Process step:
Dept of Ag exported GPS waypoints to shapefile format using ExpertGPS monthly during June, July, August of 2005 and 2006.

FWP merged shapefiles into one feature class, cleaned up species misspellings, and joined additional fields from the FWP Lands tabular database.
Process date: 11/01/2007
Process step: Repeated process for 2007 collected data.
Process date: 02/22/2008
Process step: Repeated process for 2008 collected data.
Process date: 04/2009
Process step:
NOTE: The LAT LON data were uploaded into a tabular database from data collected with Garmin handheld GPS units by MT Dept of Agriculture interns. GPS data were exported from the GPS units to text files with DNR Garmin. The tabular edit/entry screen provides a button for interns to upload their GPS text files and allows them to populate all the associated weed information for the locations.

1. Created event theme for 2009 based on values in the LAT LON fields in the 2009 tabular FAS Weeds Inventory database.
2. Exported the 2009 points using the Data Frame's coordinate system.
3. Populated the GIS_Comments, PublicName, LandsName, WebSiteID. and GIS_ObjectID fields.
