This dataset was created by merging multiple datasets together. Below is the original information for individual datasets.The septic tank and dosing system points within this dataset are part of the sewer system at Little Bighorn Battlefield National Monument (LIBI). The coordinates for this dataset were collected using a Trimble ProXR GPS receiver. This dataset was updated in August of 2009. Updates were informed by LIBI staff members. Editing was done by NPS Intermountain Region Geographic Resources Program staff. Updates included separating data from a previous dataset as well as this dataset. See Process Steps for details.The valve features were digitized from blueprints. The Little Bighorn Battlefield National Monument (LIBI) GIS program was created from academic research and coursework in the Department of Economics and Geography, United States Air Force Academy (USAFA). The GIS data developed for LIBI was complied from hardcopy maps and blueprints provided by the LIBI staff and softcopy data available from the US Census Bureau. This dataset captures the shutoff valves and drains as marked on the Power Telephone and Gas Blueprint #381/80002D sheet 5 of 5. This dataset was provided to the staff of LIBI and the Intermountain Region GIS Program Office, National Park Service free of charge, for their appropriate use. This dataset was updated in August of 2009 to capture the most current valves at LIBI. This dataset was updated using institutional knowledge via reference drawings and verbal information provided by LIBI staff members. Edits were done by NPS Intermountain Region Geographic Resources Program staff. Valves were originally features within the 'libi_valves' and 'libi_hydrants' coverage files. Updates included merging individual features of the original datasets, addition of previously missing valves, removal of valves, location changes of valves and inclusions of attribute data. See Process Steps for details.The 'underground water access' and 'water valve/inspection' features were GPS collected with a Trimble GeoXT receiver on September 14, 2010.
