MedWet Database (MWD) is a computer program created to enter, store and analyze data recorded using the methodology for wetland inventory. This software mimics the inventory datasheets. All the data categories have corresponding fields in the MedWet Database. It permits storage of data in DBF files, so that they can be easily imported and exported to and from other database software. The MWD is distributed with the User's Manual, which explains how to make the best use of this computer program.
