Accompagnata da una delle sue inseparabili caratteristiche, quella di operare sempre un po' sottotraccia anche ove individuata quale supporto necessario e fondamentale a servizi di pubblica e primaria utilità, la cartografia sta oggi conoscendo uno step evolutivo importante, dal momento in cui i grandi player della navigazione per auto e - un po' più defilate - le solite Big Tech, hanno manifestato (come al solito soltanto i primi in modalità esplicita) quei progetti che discendono dall'ambizione che è causa delle loro nuove sfide di mercato.
GEOMATICS AND ROBOTICS: A WINNING COMBINATION TOWARDS THE AUTOMATION OF THE SURVEY
The discipline of Geomatics itself is experiencing a phase of profound innovation, resulting from an ever greater integration with technologies and methods developed, among others, in the field of Robotics and of IT.

In this article, we aim to reflect on the contributions that social cartography or participatory mapping could make towards identifying the spatiality –or the specifically spatial aspects– of social processes. To this end, we analyze a mapping process we coorganized in Cabure-í, Misiones, alongside a cooperative of small-scale farmers. This mapping aimed to highlight, for cooperative members, the spatial dimension of the current situation of land tenure in the area, which would enable to reframe precarious tenure situations as an issue on a collective scale, instead of as a problem pertaining to individual families. Furthermore, for our research team, this mapping caused us to question our own assumptions around the spatial order configured by the cooperative’s members. While we assumed that the official cadastral land divisions would only be relevant to the population insofar as they legitimize eviction orders against these small farmers –almost none of which hold land titles–, we found that these farmers have also reappropriated the cadastral map to draw their own plot demarcations.
In recent years, there have been qualitative changes in surveying associated with the use of robotic systems, such as unmanned aerial vehicles. Currently, traditional geodetic and topographic technologies are giving way to high-precision and high-performance systems using robotics. The technology of aerial photography from drones for mapping territories, operational monitoring linear structures, construction sites, as well as for engineering and underground surveys, solving cadastral matters, building realistic three-dimensional terrain models, etc., is gaining more and more popularity in the world. The transition to new technologies entails restructuring not only the methods of determining coordinates, but also the stages of pre-design and design work. The authors describes the capabilities of geographic information systems for automating some stages of field geodetic data cameral processing obtained through using unmanned aircraft. As a result of the study, it was discovered that the marks of the earth’s surface, read from the constructed digital map, are in good agreement with those obtained as a result of the ground-based geodetic survey.
Unmanned aerial vehicles (UAVs) have advantages such as a relatively low operating cost and excellent ground–sample distance (GSD) compared with conventional manned aerial photogrammetry. Recently, the development of sensor technology has enabled digital mapping, terrain model generation, economic evaluation, monitoring, cadastral surveying, coastal surveying, and ground surveying. However, existing studies have shown the limited validity of UAVs for spatial information construction owing to limited experiments and analyses. In this study, the validity of UAVs for spatial information construction was evaluated, and recent case studies related to the accuracy of the results were analyzed. The results of 34 studies including quantitative results of UAV accuracy within the last 5 years were investigated, and the correlations of flight altitude, accuracy, and ground control point (GCP) number are presented through the analyses of existing studies. The horizontal and vertical accuracies of terrain information using a UAV were 0.51 m and 0.56 cm, respectively. The horizontal and vertical accuracies were correlated with the flight altitude and GCP number, with the flight altitude having a greater effect than the GCP number. In the future, the results of this study will be used as a basis to examine the validity of geospatial information construction using a UAV.
The main requirements for the land monitoring system are identified, including requirements for its functionality, information support, visualization of spatial information, interactive maps, database structure, general architecture, analytical criteria and other types of support.
The main directions of land monitoring, within which the automated system should function, in particular, monitoring of civil law transactions in terms of territories, forms of ownership, land categories; monitoring of price dynamics; monitoring the condition of lands by their quantitative and qualitative characteristics; assessment and forecasting of land transformation.
The requirements for the subsystems of administration, ergonomics, infrastructure, ensuring the turnover of changes, geodetic and mathematical basis, etc. are also substantiated.
The need to ensure the protection of information, including confidential information, is emphasized, as the land monitoring system should contain not only information on the objects of monitoring, but also information on the subjects of land relations, whose rights should be guaranteed.
The need to use directories and classifiers, in particular the classification of administrative-territorial entities of Ukraine, types of economic activity, as well as integration with various official state registers as part of the national geospatial data infrastructure platform is taken into account.

As part of the management of reimbursement of damages from wildlife, the Direzione Capitale Naturale, Parchi ed Aree Protette of Regione Lazio made use of the OS G3WSUITE framework (based on QGIS-Server) for the
creation of a web cartographic management system.
The application allowed to migrate a dedicated QGIS project defining, in addition to the rendering aspects, also the form structure and the editing widgets dedicated to the individual attributes.
The administration component has made it possible to define editing permissions based on geographical constraints linked to authorized users.
The collected data will be a support for a correct and rational planning of future interventions making the management of available economic and human resources more effective and targeted.
As a basic surveying and mapping work, small uav has been widely used in large scale topographic mapping. According to the needs of production and construction, digital mapping methods and aerial photogrammetry are used to provide technical support for large scale topographic mapping in engineering construction surveying and mapping, urban planning and construction, cadastral surveying and other directions. In order to control the small uav in the terrain elevation information, mapping proportion accuracy and other aspects to get better improvement, the practice of small uav in large scale topographic map is deeply analyzed, in order to understand the practical application value of small uav in large scale topographic map.
The Global Map continues the long Florentine cartographic tradition, which is characterized by the ability, the tendency to perfection and the artistic vision but, above all, the passion. Like the one of its general manager Andrea Bonomo, for which the maps are the main instrument of knowledge.
Abstract. Europe’s big cities and metropolitan areas constitute an ecosystem where climate trends are having, and will continue to have, a big impact on the population in the short, medium, and long term. Therefore, the task of generating a mapping approach over urban ecosystems to provide indicators assessing their sustainability and facilitating the design and implementation of policies and derived actions has become a priority for the Institut Cartogràfic i Geològic de Catalunya (ICGC) as a mapping agency.The ICGC has been using its own assets and competences in airborne Earth Observation for data capture and processing as well as inclusion of additional data such as cadastral databases and digital surface models to generate a set of urban sustainability indicators. ICGC has designed flight campaigns at a very high spatial and spectral resolution in visible, near infrared and long wave infrared regions, processed geospatial data and finally transformed geoinformation into demanded ICGC products over urban ecosystems such as urban green, solar potential, light pollution, energy leaks or urban heat island effect. This approach has been applied in coordination with urban planning stakeholders in different cities and is planned to be extended to the majority of urban ecosystems in Catalonia.This paper presents a critical summary of the main advantages, disadvantages, constrains and lessons learned in the search for feasible, available and desirable responses from the earth-observation airborne-sensor point of view to the main urban ecosystem challenges.
Despite significant developments, 3D technologies are still not fully exploited in practice due to the lack of awareness as well as the lack of understanding of who the users of 3D will be and what the user requirements are. From a National Mapping & Cadastral Agency and data acquisition perspective, each new 3D feature type and element within a feature added (such as doors, windows, chimneys, street lights) requires additional processing and cost to create. There is therefore a need to understand the importance of different 3D features and components for different applications. This will allow the direction of capture effort towards items that will be relevant to a wide range of users, as well as to understand the current status of, and interest in, 3D at a national level. This paper reports the results of an initial requirements gathering exercise for 3D geographic information in the United Kingdom (UK). It describes a user-centred design approach where usability and user needs are given extensive attention at each stage of the design process. Web-based questionnaires and semi-structured face-to-face interviews were used as complementary data collection methods to understand the user needs. The results from this initial study showed that while some applications lead the field with a high adoption of 3D, others are laggards, predominantly from organisational inertia. While individuals may be positive about the use of 3D, many struggle to justify the value and business case for 3D GI. Further work is required to identify the specific geometric and semantic requirements for different applications and to repeat the study with a larger sample.
Abstract. The crisis management of a disaster, whether caused naturally or by human action, requires a thorough knowledge of the territory involved, with regard to both its terrain and its developed areas. Therefore, it is essential that the National Mapping and Cadastral Agencies (NMCAs) and all other public and scientific institutions responsible for the production of geospatial information closely co-operate in making their data in that field available. This crucial sharing of geographic information is a top-level priority, not only in a disaster emergency situation, but also for effective urban and environmental planning and Cultural Heritage protection and preservation. Geospatial data-sharing, responding to the needs of all institutions involved in disaster surveying operations, is fundamental, as a priority, to the task of avoiding loss of human lives. However, no less important is the acquisition, dissemination and use of this data, in addition to direct, “in-the-field” operations of specialists in geomatics, in order to preserve the Cultural Heritage located in the crisis area. It is in this context that an NMCA such as the Italian Military Geographic Institute (IGMI) plays a key role.
