Entity_and_Attribute_Information:
Detailed_Description:
Entity_Type:
Entity_Type_Label: 30x60-minute Quad Polygons
Entity_Type_Definition:
Polygons at intervals of 30x60 minutes of latitude and longitude
Entity_Type_Definition_Source:
BLM
Attribute:
Attribute_Label: q100
Attribute_Definition:
The USGS Ohio code for the 100K (.5 degree X  1 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: 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: name_
Attribute_Definition:
Quadrangle name
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:
The format of the quad code is translated from the format typically provided by USGS. Translation is 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.
