This task order consists of LiDAR data acquisition and processing for the USGS and the NRCS with the purpose of assisting with natural resource conservation efforts. The task required the LiDAR data to be collected at a nominal pulse spacing (NPS) of 0.7m. The raw lidar point cloud data was used to create classified Lidar LAS files, intensity images, hydrologic breaklines, and hydro-flattened DEM files. The LiDAR data was provided in 1,500 meters x 1,500 meters tiles in the UTM projection. The LiDAR tile file names were derived from the southwest corner of each tile and are named based on the US National Grid. This metadata file is for the classified LAS deliverable. Product specifics can be found in the processing description section of this file. |

<div style='text-align:Left;'><div><div><p><span>TASK NAME: NRCS Maine 0.7M NPS LIDAR LiDAR Data Acquisition and Processing Production Task USGS Contract No. G10PC00057 Task Order No. G13PD00954 Woolpert Order No. 073683 CONTRACTOR: Woolpert, Inc. This data set is LiDAR DEM data representing the project AOI, which encompasses approximately 2279 square miles along with a 100 meter buffer in two separate areas within Southwest Maine. LiDAR data is a remotely sensed high resolution elevation data collected by an airborne platform. The LiDAR sensor uses a combination of laser range finding, GPS positioning, and inertial measurement technologies. The LiDAR systems collect data point clouds that are used to produce highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures, and vegetation. The task required the LiDAR data to be collected at a nominal pulse spacing (NPS) of 0.7m. The final products include 2870 files containing classified LAS, one (1) meter pixel raster DEMs of the bare-earth surface in ERDAS IMG Format, and 8-bit intensity images. Each LAS file contains lidar point information, which has been calibrated, controlled, and classified. Additional deliverables include hydrologic breakline data, control data, tile index, lidar processing and survey reports in PDF format, FGDC metadata files for each data deliverable in .xml format, and LAS swath data. Collected swath files that were that were larger than 2GB were provided in multiple sub-swath files, each less than 2GB. Ground conditions: Water at normal levels; no unusual inundation; no snow; leaf off.</span></p></div></div></div> |
