Major features

• Allows FVS to get initial stand and tree level data from ODBC-supported data bases.

• FVS predictions can be directly loaded into data bases.

• Allows SQL commands to execute on data bases during an FVS simulation, one or more times during any one or all cycles.

Major features - continued

• Event Monitor variables and their values can be loaded into a data base during a simulation.

• Data from the data base can define FVS Event Monitor variables during a simulation.

• Capabilities for Suppose to directly interact with data bases are being built and will be introduced in a pending release of Suppose.

Summary:

• FVS interacts with the data bases providing many of the benefits data bases provide to FVS users.

• Technical issues remain for taking advantage of these technologies within our organizations. Some of these issues will be discussed in the following papers.

Future data sources:

• Field-sampled data is expensive to collect.

• We will hear two presentations on imputation-based methods that address this issue.

• Following the presentations, we will take questions from the floor!
