Grid Data

"Grids may contain any data that can be represented in a two-dimensional matrix.

Because grid data and image data can both be represented in two-dimensional matrices, it's important to know how they're different. The attributes that distinguish them are listed in the table below" (SSEC, 2020).

Interview with Dr. Pietro Campana

Dr. Pietro Campana studied environmental engineering with a focus on fluid dynamics, hydrology, and water resource management, before undertaking a PhD on solar irrigation systems. He is working on the water-food-energy nexus and is currently evaluating the first agrivoltaic system (a photovoltaic system that allows the combination of both electricity production and crop production on the same land to increase the land use efficiency) in Sweden. He constantly strives to work on something that can make a difference to people’s lives and finds developing tools and services that can solve water issues very exciting. He believes that to address the nexus challenges, we need novel technologies and more research and development funding.
