Many regions are still threatened with frequent floods and water resource shortage problems in China. Lei, Xiaohui Wang, Yuhui Liao, Weihong Jiang, Yunzhong Tian, Yu Wang, Hao These tools easily integrate other similarly formatted data sets.ĭevelopment of efficient and cost-effective distributed hydrological modeling tool MWEasyDHM based on open-source MapWindow GIS Over 200 parameterization routines currently exist, generating information about shape, area, and topological association with other features of the same or different maps, as well many types of information based on ancillary data layers such as soil and vegetation properties. Once the spatial feature maps have been prepared, then the GIS Weasel s many parameterization routines can be used to create descriptions of each element in each of the user s created maps. The user is then able to use any combination of the GIS Weasel's tool set to create one or more maps for depicting different kinds of geographic features.
The user may define the AOI as a custom drainage area based on an interactively specified watershed outlet point, or use a previously created map. This is normally a digital elevation model, but can be the surface of a ground water table or any other data that flow direction can be resolved from. numerous flavors of Unix and Microsoft Windows).The GIS Weasel requires an input ArcInfo grid of some topographical description of the Area of Interest (AOI). The GIS Weasel will run on all platforms that Workstation ArcInfo runs (i.e. The GIS Weasel uses Workstation ArcInfo and its the Grid extension. The user does need knowledge of how the model will use the output from the GIS Weasel. The interface does not require user expertise in geographic information systems ( GIS). The GIS Weasel is a map and Graphical User Interface (GUI) driven tool that has been developed as an aid to modelers in the delineation, characterization of geographic features, and their parameterization for use in distributed or lumped parameter physical process models. The GIS weasel - An interface for the development of spatial information in modeling The general procedures used to provide input to the WEPP model and to display model output will be demonstrated. The key components and algorithms of the online GIS system will be outlined. This presentation will highlight efforts on development of a new online WEPP GIS interface, targeted toward application in forested regions bordering the Great Lakes. At present, a GIS complement with a model bank (the models build in to the GIS) and users' models (programs launched on users' PCs but receiving and displaying data via GIS) is developed.ĭevelopment of a GIS interface for WEPP Model application to Great Lakes forested watersheds Each type of data is matched to a module which allows selection and visualization of the data. According to the basic data types, the module structure of GIS was developed. Php-modules and python-scripts are used to provide data access, processing, and exchange between the client application and the server. A map service based on MapServer and MySQL data management system were chosen for the Black Sea GIS.
The software for data access and visualization was developed using client server architecture. The work aims at creating the Black Sea geoinformation system ( GIS) and complementing it with a model bank.
