OATools: An ArcMap add-in for the orientation analysis of geological structures

“Highlights:

  • Tools for orientation analysis of structural data were developed for ArcGIS 10.2.
  • OATools analyze directional data in relation to their spatial information.
  • Both angular and spatial characteristics of the data can be explored in ArcGIS.
  • The structural conditions of the crystalline complex are described using the OATools.

“This paper describes Orientation Analysis Tools (OATools), a new add-in, which has been developed for ArcGIS software (ESRI) to allow the spatial analysis of structural data. These tools bring a complex approach to structural data analysis that highlights the spatial aspect of oriented data. In this paper we introduce the functionality of this add-in, which allows users to plot selected data in azimuthal projection, calculate and plot fold axes, construct density distribution diagrams and rose histograms, and create maps of spatial averages and fold axes.
