This article summarizes the experience gained between 2012 and 2013 by the department of "Civil Engineering, Environmental,Aerospace and Materials" of University of Palermo on the integrated survey of Ninni Park Cassara Park in Palermo and thesubsequent testing of methods, tools and techniques based on current research regarding the acquisition and processing of GNSS(Global Navigation Satellite System) data and laser-scanner. A fruitful time dedicated to the design of the survey has allowed us tobecome aware of the critical issues that the site presents because of its vast extent and diversity in size and number of the elementsof which it is composed. The work has been addressed thematizing the elements to detect and selecting the techniques as possibleeconomic and fast to be applied in the acquisition phase. Sixteen control points evenly distributed within the site were firstmaterialized and detected with static GNSS mode.The survey mode NRTK (Network Real Time Kinematic) of the elements was then planned and carried out. The survey of thenumerous planting was done by exploiting the mode with EGNOS (European Geostationary Navigation Overlay Service) correction.We continued the work experimenting with MMS (Mobile Mapping System) acquisition through which it was possible to acquiredata on the morphology of the terrain, the conditions of the state of footpaths, buildings and on the distribution of street furniture.The point clouds obtained were subjected to both automatic and manual procedures to verify, finally, their actual descriptivepossibilities of real forms detected.
