Abstract

The development of spatial data utilization has increased dramatically in the past decade. This is related to the widespread use of Geographic Information Systems (GIS) and the advancement of technology in acquiring spatial data. High-tech tools like UAVs (Unmanned Aerial Vehicles) are increasingly integrated with Geographic Information Systems (GIS) and other surveying and mapping technologies, and are therefore used in various surveying, mapping, and spatial analysis projects. One of the advantages of UAVs is that the captured data can be processed through software, producing images with high spatial and temporal resolution. The use of this technology demonstrates that mapping can be performed using photographic data. The purpose of this research is to analyze and map the distribution of cultural tourism sites in detail using UAV and GIS in Nagari Tuo Pariangan, Tanah Datar Regency. Based on the results of the research, it can be concluded that data collection was carried out using a DJI Mavic Pro drone, capturing 228 aerial photos which were then exported into orthophotos. Orthophotos function as a reference for the distribution map of cultural tourism sites. In addition, a database was created, integrating spatial (geographic) and non-spatial (attribute) data, containing the necessary information for tourism objects, such as the owner's name, year of construction, function, and history of the object. There are 31 cultural tourism objects in Nagari Pariangan, Tanah Datar Regency, consisting of 8 Rumah Gadang (traditional houses), 11 Surau (small mosques), 3 hot spring pools, 3 stone inscriptions, 1 hot spring pool, 1 Tuo Pariangan Mosque, 1 river, 1 Tabuik Mosque, and 1 Saruang Hall. Most of these cultural tourism objects are well-maintained by their owners, while a small number are neglected due to a lack of adequate human resources.

Abstract

Sungai Pagu District has rich natural and cultural tourism potential, but its management has not been optimal due to a lack of community involvement, limited budget, and insufficient human resources in the tourism sector. With the development of Geographic Information System (GIS) technology, it can be utilized in various survey, mapping, and spatial analysis projects. This study aims to analyze the tourism potential and determine the priority for developing tourist attractions in Sungai Pagu District using the Analytical Hierarchy Process (AHP) approach. The criteria used include Tourist Attractions, Facilities, Accessibility, Infrastructure, and Management, with alternatives being natural and cultural tourism. Data were collected through documentation, interviews, questionnaires, and observations, and then analyzed using Microsoft Excel software. The research findings show that there are 3 natural tourist attractions and 5 cultural tourist attractions. Based on the evaluation of 5 criteria, Management received the highest score (58.23%). Among natural tourism, Embung Batu Anyuik is the top priority (67.15%), while among cultural tourism, Menara Songket ranked the highest (40.67%).

Abstract

Changes in land surface temperature are one of the important indicators in monitoring global environmental change. In the last decade, increasing surface temperatures have become a global concern, as they have the potential to affect ecosystems, air quality, water availability and human health. In addition, increasing land surface temperature also has a direct impact on the urban heat island phenomenon, which can worsen environmental conditions in urban areas. In this context, analyzing periodic changes in land surface temperature is important to understand the patterns and factors that influence these changes. The objectives in conducting this research, namely: Analyzing the land surface temperature, Creating a regional land surface temperature map and Analyzing changes in land surface temperature from the land surface temperature map of Pariaman City in 2015, 2019, and 2023. Based on the results of the analysis of changes in land surface temperature using Landsat 8 OLI/TIRS images in 2015, 2019, and 2023, it was found that there were significant variations in temperature changes in several areas. Landsat 8 image data is processed through several stages, starting from converting Digital Number (DN) values to spectral radians, brightness temperature, to estimating Land Surface Temperature (LST) in Celsius units. The analysis shows that there was a significant increase in land surface temperature during the period, especially in urban and coastal areas. In 2015, the majority of areas had temperatures of 20°C-24°C, while in 2019 it shifted to 24°C-28°C, and in 2023 it was dominated by temperatures of 28°C-32°C and above 32°C. These changes reflect a significant local warming trend, influenced by human activities and land use change. This research is expected to contribute to the understanding of environmental dynamics and support spatial planning that is more adaptive to climate change.

Abstract

Drought is a hydrometeorological disaster that significantly affects water availability and agricultural activities. Pesisir Selatan Regency has diverse topographic conditions that influence the level of vulnerability to drought, thereby requiring a comprehensive spatial analysis. This study aims to map drought risk by integrating slope steepness with other biophysical parameters using Geographic Information Systems (GIS). The data employed include slope maps derived from DEMNAS, rainfall data (CHIRPS 2024), soil types, land use, and river networks. The analysis was conducted through scoring and overlay methods to produce a drought risk map. The results indicate that areas with very steep slopes (>45%) have a high level of vulnerability due to surface runoff dominance and low infiltration capacity, particularly in Bayang Utara District. In contrast, flat to gently sloping areas dominated by rice fields and forest cover are relatively low-risk. Overall, drought risk in the region is classified into three categories: low, medium, and high. The resulting maps can serve as a basis for local governments in developing spatial planning policies, water conservation infrastructure, and disaster mitigation strategies that are more adaptive and sustainable.

Abstract

Tiku Beach in Tanjung Mutiara District, Agam Regency, West Sumatra is a 12.77 km coastal area experiencing continuous shoreline changes due to abrasion and accretion. This study aims to identify and map shoreline changes and calculate the area of abrasion and accretion in 2014, 2019, and 2024 using the Modified Normalized Difference Water Index (MNDWI) method based on Landsat 8 OLI satellite imagery. The MNDWI method utilizes the reflectance difference in the Green band (Band 3) and SWIR band (Band 6) to automatically separate the land-water boundary. Shoreline change analysis was performed using Net Shoreline Movement (NSM) and End Point Rate (EPR) methods through ArcGIS 10.8 software with the Digital Shoreline Analysis System (DSAS) extension. Analysis of 336 transects shows that accretion is more dominant than abrasion along Tiku Beach. The largest accretion was recorded at transect 230 with an NSM value of 71.3 m and an EPR rate of 7.12 m/year, while extreme abrasion occurred at transect 249 with an NSM value of -121.67 m and an EPR rate of -12.15 m/year. The evolution of the shoreline shows that in 2014 the coastline was still relatively stable, then in 2019 mild abrasion occurred in the west along with accretion in the east, and by 2024 this pattern became more pronounced. The results of this study are expected to serve as a scientific basis for decision-making in coastal disaster mitigation planning and sustainable coastal management in Agam Regency.

Abstract

Three-dimensional (3D) modeling has become an effective approach for documenting and measuring object dimensions in various geospatial applications. This study aims to evaluate the dimensional accuracy of 3D models generated using GNSS Visual RTK and Handheld SLAM LiDAR, with Total Station measurements used as the reference data. The research was conducted through field data acquisition using both technologies, followed by 3D model reconstruction and dimensional measurements on several parts of the building object. Dimensional accuracy was evaluated by comparing object dimensions and calculating the Mean Absolute Error (MAE) and percentage error. The results show that both technologies are capable of producing 3D models that accurately represent the dimensions of the object. However, GNSS Visual RTK demonstrated higher dimensional accuracy than Handheld SLAM LiDAR for most measurement parameters. These findings indicate that GNSS Visual RTK is more suitable for applications requiring high dimensional accuracy, whereas Handheld SLAM LiDAR offers advantages in faster data acquisition and more efficient mapping of larger areas.
