AUTOMATING MONITORING OF ROADSIDE WEEDS N.P. Cam', K. McKague\ L. Kingston', and S. Struger' ABSTRACT An integrated system was evaluated for monitoring of roadside weed locations and related features, incorporating global positioning systems (GPS) for locating the sites in the field and geographic information systems (GIS) for storing, managing, manipulating and displaying the data. Weed areas, desirable vegetation, water features, culverts and sensitive adjacent land use were recorded. Methods of recording various roadside features as polygon, linear or point data were explored. Two systems of collecting the information were compared - a polygon, fieldbased collection system and a linear, vehicle-based collection system. Data collected can be used for planning of roadside vegetation management operations, contract management, quality control, and for communication of vegetation features to staff involved in planning, design and construction.
