- Abstract
- United States Geological Survey (USGS) 1:250,000 Topographic Quadrangle Series Indexes is a polygon theme representing the geographic extent of USGS 1:250,000 topographic maps (1- by 2-degree quadrangles) for the coterminous U.S. forty-eight states and District of Columbia. This dataset is a part of the 2008 ESRI Data Maps collection.
- Purpose
- United States Geological Survey (USGS) 1:250,000 Topographic Quadrangle Series Indexes provides quadrangle name, identification number, publication data, and map coverage by state for each quadrangle. This small-scale index grid can be a handy visual reference for regional displays.

- Data Quality Information
- Logical Consistency Report
- The shapefile is converted to SDC (Smart Data Compression) format using either ESRI SDC Data Development Kit Professional 2 (DDKP2) or tools in ArcGIS. The SDC data set is then loaded into ArcSDE to verify and validate the geometry. Occasionally, USGS actual quadrangles depart from a completely rectangular format mainly because of map sheet production considerations in coastal areas and offshore islands that result in rotation, offset, over edge, and inset sheet layouts. These are not represented precisely by the data set, but the correct attribute information is included.
- Completeness Report
- After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
- Horizontal Positional Accuracy Report
- The geospatial part of this data set was mathematically generated using the ARC/INFO GRID? extension. In this manner, the locations of the quadrangles were computed. The positional accuracy for these quadrangles is limited only by the resolution of the data set which is 51 meters.

- Entity Type Definition
- The polygons represent a systematic grid of 1- by 2-degree quadrangles based on a latitude-longitude graticule for the coterminous U.S. forty-eight states and District of Columbia. Each 1- by 2-degree quadrangle is 128 times the area of a USGS 1:24,000 topographic quadrangle and 4 times the area of a USGS 1:100,000 topographic quadrangle.

- Attributes
- ObjectID
- Internal feature number. (Sequential unique whole numbers that are automatically generated.)
- Definition Source
- ESRI
- USGS_QD_ID
- The quadrangle identification number. The first two digits represent the latitude in degrees north, the next three digits represent the longitude in degrees west, and a hyphen, and the last two characters reveal the grid cell code within each one-degree rectangle. To understand the grid cell code within the one-degree rectangle, imagine a rectangle the shape of a door. Divide the "door" into eight rows (A-H) and columns (1-8), the lower right corner grid cell code is "A1" and the upper left corner grid cell code is "H8". Each grid cell represents a USGS 1:24,000 topographic quadrangle, hence sixty-four per one-degree rectangle. Each USGS 1:100,000 topographic quadrangle is one-half by one degree with only two fitting within the one-degree rectangle-the upper half and the lower half of the "door". The lower quadrangle's grid cell code is "A1" and the upper quadrangle's grid cell code is "E1" (these are the only grid cell codes for USGS 1:100,000 topographic quadrangles). Each USGS 1:250,000 topographic quadrangle is one by two degrees, which, is two "doors" side by side. The quadrangle's grid cell code is "A1" (this is the only grid cell code for USGS 1:250,000 topographic quadrangles).
