Service Description: This data represents isolated flowlines in the Roaring Fork watershed to be used in a web map showing connected wetland and deepwater habitat features from the National Wetlands Inventory (NWI) dataset and various hydrographic features from the National Hydrography Dataset (NHD). A connectivity model was used to determine isolation/connectivity using a 0, 5, & 10 meter buffer of features. The general model process steps include:
NWI was used as input data (other data can be added as input e.g. NHD) to determine "seed" jurisdictional waters. Currently, “seed” jurisdictional waters was defined as all Estuarine, Lacustrine, Tidal Riverine, Lower Perennial Riverine, and Upper Perennial Riverine NWI features.
Select all NWI features in the study area that are "potential connectors". Currently, “potential connectors” were defined by excluding NWI features that had drier water regimes (temporarily flooded [A], continuously saturated [B], Continuously Saturated [D] and Seasonally Flooded/Saturated [E] and all Palustrine Farmed [Pf] features).
Select all the "potential connectors" that intersect the "seed" data with the customized buffer distance.
Continue iterations of step 3 by using the output (“seed” + intersecting “potential connectors”) as the “seed”. Iterations repeat until the count of selected NWI features does not increase.
Select all NWI features (including non-connector wetlands) that intersect the final output of step 4. All selected features are exported as "Connected NWI Features...".
Invert the selection and export remaining features as "Isolated NWI Features..."
