  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. Unable to locate precise location of Cachoeira Morena; georeferenced to the geographic center of Rio Uatumã (along the shore). Using Google Maps, located Rio Uatumã, which passes through Presidente Figueiredo and Itaprianga, AM. Used the measurement tool to measure a straight line between the end of the river, at the Balbina Dam, and the headwaters of the river. Halved that distance to approximate the midpoint of the river. Used Canadensys Lat/Long Crosshairs to find the coordinates. Input coordinates, linear extent (the distance from the chosen midpoint to the point on the farthest point on the feature that is within the administrative boundaries specified in the locality description - 101070 m.), and measurement error (1 m.) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to the Georeferencing Quick Reference Guide, Named Place: River, stream, road, path).
