Ideal Solution for Mapping system in web application

I'm building image processing or mapping system kinda like google map except we have our own HD images so i'm not sure what is the best way to do this in .NET here is what im trying to do

Mapping web application build in .NET i've High resolution images , the user first load the selected area a full scaled image should be loaded 100% (original image) then he Zoom to the area he want, then he can move around this area almost like google map

1.user select area - full scaled image loaded 2.user zoom to random area - (i will receive some values for X, Y, etc.. in query string then i will extra开发者_运维百科ct these values and zoom/return the image based on these values)

So i'm not sure what is the ideal solution for this is it just zoom/re-size image based on the vales received from the user, or its more complicated than that?

is there any resources or samples, or any other projects done like this

I haven't yet used it, but I'd start at the Google Maps API. I understand it allows for custom tiles.
