Which phrase refers to the collection of geospatial data through the use of satellite imagery?

The phrase that refers to the collection of geospatial data through the use of satellite imagery is remote sensing. This process involves obtaining information about the Earth's surface without making physical contact, primarily through the use of satellites equipped with sensors that capture images and data from a distance. Remote sensing can provide valuable information for various purposes, including environmental monitoring, urban planning, agriculture, and disaster response.

In contrast, geospatial analysis typically involves interpreting and analyzing geospatial data for various applications, while spatial mapping is more focused on the visual representation of this data in maps. Data assimilation refers to the methods used to combine different sources of data into a coherent dataset, often used in fields like meteorology or computational modeling, rather than specifically relating to the capture of data via satellite imagery.
