The The Lake Chelan TerraBrowser is an effort to create a more intuitive and flexible interface to the Terraserver V5.0 maps and images.
At the core of the Terraserver is a database of maps and imagery of the US, created by the US Geological Survey. In collaboration with Microsoft and some other entities, that database has been placed online.
This remarkable information is broadly useful and, to me at least, intensely fascinating. But the user interface to that data, especially the primary one located on the home page, is limited and imprecise.
My own interest in certain imagery led me to examine the server's behavior more closely, and I found that it is really quite flexible. I realized that a better means of browsing the data set could be devised.
Once I understood what could be done, I wanted to do it.
I initially devised the Terrabrowser for my own use. For that reason, and for the benefit of my local friends and clients, the original page started up with a view of lower Lake Chelan in Washington State.
By adding a US map interface, I have greatly expanded upon the TerraBrowser's range; but mainly because of my love for this beautiful region where I live, I have retained the Lake Chelan moniker and its default to a view of the Lake.
I think the TerraBrowser provides for powerful and intuitive navigation of the fascinating USGS imagery. I hope many will enjoy it.
