Analyze Airport Features (Aviation Tools)

Summary

Analyzes specified point features around an airfield to find and record information such as distance from a given runway centerline or the end of the nearest runway and its designation.

Usage

• The Input Analysis Features parameter value does not need specific field schema. Only the geometry field and OBJECTID field are required.

• In the absence of shape z-values in the input airport features, when Shape Z is specified as the Input Analysis Features Height parameter value, a height of 0 (zero) will be used.

• If the Input Analysis Features parameter value contains a description field, the description field and values will be included in the output. The name of the description field can be one of the following:

  • DESC

  • DESCRIP

  • DESCRIPTION

• A 5-nautical mile search radius will be used to filter searches when the tool locates the nearest features to the Input Runway Features parameter value.

• If the Input Runway Features parameter value contains a runway designation field, runway designation values will be included in the output. The name of the runway designation field can be one of the following:

  • RWYDESG

  • DESIGNATOR_TXT

  • RUNWAYDESIGNATORIDENTIFIER

• If the input runway end-point or airport reference point features are not provided, the resulting output fields will be empty.

• If the Runway End Features parameter value contains a runway end designation field, runway end designation values will be included in the output. The name of the optional runway end designation field must be RUNWAYENDD. The optional RUNWAYENDD attribute will be used to populate the NearestRunway column in the output table.

• The tool populates several fields in the Output Table parameter value. The following diagram illustrates how these fields are calculated:

  

  The following table describes the fields in the Output Table parameter value:

  Output column name	Output column alias	Description
  Elevation	Elevation	The elevation height of the Input Analysis Feature parameter value.
  ELEVATIONVUOM	Elevation Vertical Unit of Measure	The vertical unit of measure. This will be reported as one of the following: The coordinate system's vertical unit of measure belonging to the input analysis feature class. This will be used if the Input Analysis Features Height Unit parameter value is derived from the SHAPE_Z value. The unit specified for the Input Analysis Features Height Unit parameter when a specific value is used to represent the height.
  Description	Description	The Description attribute from the Input Analysis Features feature class.
  DirectionFromCenterline	Direction From Centerline	The intercardinal direction that the input analysis feature lies relative to the associated runway centerline.
  DirectionFromThreshold	Direction From Threshold	The intercardinal direction that the input analysis feature lies relative to the associated runway threshold.
  Dist_DTHR_PtAbeam	Distance Displaced Threshold to Centerline Point Abeam	The distance from the displaced threshold to the centerline (or extended centerline).
  Dist_THR_PtAbeam	Distance Threshold to Centerline Point Abeam	The distance from the threshold to the centerline (or extended centerline) point abeam the input point.
  DistanceFromCenterline	Distance From Centerline	The shortest distance from the runway centerline to the analysis point.
  DistanceFromExtendedCenterline	Distance from Extended Centerline	The shortest, perpendicular distance from the runway extended centerline to the analysis point.
  DistanceFromThreshold	Distance from Threshold	The direct distance from the threshold point to the analysis point. If the threshold point is not found, this value will be calculated from the runway end point.
  HUOM	Horizontal Unit of Measure	The coordinate system's horizontal unit of measure belonging to the input analysis feature class.
  NearestRunway	Nearest Runway	The runway end designator from the associated feature point in the Runway End Features feature class, from the RUNWAYENDD attribute.
  ObjectID	ObjectID	The ObjectID of the output table.
  OffsetDirection	Offset Direction	The side, left (L) or right (R), that the input feature lies relative to the landing direction of the extended runway centerline.
  PointID	Point ID	The ObjectID from the Input Analysis Feature parameter value associated with this output row.
  PointSource	Point Source	The workspace path that the input analysis features are from.
  RWYDESIG	Runway Designator	The Runway Designator attribute from the associated polyline from the Input Runway Features feature class.
  X	X	The x-coordinate of the input analysis feature in the horizontal units of measure.
  Y	Y	The y-coordinate of the input analysis feature in the horizontal units of measure.

• If no Runway End Features parameter value is provided, the end of the input Input Runway Features polyline will be used as the end of the runway.

  Note:

  When no value is provided for the Runway End Features parameter, there is no way to identify the runway end designator for the provided runway.

• If the Airport Reference Point Features parameter value is provided, the input feature class must contain the following fields:

  Field name	Data type
  POINTTYPE	Text
  RUNWAYENDD	Text

  These field values will be used to locate the nearest displaced threshold point. If the value specified for the Input Runway Features parameter does not contain these fields, the closest runway end point from the Runway End Features parameter value will be used.

  If the Airport Control Point Features parameter value is provided, the tool will search for the location of the runway threshold points by finding features with a POINTTYPE value of DISPLACED_THRESHOLD. If no threshold point is found, or if this feature class is not provided, the calculations for DistanceFromThreshold and Dist_DTHR_PtAbeam will be impacted.
