Description: This feature class contains detailed trail surface information such as trail setting, trail type, trail width, trail composition, erosional features, use, % slope, classification and maintenance features/recommendations. The trail is broken into small sections based on the above attribution. A change to any one of the attributes listed above results in closing out and starting a new feature. For instance, if a section of trail changes from 5 feet wide to 8 feet, the 5 foot section is closed out and a new feature is created and attributed with the 8 foot width.Since many small trail features make up an entire trail, segment and trail ID's have be created to aid in generalizing each trail. Trails are also broken up into segments. Trails are segmented to capture major trail type and surface changes. For instance, if the initial section of a trail is generally within a flood control channel and then comes out into a natural setting, the trail would be segmented in order to segregate that initial section of trail as flood control channel. All data was collected using a Trimble GeoExplorer 6000 GPS receiver. Data was post processed using the Differential Correction utility in Trimble's Pathfinder Office software. Horizontal accuracy percentages for processed data are as follows.5 to 15cm - 55%15 to 30cm - 5%15 to 30cm - 20%.5 to 1m - 17%1 to 2m - 3%Linear sufface data was further post processed to align with LARIAC Imagery.

Description: Data points in this feature class relate to trail access, trail amenities, cultural artifacts, safty issues, signage, surface conditions, user created trails, and drainage. These features are broken out using subtypes. All points are linked to specific trails through their segment and trail ID.All data points were collected using a Trimble GeoExplorer 6000 GPS receiver.
