GeographicDomainType

Structures the response domain for a geographic point to ensure collection of relevant information. The point may be associated with a polygon (such as the centroid of the polygon) or a line (end or shape points of a line). Note that the common response domain objects (OutParameter, ResponseCardinality, and ContentDateOffset) are available at each of the response objects in the representation.

Offset

string

0..1

A definition of the standard offset used when taking a coordinate reading on the geo-referenced object.

GeoreferencedObject

CodeValueType

0..1

The standard object for which the geographic coordinates are being captured. This could be a household, village centroid, etc. Supports the use of a controlled vocabulary.

AddressMatchType

CodeValueType

0..1

Use for coordinates obtained through address matching only. Identify the address matching method. Example: street segment match, ZIP code centroid, etc. Supports the use of a controlled vocabulary.

CoordinatePairs

CoordinatePairsType

0..n

Field to capture coordinate pairs as individual pairs or as an array of pairs.

AlternateOffset

TextDomainType

0..1

If unable to use the standard offset, allows entry of a non-standard offset figure.

AlternateObject

TextDomainType

0..1

If the default geo-referenced object is unavailable or cannot be measured, allows identification of an alternate object.

AlternateCoordinateSystem

TextDomainType

0..1

Specifies the coordinate system used for a response if different from that stated in the response structure.

PointFormat

string

1..1

The type attribute is used by the documenter to describe the numeric response domain.

SpatialPrimitive

string

1..1

Indicates the spatial primitive object which the point references.

Description

RecommendedDataType

CodeValueType

0..1

This field provides the recommended treatment of the data within an application. The value should come from a controlled vocabulary - recommended values include the set found in W3C XML Schema Part 2, but excluding string sub-types, QNAME, and NOTATION. The DDI Alliance has provided a controlled vocabulary (DataType) to support this element at http://www.ddialliance.org/controlled-vocabularies.

GenericOutputFormat

CodeValueType

0..1

This field provides a recommended generic treatment of the data for display by an application. The value should come from a controlled vocabulary.

MeasurementUnit

CodeValueType

0..1

Records the measurement unit, for example, ‘km’, ‘miles’, etc. Supports the use of a controlled vocabulary.

MissingValue

string

0..1

List the values used to represent missing data in a space delimited array. Use of MissingValuesReference is preferred. If this content does not match the values provided in the MissingValuesReference, the content of the MissingValuesReference overrides the content of this attribute.

BlankIsMissingValue

boolean

0..1

When value is true a blank or empty variable content should be treated as a missing value. Use of MissingValuesReference is preferred.

ClassificationLevel

string

0..1

Indicates the type of relationship, nominal, ordinal, interval, ratio, or continuous. Use where appropriate for the representation type.
