Description:
Abstract:
Statewide hillshade raster surface of Rhode Island derived from a derivative of a digital elevation model originally produced as part of the Northeast LiDAR Project in 2011.
Purpose:
Transportation planners and consultants in Rhode Island need ready access to accurate geospatial data to assist in the development of plans and bids for construction projects. These same data are of prime importance in evaluating the potential impacts of climate change, including the vulnerability of existing infrastructure to environmental hazards and sea level rise. Complete, accurate, and consistent high resolution elevation data is a key geospatial data layer used in these applications, yet these data remain largely inaccessible by the user community due to unique file structures and large file sizes.
Supplemental_Information:
2010 saw the beginning of The Northeast Multiphase LiDAR Project. Across the region, the same problems were being addressed – the almost total lack of contiguous, consistent, high-resolution elevation data. Coordinated by the USGS with representatives from each of the participating states, this work sought to collect seamless LiDAR data for all of the coastal counties between New York and Maine. With accuracies 25 – 100 times better than what is currently available for much of Rhode Island, a contiguous and consistent elevation dataset derived from this new data collection initiative will facilitate a number of statewide applications including transportation planning, floodplain mapping, and hazard mitigation. As part of this project, the contractor delivered to the State of Rhode Island raw and classified LiDAR points along with a hydro-flattened 1m digital elevation model (DEM).
The DEM was delivered by the contractor in a UTM meters, NAD83, NAVD88 coordinate system. These data were reprojected to RI State Plane feet, NAD83 and vertical units were converted to feet. The NAVD88 vertical datum remained unchanged.
This particular hillshade raster surface was generated using Esri ArcGIS 10.1 using the default parameters. A vertical exaggeration of 5x was applied.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The project area required LiDAR to be collected on 1.0 meter GSD or better and processed by Photo Science to meet a bare earth vertical accuracy of 15 centimeters RMSEz or better to support 2' contour.
Logical_Consistency_Report:
The source raster DEMs were tested by Photo Science for both vertical and horizontal accuracy. All data is seamless from one tile to the next, no gaps or no data areas. No further tests were conducted by the URI Environmental Data Center.
Completeness_Report: Datasets contain complete coverage of tiles.
Positional_Accuracy:
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Raster DEMs were tested by Photo Science for both vertical and horizontal accuracy. All data is seamless from one tile to the next, no gaps or no data areas. The vertical unit of the data file is in decimal meters with 2-decimal point precision.
The reported RMSEz value was determined using the calibration control points, and not the Blind Control. The calibration control points are the same points that were used to remove any bias in the dataset before bare earth editing.
The listed RMSEz value shown below was calculated from the ground (ASPRS Class 2) data in the final Classified LAS file.
Quantitative_Vertical_Positional_Accuracy_Assessment:
Vertical_Positional_Accuracy_Value: 0.22
Vertical_Positional_Accuracy_Explanation:
RMSE in feet, as calculated from Classified LAS files by Photo Science.
