Qi, and Michael L. Highlights All Posts About: Bradley Miller Miller No comment yet New estimated errors are calculated for each raster cell based on the combination of the two input rasters. Download the latest version of Adobe Reader, free of charge.

Similar to other geoprocessing tools available in ArcGIS Desktop, REPTool can be run from a dialog window, from the ArcMap command line, or from a Python script. Error covariances can also be included in the calculation of error propagation, but are not required.

Geological Survey Raster Error Propagation Tool (REPTool) is a custom tool for use with the Environmental System Research Institute (ESRI) ArcGIS Desktop application to estimate error propagation and prediction uncertainty in Suggested citation: Gurdak, J.J., Qi, S.L., and Geisler, M.L., 2009, Estimating prediction uncertainty from geographical information system raster processing—A user’s manual for the Raster Error Propagation Tool (REPTool): U.S. raster calculator).

Geological Survey Center of Excellence for Geospatial Information Science (CEGIS) Estimating Prediction Uncertainty from Geographical Information System Raster Processing: A User’s Manual for the Raster Error Propagation Tool (REPTool) By Jason The error for the input rasters may be specified as either spatially invariant or spatially variable across the spatial domain. Gurdak, Sharon L. Geological Survey Techniques and Methods 11–C3, 71 p.

REPTool is designed to introduce concepts of error and uncertainty in geospatial data and modeling and provide users of ArcGIS Desktop a geoprocessing tool and methodology to consider how error affects Geisler Abstract The U.S. The same applies for spatial layer mashups where the grids provide the input variables for equations that are calculated spatially (i.e. REPTool consists of public-domain, Python-based packages that implement Latin Hypercube Sampling within a probabilistic framework to track error propagation in geospatial models and quantitatively estimate the uncertainty of the model output.

This toolbox for ArcGIS uses standard error propagation equations to simultaneously calculate the result of basic math expressions along with the estimated error of that result.
