Esri announced earlier this summer that they were making over 175,000 historical maps from the USGS available online. The maps are available to anyone to view online using their web map viewer. Or ArcGIS online subscribers can have access to high-resolution geo-referenced raster images for use in their ArcGIS projects and web mapping projects. Very cool!

Midwest Flooding – Collection of Links
The Association of State Dam Safety Officials has a nice collection of links and article summaries for the recent devastating flooding that has hit the Midwest U.S. They do a nice job of breaking it down by state as well. (Image of flooding in Cedar Rapids, IA on 6/13/08. Photo by USGS)
ArcGIS API for Google Maps
From Google Maps Mania Blog:
The ArcGIS JavaScript Extension for Google Maps allows map developers to extend the Google Maps API to use ArcGIS Server services. With the extension, you can add your own data to a Google Map and embed this map in your own page.
ESRI have a number of examples of what can be achieved using their new API. Examples and reference for the API can be found here. Using the API you can:
- Display your own maps on top of a Google Maps base map.
- Execute a GIS model and display the results in Google Maps.
- Search for features in your GIS data and display the results on Google Maps.
- Find addresses using your own address locator and display the result on Google Maps.
- Display attributes from your GIS data on the map using the Google Chart API.
- Allows others to add GIS functionality from your server as a Google Mapplet.
On the surface, it seems like this news would only be of interest to GIS professionals and geeks like me. But the truth as I see it is that this development for extending the popular ArcGIS platform to the internet will lead to a whole host of new online applications and mashups that will be both fun and useful.
