Two investigations that exemplify in a simple way new ways of linking geo-referenced data with public domain applications to obtain, process, survey and model urban intervention projects in medium-sized cities (e.g. Tandil and Rauch in Argentina). One of the researches relies on georeferencing technology to optimize the installation of public transport shelters. The other one proposes the use of a georeferencing location application for the development of audio guides oriented to promote the built heritage.
