Building National Spatial Data Infrastructures

Leveraging The National Map Services in User Defined Mash-ups

—Sam Wear, Westchester County, NY

This presentation will provide an overview of how new The National Map web services (http://viewer.nationalmap.gov/viewer/) can be combined with other authoritative federal government map services, regional and state services, and large scale local government cadastral services. The combined map services can also be integrated with local user defined datasets being generated to support scientific research work and other government business programs.

As the use of map service technology becomes more standardized and accepted across governments and industry, The National Map viewer can be used as a "portal" of authoritative map services which can be integrated – or mashed-up - in viewers such as ArcGIS Explorer with other map services or other local datasets. These mash-ups, or new user "instances", provide enhanced user flexibility and productivity by aggregating data and customizing views – in the user's viewer of choice - which support specific business needs.
