Detect Feature Changes

Finds where the update line features spatially match the base line features and detects spatial changes, attribute changes, or both, as well as no change, and creates an output feature class containing matched update features with information about their changes, unmatched update features, and unmatched base features.

1.    Update Features

Line features to compare to the base features.

2.    Base Features

Line features to be compared with update features for change detection.

3.    Output Feature Class

Output line feature class with change information. The output contains all participating update features (matched and unmatched) and any unmatched base features.

4.    Search Distance

The distance used to search for match candidates. A distance must be specified and it must be greater than zero. You can choose a preferred unit; the default is the feature unit.

5.    Match Fields (optional)

Lists of fields from update and base features. If specified, each pair of fields are checked for match candidates to help determine the right match.

6.    Output Match Table (optional)

The output table containing complete feature matching information.

7.    Change Tolerance (optional)

The distance used to determine if there is a spatial change. All matched update features and base features are checked against this tolerance. If any portions of update or base features fall outside the zone around the matched feature, it is considered a spatial change. A distance can be equal to or greater than zero. The default is 0. When a value greater than zero is specified, the output will include the LEN_PCT and LEN_ABS fields. You can choose a preferred unit; the default is the feature unit.

8.    Compare Fields (optional)

Fields to determine if there is an attribute change between matched update and base features.

9.    Compare line direction (optional)

Specifies whether or not to compare line directions for matched features.

  1. Unchecked—Line directions will not be compared for matched features. This is the default.
  2. Checked—Line directions will be compared for matched features.

Feature Compare

Compares two feature classes or layers and returns the comparison results.

1.    Input Base Features

The Input Base Features are compared with the Input Test Features. Input Base Features refers to data that you have declared valid. This base data has the correct geometry definitions, field definitions, and spatial reference.

2.    Input Test Features

The Input Test Features are compared against the Input Base Features. Input Test Features refers to data that you have made changes to by editing or compiling new features.

3.    Sort Field

The field or fields used to sort records in the Input Base Features and the Input Test Features. The records are sorted in ascending order. Sorting by a common field in both the Input Base Features and the Input Test Features ensures that you are comparing the same row from each input dataset.

4.    Compare Type (optional)

The comparison type. The default is All, which will compare all properties of the features being compared.

  1. ALL—All properties of the feature classes will be compared. This is the default.
  2. GEOMETRY_ONLY—Only the geometries of the feature classes will be compared.
  3. ATTRIBUTES_ONLY—Only the attributes and their values will be compared.
  4. SCHEMA_ONLY—Only the schema of the feature classes will be compared.
  5. SPATIAL_REFERENCE_ONLY—Only the spatial references of the two feature classes will be compared.

5.    Ignore Options (optional)

These properties will not be compared.

  1. IGNORE_M—Do not compare measure properties.
  2. IGNORE_Z—Do not compare elevation properties.
  3. IGNORE_POINTID—Do not compare point ID properties.
  4. IGNORE_EXTENSION_PROPERTIES—Do not compare extension properties.
  5. IGNORE_SUBTYPES—Do not compare subtypes.
  6. IGNORE_RELATIONSHIPCLASSES—Do not compare relationship classes.
  7. IGNORE_REPRESENTATIONCLASSES—Do not compare representation classes.
  8. IGNORE_FIELDALIAS—Do not compare field aliases.

6.    XY Tolerance (optional)

The distance that determines the range in which features are considered equal. To minimize error, the value you choose for the compare tolerance should be as small as possible. By default, the compare tolerance is the XY tolerance of the input base features.

7.    M Tolerance (optional)

The measure tolerance is the minimum distance between measures before they are considered equal.

8.    Z Tolerance (optional)

The Z Tolerance is the minimum distance between z coordinates before they are considered equal.

9.    Attribute Tolerance (optional)

The numeric value that determines the range in which attribute values are considered equal. This only applies to numeric field types.

10. Omit Fields (optional)

The field or fields that will be omitted during comparison. The field definitions and the tabular values for these fields will be ignored.

11. Continue Comparison (optional)

Indicates whether to compare all properties after encountering the first mismatch.

  1. Unchecked—Stops after encountering the first mismatch. This is the default.
  2. Checked—Compares other properties after encountering the first mismatch.

12. Output Compare File (optional)

This file will contain all similarities and differences between the Input Base Features and the Input Test Features. This file is a comma-delimited text file that can be viewed and used as a table in ArcGIS.

This file will contain all similarities and differences between the in_base_features and the in_test_features. This file is a comma-delimited text file that can be viewed and used as a table in ArcGIS.

File Compare

Compares two files and returns the comparison results.

1.    Input Base File

The Input Base File is compared with the Input Test File. The Input Base File refers to a file that you have declared valid. This base file has the correct content and information.

2.    Input Test File

The Input Test File is compared against the Input Base File. The Input Test File refers to a file that you have made changes to by editing or compiling new information.

3.    File Type (optional)

The type of files being compared.

  1. ASCII —Compare using ASCII characters. This is the default.
  2. BINARY —Perform a binary compare.

4.    Continue Comparison (optional)

Indicates whether to compare all properties after encountering the first mismatch.

  1. Unchecked—Stops after encountering the first mismatch. This is the default.
  2. Checked—Compares other properties after encountering the first mismatch.

5.    Output Compare File (optional)

This file will contain all similarities and differences between the Input Base File and the Input Test File. This file is a comma-delimited text file which can be viewed and used as a table in ArcGIS.
