Use "AND" not "OR". OR=Union, that is combining all features of both vectors AND=Intersection, that is, just areas or lines covered by both vectors
Micha, That's correct, and 'AND' will exclude those portions of the drainage basins that extend past the property boundary. That's why I used 'OR' to get all points within both the basins and the property. Two extremes. :-) What I'd like to do is select only those basins that intersect the property, but all of those basins, and get rid of the other 4200+ basins that are irrelevant to the analyses. I seem to have issues with client- and agency-provided data on my projects. But, once I successfully make the data available to grass and define the appropriate computational and display regions, the modeling goes more smoothly.
