Please refer to the SQL Server documentation for detailed coverage of this topic. Instructions for using BasinDelineator are integrated into the tool and accessed from the "Help" function on the startup window.Protecting Your Data Through Regular BackupsĪs the database administrator for your organization's implementation of an enterprise database in any ReliaSoft desktop application, you have the ability to perform the backups and other maintenance activities necessary to protect the information stored in the SQL Server database. BasinDelineator returns a shapefile which contains a basin polygon for each correctly specified basin pourpoint. The pourpoints must be located on the NHDPlusV2 NHDFlowline network which is defined as the subset of NHDFlowline features with known flow direction (i.e. In the second method, the user specifies a basin identifier and the latitude/longitude coordinates of the pourpoint. In the first method, the user specifies a basin identifier, an NHDFlowline reachcode, and a measure along the reach. The input pourpoints may be specified using one of two methods.
The CA3TV2 accumulation function requires one NHDPlusV2.1 Data Extension and the most recent version of the NHDPlusV2.1 Global Data:īasinDelineator delineates drainage basins for a user-defined set of basin pourpoints on the NHDPlusV2 network.
Due to a change from ArcGIS 10.1 to 10.2.2, a Windows setting must be changed in order for CA3TV2 to operate correctly. Instructions for using CA3TV2 are integrated into the tool and accessed from the "Help" function on the startup window.ĪTTENTION: Important instructions are contained in the Readme file. the subset of NHDFlowline features with NHDFlowline.Flowdir = "With Digitized"), the CA3TV2 accumulation function builds the upstream accumulated values for attributes that have been allocated to either NHDPlusV2 catchments or NHDPlusV2 NHDFlowline features. For each NHDPlusV2 NHDFlowline network feature (i.e. The CA3TV2 allocation function takes a user-supplied raster dataset of landscape attributes and allocates the attributes to the NHDPlusV2 catchments. (796 K) NHDPlusV2 Catchment Attribute Allocation and Accumulation Tool (CA3TV2)ĬA3TV2 has two main functions, an attribute allocation function and an attribute accumulation function, which may be used separately or in combination.
System Requirements: Windows 7 ArcGIS 10.1/SP 1 Use of the tool is demonstrated in training Exercise #1 found on the NHDPlusV2 Documentation page.
This tool helps users determine whether any data in their local collection has an update available. NHDPlusV2.1 data components are updated from time to time, if errors are discovered. The Check NHDPlusV2.1 Currentness tool compares a user's NHDPlusV2.1 data holdings against the data contained on the NHDPlus website and reports differences in individual data component versions. Indexes and pyramids help ArcGIS process and display NHDPlusV2.1 data faster.
The Prep NHDPlusV2.1 Data tool processes the user's local NHDPlusV2.1 data holdings and creates spatial indexes, attribute indexes, and grid pyramids. Installation of the toolbox is described in training Exercise #0 found on the NHDPlusV2 Documentation page. The toolbox currently contains two tools: Prep NHDPlusV2.1 Data and Check NHDPlusV2.1 Currentness. The NHDPlusV2 Toolbox contains geoprocessing tools specifically for use with NHDPlusV2.1 data.
