Functions
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getNHDReachcodeAndMeasureForGageSourceFea
	Get NHD Reachcode and measure along reach for a streamflow gage identified by a source_fea (e.g.
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getLocationForStreamGageByGageSourceFea
	Get lat/lon, in WGS84 (EPSG:4326), from gage point layer (Gage_Loc) for gage identified by a source_fea (e.g.
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getLocationForStreamGageByReachcodeAndMeasure
	Get lat/lon, in WGS84 (EPSG:4326), from gage point layer (Gage_Loc) for gage identified by reachcode and measure.
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getLocationForStreamGage
	Get lat/lon, in WGS84 (EPSG:4326), from gage point layer (Gage_Loc) for gage identified by reachcode and measure.
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getComIdForStreamGage
	Uses NHDFlowline and/or NHDReachCode_ComID table(s) to lookup the ComID associated with a stream gage identified by reach code and measure.
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getPlusFlowPredecessors
	Get the immediate predecessors of the NHDPlus2 PlusFlow feature of comID.
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getUpstreamReachesSQL
	Recursively searches PlusFlow table in an SQLite database for all stream reaches upstream of a given reach.
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getBoundingBoxForCatchmentsForGage
	Get bounding box coordinates (in WGS 84) for the drainage area associated with a given NHD (National Hydrography Dataset) streamflow gage identified by a reach code and measure.
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getCatchmentShapefileForGage
	Get shapefile (in WGS 84) for the drainage area associated with a given NHD (National Hydrography Dataset) streamflow gage identified by a reach code and measure.
def	ecohydroworkflowlib.nhdplus2.networkanalysis.getCatchmentShapefileForGageOGR
	Get shapefile (in WGS 84) for the drainage area associated with a given NHD (National Hydrography Dataset) streamflow gage identified by a reach code and measure.
