The area between isohyets may then be measured with a digitizer or a planimeter
, and the average rainfall determined by using Equation 3.
Because we were using a planimeter
to establish area values for various land use/land cover from the SCS photos, any property less than two acres in size was eliminated from the analysis due to the limits of the planimeter
's accuracy and the scale of the aerial photographs.
So we measured initial and fin al gallery widths with digital calipers, measured the lengths with a digital planimeter
after tracing the galleries on clear mylar, and estimated gallery size as the area of a trapezoid of these dimensions.
We used a planimeter
within the geographic information system to determine habitat availabilities in the General Land Office Sections.
Motherworm size was determined by drawing the worm's outline with a camera lucida and measuring this area with a planimeter
The extent of the impact on wetland features was then measured, usually with a planimeter
Areas were measured on the base map using a Keuffel and Esser Polar Planimeter
and were converted into [km.
To measure continent size, they traced around the perimeter of the landmasses with an electronic planimeter
, a device that measures area.
The proportion of adhesive contact areas to those of no contact can be calculated with a compensating polar planimeter
In addition to automatically recording waypoints at pre-set intervals, MobileMapper saves time by calculating polygon areas, thus saving on the need to calculate areas separately with a planimeter
Leaf area was also analyzed using an optical electronic planimeter
(LI -COR[R]--LI 3100), by randomly collecting four plants in each treatment.
The areas of pressed sample and water were measured using a planimeter
