DATA DELIVERY TOOLS

To transfer the technology to the client, an interactive dynamic report generator called Mississippi Forest Monitoring and Information System (MSFMIS) dynamic report generator was developed. The program can derive reports from an inventory database stored on a public server, or optionally on a locally stored inventory database. The program allows the user to select a reporting area on a county group basis (Figure 3), or as an irregular polygon (Figure 4), and a report type.  After a report type is selected, the interface presents to the user changes to match the selected report type. The user can then select the desired stand and tree criteria appropriate for the report (species groups, forest types, land ownerships, size classes, products, and others).  A version of the program can be downloaded from the web site www.fwrc.msstate.edu/software.asp.  To maintain compatibility with previous FIA databases, and have an interface that is familiar to potential clients, the FIA codes and names were adopted for the study.

Currently, the MSFMIS produces stand and stock tables, acreage tables, regeneration acreage, and productive potential stand and stock tabular reports by the selected criteria. Other dynamic link library (dll) report modules will be added as needed.

          All the inventory codes, user interface settings, GIS files, file locations, and other locale specific settings reside in external files or the system registry. This externalization of locale specific settings allows the program to be adapted to another region by simply modifying the external settings. No changes in the source code of the program are required.

An interactive web-based data delivery system was created using the FIA data standards. Developed in Microsoft Windows interface format, the data delivery system is designed to provide forest resource data on a county or regional level (Figure 3).  All information from the field plots is entered into a database and summarized depending on the user’s needs.  Irregular polygons or county boundaries can be used to define an interest area. Embedded in this system are routines that generate stand and stock tables (per acre and total values are given) with the associated precision statistics for the area and volume estimates.

The four report dynamic link libraries to be included with the release version of MSFMIS will allow the client to derive virtually any volume, acreage, reproduction, or growth estimates showing point and reliability statistics. For reports types that are needed on a continuing basis, custom programming will be added to make the report’s generation a one step process. The report generation, and data base application interfaces (APIs) will be published so clients can customize the generated reports to suit their needs.
