VCGI Web Services Expanded – Documentation Posted

VCGI, in collaboration with VT’s Enterprise GIS Consortium (EGC), has developed a portfolio of “web services” which allow users to bring map layers and imagery into their GIS projects or map mashups without actually downloading any data. By connecting to the service of choice via the internet (a live internet connection is required in order for the images to appear in your GIS project) users can access a variety of resources.

VCGI provides Web Map Services (including a basemap and contours), Imagery Services (black and white, color, infrared, various ages and resolution levels), and Geocoding Services. Services are often available in two forms: 1) cache and 2) non-cache. Cached services (*_CACHE) are designed to be used in browser or mobile web applications which utilize imagery at specific scales and need the fastest rendering performance. Non-cache services (*_NOCACHE) render the imagery to the client application dynamically; this allows clients such as ArcGIS Desktop to ask for the data in different ways (eg: different stretch or band combinations). Many of the services are also available in VT State Plane or Web Mercator projection/coordinate systems.

Services available and information on how to connect is available at the VCGI website: http://vcgi.vermont.gov/warehouse/web_services

    Can you help me locate the newest aerial photographs taken in the Burke Mountain (NE VT) area?
    Logging was done last winter which created additional woods roads. New photographs will show them.

    Thanks very much for any help you can offer.
