DESCRIPTION:The setting up of a general framework for the environmental and
  landscape planning of a protected area\, requires a basic detailed survey
  of this area and its vegetation\, accompanied by a monitoring of the latt
 er\, so that a specific maintenance plan can be implemented accordingly. W
 ith reference to an area of high environmental\, landscape and archaeologi
 cal value\, such as the 'Pulo di Molfetta' (Municipality of Molfetta – S
 outhern Italy)\, some georeferenced floristic surveys have been carried ou
 t\, with relative mapping and monitoring of the vegetation growth. In this
  way\, it has been possible to draw up some detailed management measures f
 or the vegetation\, as well as to plan suitable interventions of ecologica
 l engineering\, aimed at determining the most appropriate conditions for t
 he recovery\, use and sustainable management of this study area\, even for
  tourism purposes. These activities have been conducted through the constr
 uction of a basic model\, which has been implemented in a Geographical Inf
 ormation System (GIS)\, structured on the basis of some Free and Open-Sour
 ce geographic data\, integrated with a geo-localized 3D survey of the geom
 orphology\, architectural structures and the flora-vegetation habitat. The
  survey\, georeferencing and 3D model formation operations have been condu
 cted by means of:\n1) a photogrammetric survey at ultra-low height – var
 iable\, according to the orography - carried out with Unmanned Aerial Vehi
 cles (UAVs)\, to obtain a 3D digital modelling\, having a readable resolut
 ion of at least 2 cm/pixel\;\n2) coverage with a block of frames with nadi
 ral and sub-horizontal orientation\, for a readability optimized to the an
 alysis of both the geomorphology and the existing medium and tall vegetati
 on\;\n3) creation of a framing and support network\, materialized with hig
 h-contrast photographic targets\, measured with RTK methodologies of GNSS 
 satellite positioning and accuracy ≤ 3 cm\, georeferenced in the RDN2008
  Reference Coordinate System - as per Italian regulations\;\n4) restitutio
 n of a 3D digital model\, obtained with SfM (Structure from Motion) techno
 logies\, formed by a resolution of 1-2 cm\, point clouds\, triangular mesh
  and photographic texture\;\n5) formation of a very-high resolution ortho-
 photomosaic\, with GSD (Ground Sampling Distance) ≤ 15 mm\, and of an ad
 equate number of radial sections\, with two views\, each one orthogonal to
  the section plane\;\n6) georeferenced identification of the individual fl
 oristic-vegetational elements and help for the construction of a database 
 containing the agreed attributes defined and aimed at planning the vegetat
 ion layers present.\nThe metric analyses have been conducted with commerci
 al instruments\, such as UAVs systems\, GNSS and photogrammetric processin
 g software\, in order to test a very widespread\, low-cost operational cha
 in in the dimensional and qualitative survey of medium-small extensions\, 
 affected by great biodiversity and an important altimetric variation such 
 as a karst sinkhole.\nIn conclusion\, the results thus obtained have allow
 ed for the inclusion of the geo-localized 3D model in a GIS base for the k
 nowledge of the flora-vegetation habitat\, thanks to which it will be poss
 ible to provide support for the decision-making of planning choices for th
 e territory\, landscape and environment of the study area\, as well as its
  close surroundings\, so as to safeguard its biodiversity and ecosystem re
 lations.
