This is chapter 3 of the State of Environmental Science in Svalbard (SESS) report 2021. Three actions are required to improve terrestrial photography applications in Svalbard, according to the SESS report recommendations. The first one is focused on maintaining the dataset on terrestrial photography applications in Svalbard, widening the range of involved disciplines. The second one is aimed at defining a harmonised protocol based on established experience and describing guidelines for developing novel applications with a network perspective. Finally, exploring integration with remotely sensed data, it is possible to highlight potential ways of solving multi-scale gaps by combining ground based and remotely sensed data. This novel knowledge highlights even more the need for a strategic network of terrestrial cameras located in key locations where different disciplines could benefit from the description of snow cover evolution during the melting seasons.
