TL;DR: The World Stress Map Project (WSMP) database as mentioned in this paper provides a global database of contemporary tectonic stress information of the Earth's crust, and the 2005 release of the WSMP database provides, for some areas, high data density that enables us to investigate third-order (local) stress field variations and forces controlling them such as active faults, local inclusions, detachment horizons, and density contrasts.
Abstract: [1] The World Stress Map Project compiles a global database of contemporary tectonic stress information of the Earth's crust. Early releases of the World Stress Map Project demonstrated the existence of first-order (plate-scale) stress fields controlled by plate boundary forces and second-order (regional) stress fields controlled by major intraplate stress sources such as mountain belts and zones of widespread glacial rebound. The 2005 release of the World Stress Map Project database provides, for some areas, high data density that enables us to investigate third-order (local) stress field variations, and the forces controlling them such as active faults, local inclusions, detachment horizons, and density contrasts. These forces act as major controls on the stress field orientations when the magnitudes of the horizontal stresses are close to isotropic. We present and discuss examples for Venezuela, Australia, Romania, Brunei, western Europe, and southern Italy where a substantial increase of data records demonstrates some of the additional factors controlling regional and local stress patterns.

TL;DR: The World Stress Map (WSM) as discussed by the authors provides insight into large-scale patterns of stress orientations (i.e., first-order stress patterns due to plate boundary forces and secondorder stress pattern due to topography), large lateral density variations, and deglaciation effects.
Abstract: The World Stress Map (WSM), published in April 2007 by the Commission for the Geological Map of the World and the Heidelberg Academy of Sciences and Humanities, displays the tectonic regime and the orientation of the contemporary maximum horizontal compressional stress at more than 12,000 locations within the Earth's crust. The Mercator projection is a scale of 1:46,000,000.
The WSM provides insight into large-scale patterns of stress orientations (i.e., first-order stress patterns due to plate boundary forces and second-order stress patterns due to topography), large lateral density variations, and deglaciation effects. Furthermore, the WSM contains a number of regions with high data resolution that enable users to investigate variations in stress orientations on local scales and to discuss factors controlling third-order stress patterns such as active faults, local inclusions, detachment horizons, and density contrasts. Forces resulting from these geological subsurface structures control the stress field orientations especially when magnitudes of the horizontal stresses are close to each other.
