Esri's Utility and Pipeline Data Model (UPDM) is a geodatabase schema template for operators of pipe networks in the gas and hazardous liquids industries. UPDM is a moderately normalized data model that explicitly represents each physical component of a gas pipe network from the wellhead to the customer meter, or hazardous liquids pipe network from the wellhead to the terminal or delivery point, in a single database table object.
The Utility and Pipeline Data Model requires specific technical experience and software.
When you download the UPDM, you'll find the following files:
|Documentation||DataDictionary.htm||The data dictionary for the UPDM that includes a description of the features, fields, and domains in the data model.|
|UPDM Change Log.pdf||The release notes that describe changes made at each version of the UPDM.|
|UPDM Documentation.pdf||Adobe Reader file documenting the data model.|
|UPDM.gdb||The file geodatabase used to deliver an empty schema of the UPDM.|
|UPDM.xml||The XML workspace document used to deliver an empty schema of the UPDM.|
