Installing BASINS 4.1
The BASINS installation program copies BASINS system files, tools, documentation, and models, and it also sets up BASINS icons automatically.
The BASINS installation program allows the user to install the BASINS system and associated models. The BASINS system installation program installs all of these components to the local hard drive in a fixed directory structure. It also sets up a Windows BASINS program group that includes icons for the BASINS components.
When running the installation program, follow the instructions on the screen.
| Tip: | The BASINS installation program does not copy any BASINS data (except the optional tutorial) to your hard drive. |
|---|---|
| Tip: | If you have multiple hard drives or partitioned drives, you may have only one BASINS directory in each partitioned or physical drive. |
- Note: It is recommended that the BASINS system be installed at the root of a drive. The user must have write access to the folder in which BASINS is installed. Be sure you have administrator privileges before starting the installation. Since some new system files are included in this release, you may need to restart Windows after some files have been updated before continuing with the installation.
- If you have BASINS 4.0 installed already (or a beta version of 4.1), uninstall it before installing BASINS 4.1. BASINS 4.0 project files and data will not be deleted during the uninstall process. BASINS 4.0 projects (MapWindow .mwprj files) will not open correctly in BASINS 4.1, but the map layers may be loaded into new BASINS 4.1 projects.
Version History
BASINS 4.1.1
- BASINS 4.1.1 is a maintenance release of minor fixes. It also includes updates to the URLs of downloaded datafiles. EPA went through a web server migration which means that data files are now available at a www3.epa.gov address. This release of BASINS may require the user to run BASINS As Administrator for downloads to work properly.
BASINS 4.1
- The current release of BASINS is built upon the latest stable release of the non-proprietary, open-source GIS MapWindow GIS (MapWindow website). Along with the update to the underlying GIS platform, the BASINS automatic watershed delineation tools have been updated to use TauDEM version 5 from Utah State University.
The major functionality of two utilities, GenScn and WDMUtil, have been incorporated into the BASINS user interface. BASINS 4.1 now includes DFLOW, a tool to estimate design stream flows for use in water quality studies. BASINS 4.1 is 64-bit and Windows 8 compatible.
BASINS 4.0
- The first version of BASINS to be primarily based on a non-proprietary, open-source GIS foundation. MapWindow GIS (MapWindow website) is the lightweight open-source GIS upon which BASINS 4.0 is built. While not being dependent upon any proprietary GIS platform, the core of BASINS 4.0 is designed to complement and interoperate with enterprise and full-featured GIS systems. BASINS 4.0 can import and export projects from ArcView 3.x and ArcGIS 9.x. This interoperability allows users access to features available in these systems but not BASINS 4.0. Along with the change to the underlying GIS platform, the BASINS extensions were refactored as they were ported to the new system.
