“…Terrestrial Laser Scanning (TLS) is used in land surveying to capture detailed information about the terrain and ground characteristics [13]. It functions as a terrestrial version of Light Detection and Ranging (LiDAR), producing point clouds that encompass a horizontal coverage of 180° and a vertical coverage of 270° [14]. This scanning process enables the collection of precise data about the landscape and its features.…”

Terrestrial Laser Scanning (TLS) and Close-Range Photogrammetry (CRP) are advanced techniques for capturing 3D data in crime scene reconstruction, offering complementary information. Despite taking multiple scans and images from different angles to ensure a comprehensive model, limitations, such as device positioning, shadows, object distance, and laser beam angles prevent the creation of a complete crime scene model. Therefore, combining TLS and CRP data is crucial for achieving a comprehensive reconstruction. This study aims to transform a physical crime scene into a geospatial-based reconstructed model known as point clouds. The technique used was highly rich in realistic features, digitally reconstructed from TLS and CRP. The data sources were then fused via a rigid body transformation, creating a comprehensive crime scene model. The combined point cloud measurements were compared with measurements obtained from a high-precision Vernier caliper to ascertain their accuracy. The resulting Root Mean Square (RMSE) difference between the fused point cloud data and the high-precision caliper measurements was approximately ±4mm. The fusion of TLS and CRP data provides reliable and highly accurate 3D model point clouds, making it suitable for forensic applications.

“…GIS can be applied to a wide range of fields, such as the environmental disasters, sustainable energy, endemic control, agriculture, health, urban planning, demographic survey, and traffic (CHINGOMBE et al, 2015;CRISTEA, JOCEA, 2015;YASOBANT et al, 2015;ABDELRAHMAN, NATARAJAN, HEGDE, 2016;GUPTA et al, 2016;HASHIMOTO et al, 2016;JEMAL, AL-THUKAIR, 2016;NORTH, MILLER, 2017). Regarding traffic, the most important are research on accidents and route optimization (IVAN et al, 2015;ELSHEIKH et al, 2016).…”

considering the high rates of traffic accidents, care provided to victims must be fast and efficient. The objective was to analyze the density of traffic accidents and the profile of the victims assisted by the 4th Fire Department in Cascavel. It was also intended to analyze traffic signs and a place to build a new Fire Station. Geographic Information System and geoprocessing resources were used to identify the traffic accidents hotspots applying kernel density estimation. The victims' profile and their association with the severity of the injuries were obtained based on the chi-square statistic and the correspondence analysis. Field data were investigated to verify traffic signs at accident locations that involved victims with severity of more serious injuries. Most accidents occurred in the afternoon, involving men between 18 and 30 years old. Running over was the occurrence that most stood out considering the severity of the victims, with locations without any traffic signs. Moreover, a plot that meets all the requested criteria and is located in a region of high occurences of traffic accidents was found to build the new station.
