Replicability and Reproducibility in Geospatial Research: A SPARC Workshop

ASU's Spatial Analysis Research Center (SPARC) is very excited to host its first Replicability and Reproducibility Workshop, taking place at Arizona State University on February 11 and 12, 2019. Please see below for workshop information, including program of events, accommodation information and list of workshop participants.

About the workshop:

Replicability and reproducibility (R&R) have always been core requirements of scientific research. Recently, cases of failure to replicate previously published findings have received widespread public attention. As research grows more complex and increasingly reliant on data and software, concerns about replicability will grow rather than diminish. For example, different software packages may produce different results even when the same technique of spatial analysis is applied to the same data or analysis results cannot be reproduced by the same software due to the lack of proper metadata or provenance documenting the spatial processing and parameters used. Geospatial researchers may need to be especially concerned about replicability, such as when results from one geographic area fail to be replicated in other geographic areas.

This small and focused workshop will address the following questions and related issues:

What forms of failure to replicate exist in the geospatial sciences? Can a formal framework be devised?
In what areas of geospatial research is the danger of non-replicability most severe?
What mechanisms can be used to avoid or minimize the danger of such failures?
Do we expect the results of model calibrations to be constant over space and if not, what are the implications for spatial analysis?
How should R&R be incorporated into the design and implementation of future spatial software?
How should students be made aware of these issues?
What follow-on activities might draw greater attention to these issues?

Organizing committee

The R&R Workshop is possible thanks to the hard work of the organizing committee, including: Mike Goodchild, Arizona State University and UC Santa Barbara; Stewart Fotheringham, Arizona State University; Wenwen Li, Arizona State University; and Peter Kedron, Arizona State University. Logistical planning for the workshop was made possible thanks to the work of Nick Ray, assistant director of operations to the School of Geographical Sciences and Urban Planning and executive assistant to the Spatial Analysis Research Center.


Participants of the R&R Workshop will be staying at Tempe Mission Palms, conveniently located near Mill Avenue – the heart of Tempe and a short walk from Arizona State University's Tempe campus.
