Calibrate Routes

Recalculates route measures using points.

1.    Input Route Features

The route features to be calibrated.

2.    Route Identifier Field

The field containing values that uniquely identify each route. This field can be numeric or character.

3.    Input Point Features

The point features used to calibrate the routes.

4.    Point Identifier Field

The field that identifies the route on which each calibration point is located. The values in this field match those in the route identifier field. This field can be numeric or character.

5.    Measure Field

The field containing the measure value for each calibration point. This field must be numeric.

6.    Output Route Feature Class

The feature class to be created. It can be a shapefile or a geodatabase feature class.

7.    Measure Calculation Method (optional)

Specifies how route measures will be recalculated.

1. DISTANCE—Measures will be recalculated using the shortest path distance between the calibration points. This is the default.
2. MEASURES—Measures will be recalculated using the pre-existing measure distance between the calibration points.

8.    Search Radius (optional)

Limits how far a calibration point can be from a route by specifying the distance and its unit of measure. If the units of measure are Unknown, the same units as the coordinate system of the route feature class will be used.

9.    Interpolate between calibration points (optional)

Specifies whether measure values will be interpolated between the calibration points.

1. Checked—Interpolate between the calibration points. This is the default.
2. Unchecked—Do not interpolate between the calibration points.

10. Extrapolate before calibration points (optional)

Specifies whether measure values will be extrapolated before the calibration points.

1. Checked—Extrapolate before the calibration points. This is the default.
2. Unchecked—Do not extrapolate before the calibration points.

11. Extrapolate after calibration points (optional)

Specifies whether measure values will be extrapolated after the calibration points.

1. Checked—Extrapolate after the calibration points. This is the default.
2. Unchecked—Do not extrapolate after the calibration points.

12. Ignore spatial gaps (optional)

Specifies whether spatial gaps will be ignored when recalculating the measures on disjointed routes.

1. Checked—Spatial gaps will be ignored. Measure values will be continuous for disjointed routes. This is the default.
2. Unchecked—Do not ignore spatial gaps. The measure values on disjointed routes will have gaps. The gap distance is calculated using the straight-line distance between the endpoints of the disjointed parts.

13. Include all features in the output feature class (optional)

Specifies whether route features that do not have any calibration points will be excluded from the output feature class.

1. Checked—Keep all route features in the output feature class. This is the default.
2. Unchecked—Do not keep all route features in the output feature class. Features that have no calibration points will be excluded.

14. Build index (optional)

Specifies whether an attribute index will be created for the route identifier field that is written to the Output Route Feature Class.

1. Checked—Create an attribute index. This is the default.
2. Unchecked—Do not create an attribute index.

Create Routes

Create Routes Tool, Linear Referencing Tools Toolbox

 

Create Routes

Creates routes from existing lines. The input line features that share a common identifier are merged to create a single route.

1.    Input Line Features

The features from which routes will be createdRoute Identifier Field

2.    Route Identifier Field

The field containing values that uniquely identify each route.

3.    Output Route Feature Class

The feature class to be created. It can be a shapefile or a geodatabase feature class.

4.    Measure Source

Specifies how route measures will be obtained.

1. LENGTH—The geometric length of the input features will be used to accumulate the measures. This is the default.
2. ONE_FIELD—The value stored in a single field will be used to accumulate the measures.
3. TWO_FIELDS—The values stored in both from- and to- measure fields will be used to set the measures.

5.    From-Measure Field (optional)

A field containing measure values. This field must be numeric and is required when the measure source is ONE_FIELD or TWO_FIELDS.

6.    To-Measure Field (optional)

A field containing measure values. This field must be numeric and is required when the measure source is TWO_FIELDS.

7.    Coordinate Priority (optional)

The position from which measures will be accumulated for each output route. This parameter is ignored when the measure source is TWO_FIELDS.

1. UPPER_LEFT—Measures will be accumulated from the point closest to the minimum bounding rectangle's upper left corner. This is the default.
2. LOWER_LEFT—Measures will be accumulated from the point closest to the minimum bounding rectangle's lower left corner.
3. UPPER_RIGHT—Measures will be accumulated from the point closest to the minimum bounding rectangle's upper right corner.
4. LOWER_RIGHT—Measures will be accumulated from the point closest to the minimum bounding rectangle's lower right corner.

8.    Measure Factor (optional)

A value multiplied by the measure length of each input line before they are merged to create route measures. The default is 1.

9.    Measure Offset (optional)

A value added to the route measures after the input lines have been merged to create a route. The default is 0.

10. Ignore spatial gaps (optional)

Specifies whether spatial gaps will be ignored when calculating the measures on disjointed routes. This parameter is applicable when the measure source is LENGTH or ONE_FIELD.

1. Checked—Spatial gaps will be ignored. Measure values will be continuous for disjointed routes. This is the default.
2. Unchecked—Do not ignore spatial gaps. The measure values on disjointed routes will have gaps. The gap distance is calculated using the straight-line distance between the endpoints of the disjointed parts.

11. Build index (optional)

Specifies whether an attribute index will be created for the route identifier field that is written to the output route feature class.

1. Checked—Create an attribute index. This is the default.
2. Unchecked—Do not create an attribute index. 

Dissolve Route Events

Dissolve Route Events

Removes redundant information from event tables or separates event tables having more than one descriptive attribute into individual tables.

1.    Input Event Table

The table whose rows will be aggregated.

2.    Event Table Properties

2. Event Type—The type of events in the input event table (POINT or LINE).

• POINT—Point events occur at a precise location along a route. Only a from-measure field must be specified.
