Dear Rahkonen,<br><br>Thank you for your mail, it was very helpful.<br><br>I have done the following:<br><br>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.<br>
<br>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).<br><br>My new questions:<br><br>1) My maps were scanned from a paper map, does this affect my ability to Georeference them? <br>
2) How do I determine the Projection of the scanned map images?<br><br>Thanks.<br><br>GDALTINDEX OUTPUT (condensed):<br>==========================<br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">C:\ms4w\Apache\cgi-bin>gdalinfo c:\ms4w\apps\test\tmp\pg19.tif</span><br style="font-family: courier new,monospace;">

<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span></span></font> </div>
<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>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.</span></font></div>
<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>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.</span></font></div>
<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>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.</span></font></div>
<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span></span></font> </div>
<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>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.</span></font></div>
<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>In conclusion:</span></font></div>
<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>1. Check georeferencing and projection, gdalinfo
program is a good help in this.</span></font></div>
<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>2. Make tileindex with gdaltindex</span></font></div>

<div></div>Hello Everyone,<br><br>I am new to MapServer, however I am working
on an application that is similar to Google Maps albeit with my own custom

can't seem to get it done correctly. Must I convert these maps to a SHAPEFILE
