source
- 'from' vector map. Path to a vector layer.
enum
of ("point", "line", "boundary", "area", "centroid")
- 'from' feature type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
source
- 'to' vector map. Path to a vector layer.
enum
of ("point", "line", "boundary", "area", "centroid")
- 'to' feature type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number
- Maximum distance or -1.0 for no limit. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
number
- Minimum distance or -1.0 for no limit. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
enum
of ("cat", "dist", "to_x", "to_y", "to_along", "to_angle", "to_attr")
- 'upload': Values describing the relation between two nearest features. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
field
- Column name(s) where values specified by 'upload' option will be uploaded. The name of an existing field. ; delimited list of existing field names.
field
- Column name of nearest feature (used with upload=to_attr). The name of an existing field. ; delimited list of existing field names.
vectorDestination
- Nearest. Path for new vector layer.
vectorDestination
- Distance. Path for new vector layer.
extent
- GRASS GIS region extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used..
number
- v.in.ogr snap tolerance (-1 = no snap). A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
number
- v.in.ogr min area. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
enum
of ("auto", "point", "line", "area")
- v.out.ogr output type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
string

boolean
- Also export features without category (not labeled). Otherwise only features with category are exported. 1 for true/yes. 0 for false/no. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm()

). Default value is TRUE
.
logical specifying if parameter .quiet
for qgisprocess::qgis_run_algorithm()
Default value is TRUE
.
logical specifying if messages from qgisprocess::qgis_run_algorithm()
should be printed (TRUE
) or not (FALSE
). Default value is FALSE
.
