Create Buffers

Create Buffers refer to create buffer polygons around input features to a specified distance.  The specified distance refers to the buffer radius, it can be a fixed numeric value or can be a numeric type of field.

iServer supports to create buffers for two-dimensional point, line and region datasets. The third column of the following pictures shows the results when setting the dissolve field.

Point dataset:

               Point                        Point Buffer          Set the Dissolve Field

Line dataset:

               Line                         Line Buffer             Set the Dissolve Field

Region dataset:

               Region                   Region Buffer           Set the Dissolve Field

Parameters for creating a buffer analysis task:

Source dataset: used to specify the dataset to be buffered, required. The buffers resource page in iServer automatically lists all the datasets that  meet the analysis conditions.

Analysis bounds: optional. Defaults to the full extent of the input dataset.

Buffer distance: optional. Defaults to 10.

Buffer distance field: optional. If this parameter is set, the above buffer distance is invalid.

Distance unit: defaults to Meter. Options values: Meter, Kilometer, Yard, Foot, Mile.

Dissolve field: optional. Used to dissolve the result buffer regions based on the specified field.
