Aerial Photography Extent

INDICES.Aerial_Photography_Extents is a polygon dataset of the areas where aerial photography is available in the State of Utah.

INDICES.Aerial_Photography_Extents is intended to be used to determine what aerial photography datasets are available for areas across the State of Utah.

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

  • Resolution - the resolution or pixel size of the imagery
  • 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 distributed from AGRC's FTP site
  • FTP_Path - the FTP directory to download the data from
  • 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 - the REST end point URL
  • LYR_File - a layer pointer and symbology
  • FlightDate_Location - where to find the exact flight date for each individual tile of data
  • Tile_Index - the tile index in the SGID for each product
  • Upload_Date - the date the polygon extent was loaded into the dataset

These boundaries are maintained by AGRC with the help of many state, county, and local entities. Changes and updates are made as new imagery 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.

HRO Index Sample

The High Resolution Ortophotography (HRO) tile indices can be used to determine the boundaries of the 1 foot (25cm) natural color orthoimagery tiles from 2006 and 2009.

Each tile index contain the following attribute fields:

  • TILE - the image tile name
  • PATH - the directory where the imagery tile resides on the FTP site
  • SIZE - the average file size of each tile

The native spatial reference for this dataset is UTM Zone 12N, NAD83 (0.01 meter coordinate precision).

NAIP Index Sample

The National Agricultural Imagery Program (NAIP) tile indices can be used to determine the boundaries of the 1 meter natural color orthoimagery tiles from 2003, 2004, 2006, and 2009. Color infrared/false color (CIR) imagery is available from the 2006 and 2009 datasets.

Each tile index contain the following attribute fields:

  • TILE - the image tile name
  • PATH - the directory where the imagery tile resides on the FTP site
  • SIZE - the average file size of each tile

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.

DOQ Index

The Digital Orthophoto Quad (DOQ) tile indices can be used to determine the boundaries of the 1 meter black and white orthoimagery tiles from the 1990's.

Each tile index contain the following attribute fields:

  • TILE - the image tile name
  • PATH - the directory where the imagery tile resides on the FTP site
  • SIZE - the average file size of each tile

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.
