<div>Hi luca ,</div> <div><BR>We have developed a web-mapping application . Our mapping application uses Mapserver , Php/Mapscript as the scripitng language and MySql as the database.And this application accepts user clicks and allows the user to edit the map : adding points, etc.<BR>Now for this map , we require a base map - which is a raster layer .<BR>We have tried editing the mapfile as follows:<BR><BR>LAYER<BR>NAME "base"<BR>TYPE raster<BR>DATA "india.tif"<BR>END<BR><BR>But this is of no help. The tiff file resides in the shapefiles directory .There is no world file for this tiff file. Do we have to create one on our own ? How is it possible to create a world file out of a plain image. <BR>We want to include this raster image as our base map. Is this the right way or is there any other way?<BR><BR>Could someone please help us.<BR>Thanks<BR>Apeksha<BR><BR><BR><BR><B><I>luca marletta <lucamarle@GMAIL.COM></I></B> wrote:</div> <BLOCKQUOTE class=replbq
