How it maps to the operation
| Operation parameter | Parameter here | Note |
|---|---|---|
layer | ainput | Not stated |
mask | binput | Not stated |
output | output | Not stated |
predicate | operator | intersects = intersects; within = within; contains = contains; touches = touches; crosses = crosses; overlaps = overlap; disjoint = disjoint |
Differences from the operation
- The default operator is overlap (GRASS's own test); intersects, within and the other GEOS predicates need GRASS built with GEOS.
