UFC Heliport (Aviation)

Available with Aviation Airports license.

Available with Aviation Charting license.

Summary

Creates obstruction identification surfaces (OIS) pursuant to the Helipad Surface specification of the UFC 3-260-01 Section 4.4 HELIPADS, prescribed by MIL-STD 3007. These surfaces provide planning, design, construction, sustainment, restoration, and modernization criteria for the United States Department of Defense. Surfaces are created as polygon or multipatch features.

Usage

• The tool creates United Facilities Criteria (UFC) surfaces in an existing polygon or a multipatch feature class. The Target OIS Features parameter value must have a vertical spatial reference.

• To create a .json file for the Custom JSON File parameter, use the CustomizeOIS.exe utility included in the Aviation Airports Product Data download available from My Esri.

• OIS tools are flexible and accept a variety of input and output feature class types. For more information, see the OIS Input and Output schemas.
