thanks for the reply, i already have a mapserver 4 windows...so, do i still need to have a geoserver? From what i read, mapserver is faster for shapefile data while the Geoserver is faster for Postgis and raster data. In this case, i only have raster data (50 satellite-image .TIF files and each of the .TIF file is 50+ mb in size) so what do you recommend me to use?

do you mean a single large Tif-file splitted into several Tif-files? well i tried loading all of
the 50 tif-files to the ArcMap and it forms a whole map. so i think they are sorted as tiles
just like the wall in the bathroom.

Mapbender is a client for a service called WMS (Web Map Service).
Your have to get a WMS from your TIF-Files at first.
This is a job for tools like UMN-Mapserver or Geoserver.
After setting up this WMS you can show it in Mapbender-Client.
Do you habe 50 "independent" Tif-Files or are they sorted as tiles
(like the wall in your bathroom)?
Organize these tiles using tileindex-function from GDAL and you will get much
better performance then merging it to one big tif.
Also have a look on gdaladdo-function to include a smaller
"overview"-map-version in every tif-file.
In smaller scale the WMS-Server has only to read the head of the tif-Files.

You cant get shape from tif.
tif is raster-data, shape is vector-Data.
But the tile-index, organizing the tiles, looks like shape (.shp, .shx).

first of all i'm still a newbie and this is my first time using mapbender
so i still need alot of advices from the experts. Ok, right now i'm building
a simple web gis for my project but I only have 50 .TIF images as my map. My
question is, is it possible to use .TIF files as a basemap or do i have to use a
shapefile? If it is possible then, how can i merge all the 50 TIF files into a
single TIF file so that will be easier to manage. Thanks for your help.
