2003 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Yakima County, Washington
This kmz file shows the extent of coverage for the 2003 PSLC Yakima County, WA lidar data set.
TerraPoint surveyed and created this data for the Puget Sound LiDAR Consortium under contract. The area surveyed is approximately 77 square miles and covers a portion of Yakima County, WA. All data was collected during ideal conditions (leaf-off). The LAS files were derived from all returns ASCII files contain the X,Y,Z values of all the LiDAR returns collected during the survey mission. The GPS time, scan angle, intensity classification and return numbers of each point were preserved in the conversion from ASCII to LAS. ASPRS Classifications were used: Class 1 (Unclassified) and Class 2 (Ground). Futher details are available in the Process Steps below. The NOAA Coastal Services Center noticed that some intensity values are 0, so be aware before using the intensity information. This dataset was flown in 2003 with a 50% overlap between flight lines. Due to the overlap the nominal point spacing of the dataset is 1.0 meter.

|Data Presentation Form:||
|Dataset Progress Status||Complete|
|Data Update Frequency:||As needed|
|Purpose:||The LAS files can be used to create DEMs and also to extract topographic data in software that does not support raster data. Other surface features can also be extracted with custom applications. This high accuracy data can be used at scales up to 1:12000 (1 inch = 1,000 feet). LiDAR data has a wide range of uses such as earthquake hazard studies, hydrologic modeling, forestry, coastal engineering, roadway and pipeline engineering, flood plain mapping, wetland studies, geologic studies and a variety of analytical and cartographic projects.|
