Il progetto di rilievo Antonio Zanca (1861/1958) ed il nuovo progetto di rilievo
2019
Historical path and state of the art reliefs on the cathedral of Palermo. Particular attention to the important work carried out by the architect Zanca and then to analyze the work I did on the survey project using a topographic station.

Dinamiche insediative nel comprensorio di Cignana. Continuità e discontinuità tra l'età imperiale e l'età bizantina
2013
The aim of this paper is to illustrate the development of rural settlement of Roman age, in the hinterland of Cignana (close to Agrigento, Sicily). In this area were identified an Early Roman age villa and a Late Roman/Byzantine village, partially excavated by the Superintendence of Agrigento. Since 2007 the Dep. of Beni Culturali of University of Palermo has carried out an intensive and systematic archaeological survey around Cignana, where about 200 archaeological sites were identified. Many sites (farms, and perhaps also some villa) were inhabited from late Hellenistic to Late Roman/Byzantine ages, and some have become very large villages; also, many settlements are placed along the prin…

Close range photogrammetry for measurement of paintings surface deformation
2009
The paper describes the first results about a study on the measurement of paintings surface deformation. The study was carried out using one ancient painting model made in a restoration laboratory and consolidated with the materials and dilutions most frequently used in the field of conservation. The restorers suppose deformations of the paintings surface from 0.1 mm to some millimetre when the painting model is keeping in environment with the presence of humidity and temperature fluctuations. The main purpose of the study is to evaluate the relative accuracy and the reliability of multi-images photogrammetric techniques related to the camera stations network and to the commercial software …
3D mosaic documentation using close range photogrammetry
2015
The paper describes the close range photogrammetric survey of a roman mosaic stored at Regional Archaeological Museum “Antonino Salinas” in Palermo (Italy). The aim of the work is the production of a full-scale representation (scale 1:1) of the mosaic useful for documentation and restoration processes. The research has allowed evaluating limit and potentiality of image-based approach using photogrammetric and computer vision (Structure for Motion) techniques in a context where the metric point of view is a very important factor.
Robustified smoothing for enhancement of thermal image sequences affected by clouds
2015
Obtaining radiometric surface temperature information with both high acquisition rate and high spatial resolution is still not possible through a single sensor. However, in several earth observation applications, the fusion of data acquired by different sensors is a viable solution for so called image sharpening. A related issue is the presence of clouds, which may impair the performance of the data fusion algorithms. In this paper we propose a robustified setup for the sharpening of thermal images in a non real-time scenario, capable to deal with missing thermal data due to cloudy pixels, and robust with respect to cloud mask misclassifications. The effectiveness of the presented technique…
Soil water content monitoring: a verification of thermal inertia approaches on low spatial, high temporal resolutions images
2013
Soil water content is directly connected with soil evaporation and plant transpiration processes; in particular, soil water content within the root zone, is readily available to evapotranspiration. Thus, in agricultural sciences, the assessment of the spatial distribution of soil water content could be of utmost importance in evaluating crop water requirement. In spite of limitations to applicability due to contingent cloud cover, water content of the upper part of the soil can be determined by applying the thermal inertia approach by coupling optical and thermal infrared images. The thermal inertia formulation, rigorously retrieved on bare soil, has been also verified on soils partially co…
Critical analysis of the thermal inertia approach to map soil water content under sparse vegetation and changeable sky conditions
2012
The paper reports a critical analysis of the thermal inertia approach to map surface soil water content on bare and sparsely vegetated soils by means of remotely sensed data. The study area is an experimental area located in Barrax (Spain). Field data were acquired within the Barrax 2011 research project. AHS airborne images including VIS/NIR and TIR bands were acquired both day and night time by the INTA (Instituto Nacional de Tecnica Aeroespacial) between the 11 th and 13 rd of June 2011. Images cover a corn pivot surrounded by bare soil, where a set of in situ data have been collected previously and simultaneously to overpasses. To validate remotely sensed estimations, a preliminary prox…
Preliminary results of the 2017 season in the Amazonian earthen structures known as geoglyphs.
2018
O trabalho realizado pela equipe de pesquisa multidisciplinar, liderada pela Universitat de Valencia Estudi General (UVEG) e a Universidade Federal do Acre (UFAC), de detalhamento da topografia, em especial na RESEX Chico Mendes, criou progresso significativo no conhecimento das estruturas de terra construídas na paisagem amazônica, conhecidas popularmente como geoglifos, no que se refere a aplicação de topografia de alta precisão para algumas das estruturas, compreensão geral fenômeno e aplicação de uma nova estratégia de pesquisa, com o auxílio de ferramentas como o Google Earth, Google Maps, GPX, OpenStreetMap e Lidar. Ainda há muito trabalho de campo a ser feito na Amazônia Ocidental, n…
