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.
·
DISTANCE—Measures will be recalculated using the shortest path
distance between the calibration points. This is the default.
·
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.
·
Checked—Interpolate between the calibration points. This is the
default.
·
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.
·
Checked—Extrapolate before the calibration points. This is the
default.
·
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.
·
Checked—Extrapolate after the calibration points. This is the
default.
·
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.
·
Checked—Spatial gaps will be ignored. Measure values will be
continuous for disjointed routes. This is the default.
·
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.
·
Checked—Keep all route features in the output feature class. This
is the default.
·
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.
·
Checked—Create an attribute index. This is the default.
·
Unchecked—Do not create an attribute index.

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 created
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.
·
LENGTH—The geometric length of the input features will be used to
accumulate the measures. This is the default.
·
ONE_FIELD—The value stored in a single field will be used to
accumulate the measures.
·
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.
·
UPPER_LEFT—Measures will be accumulated from the point closest to
the minimum bounding rectangle's upper left corner. This is the default.
·
LOWER_LEFT—Measures will be accumulated from the point closest to
the minimum bounding rectangle's lower left corner.
·
UPPER_RIGHT—Measures will be accumulated from the point closest to
the minimum bounding rectangle's upper right corner.
·
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.
·
Checked—Spatial gaps will be ignored. Measure values will be
continuous for disjointed routes. This is the default.
·
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.
·
Checked—Create an attribute index. This is the default.
· Unchecked—Do not create an attribute index.
