The data represents Colorado noxious weed categories A, B, and C as distributed along Colorado Department of Transportation (CDOT) highways. Weeds were collected in 2009 and 2010 by EcoPlan, using handheld GPS units while riding along in a vehicle. Weed patches are represented by linear features.
Data were collected and mapped to facilitate control of noxious weeds by CDOT along highways and interstates within its jurisdiction.

Data were collected in the field by a survey crew consisting of two persons (driver + mapper). Field data were collected using Trimble GeoXH GPS units, utilizing TerraSync software. Field data (rover) files were downloaded on a daily basis using GPS Pathfinder Office version 4.10 and uncorrected data (.ssf) files transmitted to the project manager (PM) via e-mail. PM reviewed all filies in Pathfinder for completeness and logical consisitency. Data files were differentially corrected using the nearest available base station, resulting in corrected (.cor) data files. Corrected data files were exported to ESRI shapefiles and compiled into a geodatabase in ArcMap version 9.3.

In instances here CDOT right-of-way (ROW) boundaries could not be determined in the field, "unknown" was entered in the "ROW_Width" attribute.
The following attribute values were visually estimated in the field: "ROW_Width", "PW_Cover", "PW_Contain", "Second_Cover", "SW_Contain", and "Buff_Dist"
Some polylines are shorter than actual distribution of weeds due to traffic safety/logistical constraints (i.e., inability to back up safely or safely reach the start of some weed patches due to traffic and/or roadway conditions). Some polylines cross roadways in areas where weed patches continue from outside to inside shoulders (or vice versa) on on/off ramp areas.
For Category B and C noxious weeds, only patches approximately 10 feet by 10 feet in dimension or larger were mapped. For Category A noxious weeds, all weed patches were mapped, including those less than 10 feet by 10 feet in dimension.
Data were collected using Trimble GeoXH GPS units to achieve submeter accuracy. Average horizontal precision achieved over all mapped features was 0.5 meters.
