About¶
This plugin provides an alternative version of the core InVEST RouteDEM utility. This version replaces the standard “Threshold Flow Accumulation” input value with a “Threshold Flow Accumulation Range” input, which allows the model to compute outputs for a range of TFAs in a single run.
Threshold Flow Accumulation (TFA) is a stream delineation algorithm parameter that specifies the number of upstream pixels that must flow into a pixel before it is classified as a stream. Since Threshold Flow Accumulation is only relevant in cases where streams are calculated from the flow accumulation output, this plugin always calculates flow direction, flow accumulation, and streams.
Threshold Flow Accumulation Range¶
In this plugin, the “Threshold Flow Accumulation Range” input takes the form start_value:stop_value:step_value, where:
start_value: An integer specifying at which value to start.stop_value: An integer specifying at which value to stop (not inclusive).step_value: An integer specifying the incrementation from thestart_valueup to thestop_value.
The model inputs are otherwise identical to those of the InVEST RouteDEM utility.
