SSNbler: Assemble 'SSN' Objects
Erin E. Peterson, Michael Dumelle, Alan R. Pearse · 2024
Import, create and assemble data needed to fit spatial-statistical stream-network models using the 'SSN2' package for 'R'. Streams, observations, and prediction locations are represented as simple features and specific tools provided to define topological relationships between features; calculate the hydrologic distances (with flow-direction preserved) and the spatial additive function used to weight converging stream segments; and export the topological, spatial, and attribute information to an ‘SSN' (spatial stream network) object, which can be efficiently stored, accessed and analysed in ’R'. A detailed description of methods used to calculate and format the spatial data can be found in Peterson, E.E. and Ver Hoef, J.M., (2014) .
