Building extraction in aerial orthophotos is crucial for various applications. Currently, deep learning has been shown to be successful in addressing building extraction with high accuracy and high ro...
The Emilia Romagna Region (N-E Italy) and in particular the Adriatic Sea coastline of Ravenna, is affected by a noticeable subsidence that started in the 1950s, when the exploitation of on and off-sho...
In mobile laser scanning systems, the platform’s position is measured by GNSS and IMU, which is often not reliable in urban areas. Consequently, derived Mobile Laser Scanning Point Cloud (MLSPC) lacks...
In this paper we present a quality evaluation of two-dimensional building acquisition. We propose methods for identification and quantifi-cation of differences between independently acquired regions, ...
The formalization description of user needs is one of key issues in GIS on-demand services. A number of user demand documents is collected, the paper analyzes them in semantics and geometric aspects, ...
In this paper, a systematic scheme of building semantic description of Geographic Processing Services (GPServices) based on ontology is proposed. According to the principle of ontology, GPServices tax...
In this paper we present a new efficient edge detection algorithm for the extraction of linear features in both range and intensity image data. In the proposed algorithm the distinguished points, whi...
Finding and accessing suitable geographic information to satisfy various applications in the open and distributed environments of Spatial Data Infrastructures (SDIs) is a crucial task. However, becaus...
Describing a landscape means making link between concepts of visible features and people’s perception. Most landscape description methods underline salient entities which are a key trigger for wayfind...
The automatic reconstruction of roofs and buildings has been an important research topic during the last years. This paper elaborates on the automatic and semi-automatic reconstruction of roofs from a...
Direction relation is an important spatial relation. Descriptions and representations for direction relations have different levels of detail because of different dimensions of spatial objects and dif...
Data quality statements are now entrenched in metadata standards worldwide. I contrast the needs of the user with the production-control mechanisms of the producer, and argue that metadata standards a...
The CYCLOPES project aims at providing high level biophysical products such as LAI, fAPAR, fCover over the globe at 1 km spatial resolution at a 10 days time interval. To provide continuity over long...
