Data set has been visually inspected. All data produced strives to meet National Mapping Accuracy Standards (NMAS).
Existing public right of way sidewalks, curb ramps, and impediments and obstructions in Leon County were inventoried by Planning Department staff. Sidewalk centerlines from street segment curb to curb, curb ramps, and impediments and obstructions were then recorded by Planning Department staff with a Trimble ProXR GPS and a Trimble TDC1 datalogger. Sidewalks widths were measured with a handheld tape measure, and any necessary offsets were recorded utilizing a handheld compass and a Leica Disto Classic laser range finder. Various attribute data were collected. All feature data were uploaded to GPS Pathfinder Office, differentially corrected, converted to GIS shape files, and corrected using 2001 digital orthographic aerial photos. Supplemental_Information: 1. This is not an engineering-grade survey of sidewalks and/or related sidewalk facilities. Slopes, cross slopes, landings, and other engineering and construction variables consistent with the Americans with Disabilities Act Accessibility Guidelines were not measured or recorded. However, sidewalk widths and other condition attributes were. Impediments are considered to be any section of the sidewalk, based on the judgement of trained field personnel, that is in a comparably worse condition than surrounding sidewalk sections, which may cause difficulty for wheelchair or pedestrian passage. Impediments include light, moderate, or severe cracking, faulting, and/or surface wear. Obstructions are features which reduce the minimum clear width for single wheelchair passage of 32 inches (815 mm) at a point and 36 inches (915 mm) continuously, or they prevent wheelchair access to a sidewalk segment. 2. Sidewalk segments and other features on private roads were not mapped. 3. Since sidewalk construction and repairs, including upgrades and additions to address ADAAG, are ongoing activities of local government and the development of property, these layers cannot be considered absolutely comprehensive or complete. Please contact the appropriate local government public works department for the latest activities.
