Abstract: |
This data set contains three-dimensional mobile lidar elevation data for seven villages in American Samoa on the island of Tutuila. The seven villages are: Fagaalu, Fagotogo, Pago Pago, Vatia, Leone, Amanave, and Poloa. The data were collected by Sanborn Map Company on October 27 - 30, 2010 Partners in this effort were the NOAA Pacific Services Center, the American Samoa Department of Commerce, and the National Park of American Samoa. The classifications available for download from the Digital Coast are: 1. Ground (2) 2. Low Vegetation (3) 3. Medium Vegetation (4) 4. High Vegetation (5) 5. Building (6) 6. Model Key Point (8) A smooth surface can be generated from model key points.

Data Quality
Horizontal Positional Accuracy: |
Lidar compiled to meet 1m Root Mean Square Error (RMSE) horizontal accuracy. For additional information, refer to the following reports: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid12a/2497/supplemental/Final_Report_AmericanSamoa.docx https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid12a/2497/supplemental/American_Samoa_Ground_Control_Survey_Report.doc |
---|---|
Vertical Positional Accuracy: |
The lidar data was evaluated using a collection of 49 painted target control points. The Root Mean Square Error (RMSE) is 0.064 m.

Process Steps
Process Step 1
Description: |
The Lynx Mobile Mapper was installed on a Toyota RAV4. A survey and installation calibration was performed prior to collection of the village sites. Pre-collect checks such as cleaning the sensor head glass are performed. A five minute INS initialization is conducted, with the equipment running, prior to collection, to establish fine-alignment of the INS. GPS ambiguities are resolved by collecting in the proper PDOP window and limiting obstructions. The mobile mapping team coordinated daily with DOC and the survey team for establishment of base stations and collection. A minimum of two GPS base stations were set for each America Samoa village, which is within the project area or within the required baseline specifications of the project. An initial survey approach and daily collection was planned using detailed map base data supplied by NOAA. This included planning for PDOP and satellite visibility, route planning for data integrity, and identifying areas that may potentially require additional data collection missions due to terrain, vegetation or building obscurations. At the completion of the days mission, the data was transferred to the workstation and data quality and coverage checks were performed |

Process Step 2
Description: |
The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary filters is applied as appropriate for the production of bare earth digital terrain models (dtms). Interactive editing methods are applied to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces. The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.2 format. The header file for each dataset is complete as define by the LAS 1.2 specification. In addition the following fields are included: Flight Date Julian, Year, and Class. The LAS files do not include an overlap class. The data were classified as follows: Class 2 = Ground, Class 3 = Low Vegetation, Class 4 = Medium Vegetation, Class 5 = High Vegetation, Class 6 = Buildings, Class 7 = Noise. |

Process Step 3
Description: |
NOAA OCM received the data in LAS v1.2 format. For data storage and Digital Coast provisioning purposes, the data were: 1. Converted from ASVD02 heights to Ellipsoid (Samoa) heights using Geoid09 2. Converted from UTM Zone 2 South (meters) coordinates to geographic coordinates 3. Filtered to remove outliers 4. Zipped to laz format |
