Aggregate Points 

How to use Aggregate Points Tool in ArcToolbox ArcMap ArcGIS??

Aggregate Points Tool

Aggregate Points Tool, Generalization Toolset, Cartography Toolbox

Aggregate Points

Creates polygon features around clusters of proximate point features.

1. Input Features

The input point features that will be assessed for proximity and clustering.

2. Output Feature Class

The feature class created to hold the polygons that represent the point clusters.

3. Aggregation Distance

The distance between points that will be clustered.

Aggregate Polygons 

How to use Aggregate Polygons Tool in ArcToolbox ArcMap ArcGIS??

Aggregate Polygons Tool

Aggregate Polygons Tool, Generalization Toolset, Cartography Toolbox

Aggregate Polygons

Combines polygons within a specified distance of each other into new polygons.

1. Input Features

The polygon features to be aggregated. If this is a layer referencing a representation and shape overrides are present on the input features, the overridden shapes, not the feature shapes, will be considered in aggregation processing.

2. Output Feature Class

The output feature class to be created.

3. Aggregation Distance

The distance to be satisfied between polygon boundaries for aggregation to happen. A distance must be specified, and it must be greater than zero. You can choose a preferred unit; the default is the feature unit.

4. Minimum Area (optional)

The minimum area for an aggregated polygon to be retained. The default value is zero, that is, to keep all polygons. You can specify a preferred unit; the default is the feature unit.

5. Minimum Hole Size (optional)

The minimum size of a polygon hole to be retained. The default value is zero, that is, to keep all polygon holes. You can specify a preferred unit; the default is the feature unit.

6. Preserve orthogonal shape (optional)

Specifies the characteristic of the output features when constructing the aggregated boundaries.

1. Unchecked--Organically shaped output features will be created. This is suitable for natural features, such as vegetation or soil polygons. This is the default.
2. Checked--Orthogonally shaped output features will be created. This option is suitable for preserving the geometric characteristic of anthropogenic input features, such as building footprints.

7. Barrier Features (optional)

The layers containing the line or polygon features that are aggregation barriers for input features. Features will not be aggregated across barrier features. Barrier features that are in geometric conflict with input features will be ignored.

8. Output Table (optional)

A one-to-many relationship table that links the aggregated polygons to their source polygon features. This table contains two fields, OUTPUT_FID and INPUT_FID, storing the aggregated feature IDs and their source feature IDs, respectively. Use this table to derive necessary attributes for the output features from their source features. The default name for this table is the name of the output feature class, appended with _tbl. The default path is the same as the output feature class. No table is created when this parameter is left blank.

Collapse Dual Lines To Centerline 

How to use Collapse Dual Lines To Centerline Tool in ArcToolbox ArcMap ArcGIS??

Collapse Dual Lines To Centerline Tool

Collapse Dual Lines To Centerline Tool, Generalization Toolset, Cartography Toolbox

Collapse Dual Lines To Centerline

Derives centerlines from dual-line (or double-line) features, such as road casings, based on specified width tolerances.

1. Input Features

The input dual-line features, such as road casings, from which centerlines are derived.

2. Output Feature Class

The output feature class to be created.

3. Maximum Width

Sets the maximum width of the dual-line features to derive centerline. A value must be specified, and it must be greater than zero. You can choose a preferred unit; the default is the feature unit.

4. Minimum Width (optional)

Sets the minimum width of the dual-line features to derive centerline. The minimum width must be greater than or equal to zero, and it must be less than the maximum width. The default value is zero. You can specify a preferred unit; the default is the feature unit.
