Building Offsets (Defense Mapping)
Summary
Esri Defense Mapping cartographic production tool that aligns, moves, or hides building marker symbols based on a specification defined in an .xml file.
The .xml file contains settings for the following Defense Mapping cartographic products:
- MGCP TLM50
- MGCP MDG
- LTDS LDG50
Usage
-
The Defense Mapping installation directory contains .xml product files you can use for cartographic production.
Data referenced in the Product File must have representations for buildings and the linear features used for symbol alignment and conflict resolution.
Distances and units used in symbol alignment and conflict resolution are defined in the Product File.
Syntax
| Parameter | Explanation | Data Type |
Product_File |
The .xml file that contains settings specific to Defense Mapping cartographic products. | File |
Dataset |
Workspace or feature dataset that contains the buildings and linear features referenced in the .xml Product File. | Workspace; Feature Dataset |
Coordinate_System |
Sets the geoprocessing Cartographic Coordinate System environment setting. This setting determines the size, extent, and spatial relationships of features when making cartographic–related calculations. | Coordinate System |
