GEOMATIC APPLICATIONS TO URBAN PARK IN PALERMO

ABSTRACT: Over the last few years topographical techniques have developed an exponential trend towards simplifying and speeding, both survey operations and analysis of data collected reaching at the same time ever higher levels of accuracy. Among the technologies that are increasingly taking the field in this context is part of the Mobile Mapping System (MMS) that, on any mobile platform, combines sensors and measurement systems designed to provide a 3D position of the platform and, at the same time, capable to acquire geographic data without the aid of control points on the ground. The study reported concerns the verification of the reliability metrics and a qualitative MMS in order to evaluate its behavior in a particularly insidious as it can be an urban park; in particular, we report a series of experiments carried out from 2012 to the present in which we tried to test the potential of the system, comparing it with data from systems more “traditional”, and to exploit all the products in an integrated survey carried out in dynamic mode.
