  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. Unable to find the precise location of the offset coordinates since direction not provided; georeferenced to the land adjacent to the approximate geographic center of waterfall Cachoeira Porteira, nearby road BR-163 in Porteira, Oriximiná, ensuring that the uncertainty radius extends to encompass the 1 km. offset in the locality description. Referred to map "Figure 1: Location map of two sites of archaeological black earth (ABD) investigated at Cachoeira-Porteira, Lower Amazon region" provided by "The ceramic artifacts in archaeological black earth (terra preta) from Lower Amazon region, Brazil: chemistry and geochemical evolution" article for location information for Cachoeira Porteira (Lima da Costa, Marcondes, et al. "The ceramic artifacts in archaeological black earth (terra preta) from Lower Amazon region, Brazil: chemistry and geochemical evolution" (2004) accessed 24 October 2013). The reference map shows that the approximate location of the waterfall is at the junction of Rio Trombetas and Rio Mapuera and very nearby a main road. Using the reference map and Google Maps - Satellite View, located Cachoeira Porteira. Used Canadensys Lat/Long Crosshairs to find the coordinates of the land adjacent to the approximate geographic center of the waterfall. Used Distance Measurement Tool (Google Maps) to find linear extent by measuring from the selected coordinates to the farthest extent of the confluence of the rivers. Input coordinates, linear extent (1416.42 m.), measurement error (.01 m), offset distance (1000 m.), and distance precision (100 m.) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to Georeferencing Quick Reference Guide, Offset: Offset only, no direction).
