Sensor Platforms
Footprint and Spatial Resolution
The three most common satellite platforms for multispectral imagery are MODIS (Moderate Resolution Imaging Spectroradiometer), Landsat, and Sentinel-2.
Airborn imagery or cameras on unmanned aerial systems (Drones, UAV, UAS) have an even smaller footprint but usually a rather high spatial resolution between 2 cm and 1 m.
Temporal Aspects
The orbit time determines how frequently we will get an image at a given spot on Earth (e.g. Marburg). For MODIS, we get images at least every two days. Landsat has a temporal resolution of 16 days. Sentinel-2 consists of two satellites (2A and 2B) and therefore has a combined temporal resolution of five days.
Not only the image frequency is relevant but also the launch date of a satellite system. E.g. for long-term change analyses of the landscape, Sentinel-2 is not suitable because the first images from Sentinel-2A are from 2015. Landsat would be a better choice here. It started in 1972. MODIS in 1999.
