Low-cost lidar sensors mounted on unmanned aircraft systems (UAS) can be applied for the acquisition of small-scale forestry applications providing many advantages over airborne laser scanning (ALS), such as flexibility, low flight altitude and small laser footprint. Compared to 3D data generated from dense image matching using photogrammetry, lidar has the advantage of penetration through the canopy gaps, resulting in a better representation of the vertical structure of the vegetation. We analyse the effect of different flight altitudes on the penetration rate of heathland vegetation in the Blue Mountains, Australia using a Phoenix system based on a Velodyne Puck 16 scanner and a GreenValley LiAir X3-H system based on a Livox scanner. The different sensors achieve quite different performances, especially for the mid-vegetation layer between the canopy and the ground layer. Representation of this layer is especially important when investigating fuel availability for bushfire analyses. In this layer, the LiAir system achieves a sufficient picture at an altitude of 65 m above ground, whereas the Phoenix system needs to be flown as low as 40 m to get a comparable result.

Point cloud data acquired via laser scanning or stereo matching of photogrammetry imagery has become an emerging and vital data source in an increasing research and application field. However, point cloud processing can be highly challenging due to an ever-increasing amount of points and the demand for handling the data in near real-time. In this paper, we propose an efficient in-memory point cloud processing solution and implementation demonstrating that the inherent technical identity of the memory location of a point (e.g., a memory pointer) is both sufficient and elegant to avoid gridding as long as the point cloud fits into the main memory of the computing system. We evaluate the performance and scalability of the system on three benchmark point cloud datasets (e.g., ETH 3D Point Cloud Dataset, Oakland 3D Point Cloud Dataset, and Kijkduin 4D Point Cloud Dataset) w.r.t different point cloud query patterns like k nearest neighbors, eigenvalue-based geometric feature extraction, and spatio-temporal filtering. Preliminary experiments show very promising results in facilitating faster and more efficient point cloud processing in many potential aspects. We hope the insights shared in the paper will substantially impact broader point cloud processing research as the approach helps to avoid memory amplifications.

Given the importance of identifying Land Covers (LC) for various fields of study, such as the environment and natural disasters, work has been going on to develop tools and sources that provide information on them. In this sense, it is possible to obtain spatial information about LCs with satellite images. In order to obtain said spatial information, it is necessary to extract and determine a set of characteristics that can best describe and infer differences between types of coverage. In this article, an analysis and selection of semivariogram characteristics is carried out to describe the spatial variation in the textures of CTs. The selection of characteristics improves the identification of TC types and the performance of semantic segmentation methods in satellite images. The images used for the analysis experiments corresponded to multispectral satellite images from the Sentinel 2 satellite of COPERNICUS of the European Space Agency (ESA) and Landsat 8 of the United States Geological Survey (USGS). Semivariograms and their characteristics for patches of different TCs (agricultural vegetation, vegetation, soil, water, and urban) were obtained. In addition, coefficients of variation of the characteristics in the semivariograms were analyzed between different and the same hedges. Finally, relevant characteristics were selected considering the behavior of the coefficient of variation and those obtained with the Relieff algorithm.

Traffic incidents have emerged as a major public health and safety concern, causing significant fatalities and injuries in the Region of the Americas. This issue is highlighted by the World Health Organization (WHO) (2018), indicating 1.35 million annual traffic-related fatalities globally, with Mexico reporting 12.9 deaths per 100,000 inhabitants. The COVID-19 pandemic has further influenced urban mobility patterns, with a surge in delivery vehicles due to increased online commerce. Despite reduced overall mobility, traffic incidents persist, necessitating a thorough assessment of their current state in Mexico City. Real-time data on traffic events is crucial for identifying high-risk areas and formulating safety measures. This study aims to construct an explanatory model for road accidents in Mexico City from 2018 to 2022, utilizing multiple regression analysis to identify spatio-temporal patterns. The findings are intended to inform policymakers on strategies to enhance road safety.

Digital twins have gained increasing attention as a tool to facilitate decision-making in the cities. However, the current discourse predominantly focuses on technical aspects while overlooking the human aspect in urban digital twins. This work proposes a conceptual framework that addresses the role of humans in relation to the urban environment, therefore highlighting the social value of urban digital twins. The proposed framework is subsequently implemented in a specific case study of outdoor walking comfort at National University of Singapore, validating its feasibility in practice. By incorporating human sensing data, such as participatory data, urban digital twins have the potential to represent the dynamic interaction between people and environments, generating a holistic physical-social-virtual system.

The border shared by Mexico and Guatemala, formed by the states of Chiapas, Campeche, Tabasco and the Guatemalan country, is located in one of the largest existing border basins in Mexico. This basin has a highly complex hydrological network, and the topographic variability, as well as the large amounts of precipitation, make it one of the most important areas in the world for its biological and cultural diversity. This diversity is threatened by land use and cover change, where there are series of drivers of change and environmental and social determinants that make their analysis a priority. This study analyzes historical land use changes that have occurred since 1990 and 2010, which are used as the basis for the construction of a prospective trend model for the year 2030. The results obtained from the prospective trend model show that dramatic changes are expected for the Usumacinta watershed in terms of increased agricultural land use, loss of forests and loss of water bodies. This information shows the need to analyze the socio- environmental implications that this could bring with it, as well as the importance of building instruments to focus the means of territorial intervention.

This paper introduces a new plug-in for QGIS that allows to connect to the free and open-source 3D City Database to load CityGML data, structured as classic GIS layers, into QGIS. The user is therefore not required to be a CityGML specialist, or a SQLexpert, as the plug-in takes care of hiding from the user most of the complexity in terms of underlying data model and database schema implementation. The user can therefore load CityGML thematic "layers" (e.g. for buildings, bridges, vegetation, terrain, etc.), explore their geometries in 2D and 3D and access and edit the associated attributes. At the same time, depending on the user privileges, it is possible to delete features from the database using either normal QGIS editing tools, or a "bulk delete" tool, also included. The plug-in is composed of two parts, a server-side one, whichmust be installed in the 3D City Database instance, and the client-side one, which runs as a QGIS plug-in in strict sense. A GUI-based tool is also provided for database administrators in order to install/uninstall the database-side part of the plug-in, and manage users and their privileges. All in all, the 3DCityDB-Tools plugin facilitates the access to CityGML data for GIS practitioners from heterogeneous fields and expertise with the common denominator being the well-known QGIS environment.

This paper discusses the reconstruction of LoD2 building models from 2D and 3D data for large-scale urban environments. Traditional methods involve the use of LiDAR point clouds, but due to high costs and long intervals associated with acquiring such data for rapidly developing areas, researchers have started exploring the use of point clouds generated from (oblique) aerial images. However, using such point clouds for traditional plane detection-based methods can result in significant errors and introduce noise into the reconstructed building models. To address this, this paper presents a method for extracting rooflines from true orthophotos using line detection for the reconstruction of building models at the LoD2 level. The approach is able to extract relatively complete rooflines without the need for pre-labeled training data or pre-trained models. These lines can directly be used in the LoD2 building model reconstruction process. The method is superior to existing plane detection-based methods and state-of-the-art deep learning methods in terms of the accuracy and completeness of the reconstructed building.

Identifying and geolocating the diverse, even contrasting interests, needs and concerns of highly heterogeneous urban populations is challenging. In this research, we used social media (i.e., Twitter) and census data to assess the topics discussed by the inhabitants of the continuous urban area of Mexico City, Mexico and its surroundings around the 2021-2022 New Year's Eve period. We applied bot filters and undertook text cleaning to control the reliability of our data. Furthermore, we implemented topic modeling to identify the themes discussed. Finally, we assessed the relationship between Twitter activity and content and total population and marginalization at the municipality scale. Socially and environmentally relevant topics such as LGBTQ+, politics, vaccinations, women/feminism, air transport, cycling, healthcare/medicine, and public transportation were present in the digital urban conversation. People who are more marginalized displayed lower activity on Twitter and less diversity of topics. Moreover, there is high spatial clustering between the main topics discussed at the municipality level. Topics such as vaccinations, reading/literature and computers/smartphones are mainly discussed in areas with low marginalization, while racism/race, public transportation and money/finance are frequent in municipalities with a high proportion of marginalized inhabitants. Our results show the plausibility of the use of social media data to identify and geolocate the diverse interests and concerns of urban citizens based on first-hand information. Moreover, this approach may provide insights for decision making for urban policies, informing on location-specific social and environmental issues related to particular social groups.

The number of clandestine burial sites and clandestine graves in Mexico has increased considerably in recent years, associated with the increase in homicides and missing persons. This study aims to identify similarities and differences between municipalities in terms of clandestine graves, homicidal violence and missing persons, through cluster analysis, as well as to identify some significant environmental variables, such as airports, ports, borders, and roads through multivariate analysis. Access to sufficient data to study clandestine graves is complex, but this work achieves a count by municipality for 2012-2018. The results help to identify municipalities and continuous sets that could be considered a priority for public policy measures especially, coordination strategies between states and/or municipalities.
