Re: [mapserver-users] maps all look squished
Hi, What is the projection of your layer data, what is the projection for the output, and how do you request the image from Mapserver? -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: Josh Jordan Lähetetty: pe 20.8.2010 6:16 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: [mapserver-users] maps all look squished No matter what projection I use, my maps always look stretched too wide, or squished.

Re: [mapserver-users] maps all look squished
The projection in the mapfile is init=epsg:2023. This is the same projection between /MAP/,/END/ as it is for all the projections between /LAYER/,/END/. When the projection of a layer is not the same as the projection of the map, the layer does not print. It seems redundant to have to write the same projection everywhere.

Re: [mapserver-users] maps all look squished
Hi, I have never used any MabObj things, only shp2img, Mapserver CGI and WMS clients. However, I guess that your system is taking the EXTENTS from your mapfile as well as SIZE. If you change the output projection without changing extents you will see nothing because the view window is no more in the same place as the data are. And SIZE parameters can squeese your image, play with them and see. -Jukka- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: Josh Jordan Lähetetty: pe 20.8.2010 17:24 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] maps all look squished The projection in the mapfile is init=epsg:2023.

Re: [mapserver-users] maps all look squished
When I change the extents, it will always zoom out so it can fit everything in the extent in the window. So if I change the extent to be only a thin vertical line it makes no difference. Changing the size makes no difference, it was 500 600, I changed it to 100 5000 and 5000 100 and there is no difference. --- On Fri, 8/20/10, Rahkonen Jukka jukka.rahko...@mmmtike.fi wrote: From: Rahkonen Jukka jukka.rahko...@mmmtike.fi Subject: Re: [mapserver-users] maps all look squished To: Josh Jordan outerspacema...@yahoo.com, mapserver-users@lists.osgeo.org Date: Friday, August 20, 2010, 11:22 AM Hi, I have never used any MabObj things, only shp2img, Mapserver CGI and WMS clients.

Re: [mapserver-users] maps all look squished
Hi, I am pretty sure that it is a projection problem. Open your shapefiles with some GIS program like QGis or OpenJUMP and you will see that they look the same as your Mapserver output. If you want the output look different you must set Mapserver to reproject the data. It is possible only if you can tell in the mapfile correctly what is the projection of the input data. If your shapefiles are missing the .prj files it is best to ask about the projection from the one one who has created the data. Changing the projection parameter in both the input and output does not have any effect because then Mapserver just allways sees that input and output are the same and therefore there is nothing to do, just push the raw data ahead. -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: Josh Jordan Lähetetty: pe 20.8.2010 18:37 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] maps all look squished When I change the extents, it will always zoom out so it can fit everything in the extent in the window.

RE: [mapserver-users] maps all look squished
I'm wondering how the maps are being displayed. The original sample looked like there was a x-stretch. Perhaps there's a difference between the display size and the actual image size resulting in the squish? -Original Message- From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Rahkonen Jukka Sent: Friday, August 20, 2010 10:54 AM To: Josh Jordan; mapserver-users@lists.osgeo.org Subject: Re: [mapserver-users] maps all look squished Hi, I am pretty sure that it is a projection problem.
