Link - ArcIMS to Google Maps…

have debated with myself and others about if and how we should publish our large raster datasets within the Google Maps framework. State and local governments have large amounts of high quality aerial photography, often much better than what Google Maps provides. But how do small government agencies deal with the massive computing infrastructure of Google? One of the reasons people like Google Maps is that it is a fast, seamless repository of imagery (high quality in some areas, very low in others). The speed for Google Maps lies in the tiling scheme. Unfortunately the Google Map API does not allow (currently) a way to overlay an image that spans multiple tiles, if it is an image then it must conform to the tiling system. Google Earth is much different. I and others have shown how relatively easy it is to pass a network link containing ground overlays that span large areas on top of Google Earth’s base data. This is not the case for Google Maps (at least not that I have been able to see).

Jeremy has a great example of taking data you are serving out of ArcIMS and putting into a Google Maps page. There are many parts of the country that don’t have good satellite coverage in Google Maps so taking some DOQQs and serving them up can help with any Google Maps mashups you are working on. Jeremy also went into some of the details on how this works so click through to find out more.
