Generate Facility Entryways (Indoors)

Available for an ArcGIS organization licensed with the Indoors extension.

Summary

Creates or updates points representing a building's entry or exit locations.

This tool analyzes input unit features to identify the exterior edges of a facility and generates point features for doors located in proximity to those edges. The ArcGIS Indoors network uses these entryway points when routing into, out of, and between buildings.

Illustration

Usage

• The following input parameters can be feature layers or feature classes from an indoor dataset (created using the Create Indoor Dataset tool) or Indoors geodatabase (created using the Create Indoors Database tool): Input Level Features, Input Unit Features, and Input Door Features.

• The Input Level Features parameter value must be a polygon feature layer or feature class that conforms to the Indoors model for the Levels feature class. The generation of entryways can be limited to specific levels by making a selection on the input layer or by providing a definition query. Without a selection or definition query, the tool will create entryways for all levels in the input layer.

• The Input Unit Features parameter value must be a polygon feature layer or feature class that conforms to the Indoors model for the Units feature class. This tool uses the unit features to identify a facility's outer edges.

  Use the Exterior Unit Expression parameter to define which input unit features (such as patios or external stairways) will be treated as exterior to a facility. The tool identifies any doors or openings as entryways between the defined exterior unit features and interior unit features. This expression will be applied in addition to any definition query or selection on the input layer.

• The Input Door Features parameter value must be a polyline feature layer that conforms to the Indoors model for the Details feature class. The layer must have one or more door features selected.

  • If there aren't any features selected in the chosen layer, the tool will not run. Use the Select Layer By Attribute tool to make a selection.
  • This tool will identify and process different polyline feature representations of doors. This includes, but is not limited to, doors composed of single or multiple features, straight lines across an opening, curved lines representing door swings, and circular lines representing revolving doors.
  • For best results, resolve any geometry issues in the source feature class before selecting door features and running this tool. For example, remove unnecessary nodes and delete small or extraneous door features. The ArcGIS Indoors Product Data installation package includes Data Reviewer batch jobs that can help identify features to fix.

• The Buffer Size parameter defines the distance the tool will use to find entryway features along the outer edge of a building. The tool buffers inside and outside the outer edge to capture both in-swing and out-swing doors. The buffer does not need to encompass the entire door, it only needs to intersect at least one feature from it. Using a buffer that is too large may capture features within the building that are close to the outer edge but not actual entryways to the building.

• The Entryway Use Type parameter value populates the USE_TYPE field of the new entryway features.

• If you are using an indoor dataset, the z-value of the output point feature is derived from the z-value of the level on which the door is located. If you are using an Indoors geodatabase, the z-value is derived from the ELEVATION_RELATIVE field on the input door features.

• If multiple doorways are adjacent to each other, this tool may generate a single entryway point to represent them. If routing is required through each individual doorway, duplicate and manually position the generated entryway point.

• The Level ID Field parameter value is used to determine which field to populate with level ID values in the Target Entryways feature layer. If the Input Level Features parameter value is a floor-aware layer, the Level ID Field parameter will default to the layer's configured Floor Field value. Otherwise, the parameter will default to the LEVEL_ID field.

  The field set for the Level ID Field parameter must be of data type text and have a field length of 255.

• The Use Type Field parameter value is used to determine which field to populate with Entryway Use Type values for the new entryway features. By default, this will be the USE_TYPE field. If the defined field does not exist in the Target Entryways feature layer, a field with the name you supply will be created and populated with the Entryway Use Type values.

  The field set for the Use Type Field parameter must be of data type text and have a field length of 50.

Parameters

Dialog

Label	Explanation	Data Type
Input Level Features	The input polygon features representing a level or levels in one or more facilities. In the Indoors model, this will be the Levels layer. The tool processes only the levels represented by these features.	Feature Layer
Input Unit Features	The input polygon features representing building spaces. In the Indoors model, this will be the Units layer. The tool uses these features when identifying exterior edges of a facility.	Feature Layer
Input Door Features	The input polyline features representing doors. In the Indoors model, this will be a subset of features from the Details layer. The tool uses these features when identifying entryways along the exterior of a facility. Note: The layer must have one or more door features selected for the tool to run. Use the Select Layer By Attribute tool to make a selection.	Feature Layer
Target Entryways	The feature class or feature layer to which generated entryway points will be written.	Feature Layer
Buffer Size (Optional)	The distance, in meters, the tool will search inward and outward from a facility's exterior edge to identify potential entryways. The default value is 0.5 and must be greater than 0 and less than 10.	Double
Entryway Use Type (Optional)	The value used to calculate the USE_TYPE field for new entryway points. The default value is Entry.	String
Exterior Unit Expression (Optional)	An SQL expression used to define which Input Unit Features values represent a facility's exterior spaces, such as patios or fire escapes. Spaces matching this expression will be treated as exterior during entryway generation.	SQL Expression
Delete Existing Entryways (Optional)	Specifies whether existing entryway features with a USE_TYPE field value matching the Entryway Use Type parameter value will be deleted before creating new entryway points. When deleting existing entryways, the tool only identifies entryways on levels included in the Input Level Features parameter. Checked—Existing features will be deleted. Unchecked—Existing features will not be deleted. This is the default.	Boolean
Level ID Field (Optional)	The field that will be updated with the associated level ID for the new entryway features. If the Input Level Features parameter value is a floor-aware layer, this parameter will default to the layer's configured Floor Field value. Otherwise, the parameter will default to the LEVEL_ID field. If the defined field does not exist in the Target Entryways feature layer, a new field with the supplied name will be created and populated with the level ID field values.	Field
Use Type Field (Optional)	The field that will be updated with the Entryway Use Type value for the new entryway features. The default is the USE_TYPE field. If the defined field does not exist in the Target Entryways feature layer, a field with the supplied name will be created and populated with the Entryway Use Type value.	Field
