LiDAR Extents is a polygon dataset of the areas where LiDAR elevation data is available in the State of Utah.

Each polygon extent contains the following attribute fields when available or applicable:

• Resolution - the resolution or average point spacing
• Year_Collected - the year collected
• Description - a short description
• File_Format - the file format
• File_Extension - the file extension
• Average_File_Size - the average file size of an individual image tile
• Total_Size - the total file size of the entire product collection
• Horizontal_Accuracy - the horizontal positional accuracy
• Vertical_Accuracy - the vertical positional accuracy
• Total_Square_Miles - the total square miles of the dataset
• Contact - contact information
• In_House - whether or not it is available from UGRC
• FTP_Path - the location used to store the data
• Product - a generalize product name
• Category - a generalized product category name
• Estimated_Date - an estimated date the data was collected
• HTML_Page - the URL to a webpage for the product
• REST_Endpoint - N/A
• LYR_File - N/A
• FlightDate_Location -N/A
• Tile_Index - the tile index for each product
• Upload_Date - the date the dataset was uploaded
• USGS_QualityLevel - the USGS Quality Level if applicable
• Coverage - the bare earth extents that are USGS Quality Level 1 or 2
• Project_Name - the generalized reference name for project area
• Project_Status - denotes if the project is Complete or In Progress

These boundaries are maintained by UGRC with the help of many state, county, and local entities. Changes and updates are made as new LiDAR is a acquired in Utah. The native spatial reference for this dataset is UTM Zone 12N, NAD83 (0.01 meter coordinate precision). There are no constraints or warranties with regard to the use of this dataset. Users are encouraged to attribute content to: State of Utah, SGID.
