eml-spatialVector
The eml-spatialVector module - Logical information about
non-gridded geospatial image data
The eml-spatialVector module allows for the description of
spatial objects in a GIS system that are not defined in a
regularly gridded pattern. These geometries include points and
vectors and the relationships among them. Specific attributes of
a spatial vector can be documented here including the vector's
geometry type, count and topology level.
all spatial datasets that contain spatial data
entities represented as vector features.

Spatial Vector
Description of a spatial data entity based on features
represented by vectors
Description of a spatial data entity based on features
represented by vectors
Spatial Vector Type
Attribute List
The list of attributes associated with this
entity.
The list of attributes associated with this
entity. For more information see the eml-attribute
module.
Constraint
Description of any relational constraints on
this entity.
Description of any relational constraints on
this entity. For more information see the eml-constraint
module.
Geometry
Type of geometric feature(s) represented in the
entity.
Geometric feature classification is based on an
enumeration of simple feature classes defined by the OpenGIS
consortium and implemented in Geographic Markup Language as
simple feature types.
polygon
Geometric Object Count
Total number of the geometric objects
occurring in the dataset.
Total number of the geometric objects
occurring in the dataset.

Topology Level
Code which identifies the degree of
complexity.
This element describes the relative complexity
of the geometric information in the data file.

Spatial Reference
Horizontal Accuracy
Horizontal positional accuracy of the data
Horizontal positional accuracy of the data
expressed as either text or quantitative assessment.
Vertical Accuracy
Vertical positional accuracy of the data

Data Quality Type
Accuracy Report
A qualitative statement about the accuracy of the data.
A text statement of the data quality, included the means by which it was determined.
Quantitative Accuracy Report
A quantitative assessment of the data quality.
A quantitative assessment of the data quality expressed as a value and
the method of its determination.
Quantitative Accuracy Value
The value resulting from the accuracy test.
The value resulting from the accuracy test. Typically, this will be expressed
in units corresponding to those declared for the parameter being assessed.

Quantitative Accuracy Method
The method used to calculate the accuracy value.
Identification and explanation of the method used to calculate the quantitative
accuracy assessment.
Error expressed as root mean square of 5 control points.
