Buffer

Computes buffer areas for all features in an input layer using a fixed or attribute-based distance.

Inputs:

• Source file. Single file or ZIP with any OGR-compatible vector dataset.

• Buffer distance source. Where to take the buffer distance from:

  • Value;

  • Attribute;

• Buffer distance - buffer distance when Value is selected;

• Attribute name - numeric attribute containing buffer distances if Attribute is selected;

• Calculation CRS - coordinate reference system used for buffering:

  • Source layer internal CRS (Internal);

  • Optimal UTM Zone (UTM);

• Segments - number of segments used to approximate a quarter circle in rounded buffers;

• Merge overlaps - dissolve overlapping buffers. Disconnected dissolved parts are written as separate features;

• Output format - format of the output buffer dataset:

  • GeoPackage (GPKG);

  • GeoJSON (GeoJSON);

• Output CRS - coordinate reference system of the output file:

  • Source layer internal CRS (Internal);

  • WGS84 (EPSG:4326) (WGS84);

  • Pseudo Mercator (EPSG:3857) (Pseudo Mercator);

  • Optimal UTM Zone (UTM).

Outputs:

• GeoPackage file.
