Entity_and_Attribute_Information:
Detailed_Description:
Entity_Type:
Entity_Type_Label: 7.5-minute Quad Polygons
Entity_Type_Definition:
Polygons at intervals of 7.5 minutes of latitude and longitude
Entity_Type_Definition_Source:
BLM
Attribute:
Attribute_Label: objectid
Attribute_Definition:
Internal feature number.
Attribute_Definition_Source:
ESRI
Attribute_Domain_Values:
Unrepresentable_Domain:
Sequential unique whole numbers that are automatically generated.
Attribute:
Attribute_Label: alt_ohiocode
Attribute_Definition:
The USGS Ohio code for the 24k (7.5-minute) quad, with the row/column coding listed last.
Attribute_Definition_Source:
BLM
Attribute_Domain_Values:
Unrepresentable_Domain:
Ohio Code for the quad, with the row/column coding listed last; for example, 44117A2 (in which the 44 is the latitude, 117 the longitude of the SE corner of a one degree by one degree block; 'A" refers to the first 7.5' row and '2' refers to the second 7.5' column, as measured from the SE corner.
Attribute:
Attribute_Label: name
Attribute_Definition:
The name of the 24k quad.
Attribute_Definition_Source:
BLM
Attribute_Domain_Values:
Unrepresentable_Domain:
A name up to 30 characters long. This will be the most current name given to a 24k quad, as determined by a query of the GNIS database.
Attribute:
Attribute_Label: ohiocode
Attribute_Definition:
The USGS Ohio code for the 24k (7.5-minute) quad, with the row/column coding listed first.
Attribute_Definition_Source:
BLM
Attribute_Domain_Values:
Unrepresentable_Domain:
Ohio Code for the quad, with the row/column coding listed first; for example, A244117 (in which the 44 is the latitude, 117 the longitude of the southeast corner of a one degree by one degree block; 'A' refers to the first 7.5' row and '2' refers to the second 7.5' column, as measured from the southeast corner).
Attribute:
Attribute_Label: old_name
Attribute_Definition:
The alternative name of the 24K quad, usually the old name of a quad that has been renamed.
Attribute_Definition_Source:
BLM
Attribute_Domain_Values:
Unrepresentable_Domain:
A name up to 30 characters long. A value will only be present if there is a known previous name or alternative name for the quad and that name can be verified with the USGS.
Attribute:
Attribute_Label: q100
Attribute_Definition:
The USGS Ohio code for the 100K (1 degree X .5 degree) quad.
Attribute_Definition_Source:
BLM
Attribute_Domain_Values:
Unrepresentable_Domain:
100K Ohio code for the quad; for example, E145120 (in which the 45 is the latitude, 120 the longitude of the southeast corner of a one degree by one degree block; 'E' refers to the fifth 7.5' row and '1' refers to the first column in a 1 degree x 1 degree quad, as measured from the southeast corner). All 100K Ohio codes begin with either 'A1' or 'E1', as this is derived from the 7.5-minute quad located in the southeast corner of the 100K quad.
Attribute:
Attribute_Label: shape
Attribute_Definition:
Feature geometry.
Attribute_Definition_Source:
ESRI
Attribute_Domain_Values:
Unrepresentable_Domain:
Coordinates defining the features.
Attribute:
Attribute_Label: SHAPE_Length
Attribute_Definition:
Length of feature in internal units.
Attribute_Definition_Source:
ESRI
Attribute_Domain_Values:
Unrepresentable_Domain:
Positive real numbers that are automatically generated.
Attribute:
Attribute_Label: SHAPE_Area
Attribute_Definition:
Area of feature in internal units squared.
Attribute_Definition_Source:
ESRI
Attribute_Domain_Values:
Unrepresentable_Domain:
Positive real numbers that are automatically generated.
Overview_Description:
Entity_and_Attribute_Overview:
There are two attributes and descriptions, for the most part identical, of the Ohio code of a quad. The second attribute (ALT_OHIOCODE) is in the format provided by USGS. Translation to the format used in the first attribute (OHIOCODE) was required for use in many database programs (e.g. Informix, Oracle) because often, when dealing with a character field, the database program will not accept a numeral in the first space.
