Description:
Abstract: These files contain 2018 digital Ortho-imagery of Warren and Westchester Counties in New York State. Warren County image pixel size is 6" GSD and image type is 4-band, RGB & NIR. The Image horizontal accuracy is within 4' at the 95% confidence level (NSSDA). Each file contains an image covering 2000 ft. by 3000 ft. on the ground. Westchester county images provided by Westchester County GIS have a horizontal positional accuracy of less than or equal to 15cm. Each file contains an image covering 2500 ft. by 2500 ft. on the ground.
Purpose: This digital Ortho-imagery can serve a variety of purposes, from general planning to field reference for spatial analysis to a tool for revision of vector maps. It can also serve as a reference layer for GIS.

Data_Quality_Information:
Logical_Consistency_Report: The dataset contains raster images or digital ortho images so the logical consistency report is not applicable. The New York State Office of Information Technology Services makes no claims to the accuracy of the information in this file. THE GIS DATA IS PROVIDED AS IS AND WITHOUT ANY WARRANTY, EXPRESS OR IMPLIED, AS TO THEIR PERFORMANCE, MERCHANTABILITY, OR FITNESS FOR ANY PARTICULAR PURPOSE. NYS ITS does not represent or warrant that the GIS data is error-free, complete, current, or accurate. The file naming convention was supplied by New York State. When the ortho tiles were created the file names were restricted to a numeric value representing the lower left corner of the ortho tile. These tiles were then all renamed using a batch script so that they reflected the N.Y. state standard (i.e. "l_15510420_06_08200_4bd_2016.tif"). Consistency of file naming was ensured by using a batch process. The file naming convention consists of the first letter for Central, East, West or Long Island for New York State Plane Coordinate Systems (NYSPCS). The following four numeric characters represent the first four characters of the "X" coordinate value for the tile's lower left corner coordinate in NYSPCS and the next four characters represent the first four characters of the "Y" coordinate value for the tile's lower left corner coordinate in NYSPCS. The next two numeric characters represent the tile's Ground Sampling Distance (GSD) value in ft. The following five numeric characters represent the Above Mean Terrain (AMT) nominal height at which the Ultracam X sensor recorded or collected the original imagery for the corresponding area. The next three characters are "4bd" for 4-band ortho-photos. Lastly, the last four numeric digits represent the year in which the particular ortho was created.
