With the development and construction of the city, the urban development of the Macau Peninsula has entered an era of stock development against the background of the limited scale of urban land. With the shortage of land resources, the problem of unused land on the Macau Peninsula is coming to the fore. This paper mainly studies the problem of idle land in the Macau Peninsula, based on the urban development and particular historical background of the region, investigates and elaborates on its complex formation causes through the literature research method, and analyzes the spatial distribution characteristics of idle land in the current situation of the Macau Peninsula by using GIS technology. Based on the above research,suggestions are put forward to prevent and manage the urban vacant land problem in the future urban management and development of Macau.

Eco-efficiency is an invaluable indicator for the measurement of the relationship between production activities and environmental depletion. This study measures the tourism eco-efficiency of 30 provinces in China from 2005 to 2020 based on the super-efficiency SBM model, and explores its spatial-temporal evolution characteristics using the kernel density function, standard deviation ellipse, and center of gravity model. Then, the influencing factors of the tourism eco-efficiency in China are analyzed by Tobit regression model. The results show that the tourism eco-efficiency of China is generally fluctuating upwards, but has not yet reached the maximum production possibility frontier. The kernel density curve shows a unimodal-bimodal-unimodal pattern, while the inter-provincial differences have been decreasing and becoming more balanced. The center of gravity of tourism eco-efficiency is located at the junction of Henan and Hubei province and generally moves to the south (slightly to the southwest). Meanwhile, it is revealed that the level of economic development and the tourism eco-efficiency has a significant inverted U-shaped relationship. The level of economic openness, traffic conditions, and tourism eco-efficiency is positively correlated. The environmental regulations and industrial structure have a negative but limited impact on tourism eco-efficiency. Finally, recommendations and suggestions for policy formulation to promote quality and sustainable development of the tourism industry are put forward, such as increasing investment in ecological protection and governance in tourism development, improving capacity-building in allocating green and low-carbon technologies and resources, strengthening tourism infrastructure construction, and enhancing environmental governance systems and mechanisms.

Open space has various implications in urban development planning and has been integrated in recent urban planning approaches and practices in Nepal. The open spaces are not only important for (re)shaping the urban form but are also important for enhancing urban social life and disaster risk management, particularly for dense cities. As most of the cities in Nepal have been growing haphazardly, the cities lack sufficient open space. However, the value of open space in dense cities like Kathmandu has been recognized more after the Gorkha Earthquake 2015 as the open spaces were extensively used for risk relief, treatment, recovery, and rehabilitation during and after the earthquake. With this background, this paper presents the major planning initiatives in Nepal and discusses how recent urban plans have provisioned and initiated open spaces development by reviewing concurrent urban planning practices, particularly reviewing Periodic Plans, Integrated Urban Development Plan, Smart City Plan, and Land Development Plan. The development of open areas has not been given much attention in the earlier urban planning practice but recent urban development planning has emphasized with a special focus which is very important for sustainable and safer city development and is expected to address the current bulging urban issues of spatiality and sociability. Therefore, it is very important for integrating open space implications in city planning and such open space should be conceptualized according to the city’s geography, landscape as well as socio-cultural contexts.

Traffic volume information has long played an important role in many transportation related works, such as traffic operations, roadway design, air quality control, and policy making. However, monitoring traffic volumes over a large spatial area is not an easy task due to the significant amount of time and manpower required to collect such large-scale datasets. In this study, a hybrid geostatistical approach, named Network Regression Kriging,has been developed to estimate urban traffic volumes by incorporating auxiliary variables such as road type, speed limit, and network accessibility.Since standard kriging is based on Euclidean distances, this study implements road network distances to improve traffic volumes estimations.A case study using 10-year of traffic volume data collected within the city of Edmonton was conducted to demonstrate the robustness of the model developed herein. Results suggest that the proposed hybrid model significantly outperforms the standard kriging method in terms of accuracy by 4.0% overall, especially for a large-scale network. It was also found that the necessary stationarity assumption for kriging did not hold true for a large network whereby separate estimations for each road type performed significantly better than a general estimation for the overall network by 4.12%.

This paper traces the sixteenth-century addition and removal on maps of a bulge on the southern coast of Chile. Abraham Ortelius was primarily responsible for these changes and many cartographers followed his lead.Then, Ortelius rotated the coastline of Chile from northwest to north. Later, he dropped the latitude of the islands of San Pablo and Isla de los Tiburones down six degrees. He named the Amazon River “Río de las amazons.” Finally, he removed the cities with fake Native-American-sounding names along the Pacific coast of North America. The research underlying this paper examined over seven-hundred sixteenth-century maps made by sixdozen cartographers. This paper cites five-dozen maps by four-dozen cartographers. In the traceability section of this paper, this information was condensed into a traceability diagram, which shows the chronological flow of information among a score of cartographers. Using this information, this paper traced the influence of one cartographer on another: it showed who influenced whom. It showed the spread of knowledge. Ortelius was at the center of most of this knowledge explosion.
这篇论文追溯了16世纪智利南部海岸隆起的地图上的增减。亚伯拉罕·奥特利乌斯主要负责这些变化,许多制图师跟随他的领导。然后,奥特利厄斯将智利的海岸线从西北向北旋转。后来,他把圣巴勃罗岛和洛斯蒂布隆岛的纬度降低了6度。他将亚马逊河命名为“Río de las amazons”。最后,他删除了北美太平洋沿岸那些名字听起来像印第安人的城市。这篇论文背后的研究检查了76位制图师绘制的超过700张16世纪的地图。这篇论文引用了四打制图师绘制的五打地图。在本文的可追溯性部分,这些信息被浓缩成一个可追溯性图,它显示了在许多制图员之间按时间顺序的信息流。利用这些信息,本文追踪了一位制图师对另一位制图师的影响:它显示了谁影响了谁。它显示了知识的传播。奥特利乌斯是这种知识爆炸的中心。

Landuse/Landcover (LULC) changes are recognised as some of the major causes of environmental problems like land degradation and climate change. To achieve sustainability, we need to properly understand such changes in order to have adequate information that will enable us to design and implementing measures to mitigate their negative impacts. Doing this particularly requires a proper understanding of how stakeholders perceive the changes in general and their drivers in particular. Unfortunately,not much is known for many areas about the perspective of landuse stakeholders on drivers of LULC changes. This paper reports the results of a study conducted to examine the perceptions of different landuse stakeholders on drivers of LULC changes in Abuja Federal Capital Territory, Nigeria.Questionnaire survey was utilised, involving 514 households across four settlements, 2 rural (Karshi and Orozo) and 2 urban (Nyanya and Karu) towns in the territory, which were complimented with Focus Group Discussions were conducted. The results obtained showed that urban dwellers are largely aware of drivers of changes in socioeconomic drivers (physical development on lands, more commercial complex development and more institutional development). Rural dwellers are largely aware of environmental drivers of LULC changes (bush burning, livestock overgrazing, collections of wood and medicinal plants,and agricultural expansion). It was concluded that there is the need to bring about a harmonisation of the perceptions of LULC change drivers by the rural and urban dwellers so as to bring about a common front understanding and responding to LULC changes in the study area.

Progressive population concentration to the urban centres has fuelled urban expansion in both horizontal as well as vertical direction, consequences in the urban landscape change. This growth resulted in posing many complexities towards sustainable urban development which can be counted by observing the changing proportions of natural landscapes and built up areas. Local climate zones (LCZs), a systematic classification of natural lands and built up lands, are identified in Siliguri Municipal Corporation (SMC) and its surrounding region to explore the spatio temporal complexity of urban growth in recent years. Rapid urbanization and population growth of SMC have led to change the building states from low rise to mid and high rise which added an important feature to the urban landscape dynamics of the area. The work intends to provide the vision of spatial urban morphology of the area through investigation of its changing land use and changing urban built space using the LCZ classification. The study shows that the WUDAPT method can accurately generate LCZs, especially the built type LCZs. The results of the proposed LCZ classification scheme are tested using error matrix for the year 2001 and 2021 having coefficient values of 0.79 and 0.81 respectively. The study explores the changing pattern of building states of SMC using LCZ products, which is essential for proper urban planning implementations.

This paper describes the process of designing models and tools for an automated way of creating 3D city model based on a raw point cloud.Also, making and forming 3D models of buildings. Models and tools for creating tools made in the model builder application within the ArcGIS Pro software. An unclassified point cloud obtained by the LiDAR system was used for the model input data. The point cloud, collected by the airborne laser scanning system (ALS), is classified into several classes: ground, high and low noise, and buildings. Based on the created DEMs, points classified as buildings and formed prints of buildings, realistic 3D city models were created. Created 3D models of cities can be used as a basis for monitoring the infrastructure of settlements and other analyzes that are important for further development and architecture of cities.
