2006 Southwest Florida Water Management District (SWFWMD) Lidar: Rutland Ranch District
Dataset Identification:
Resource Abstract:
The Light Detection and Ranging (LiDAR) LAS dataset is a survey of select areas within Rutland Ranch. This data falls in Manatee
County. These data were produced for the Southwest Florida Water Management District (SWFWMD). The Rutland Ranch LiDAR Survey
project area consists of approximately 17 square miles. The LiDAR point cloud was flown at a density sufficient to support
a maximum final post spacing of 4 feet for unobscured areas. 3001 Inc. acquired 40 flightlines on February 1, 2006. The data
was divided into 5000' by 5000' foot cells that serve as the tiling scheme. The Rutland Ranch LiDAR Survey was collected under
the guidance of a Professional Mapper/ Surveyor.

purpose:
The Southwest Florida Water Management District uses topographic information to support regulatory, land management and acquisition,
planning, engineering, and habitat restoration projects. The Rutland Ranch LiDAR Survey data will support the creation of
Federal Emergency Management Agency Flood Insurance Rate Maps (FEMA FIRM) and an integrated ground and surface water model
for Rutland Ranch. All data will be public record as defined by applicable Florida statutes. The Rutland Ranch LiDAR Survey
was collected under the guidance of a licensed and professional Surveyor/Mapper.

Use limitation statement:
These data depict the elevations at the time of the survey and are only accurate for that time. Users should be aware that
temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual
surface conditions. Users should not use this data for critical applications without a full awareness of its limitations.

Use Limitation
While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state
of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of
the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact
of distribution constitute such a warranty.

name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
All ground control processing and adjustment is performed using published coordinate horizontal and vertical datums (e.g.
NGS CORS). For deliverables, Corpscon for Windows Version 5.11.08 (geoid 99) was used for horizontal and vertical datum conversion
as well as for coordinate system conversion purposes (e.g. UTM to State Plane).
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description
The accuracy assessment was performed using a standard method to compute the root mean square error (RMSE) based on a comparison
of ground control points (GCP) and filtered LiDAR data points. Filtered LiDAR data has had vegetation and cultural features
removed and by analysis represents bare earth elevations. Testing was performed prior to gridding of the filtered LiDAR data
points and construction of the Intergraph .dtm file format. The RMSE figure was used to compute the vertical National Standard
for Spatial Data Accuracy (NSSDA). Ground control was established by 3001, Inc. A spatial proximity analysis was used to select
edited LiDAR data points contiguous to the relevant GCPs. A search radius decision rule is applied with consideration of terrain
complexity, cumulative error and adequate sample size. Cumulative error results from the errors inherent in the various sources
of horizontal measurement. These sources include the airborne GPS, GCPs and the uncertainty of the accuracy of the LiDAR data
points. This accuracy is achieved prior to the sub-sampling that occurs through integration with the inertial measurement
unit (IMU) positions that are recorded. It is unclear at this time whether the initial accuracy is maintained. The horizontal
accuracy of the GCPs is estimated to be in the range of approximately 1 to 1.6 inches. Finally, sample size was considered.
The specification for the National Standard for Spatial Data Accuracy is a minimum of 20 points to conduct a statistically
significant accuracy evaluation (Minnesota Planning, 1999, Positional Accuracy Handbook, Minnesota Planning Land Management
Information Center, St. Paul, Minnesota., p.3). Most statistical texts indicate that a minimum of 30 sample points provide
a reasonable Approximation of a normal distribution. The intent of the NSSDA is to reflect the geographic area of interest
and the distribution of error in the data set (Federal Geographic Data Committee, 1998, Geospatial National Standar
Completeness Commission
evaluation Method Description
The LAS files were flown at a density sufficient to support a maximum final post spacing of 4 feet for unobscured areas. The
bare-earth surface will contain voids in areas that were densely vegetated, covered by bridges, buildings, water, fresh asphalt,
sand etc.
