I'm trying to use MGET to generate a series of current vectors (at only 3 points) that are weekly averages over a 5 year time span. I managed to generate a test case of one set of quiver arrows. I wanted to use the intersect tools to find the correspondence with geographic regions (defined as polygons) where I already know species presence or absence that same week. When I try to do this, however, I get a table with no data even though I can see visually that the arrow intersects one of my polygons. Am I doing something incorrect or is what I'm trying to do not possible with MGET generated quivers? If not, does MGET have a tool to convert the u and v current vectors into a new geographic point location defining the endpoint of the vector as a lat/lon coordinate?

For reference, you met me when I took your tutorial course in Portugal. I was the outside American student.
