Identification_Information Citation Citation_Information Originator: Michigan Technological University Publication_Date: 08/01/01 Title: FIA Plots Publication_Information Publication_Place: Houghton, MI Publisher: Michigan Technological University Description Abstract: This data set contains Forest Inventory and Analysis (FIA) plots. Locations are equivalent to those given in the comma delimited (csv) file provided by the Forest Service - United States Department of Agriculture. Associated attribute data contain the FIA plot level information (record type 20) also provided in the csv file from the Forest Service. The data provided by the Forest Service were downloaded from the web and processed in a database management system (DBM) and in Arc/Info to create a point coverage of the FIA plots. Purpose: The purpose is to provide a point coverage of the FIA plots in FIAMODEL. http://forestry.mtu.edu/data/fiamodel Time_Period_of_Content Time_Period_Information Range_of_Dates/Times Beginning_Date: 01/01/98 Ending_Date: ?

The accuracy reflects the content of the data offered on the web by the Forest Service. Logical_Consistency_Report: Since the plot locations are "fuzzed" by the Forest Service, some inconsistencies can occur. For example, a plot may have attribute information indicating that it is part of county "A," but it may actually show up in the adjoining county "B." Completeness_Report: Data set is complete. Reflects content of original Forest Service data. Positional_Accuracy Horizontal_Positional_Accuracy Horizontal_Positional_Accuracy_Report: The nominal horizontal accuracy is approximately 1 mile. The horizontal accuracy can be much less depending on how each state "fuzzed" the locations. In some cases the county centroid may be used when the actual location is not available. Actual plot locations can not be released.

Process_Step Process_Description: FIA data are downloaded from the web in comma delimited format. A database management system is used to calculate standing volumes, annual net growth, annual mortality, and annual removals by plot. Trees per acre by unique species and dbhclass combination is also calculated. A table with these variables and plot level attributes is exported in dbase format. A second table is exported with plot coordinates. Both tables are imported into Arc/Info. The coordinates are used to create a FIA point coverage with the generate command. Dbaseinfo is used to import the plot attributes. The attributes are joined to the FIA point coverage using joinitem. Next, the coverage is built using the build command with the point option. The projection system is defined with projectdefine. Finally, some quality control checks are performed on the coverage. Plots are checked for correctly associated attributes. Any plots that do not have attributes are deleted(extraneous plots). Process_Date: 1998 - ?
