240 © 2016 Open Geospatial Consortium ● Range: 0 to 999 ● Usage Note: Recommended for linear features. If absent, client-devices are required to default to a value of 3 – Omni-directional ● Unit: NA ● Default: 3 ● Compatibility: OGC CDB 1.0 and DIGEST

5.7.1.3.19 Density Measure DML

Description: Percentage light coverage at night expressed as a percentage within the area delimited by an polygon feature. ● Identifier: DML ● Code: 0018 ● Data Type: numeric ● Length: 3 characters ● Format: integer ● Range: 0 to 100 ● Usage Note: Recommended. Applies to Geopolitical Dataset polygon features that delineate inhabited areas. If this field is absent, client-devices shall assume 0. ● Unit: Percentage ● Default: ● Compatibility: OGC CDB 1.0

5.7.1.3.20 Density Measure roof cover DMR

Description: Roof cover measure by percent within area of feature. ● Identifier: DMR ● Code: 0019 ● Data Type: numeric ● Length: 3 characters ● Format: integer ● Range: 0 to 100 ● Usage Note: Recommended for Polygon features. If absent, client-devices shall assume 0. ● Unit: percentage ● Default: ● Compatibility: OGC CDB 1.0, DIGEST 2.1

5.7.1.3.21 Density Measure structure count DMS

Description: Number of man-made, habitable structures per square kilometer. ● Identifier: DMS ● Code: 0020 ● Data Type: numeric 241 © 2016 Open Geospatial Consortium ● Length: 5 characters ● Format: integer ● Range: 0 to 99,999 Note: differs from DIGEST range of -32767 to 32768 ● Usage Note: Recommended for Polygon features. If absent, client-devices shall assume 0. ● Unit: NA ● Default: ● Compatibility: OGC CDB 1.0, DIGEST 2.1

5.7.1.3.22 Density Measure treecanopy cover DMT

Description: Canopy cover measure by percent within area of feature during the summer season. ● Identifier: DMT ● Code: 0021 ● Data Type: numeric ● Length: 3 characters ● Format: integer ● Range: 0 to 100 ● Usage Note: Recommended for Polygon features. If absent, client-devices shall assume 0. ● Unit: percentage ● Default: ● Compatibility: OGC CDB 1.0, DIGEST 2.1

5.7.1.3.23 End Junction ID EJID

Description: A Junction Identification Number that is used to virtually connect the end point of a lineal to another point, lineal or polygon feature. Lineal features stored in the same vector file having the same SJID or EJID are connected. Lineal features stored in different vector files having the same SJID or EJID as the JID listed in the corresponding tile 2D relationship file are connected. ● Identifier: EJID ● Code: 0022 ● Data Type: text numerals ● Length: 20 characters ● Format: unsigned integer64 as character string ● Range: 0 to 2 64 – 1 ● Usage Note: Mandatory for all features belonging to Topological Network Datasets. Attribute is stored as a character string representing an unsigned 64-bit number, and requires conversion back into numerical representation by client reader. This is due to the 32-bit limitation on integer values within dBASE files. ● Unit: NA ● Default: None 242 © 2016 Open Geospatial Consortium ● Compatibility: OGC CDB 1.0
