I have multiple individual large spatial datasets, grids/rasters around 80Gb.  What is the best way to deal with delivery of this information online.  The proposed method is to allow the user to select an area eg rectangle on a google map interface. The rectangle geographic extent coordinates are used to issue the subset instructions and generate an output image of the area of interest. Instead of processing the image extraction from the large dataset I was looking at a solution that stitches image tiles together at resolution based on the area of interest. My questions relate to the following areas;

1. Type of OS / Scripting Language or Framework of the server (eg Linux/Python Windows/.NET (my primary technology)). Pls note CLOUD systems are NOT an option.
2. Perform Subsetting on a remote server or Supply Subset PNG8 images on the main server that get stitched together.
3. Open source systems that already achieve this.

Geoserver appears to be a potential solution.
