Weekly updates.

Terralogic Inc., Staunton, Va., launched a new website, www.topovision.com.

The site searches an online database that allows the user to view a specific location in Virginia using DRG or DOQQ base maps. The users can then download statewide USGS GIS data sets.

In addition, the site has a zoom feature, a pan feature, a previous map feature, a specific county/city zoom feature and more. The site will be continually updated and enhanced.
