This algorithm takes a points layer and a polygon layer and counts the number of points from the first one in each polygons of the second one.

This algorithm takes a points layer and a polygon layer and counts the number of points from the first one in each polygons of the second one.

An attribute is used in the points layer to assign weights to each point.

This algorithm takes a points layer and a polygon layer and counts the number of points from the first one in each polygons of the second one.

Points are classified based on an attribute, and if several points with the same attribute value are within the extent of the polygon, only one of them is counted. The final count of point in a polygon is, therefore, the count of different classes that are found in it.

This algorithm creates a points layer, with points distributed along the lines of an input vector layer. the distance between points (measured along the line) is defined as a parameter.
