The objective of this study was to monitor the reclamation development and assess the LULC changes in a reclaimed area in Upper Egypt. GIS and remote sensing-based multi-temporal Landsat imageries (i.e., Landsat-5 and Landsat-8; 30m) were utilized for mapping and analyzing the spatiotemporal dynamics between 2005 to 2020. Both supervised-based maximum likelihood classifier (MLC) and normalized difference vegetation index (NDVI)-based thresholds were implemented. The results of both methods were cross-compared and showed that the agriculture activities started in 2004 with small and sparse agriculture patches. The bare land occupied more than 65.1% of the total area between 2005-2008. Overall, using the MLC and NDVI-based classification, the authors observed an increase of approximately 455.6% (17,027.7 ha) and 477.2% (16,973.5 ha) over 15 years (2005-2020), respectively. The results could be very useful for assessing the success of the Egyptian strategies to sustain the agricultural land areas and food production through horizontal expansion and investment in the desert areas.

The capacity to reach surrounding areas from a location, commonly known as spatial accessibility, is crucial in the economic development of such a location. The Afram Plains in Ghana, despite been touted as the food basket of the country, has long struggled with poor spatial accessibility due to the lack of reliable transport infrastructure. This problem negatively impacts the movement of people and products, which ultimately hinders the economic development of the area. This research aimed at capturing the perspectives of Afram Plains' residents regarding their spatial access to nearby markets. A mixed-method approach comprising survey questionnaire, interviews, and geographic information system (GIS) was utilized. The results affirmed that movement within the area, particularly to market, is difficult. Again, due to limited transport facilities, many people resort to walking as their primary means of transportation. These findings are expected to provide some vital ideas for future road planning in the area.

A user-controlled navigation system is one of the important aspects of human-computer interaction. Finding best path from one location to another and navigating through that path has been a great concern in the geo-virtual navigation. Earlier studies on the geo-virtual navigation systems mainly focus on navigation and visualization, but lack in geo-spatial analysis. Geo-spatial analysis is the domain of geographic information systems (GIS) in which 3D geo-spatial information is used for navigation, geo-visualization, and geo-spatial analysis. The present study deals with wayfinding in the road network of the campus of National Institute of Technology (NIT) Hamirpur, India, in a hilly terrain. It facilitates perform various types of geo-spatial analyses on the road network and virtual travelling in a 3D space.

Monarch butterfly populations have been declining at an accelerating rate. While local mitigative measures can provide some relief, the larger scale loss of habitat and lack of flyway continuity must also be addressed. This study utilized a site suitability model to rank all locations within the Western monarch migratory zone in relation to factors that collectively attribute to butterfly viability, sustainability, and functionality. The two overarching study goals were to identify flyway gaps and to compare the model outcomes with geolocated butterfly sightings. The model weighed temperature, precipitation, elevation, and land cover/use factors based on their overall impact on site suitability. In addition to these factors, wildfires, solar farms, genetically modified crops, snow/ice cover, and open water were modeled as uninhabitable zones incapable of sustaining butterfly populations. The study results illuminated the heterogeneity of the Western monarch migratory range as well as raised questions regarding possible abnormal butterfly behaviors.

Currently, online maps are of the most innovative and significant sources of information in people's daily life. However, quality assessment of volunteered geographic information (VGI) data raises some challenges. This research aims to analyze the VGI participants' level of expertise through evaluation of their background information. Towards this goal, an android application was developed to test users' knowledge and cognition about some selected regions of city as well as their background information. In order to evaluate the quality of information expressed by participants, some changes were made in Tehran's online map, and users were asked to identify the changes and to guess the vanished attributes. Statistical and ANN approaches were applied for analysis. The results demonstrated that the ANN was able to predict the percentage of correct answers of a new volunteer with mean squared error of 0.2. This research suggests that users' age and familiarity with the specific region in the city play more significant roles in their expertise in using online maps and in probable participating in VGI.

Rapidly changing landscapes and disturbance regimes in the Global South impact the viability of conservation planning. Although conservation planning processes benefit from reliable multi-scale and multi-temporal data on landscape changes, this is not widely understood. In this paper, the authors examine landscape change dynamics and disturbance regimes in the Global South and discuss the methodological needs of characterizing pattern-process relationships of landscape disturbance to facilitate effective conservation planning. For example, geospatial analysis of Nairobi-Namanga Road, in the Kaputei Plains of Kenya, was used to highlight impacts of road infrastructure on wooded grassland and open grasslands, on wildlife migration corridors and livelihoods. The authors discuss how integration of geospatial technologies and landscape ecology metrics could enhance conservation planning and decision-making in the Global South. The benefits of coupling the decision-making process with stakeholder engagements and nature-based solutions to ensure viable conservation of biodiversity were also discussed.

The aim of this study is to introduce a method for estimating the population of a Middle Eastern city, the city of Hillah, in the absence of a census which was last conducted in 1997. The method incorporates the normalized difference built-up index and land use-land cover information to identify residential areas for four years 1987, 1997 (the last census), 2008, and 2018 using Landsat imagery. Dasymetric mapping is employed to rezone residential pixels to the city's administrative districts or mahallahs. Mahallah populations for each year are estimated using local and historical urban morphology characteristics combined with standardized housing and household sizes. The result of this study is a range of estimates for mahallah populations, but a reasonable estimate of the city of Hillah's population is developed. The use of historical information, urban design, and environmental data with remote sensing methods in a Middle Eastern context provides an added tool in the arsenal of population estimation techniques.

Region of Epirus located in NW Greece, is an area, that many landslides are recorded every year and earthquakes had impact in the infrastructures and human’s life in the past. In order to assess the seismic and the landslide risk, a susceptibility map was created and validated based on the landslide recordings, using the Rock Engineering System (RES) method, buffer zones were also created for each fault that was selected and calculations using empirical mathematical formulas were used to examine the potential as well as the maximum and the average ground displacement and finally a geodatabase was developed. The landslide susceptibility map and buffer zones were examined in relation to the proximity of the settlements, the road network and the cultural monuments of the area and many useful conclusions were exported, as an initial effort of recording the built environment that could potentially be vulnerable and affected.
