Property

Description

Target layer

Feature with point, line or polygon geometry which is used as the source of the buffer creation.

Distance by

Specifies whether a list of distances ('Distance) or the value of a certain field ('Field) is used to create the buffer.

Distances

Distance field

If Distance was chosen in the field Distance by, this field takes the values to create the buffer. This distances have to be written within squared brackets.
 
Examples:
Simple Buffer: [100]

Multiple Buffer (Creation of multiple buffer circles): [100,200,300]

Usage of decimal places: [100.5]

If Field was chosen in the field Distance by, this field specifies which attribute value is taken to create the buffer.

Unit

Specifies the linear unit for the distance values.

Dissolve type

Determines whether adjacent buffer areas should be overlapping  (falsene) or dissolved ('Dissolve). There is also an additional option called Split, which avoids overlapping by delimiting adjacent buffer areas along the imaginary center line of their overlap.

Note: Please consider that Split is only available if point geometries are used as target layer.

Buffer type

Determines the type of the buffer area. This is especially important for the calculation of multiple buffers. Rings creates separated, non-overlapping rings, while Disks creates overlapping circles.

sideType

Determines whether the feature, which is used as the source of the buffer creation, is integrated into the buffer area ('Full) or not ('Outside).

Note: Please note that the sideType Outside is only applicable to simple buffers.

Result layer name

Defines the name of the result layer, which is also displayed in the Table of Contents.

Property

Description

Target Layer

Point or polygon layer which is used as source of the hotspot calculation.

Find clusters of

Determines the numeric field in the analyzed target layer. Either a specific field is selected, or the Point Counts mode is used.

Count points within

If the target layer contains points and no specific field was selected via Find clusters of, a polygon layer can be chosen which is used as basis for the aggregation and analysis of the points. All points inside of a polygon feature are summarized to one result value.

Define where points are possible

If the target layer contains points and no specific field was selected via Find clusters of, a polygon layer can be chosen where events are possible. All points, which are not inside this polygons, are ignored.

Result layer name

Defines the name of the result layer, which is also displayed in the Table of Contents.

Property

Description

Target Layer

Point features, which are aggregated within a specific polygon.

Polygon Layer

Polygon layer in which the point features are aggregated.

Keep areas with no points

Specifies whether polygons, which contain no points, are returned.

Add Statistics

Further field specific statistical analyses can be determined for all points inside a polygon. The following statistics are provided:

•Sum - Calculates the total value of all points inside every polygon.

•Mean - Calculates the mean value of all points inside every polygon.

•Min - Returns the smallest value of all points inside every polygon.

•Max - Returns the largest value of all points inside every polygon.

•Stddev - Returns the standard deviation of all points inside every polygon.

Group by field

Specifies the field name of the point layer, which is used to group the points.

Result layer name

Defines the name of the result layer, which is also displayed in the Table of Contents.
