EXTRACTING TIDAL STREAM NETWORKS FROM HIGH-RESOLUTION REMOTE SENSOR IMAGERY:A PRELIMINARY STUDY
Coastal Marshes Tidal Stream Networks High-Resolution Imagery Classification Distance Modeling NonDirectional Filtering Interactive Editing
2015/12/29
In this paper we report the results of a pilot project we conduct to develop a semi-automated approach for tidal stream network extraction from remote sensor data. Our test site is part of the North I...
Modelling Uncertainty of Stream Networks Derived from Elevation Data Using Two Free Softwares: R and SAGA
DEM Stream Network Uncertainty Modeling R SAGA
2013/3/5
Stream networks are considered important units in many environmental decision making processes. The extraction of streams using digital elevation models (DEMs) presents many advantages. However it is ...
Top-kriging - geostatistics on stream networks
Top-kriging - geostatistics stream networks streamflow-related variables
2009/5/13
We present Top-kriging, or topological kriging, as a method for estimating streamflow-related variables in ungauged catchments. It takes both the area and the nested nature of catchments into account....
Sparse sampling：Spatial design for monitoring stream networks
Sparse sampling Spatial design monitoring stream networks
2009/2/11
Spatial designs for monitoring stream networks, especially ephemeral systems, are typically non-standard, `sparse' and can be very complex, reflecting the complexity of the ecosystem being monitored, ...
