Instructions for manual watershed delineation can be found in some textbooks in geography or environmental management, in government pamphlets, [4] [5] or in online video tutorials. [6] According to the US Geological Survey, there are 5 steps to manual watershed delineation: [6] Find the point of interest along a stream on the map.
In the study of image processing, a watershed is a transformation defined on a grayscale image. The name refers metaphorically to a geological watershed , or drainage divide, which separates adjacent drainage basins .
MapWindow GIS and its associated MapWinGIS ActiveX Control were originally developed by Daniel P. Ames and a team of professors and students at Utah State University in 2002-2003 as part of a research project with the Idaho National Laboratory in Idaho Falls, Idaho as a GIS mapping framework for watershed modelling tools in conjunction with source water assessments conducted by the laboratory.
The Watershed Modeling System (WMS) is a proprietary water modeling software application used to develop watershed computer simulations. The software provides tools to automate various basic and advanced delineations, calculations, and modeling processes. [ 9 ]
The pieces include units that drain to segments of streams, remnant areas, noncontributing areas, and coastal or frontal units that can include multiple watersheds draining to an ocean or large lake. Hence, half or more of the hydrologic units are not watersheds as the name of the framework Watershed Boundary Dataset (WBD) implies.
The Pfafstetter Coding System is a hierarchical method of hydrologically coding river basins.It was developed by the Brazilian engineer Otto Pfafstetter [] in 1989. [1] It is designed such that topological information is embedded in the code, which makes it easy to determine whether an event in one river basin will affect another by direct examination of their codes.
The task of simultaneously segmenting scenes from related images or video frames is termed co-segmentation, [16] which is typically used in human action localization. Unlike conventional bounding box -based object detection , human action localization methods provide finer-grained results, typically per-image segmentation masks delineating the ...
System for Automated Geoscientific Analyses (SAGA GIS) is a geographic information system (GIS) computer program, used to edit spatial data.It is free and open-source software, developed originally by a small team at the Department of Physical Geography, University of Göttingen, Germany, and is now being maintained and extended by an international developer community.
