TopoFlow-Data-HIS

As part of the CUAHSI HIS project (http://his.cuahsi.org/), a large and growing collection of hydrologic time series data has been made available through a uniform web service called HIS Central. The HIS Central website provides a list of registered public data services and a separate information page for each service. The HIS Central web service uses WML (Watershed Markup Language) to create a single, standard interface to this diverse and distributed set of web services. A list of allowed "concept keywords" that can be used for queries can be found from this website (http://water.sdsc.edu/hiscentral/webservices/hiscentral.asmx?op=GetSearchableConcepts). A description of the WSDL interface functions can be found from this website (http://water.sdsc.edu/hiscentral/webservices/hiscentral.asmx).

Model introduction

This component lets you create a query by entering a search keyword, bounding box, start date, stop date, etc. Once data has been downloaded from the web service, it can either be saved to files or accessed directly by other components through the "Data" port, which has a standard CSDMS IRF-based interface. Note that this component must currently be used in "stand-alone/driver" mode, so that the Run button will appear.

Notes

Additional "Data" components that download data from online web services are planned for the near future including a component to download seamless USGS NED DEMs and a component to download grids and grid stacks using OpenDAP.

Examples

An example run with input parameters, BLD files, as well as a figure / movie of the output
