2007 Federal Emergency Management Agency (FEMA) Niagara County New York Lidar
The spring 2007 LiDAR Flight Acquisition required the collection of approximately 526 square miles of Niagara County and approximately 30 square miles of the corridors of Erie County. Total, approximately 555 square miles were collected at a nominal point spacing of 1.4 meters and based on the Sanborn FEMA compliant LiDAR product specification. The lidar data was collected from Jan 3 2007-May 9 2007. Multiple returns were recorded for each laser pulse along with an intensity value for each return. The lidar points in this data set are the last return data, it is not a bare earth data set and the points have not been classified. LIDAR data is remotely sensed high-resolution elevation data collected by an airborne collection platform. Using a combination of laser range finding, GPS positioning and inertial measurement technologies; LIDAR instruments are able to make highly detailed Digital Elevation Models (DEM) of the earth’s terrain, man-made structures and vegetation. This data was collected at a resolution to aid in coastal management decisions including flood plain analysis and mapping.
