The journal Remote Sensing is offering a special issue on “Remote Sensing in Aquatic Vegetation Monitoring”. Macrophytes provide habitat and food for fish and aquatic invertebrates, and are indicators for changing environmental conditions. Ship-, air- and spaceborne remote sensing approaches can support inventory and monitoring of macrophytes. Currently, optical systems are mostly used to analyze spatial, spectral or temporal changes and deliver information on bathymetry. This special issue is now open for submission (deadline for manuscript submissions: 31 January 2021).
