GIS Department News

The Manzie & Drake Geographic Information System (GIS) Department has been busy working on its in-house GIS database by entering records for over 100,000 property surveys, benchmarks and horzontal controls dating back to the 1930's. Eventually these surveys will also be scanned and added to our GIS with hyperlinks for quick viewing and printing for reference. This information will assist in performing future surveys and allow for an electronic archive of all our records. These maps, along with current CADD drawings, will be associated with the parcel map for Nassau County.

Our GIS knowledge, together with the latest technology, is used to ensure that data collection is compatible with GIS programs and database networks. Our field crews work closely with the GIS department in performing field locations. We utilize Sokkia and Trimble GPS equipment, Trimble Robotics, Trimble Pathfinder Office, ESRI ArcView and ArcPad for various projects phases of municiple GIS needs such as wetland locations, the establishment of vertical and horizontal controls and for utility locations.
