Article
Full-text available
In recent decades many Geomatics-based methods have been created to reconstruct and visualize objects, and these include digital photogrammetry, Lidar, remote sensing and hybrid techniques. The methods used to process such data are the result of research straddling the fields of Geomatics and Computer Vision, and employ techniques arising from appr...

Full-text available
An interesting example formalizes balance problems (flow, transportation, traffic and circulation), generally present in civil and environmental engineering disciplines, or in industrial and information ones, as well as in other disciplines of the earth and environmental sciences. Given some observables, it is generally simple to model the linkage...
Article
Full-text available
Throughout history the link between geometry and architecture has been strong and while architects have used mathematics to construct their buildings, geometry has always been the essential tool allowing them to choose spatial shapes which are aesthetically appropriate. Sometimes it is geometry which drives architectural choices, but at other times...
Conference Paper

The Italian City of Matera, awarded European Capital of Culture 2019, leads to a quantitative discussion on the measurement of quality in Geomatics and Applied Geomatics. The starting point is how to choose between optimal models (followed by an innovative goodness of fit test, powerful and easy to be applied), then a transformation of random varia...
Article
Full-text available
The authors, in the 700th year from the birth of Giovanni Boccaccio, intend to celebrate the event by their proper means: statistical, numerical, computing, and cartographic techniques, as used in Geomatics. However, we also mean to have an interface between Geomatics and Humanistics for hybridation of different areas.
Article
The name of Ruggero Giuseppe Boscovich has many spellings: the Croatian Boscovič, linked to his Dalmatian origin, becomes Boscowich in German. Ruggero Giuseppe Boscovich lived and worked in many cities: Rome, Pavia, Venice, Paris, London, Warsaw, Saint Petersburg and Constantinople, where he carried out diplomatic missions. He was a Jesuit and stud...

Full-text available
In photogrammetry a camera is considered calibrated if its interior orientation parameters are known. These encompass the principal distance, the principal point position and some Additional Parameters used to model possible systematic errors. The current state of the art for automated camera calibration relies on the use of coded targets to accura...
Article

This paper deals with the reconstruction of a building, starting from a point cloud. The shape of this building is a non-stellar concave and multi-connected structure, composed of sowns and chains. A sown is the representation of a horizontal plane formed by dense points. A chain is a planar loop modeled by rare points. CCTV structure is defined on...
Article
In the past centuries, scholars, philosophers, dreamers, idealists have devised a better world: they found it easier, other than in books, express it as maps, possibly attractive. Geomatics and Geoinformation can give very important contributions to many human activities; a correct information passes through a different conceived Cartography: see t...
Article

Due to political and social situation which followed local riots and war, in the SW part of Balkan Peninsula, the large existent archaeological and civil treasure, mainly the Orthodox Monasteries, is heavily threatened. So, we need collect, record and make available all information data, which appear representative of this precious heritage. A G.I....
Article
Information Systems may be considered as a part of universal media. The survey and mapping disciplines, particularly Photogrammetry, Remote sensing and GIS, can give very important contribution to many human activities, but they can also be negatively used to support, in very sophisticated ways, the escalation of armies, wars and destruction: in ma...
Conference Paper
The present paper presents an application of non- parametric statistical tests for the analysis of time series of remotely sensed data, acquired by different sensors of the same series. A set of points, extracted from the NOAA AVHRR GAC pathfinder dataset, which covers the period 1981-2001, was used as test dataset. Two tests, the Kruskal-Wallis an...
Chapter
The satellite geodesy and the space photogrammetry are entering into the theater of the surveying and photogrammetry measurements. Their high importance and quick diffusion are constraning to assume a new point a view also for the simulation, the adjustment and the evaluation. Some statistic, numerical and informatic problems must be changed, e.g....
Conference Paper
Full-text available
The realisation and the validation of thematic cartography made with Remote Sensing techniques could not put aside from a preventive phase of analysis of the ground coverage data set. Very often training set and testing set are based exclusively on the visual recognition of the coverage classes. For these reasons, sometimes the operator can attribu...
Article
Three classes of data (network structures; dense, but irregular, fields of points; raster data and grid parameters) could be classified in the survey and mapping disciplines (e.g., photogrammetry, remote sensing and GIS). Regarding the solution strategies, some different numerical techniques: direct algorithms and sequential strategies; iterative m...
Article
Data processing, in the field of information technology, requires new tools, involving discrete mathematics, like data compression, signal enhancement, data classification and understanding, hypertexts and multimedia (considering educational aspects too), because the mass of data implies automatic data management and doesn't permit any a priori kno...
Conference Paper
A summary on numerical cartography and digital photogrammetry, taking into account also some aspect of GIS’s and image processing, is presented, in order to list the principal problems of spatially referenced data analysis. As it is very well known, reliability and robustness are important properties, that may be assured in the data analysis by usi...
Conference Paper
A summary of cluster analysis techniques and graph theory algorithms is presented and their application to data archiving is discussed. A specific system of programs and a preliminary example show that the procedures prove to be effective.
Chapter
Images supply large amounts of data, that need appropriate statistical and numerical techniques, in order to achieve their restoration and validation. In this work some procedures of data processing are presented; they combine suitably optimality from the statistical point of view and practicability from the numerical one. Furthermore they have bee...

The book contains 31 papers on different fields of application and the problems of modelling and organizing data in structures, the processing techniques of GIS data for queries to the system and the so-called Dynamic GIS have been reported in detail. A final paper on Computer Graphics principles is included. Its contents can be ideally collected i...
Conference Paper
The Digital Elevation Model (DEM) is a fundamental element of Geographic Information Systems (GIS), since it provides the spatial reference for the different layers included in the system (e.g., Environmental Impact Assessment) and related to the topography. In this paper an interpolation strategy based on an integrated deterministic and stochastic...
Article
The geometric observables in geodesy, which can be determined by eg surveying and photogrammetry, are all simple, or more complex functions of relative position of two points. They are influenced by various physical fields, like the earth's gravitational field and the field of atmospheric refraction. The relation between the geodetic observables an...
Article
Full-text available
The paper has two main targets: to prove by numerical experiment on simulated data (exact solution a priori known) that the integrated approach gives superior results that can’t be achieved neither by pure (“incorrect”) λ.s. adjustment nor by a λ.s. adjustment of observations corrected by some a priori long wave length gravity model; to find among...
Article
In December 1982 a large scale landslide occured in the district of Ancona (Italy), including also some residential areas of the city. A leveling network was established to control the settlement of the terrain (fig. 1) and eleven high precision spirit levelings were performed during the following two years (tab. 1).

A number of simulations of the compensation of the 1st order national geodetic network have been undertaken. These fall within the scope of the 1985 National Doppler Plan (PDN85) activities carried out by the Istituto Geografico Militare (IGMI). The simulations were performed by supplementing classical geodetic measurements with vertex coordinate d...
Article
A working group has been set up in order to analyze the causes, to control the ground settling and to determine the consequent destination of the area. Inside this working group, the geodesists have performed the control surveying by topographic and photogrammetric instruments. The former is a still going operation intended to control the settlemen...

A gravimetric geoid has been determined in the Italian area: this paper reports procedures and results. The data which have been used are the gravity anomalies supplied by BGI. A collocation procedure has been applied locally using the Rapp ('79) 180 X 180 model as reference field. The geoidal height m.s.e. is almost everywhere less than 0.5 m on t...
Article
The geoid undulations can be estimated on a global or a local scale, by using many different geometrical or physical observations. In Italy the first estimates by some collocation technique, have been performed from astrogeodetic, gravimetric, altimetric data, with an accuracy ranging between 50 cm and 80 cm. The results so far obtained and future...

Article
The use of Mekometer in checking the structures is limited by its narrow possibilities of movement on vertical plane. To obviate this limitation and therefore make possible the extension of the check to points located outside the operation range of the instrument, an appropriate equipment was manufactured. This consists of a mirror rigidly connecte...
Article
The research done by the Sections of Survey and Mapping, and Environmental Engineering of a DIIAR of the TU of Milan (Italy) about the assessment of aerial volumes in the Lombardia Region of Italy can be here presented as a case study suitable to be applied otherwise. It required the acquisition of: DTM, orthoimage, environmental database both spat...
Article
The basic idea underlying the proposed approach to spatial-temporal modeling is to combine, at the different levels, the potential of various techniques and to exploit their performance. A three level procedure is used. Firstly low level polynomial interpolation removes a general trend; then finite element method follows to match local variations....
Article
Modelling reality is representing phenomena: descriptions of events are not always reducible to rigorous mathematical functions, requesting therefore statistical methods to reproduce their effects. Throughout both classical and innovative procedures of statistical analysis, the implementation of software can classify data, improving results with ev...
