Spatial data created / processed by commercial or open source software follows standards by institutions like the Open Geospatial Consortium; this standards allow the interoperability of the vector or raster data among different software however standards apply to the position but not the style. Styles from ArcGIS were not easy to convert to formats compatible with QGIS, specially if you don’t have the commercial software.
Governmental offices release spatial data as land use, land cover, infraestructures, and sometimes release styles in ArcGIS formats posing a great obstacle for the QGIS users. This tutorial shows the complete procedure to convert ArcGIS Style to QGIS as *.xml format with a case study of land cover from Costa Rica. The tutorial is developed in Windows, if you are a Linux and Mac users its necessary to install Mdbtools on your own operating system.
