The TZCRC assisted in setting up an annotation lab space in Arusha, northern Tanzania, to process a database of images from RSO survey counts in Tanzania collected by TAWIRI in the past decade.

• Annotators were provided by TAWIRI - mostly MWEKA (wildlife college) and university students and graduates looking for experience in conservation biology. The Covid-19 crisis meant that setting up a lab with 8-10 annotators as initially planned was impossible, and only 6 people were able to work with the suggested distancing layout.

• Annotators were mostly domain experts on Tanzanian wildlife and/or human activity assessment. The ability to recognize large plains species was a prerequisite, and supplemental training was provided on how to identify the smaller and less common game (kudu, bushbuck). The entire TAWIRI lab team was added to a Slack channel so that people could ask questions and check species identifications - this proved to be invaluable for training data quality assessment.

• A CVAT (Computer Vision Annotation Tool) server was set up at the lab and a lab manager was trained in managing the system. Annotators were trained in the use of CVAT, and the lab manager exported each task as it was finished.
