Woolpert, Inc 20170731 Raster digital data Product: Intensity Images. Geographic Extent: The AOI is covering approximately ±907 square miles of Dodge County along with a 100-foot buffer zone outside the county for the lidar data. Dataset Description: N WI Dodge County Lidar 2017 B17 Lidar project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.70 meter. Project specifications are based on the U.S. Geological Survey National Geospatial Program Lidar Base Specification, Version 1.2. The data was developed based on a horizontal projection/datum of NAD 1983 2011 WISCRS Dodge and Jefferson Survey Feet and vertical datum of NAVD88 (GEOID12B), Survey Feet. Lidar data was delivered as; flightline-extent raw LAS v1.4 swaths, classified point cloud LAS v1.4 files formatted to 1351 individual 4,500’ x 4,500’ tiles in NAD 1983 2011 WISCRS Dodge and Jefferson Survey Feet. Derivatives were produced as tiled; Bare Earth Surface DEMs (Erdas IMG and ESRI ArcGrid Format), Intensity Images; all tiled to the same 4,500’ x 4,500’ schema. Ground Conditions: Lidar was collected in April of 2017, while no snow was on the ground and rivers were at or below normal levels. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, Woolpert established a total of 15 ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. Additional independent accuracy checkpoints were collected (58 NVA points and 48 VVA points) and used to assess the vertical accuracy of the data. These checkpoints were not used to calibrate or post process the data. The Dodge County Wisconsin QL2 Lidar 2017 project was collected in April 2017. The lidar data will deliver benefits and provide transformational data necessary to gain a better understanding of current topographic conditions within the 907 square mile county. This high-resolution QL2 lidar dataset addresses several state functional activites including: flood-risk management, infrastructure and construction management, urban and regional planning, natural resources conservation, water supply and quality, cultural resources preservation and management, wildlife habitat management, renewable energy resources, resource mining, agriculture and precision farming, and telecommunications.

None. However, users should be aware that temporal changes may have occurred since this dataset was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of its limitations. Acknowledgement of the U.S. Geological Survey would be appreciated for products derived from these data. Data covers the entire area specified for this project. A visual qualitative assessment was performed to ensure data completeness. No void areas or missing data exist. Intensity Image Generation Process: Terrascan software was used to create the deliverable Intensity Images. All overlap classes were ignored during this process. This helps to ensure a more aesthetically pleasing image. Global Mapper software was then used to verify full project coverage as well. The lidar intensity image is a representation of the reflectivity of the collected lidar data. This data was provided as an 8-bit grey scale raster images of the reflective surface lidar intensity data. A gridded raster file was created on a per tile basis. The task order projection information was applied to the final raster dataset. Prior to delivery, all raster files were visually reviewed to ensure coverage and reviewed using automated processes to ensure proper formatting. 20170412 Raster NAD 1983 2011 WISCRS Dodge and Jefferson Feet (ESRI Full Name: NAD_1983_2011_WISCRS_Dodge_and_Jefferson_Feet) 1.0000346418 -88.775 41.47222222222222 863999.999 0.025 row and column 2.5 2.5 U.S. survey feet D_NAD_1983_2011 GRS_1980 6378137.0 298.257222101 USGS/NGTOC mailing and physical address
