The new national IdroGEO web platform allows the navigation, social sharing and download of data, maps, reports of the Italian Landslide Inventory, national hazard maps, and risk indicators. It is a tool for communication and dissemination of information to support decisions in risk mitigation policies, land use planning, preliminary design of infrastructures, prioritization of mitigation measures, management of civil protection emergencies, and environmental impact assessment. The challenges that have been faced during the design and development of the platform concern usability, access on multiple devices (smartphones, tablets, desktops), interoperability, transparency, reuse of information and software in the public sector, and improvement of the updating of the Italian Landslide Inventory. The methodologies and solutions adopted to address them include Progressive Web Application (PWA), Application Programming Interface (API), open standards, open libraries, and software. A landslide inventory management system has been developed via REST API for data entry and approval workflow in order to maintain the inventory in a distributed and collaborative manner. As a result, IdroGEO provides a public service for citizens, public administration, and professionals, using the “mobile first” approach and with scalable and reliable architecture. IdroGEO represents a solid infrastructure for the interoperability of data that serves as the foundation for creating a first knowledge-graph on landslides and the community who manages them.

Technology has become an essential part of the translation profession. Nowadays, computer-assisted translation (CAT) tools are extensively used by translators to enhance their productivity while maintaining high-quality translation services. CAT tools have gained popularity given that they provide a useful environment to facilitate and manage translation projects. Yet, little research has been conducted to investigate the usability of these tools, especially among Arab translators. In this study, we evaluate the usability of CAT tool from the translators’ perspective. The software usability measurement inventory (SUMI) survey is used to evaluate the system based on its efficiency, affect, usefulness, control, and learnability attributes. In total, 42 participants completed the online survey. Results indicated that the global usability of these tools is above the average. Results for all usability subscales were also above average wherein the highest scores were obtained for affect and efficiency, and the lowest scores were attributed to helpfulness and learnability. The findings suggest that CAT tool developers need to work further on the enhancement of the tool’s helpfulness and learnability to improve the translator’s experience and satisfaction levels. Further improvements are still required to increase the Arabic language support to meet the needs of Arab translators. Full article

Airborne laser scanning is a promising technique for efficient and accurate, remote-based forest inventory, due to its capacity for direct measurement of the three-dimensional structure of vegetation. The main objective of this study was to test the usability and accuracy of an individual tree detection approach, using reFLex software, in the evaluation of forest variables. The accuracy assessment was conducted in a selected type of multilayered deciduous forest in southern Italy. Airborne laser scanning data were taken with a YellowScan Mapper scanner at an average height of 150 m. Point density reached 30 echoes per m², but most points belonged to the first echo. The ground reference data contained the measured positions and dimensions of 445 trees. Individual tree-detection rates were 66% for dominant, 48% for codominant, 18% for intermediate, and 5% for suppressed trees. Relative root mean square error for tree height, diameter, and volume reached 8.2%, 21.8%, and 45.7%, respectively. All remote-based tree variables were strongly correlated with the ground data (R² = 0.71–0.79). At the stand-level, the results show that differences ranged between 4% and 17% for stand height and 22% and 40% for stand diameter. The total growing stock differed by −43% from the ground reference data, and the ratios were 64% for dominant, 58% for codominant, 36% for intermediate, and 16% for suppressed trees. Full article
