Aggregate Points and Polygons, Collapse Dual Lines To Centerline Tools
Aggregate Points

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

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.
- Unchecked--Organically shaped output features will be created. This is suitable for natural features, such as vegetation or soil polygons. This is the default.
- 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.
