LIDAR (LIght Detection And Ranging), IKONOS, and SPOT data, coupled with GPS, are providing enormous improvements in the capture of digital terrain data. The wealthier local governments are making substantial investments in spatial data to support more responsive and accountable form of services to the taxpayer. Commercial demand for street centerlines and postal code data is accelerating at the same time the Bureau of Census is releasing the 2000 census data and is contemplating the need for modernization of its TIGER database. All of these factors reinforce the Committee’s original view of a national need for a robust NSDI that is in the public domain. The Committee also appreciates that a successful NSDI must address the need for business plans that encourage private sector involvement and local government investments.
