As the tidal waters moved throughout the Bay, flights were completed according to tide data provided by the University of California - Davis (Evolution & Ecology Dept.). Flights were completed during all acceptable periods - day or night.

Data quality info: Data quality: Scope: Scope: Hierarchy level: Scope code: dataset Report: Quantitative attribute accuracy: Name of measure: Accuracy Evaluation method description: Independent ground control points were acquired using static GPS methods in flat open areas throughout the project area. These points were estimated to have a vertical accuracy of 0.02m. The processed lidar data were compared to ground control points within the project. Lidar points surrounding the x-y of each ground control point were located. A triangulated irregular network (TIN) model was created and a z value was interpolated. The interpolated Lidar z value at ground control x-y was compared to the ground control z. The mean elevation difference for all comparison was used to estimate and remove an elevation bias within the Lidar data. The elevation bias was determined to be 0.137m. Removal of the bias resulted in a RMSE of 0.128m. Processing steps (datum conversion, projection, grid interpolation, etc.) introduce additional error factors which have not been tested and factored into the reported error. Result: missing Report: Absolute external positional accuracy: Name of measure: Horizontal Positional Accuracy Evaluation method description: RMSE at 1 sigma = 21 cm Result: missing Report: Absolute external positional accuracy: Name of measure: Vertical Positional Accuracy Evaluation method description: RMSE at 1 sigma = 12.8 cm Result: missing Report: Completeness commission: Name of measure: Completeness Report Evaluation method description: None available Result: missing Report: Conceptual consistency: Name of measure: Conceptual Consistency Evaluation method description: Lidar Specifications: 7,000-feet AMT flight height; 24 degree field of view, 2.84-meter average post-spacing, 2978-foot swaths flown with 30% sidelap, 24,000 pulses per second; 1+1 collection (one return and one intensity value per pulse). Lidar flown with an ADS40, Leica Geosystems Lidar system, February 2002 model. The flight consisted of 71 E/W flight lines with 2 N/S cross flight lines for data calibration purposes: 800 flight line miles covering 274 square miles. For each lift, 2 flight lines were flown at the Astoria, OR airport for system calibration purposes. Result: missing Lineage: Lineage: Statement: missing Process step: Process step: Description: The raw lidar data was checked for complete coverage following each mission and at the end of the flights. The data was pre-processed using SBG software to correctly establish the position of each x-y-z point. The data was checked again for completeness and conformance to specifications by comparisons to ground surveyed points. The Lidar data was post-processed using a customized version of TerraSolid software and bare earth terrain models were developed. Date and time: 2002-11-05T00:00:00 Process step: Process step: Description: The post-processed data from Spencer B. Gross were delivered in Washington State Plane (South) projection referenced to NAD27 with vertical elevations in US survey feet referenced to NGVD29. The data were converted to geographic coordinates using General Cartographic Transformation Program software developed by the United States Geological Survey. The data were then transformed to NAD83 using NADCON grids from the National Geodetic Survey (NGS). A final datum transformation was performed to convert vertical elevations referenced to NGVD29 to NAVD88 using NGS VERTCON grids. A comparison of the lidar data to a ground truth data set indicated a 0.137m bias, which was removed. The data were then converted to a binary format and loaded into the Lidar Data Retrieval Tool (LDART) database.
