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. yes 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. 24 Topology Level Code which identifies the degree of complexity. This element describes the relative complexity of the geometric information in the data file. geometryOnly 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 Vertical positional accuracy of the data expressed as either text or quantitative assessment. Geometry Type Topology Level Type 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. 4.5 Quantitative Accuracy Method The method used to caclulate the accuracy value. Identification and explanation of the method used to caclulate the quantitative accuracy assessment. Error expressed as root mean square of 5 control points.
