Noxious Weed Information System (NWIS)

Each state biologist and county will have a stand-alone copy of the database at their field sites. The field copies of the database coordinate with a central database through FTP exchanges over the Internet. A MapInfo GIS system accepts GPS positional information on weed populations and controls activities and provides maps of infestations.

The purpose of the database is to use FTP exchange and MapInfo GIS to help California field biologists inventory noxious weed infestations and track eradications. Methodology Description: The NWIS is an integrated central data clearinghouse, anchored by two database systems. One database is a public forum where governmental land managers can describe their weed control projects and look for other persons with similar concerns.

It is also intended as a source of information on weed biology and control. This system will be available through a World Wide Web site being developed at the Information Center for the Environment at University of California, Davis. The second database system is intended for weed biologists within the state and counties and will help them inventory and map infestations of noxious weeds and track eradication efforts.
