Special Issue "Mapping and Monitoring of Wetlands"
Deadline for manuscript submissions: closed (30 November 2021) | Viewed by 3626
Wetlands are key hubs for biological production and biodiversity, regulating both the water cycle and biogeochemical cycles. The mapping and monitoring of wetlands can be done using remote sensing imagery, terrain data, and/or hydrological modeling. On a detailed scale, high-resolution datasets (<5 m), mainly from LiDAR and optical sensors, are often used for local wetland studies, including textural and object-based image analysis which require iterative calibration and validation. Medium-resolution datasets (~5–200 m), including terrain, optical, thermal, and microwave (SAR) data, have been applied for digital wetland mapping since the 1970s. At this scale, wetlands often act as transitory ecotones and are usually classified in a pixel-wise manner. Most efforts have been directed towards estimating different wetland attributes, rather than delineating wetlands as such. A few attributes (e.g., open water and terrain forms) can be mapped using automated algorithms, even at a global scale. Mapping wetland categories across larger regions is more difficult, and the few hitherto efforts have required extensive user interactions. At a coarser scale, additional datasets from microwave brightness temperature and gravity sensors are available. Routinely monitored properties at this scale include climate, geomorphology, freeze/thaw, soil moisture, inundation, land cover, and vegetation and its phenology. These are often downscaled to support local studies, and are more seldom used for direct mapping and monitoring of wetlands over large regions. Thus, despite an explosive growth in sensors and data availability, combined with strong developments in algorithms, there are gaps in the knowledge about the extent and function of wetlands at different scales. New approaches and ideas for mapping and monitoring wetlands across space and time are needed—ideally using methods that are transparent to wetland functional traits and can be used for understanding the effects on wetlands in times of change.Dr. Thomas Gumbricht
Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
