Field staff collected the data using a GeoExplorer 6000 series Trimble unit on a 2 meter staff, allowing greater precision collecting elevation and horizontal data. Information regarding the culvert length, Upstream/downstream, condition, ownership, end type, restrictions, the date and the person collecting the data were recorded in the field and verified in the office. Data was collected in the field during the summer of 2014 and 2015, data Culvert length data was entered into the shapefile attribute table using ArcGIS to measure the distance between the two end-points collected in the field. Upstream and downstream designations for culverts were primarily entered in the field, for problematic (flat) culvert location flow accumulation data from ArcMAP were used to determine upstream and downstream ends of culverts. Culvert condition refers to if the pipe has been damaged or is in need of some maintenance, the attribute table provided a comment column to provide additional information regarding culvert condition or any other details pertinent to that site. The Ownership and maintenance fields provide information regarding whether the culvert is public or private and if public which entity is responsible for the culvert. The date of collection is automatically recorded by the Trimble unit and the surveyor identification is entered upon closing each file, data provided from public agencies were identified as said agency in the surveyor field.
