Abstract:
"These files contain 2004 digital orthoimagery of Albany County, New York. Image pixel size is 1.0 ft. GSD. Image type is natural color. Image horizontal accuracy is +/-4 ft. at the 95% confidence level. Each file contains an image covering 3000 ft. by 2000 ft. on the ground. Digital elevation models used for orthorectification were compiled from several sources, all of which were compiled photogrammetrically."
Purpose:
"This digital orthoimagery 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."
Supplemental_Information:
The data obtained through The Seamless Server is considered to be the "best available" data from USGS. Historical data and other data may be obtained by contacting Customer Services, Center for Earth Resources Observation & Science, at 1-800-252-4547. Information in quotation marks, initial processing steps, accuracy reports, and source information is taken directly from the original metadata.Spatial-specific information not available

Data_Quality_Information:
Logical_Consistency_Report:
The dataset contains raster or digital ortho images so the logical consistency report is not applicable. The file naming convention was supplied by New York state and is based on the co-ordinate pair of the lower left corner of the ortho tile. When the ortho tiles were created the file names were restricted to a numeric value representing the lower left corner of the ortho tile. 10470162 which represented a tile with the lower left corner of 1047000, 162000. These tiles were then all renamed using a batch script so that they reflected the N.Y. state standard I_10470162_12_5000_col_2000.tif Consistency of file naming was ensured by the batch process.
Completeness_Report: The project consisted of 993 final tiles

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The relative accuracy is assembled by comparing rectified images generated from adjacent strips of imagery. The absolute accuracy is assessed by measuring the ground control points in the rectified image against the actual surveyed co-ordinate position. The testing is for overall accuracy.

Process_Description:
"The aerial film was acquired in 2004. The imagery was scanned at 14 microns using a Z/I Imaging Photoscan TD-1 scanner. The Ground control used to support the ortho mapping was collected by identifying strategic points on the aerial photography then determining the coordinates by ground survey techniques. The Aerial Triangulation was performed using softcopy workstations and Intergraph's ISDM software. Bundle adjustment was performed using PAT-B and Digital Elevation Models were created using standard photogrammetric collection techniques on Intergraph's SSK soft copy workstation. During the bridging process,both the DEM and the bridge deck were captured as well as the ground features surrounding the bridge. A "DTM apron" was delineated at each side of the elevated bridge and the resulting smearing is located and accumulated in the solid black apron area. The images were then ortho rectified using Intergraph's Base Rectifier software. Orthovista.Seamless mosaicing was performed using Triathlon's AIM software and the seamless mosaic was clipped into tiles using Triathlon's Clipmos software. Images were then quality controlled using Intergraph's IRASC and Adobe PhotoShop software. Final files were then compressed using MrSID. Final deliverables in tiff format with tfw files and MrSID files where placed on DVD Media."

Entity_and_Attribute_Information:
Overview_Description:
Entity_and_Attribute_Overview:
For color-infrared and natural color DOQs, a digital number from zero to 255 will be assigned to each pixel but that number will refer to a color look-up table which will contain the RGB red, blue and green (RGB) values, each from zero to 255, for that digital number. Areas where the rectification process is incomplete due to incomplete data (i.e., lack of elevation data, gaps), are represented with the numeric value of zero.
