Utilizing GIS data to plan future work
Another task of the GIS is to measure distance
rings around the mature tree. Distances of 1 and 2 kilometers are drawn.
Ground survey results show that most progeny are found within 1 km of the
mature tree, so surveys from the ground to all accessible areas within the
1km ring are conducted. Air surveys cover the balance and extend outward,
from the 1km ring to 2 km away from the core. |

| Once the flight areas are selected, a route
that the flight will follow is drawn into the GIS. Points are then selected,
and coordinates are extracted from the database. They are uploaded
into the GPS unit for point to point navigation during the flight. When
the flight is completed track data is uploaded back to the computer, and
displayed on the map. Waypoints are collected on a separate GPS unit, sometimes
several units are used on one flight. |
