These website tools can make it very easy to determine the surface area of your water resource.Ī pond surface area could be estimated by walking the perimeter of the pond and stopping at various waypoint locations along the pond shoreline. Geographical Information Websites: There are also geographical information programs on the internet, like Google Earth or Bing Maps, which use satellite imagery to display a map of your pond or lake.The software can connect the waypoints and calculate the area inside the resulting shape. Various locations, or "waypoints," can be stored in the GPS unit for use with mapping software that either accompanies the unit or can be purchased separately. GPS units allow you to determine your exact location on earth using multiple satellites in space. They are now routinely used for outdoor recreation (hunting, hiking, camping, etc.) and navigation. Handheld Global Positioning Systems (GPS): Handheld GPS systems have become quite common over the past five years as they have become more affordable.This method requires more measurement and effort, but the final area estimate will probably be within ±5 to 10 percent of the actual pond area. This would be most easily done during winter when the pond is frozen and the transects could be easily laid out and measured. Note that instead of horizontal transects, this method requires measurement of the distance between each vertical transect. A new trapezoid is defined anywhere the shoreline makes a rapid change in direction. Multiple Trapezoids Method: A more accurate method to determine the area of an odd-shaped pond is to divide the pond into multiple trapezoid shapes.Depending on the number of width and length measurements made, the final area will probably be within about ☒0 percent of the actual pond surface area. You can convert square feet into acres by dividing it by 43,560 ft2 per acre. If you do your measurements in feet, your result will be in square feet. The area is then calculated by multiplying the average width times the average length. The more measurements that you make, the more accurate your result will be. Make certain you get both the longest and shortest distances in calculating the average length, and the widest and narrowest distances for determining the average width.
