5th Annual Spatial-Statistical Stream Network Models training workshop

Event Type: 
Date and Time: 
Mar 29, 2017 8:00 am MDT to Mar 31, 2017 5:00 pm MDT

Two 3-day workshops will be held in Boise, Idaho on March 29-31 & April 3-5.

A new class of spatial statistical network model for data on stream networks has recently been developed & free software is available for implementing the models. SSNs account for network topology (i.e., flow direction, stream size, tributary confluences) and offer significant improvements over many traditional statistical techniques that were developed originally for terrestrial applications.

The SSNs are applicable to common types of stream data (e.g., water quality attributes, biological surveys, habitat conditions) through application of several distributions (e.g., Gaussian, binomial, Poisson). The models also account for spatial autocorrelation among measurements, which makes them powerful tools for mining information from large datasets aggregated from multiple sources. For additional details, please visit the SSN/STARS website or the National Stream Internet website.

These 3-day workshops will consist of a 1-day short-course & 2 days of working with course instructors to apply SSNs to participant’s datasets.

A workshop will include:

  • overviews of two sets of free software (STARS ArcGIS toolset; SSN package for R Statistical Software)
  • software demonstrations for:
  • parameter estimation and modelling continuous, presence/absence (binomial), and count data (Poisson);
  • kriging predictions at unsampled locations and block kriging for discrete areas;
  • uncertainty estimation;
  • simulation and visualization techniques for space-time stream data;
  • monitoring design considerations (developing new designs & supplementing existing ones);
  • discussions of when spatial statistical techniques are most useful and the many new applications that are now possible for stream data;
  • working with instructors to apply the SSNMs to your data

Note that a good working knowledge of statistics and the R statistical program are very useful (but not mandatory) to obtain the greatest benefit from workshop participation. Participants at the 3-day workshop must bring a laptop with access to R statistical software, ArcGIS (versions 10.1 or 10.2), and the ArcGIS Spatial Analyst extension. Please contact the organizers if you cannot meet these requirements.
