How do we know our elephant counts are accurate? The answer is a proven scientific process, rigorous training, and careful application of technology applied consistently across all survey teams.
Survey teams for the Great Elephant Census came together before any surveys were made to discuss standards and training, and to identify ways to improve survey methods using technology.
One bit of technology the surveyors desired was a better way to keep track of flight altitude and speed. Fly too high or too fast and they are likely to under count the elephants; fly too low or too slow and there is a risk of over counting. They sought a device that would make it easier track flight speed and ensure altitude was right.
To address this need, engineers at Vulcan Inc., Paul G. Allen's company, developed and built a simple, inexpensive survey data logger to help pilots stay on track and to record the data scientists need to calculate the count post-survey.
The data logger is built from mostly off-the-shelf parts, including a consumer tablet that serves as the screen and input method. An app written by Vulcan engineers supplies the brain. Custom mounting brackets created using a 3-D printer attach the tablet to the logging unit, making the whole package able to tolerate the rough operating environment of wildlife surveys.
Six data loggers have been delivered to survey teams already, with several more on the way. Vulcan engineers and Howard Frederick, one of the survey scientists, recently met in Seattle to discuss upgrades to the data logger based on feedback from the field. Howard shared his excitement about data logger as an important tool for improving the accuracy of the Census. The entire team is dedicated to helping produce the best possible Census data.
