Hi,
 
You have decided to take the most rocky road that exists. Georeferencing 
scanned paper maps is not extra easy and I have not seen many good, easy to use 
free utilities for doing that. If you just want to learn Mapserver I would 
recommend you to acquire some ready, georeferenced images to start with.  But 
if you are not afraid then just go ahead.
 
First, your Mapserver map will remain empty because your output extents are 
EXTENT -2200000 -712631 3072800 3840000
 UNITS DD
while all your scanned maps have their upper left corner at point zero, zero
Upper Left  (    0.0,    0.0)
 
By the way, unit DD in the mapfile means decimal degrees but judged by number 
values in extent line I guess that they mean meters.
 
What you should do is to georeference your scanned images. It means that in 
some way you must tell Mapserver what place on Earth the images are presenting. 
 In most simple case giving coordinates of one corner and pixel sizes in 
east-west and south-north direction is enough. That is the information that 
ESRI style world file is giving.  For scanned maps it may not give very good 
results because images are more or less rotated.  Therefore more ground control 
points (GCP) would be needed. If the original map has coordinate grid then 
finding good GPSs is easy.  
 
A rather simple to use georeferencing utility that I have tried is available as 
Quantum GIS plugin.  Unfortunately it did not do very good job for me but it 
may have been improved since then.  I have been mostly feeding coordinates 
manually for gdal_translate utility and warped images then to target projection 
with gdalwarp but I wouldn't say that its a great pleasure to work like that.  
Combining the user interface of QGis and gdal_translate-gdalwarp chain would 
give rather a nice tool for georeferencing.
Or maybe the same functionality could be added to OpenEV that comes with 
FWTools package.
 
By the way, most simple way to get your scanned image visible is to adjust 
mapfile extents to suit your imagery there around point 0,0.  No other data 
would suit with your image but at least you can see that the system works.

        Dear Rahkonen,
        
        Thank you for your mail, it was very helpful.
        
        I have done the following:
        
        1) Converted my .jpeg files to .tif and run the gdaltindex program to 
georeference them. It returned a .shp, .shx and .dbf files. But I don't have 
any .tfw file yet. Please see output of GDALTINDEX below.
        
        2) I tested my .map file with the shp2img utility and it generated a 
blank (white) .png file for me. Expectedly, the same blank file displays as 
blank in the browser (i.e. Ka-Map UI).
        
        My new questions:
        
        1) My maps were scanned from a paper map, does this affect my ability 
to Georeference them? 
        2) How do I determine the Projection of the scanned map images?
        
        Thanks.

                Hi,
                 
                First of all your jpeg files need to be georeferenced.  Jpeg 
files are most often georeferenced with world files which are named as .jgw.  
Sometimes they are named as .tfw, even that name is actually reserved for tiff 
files.  And Mapserver understands also world files named as .wld.
                If your images are georeferenced you can continue to building 
one single layer from all of your images.  It is done with gdaltindex utility 
program.  Gdaltindex is building a shapefile that records the extents of all 
the images to be indexed.
                Third step is to make a new raster layer that is using the 
shapefile index as a catalogue for finding the actual image files that needs to 
be opened when user is requesting a map from a certain area.
                 
                This should be enough to show you images as a single layer.  It 
would be a benefit to know the projection where the images are because 
otherwise they cannot be reprojected.  And for optimising performance it may be 
good to convert jpeg images to tiffs, but you can just start from jpegs and see 
if you are happy with the speed.
                In conclusion:
                1. Check georeferencing and projection, gdalinfo program is a 
good help in this.
                2. Make tileindex with gdaltindex
                3. Make a new raster layer in mapfile referring to just created 
tileindex file.

Data as Input
                        
                        
                        Hello Everyone,
                        
                        I am new to MapServer, however I am working on an 
application that is similar to Google Maps albeit with my own custom maps.
                        
                        The problem is:
                        
                        1) I have several maps mostly in .jpeg format and would 
like to use them as Data Inputs for this Web Application. I can't seem to get 
it done correctly. Must I convert these maps to a SHAPEFILE i.e. .shp or what? 
If so, how do I convert them?
                        
                        My development platform is:
                        
                        - Microsoft Windows XP
                        - Ka-Map
                        - MapServer (MS4W)
                        
                        Thanks.
                        
                        NB: I am re-reading the documentation for a solution.
