Abstract

In this paper, we present the design process of a system to support agrometeorologists to improve a tiresome task of extracting data to generate time series from multiple satellite images. To understand the difficulty of dealing with thousands of images, one researcher in HCI has worked in a team of agrometeorologists for over 6 months. This case study describes the experience of this researcher using a manual and semi-automatic method developed by agrometeorologists. Moreover, we highlight the difficulties faced by specialists trying to learn how to develop scripts in order to make their tasks easier. Finally, we report the involvement of these experts in the design process of a new system that led to a more successful approach to deal with the challenge of handling enormous amount of satellite images.
