[mapserver-users] Photo Viewer

[Basques, Bob (CI-StPaul)]

Ok, I sort of got something to work . . .

http://gis.ci.stpaul.mn.us/datasets/SHP/SAINT_PAUL/PUBLIC_WORKS/TEST/image_pixel_coord_public.map

http://gis.ci.stpaul.mn.us/datasets/SHP/SAINT_PAUL/PUBLIC_WORKS/TEST/image_pixel_coord_public.map?mapext=750+600+1100+925

Danged if I can figure out how to rotate the image (via the world file), nothing is happening with edits to the world file.

Still not responding to all the CGI parameters either.

MAPFILE:

MAP

    NAME PHOTO
    SIZE 2048 1536
    EXTENT 0 0 2048 1536
    UNITS feet

    LAYER
          NAME "photo"
          DATA "up_a_tree.jpg"
          TYPE RASTER
          TRANSFORM FALSE
          STATUS DEFAULT
          UNITS PIXELS
    END

END

WORLD FILE:

1.0000
0.0000
0.0000
1.0000
0.5
0.5

I would think it could be done, your extent would be given in pixels. Full extent is given as 0 0 width-1 height-1. Depends if the raster code respects the layer TRANSFORM parameter.

Eric,

Interesting idea.  I remember a thread a few years back about something similar being asked.

As far as the geo-referencing part, you can simply use the size of the image as your reference coordinate system for each image.  Mapserver is more generally suit towards combining different data into a single output, thus the need for a coordinate system to reference more than one layer.

So, the real question boils down to a technique for fooling MapServer into some sort of projection some how for each image.   Let me think on this a bit.  I wonder though about setting up something to register images to a location via a loading form which grabs the image size, etc.  Then they are put away with the sudo projection assigned to each image at the uploading point.

I would like to use MapServer as just an unreferenced image viewer for jpgs so I can zoom in and out on the image.  Everything I read says that images have to be georeferenced.  Any idea or even examples would be greatly appreciated.

Thanks,
