On the linked picture you can see the same map with the same bbox 
generated by the two version of mapserver. The map on the right is to 
north-east shifted, the map on the left is ok.

If the map is not reprojected (EPGS:4326) there are not errors.


Did somebody observe the same issue?

Thanks,
Tom
