NOTE: This tool only works with an ArcInfo license and will only be available in ArcToolbox if you have installed ArcInfo Workstation.


Combines an unlimited number of coverages into a single coverage.

Append checks for the existence of the coverage, verifies that the list of feature attribute table items matches the items in previously entered coverages (unless the FEATURES_ONLY option is used), and calculates Tic-ID and feature User-ID offsets according to the specified offset option.

Usage tips

Command line syntax
An overview of the Command Line window
Append_arc <in_covers;in_covers...> <out_cover> {FEATURES_ONLY | FEATURES_ATTRIBUTES} {POLY | LINE | POINT | NODE | NET | LINK | ANNO.subclass | SECTION.subclass | ROUTE.subclass | REGION.subclass} {NO | TICS_ONLY | FEATURES_ONLY | FEATURES_TICS}

Parameter Explanation Data Type
<in_covers;in_covers...>

The Input Coverages to be appended. There is no limit to the number of coverages that can be entered.

Coverage; Coverage...
<out_cover>

The Output Coverage to be created. The Output Coverage cannot already exist.

Coverage
{FEATURES_ONLY | FEATURES_ATTRIBUTES}

Determines whether only coordinates will be appended (FEATURES_ONLY) or whether features will also be appended.

  • FEATURES_ONLY — Location information for all feature classes that are appended. Feature attribute tables are not appended.
  • FEATURES_ATTRIBUTES — The features in the specified coverage define the set of features to be appended.

String
{POLY | LINE | POINT | NODE | NET | LINK | ANNO.subclass | SECTION.subclass | ROUTE.subclass | REGION.subclass}

The feature class of the input coverage or coverages.

  • POLY — Polygon feature coordinates and attributes are appended including label points.
  • LINE — Arc feature coordinates and attributes are appended.
  • POINT — Point feature coordinates and attributes are appended.
  • NODE — Arc and node feature coordinates and their attributes are appended.
  • NET — Arc and polygon feature coordinates and their attributes are appended.
  • LINK — Arc and point feature coordinates and their attributes are appended.
  • ANNO.subclass — Annotation features and attributes of the subclass are appended.
  • SECTION.subclass — Section feature coordinates and attributes of the subclass are appended.
  • ROUTE.subclass — Route and section feature coordinates and attributes of the subclass are appended.
  • REGION.subclass — Region feature coordinates and attributes of the subclass are appended. Polygon feature coordinates and attributes are also appended.
The Add Value button, which is used only in ModelBuilder, allows you to add expected value(s) so you can complete the dialog box and continue to build your model.

String
{NO | TICS_ONLY | FEATURES_ONLY | FEATURES_TICS}

Specifies how tics and coverage features will be numbered in the Output Coverage. IDs can be offset to ensure unique ID values for Output Coverage features. The ID offset is equal to 1 plus the highest ID value in the previously appended coverages. Offsets can be calculated for the following types of IDs:

  • NO — Neither Tic-IDs nor feature User-IDs will be modified. This is the default option.
  • TICS_ONLY — ID offsets will be calculated for tics.
  • FEATURES_ONLY — User-ID offsets will be calculated for the feature class(es) specified by the feature classes argument. Tic-IDs are not modified.
  • FEATURES_TICS — ID offsets will be calculated for both tics and features.

Append_arc (in_covers, out_cover, append_method, feature_classes, number_method)

Parameter Explanation Data Type
in_covers (Required)

The Input Coverages to be appended. There is no limit to the number of coverages that can be entered.

Coverage; Coverage...
out_cover (Required)

The Output Coverage to be created. The Output Coverage cannot already exist.

Coverage
append_method (Optional)

Determines whether only coordinates will be appended (FEATURES_ONLY) or whether features will also be appended.

  • FEATURES_ONLY — Location information for all feature classes that are appended. Feature attribute tables are not appended.
  • FEATURES_ATTRIBUTES — The features in the specified coverage define the set of features to be appended.

String
feature_classes (Optional)

The feature class of the input coverage or coverages.

  • POLY — Polygon feature coordinates and attributes are appended including label points.
  • LINE — Arc feature coordinates and attributes are appended.
  • POINT — Point feature coordinates and attributes are appended.
  • NODE — Arc and node feature coordinates and their attributes are appended.
  • NET — Arc and polygon feature coordinates and their attributes are appended.
  • LINK — Arc and point feature coordinates and their attributes are appended.
  • ANNO.subclass — Annotation features and attributes of the subclass are appended.
  • SECTION.subclass — Section feature coordinates and attributes of the subclass are appended.
  • ROUTE.subclass — Route and section feature coordinates and attributes of the subclass are appended.
  • REGION.subclass — Region feature coordinates and attributes of the subclass are appended. Polygon feature coordinates and attributes are also appended.
The Add Value button, which is used only in ModelBuilder, allows you to add expected value(s) so you can complete the dialog box and continue to build your model.

String
number_method (Optional)

Specifies how tics and coverage features will be numbered in the Output Coverage. IDs can be offset to ensure unique ID values for Output Coverage features. The ID offset is equal to 1 plus the highest ID value in the previously appended coverages. Offsets can be calculated for the following types of IDs:

  • NO — Neither Tic-IDs nor feature User-IDs will be modified. This is the default option.
  • TICS_ONLY — ID offsets will be calculated for tics.
  • FEATURES_ONLY — User-ID offsets will be calculated for the feature class(es) specified by the feature classes argument. Tic-IDs are not modified.
  • FEATURES_TICS — ID offsets will be calculated for both tics and features.
