Bronze level automatically awarded US beta

This data has achieved Bronze level on 25 October 2015 which means this data makes a great start at the basics of publishing open data.

2006 Federal Emergency Management Agency (FEMA) Topographic LiDAR: Connecticut Coastline Survey

Description

LIDAR data is remotely sensed high-resolution elevation data collected by an airborne collection platform. By positioning laser range finding with the use of 1 second GPS with 100hz inertial measurement unit corrections; Terrapoint's LIDAR instruments are able to make highly detailed geospatial elevation products of the ground, man-made structures and vegetation. The LiDAR flightlines for this project was planned for a 50% acquisition overlap. The nominal resolution of this project without overlap is 1.25m. Four returns were recorded for each pulse in addition to an intensity value. GPS Week Time, Intensity, Flightline and number attributes were provided for each LiDAR point. Data is provided as random points, in LAS v1.0 format, classified according to ASPRS Class Code 2=Ground 1=Undefined. Water is included in the bare earth ground model, except where the entire tile is covered by water. The following regions of Connecticut are included in this project: Fairfield County - 130 square kilometers New Haven - 170 square kilometers Middlesex - 29 square kilometers New London - 157 square kilometers Please note that the LiDAR intensity is not calibrated or normalized. The intensity value is meant to provide relative signal return strengths for features imaged by the sensor.
