How It Works
The Elephant Survey System (or ESS for short) is a suite of open source software and hardware that can be used in aerial surveys of elephants.
Aerial surveying is a key tool for effective wildlife management. However the high costs associated with large-scale surveys means that this tool is often underutilised. We believe that computer vision can be used to dramatically decrease the costs associated with surveying, while at the same time improving the consistency of results.
Features
Compared to traditional manual surveys, ESS surveys are :
Dramatically Cheaper
Direct personnel requirements in the field are reduced from 4 to 1, while surveying rate is more than doubled. This has knock-on effects on the number of support staff required, the size of the required aircraft and the amount of fuel consumed.
More Precise
Using machine vision as the primary detection mechanism reduces the component of variation in the counts that is due to experience or fatigue-level variations amongst crew members.
Auditable
More Broadly Useful
The imagery that is collected represents a rich data source that may be repurposed afterward for other scientific studies on spatio-temporal variation in vegetation, species distribution (for any species that can be identified in the photos), water levels, game paths etc.
Continuous Improvement
As more training data is gathered and machine vision algorithms improve dramatically from one year to the next, the system continues to improve. Even surveys that were conducted in the past may be reprocessed when our detection abilities improve, providing improved accuracy after-the-fact. Alternatively, newer surveys can be processed with older neural networks to provide counts that are directly comparable to older data in order to spot trends more cleanly.

Data
Over the last 6 years we have compiled a large set of data that consists of 2101 images of African bush elephants in their natural habitats.
Documentation
Take a look through our repository for all documentation relating to ESS.
Field Tests
The ESS has been regularly tested in real-life conditions with 10 separate campaigns in numerous environments.
Hardware
Our hardware is designed to maximize affordability and has proven to be extremely reliable in real African bush conditions.
Software
The ESS Software suite consists of two main components, the TriCap application and the main ESS application.
Why ESS
We believe that computer vision can be used to dramatically decrease the costs associated with surveying and improve the consistency of results.
