Abstract

Cadastre is a land information system based on land parcels. The growth in the number of land parcels is influenced by the increasing conversion of land into residential areas, which in turn is driven by several factors, oneof which is population growth. The demand for housing initially expanded horizontally; however, due to limited landavailability, it has now shifted toward vertical development. Vertical housing types such as flats or apartments are emerging, which introduce complexity into the cadastral system due to the partitioning of internal spaces. Cadastrerequires high-accuracy measurements; hence, the increase in measured areas leads to a higher workload. The SLAM (Simultaneous Localization and Mapping) method offers a breakthrough in fast and accurate measurements usinglaser-based technology, which can be implemented in cadastral mapping to update spatial data precisely and efficiently. This method combines the flexibility of handheld operation with high data precision by employing denselaser scanning. This study utilized the SLAM method, resulting in a polygon area processing of 0.3558 m², with anaverage center-point distance deviation of 0.0658 m, a polygon circularity ratio of -0.002, and a regression value of less than 10%. When this model is applied with a tolerance of up to 10% spatial error, it can achieve verticalmeasurements up to the 43rd floor, in accordance with the Directorate General of Taxation Circular and tested basedon ISO 19113:2011 standards.

Abstract

The northern coast of Java Island (locally known as Pantura) is a strategically important area, particularlyin the distribution sector. However, its topographical characteristics and proximity to the Java Sea make it vulnerableto the threat of tidal inundation. Moreover, environmental factors such as sea level rise, land subsidence, and coastalabrasion further exacerbate its susceptibility to flooding. The phenomenon of tidal inundation, locally referred to asrob, occurs when seawater overflows onto low-lying coastal areas during high tides. The rob phenomenon significantlyimpacts the socio-economic conditions of coastal communities, disrupting daily activities and damaging criticalinfrastructure. This study simulates potential inundation using a uniform Highest High Water Level (HHWL) scenarioof 1.2 meters to estimate flood depth and spatial extent. The modeling approach applies a consistent water surfaceelevation across the study area, without considering storm surge and hydrodynamics, resulting in generalizedinundation patterns. The methodology follows the Technical Guidelines for Disaster Risk Assessment issued byIndonesia’s National Disaster Management Agency (BNPB) and integrates various spatial datasets, including landcover data from Sentinel Land Cover by ESRI, topographic data from the Shuttle Radar Topography Mission (SRTM)Digital Elevation Model (DEM), and maximum tidal height data processed using the Admiralty method. The analysisshows that, assuming a Highest High Water Level of 1.2 meters, Kendal Regency, Brebes Regency, and SemarangCity are the most affected areas in terms of both flood depth and extent. The inundated areas are estimated at 3,744.91hectares in Kendal Regency, 2,880.58 hectares in Brebes Regency, and 513.17 hectares in Semarang City. Thissituation could become more severe in the event of storm surge, extreme weather, or climate anomalies if timely andeffective mitigation measures are not implemented. These findings are expected to provide a strong foundation forpolicymakers to formulate targeted, data-driven, and sustainable mitigation strategies to protect communities andinfrastructure along Java’s northern coastal region.

Abstract

Existing scholarly literature on the Gaussian Splatting algorithm has predominantly concentrated on improving the rendering and reconstruction of three-dimensional objects, as well as exploring its applications in various academic disciplines, such as medicine, robotics, and mapping, while being limited to local coordinate systems. This study describes the development of a 3D scene modelled using the Gaussian Splatting algorithm, featuring accurate distance and position geometry based on three.js. The developed 3D scene was then evaluated with precise position and distance coordinates in the field and compared to the established SfM-MVS (Structure from Motion-Multi View Stereo) algorithm. The findings demonstrate that the proposed development successfully generated three.js-based 3D scenes with global coordinate compatibility, utilising the Gaussian Splatting algorithm, achieving the same level of position and distance accuracy as the SfM-MVS algorithm, with a 95% confidence level using a T-test. This research concludes that the developed approach is successful and can be further expanded for various scientific fields that require accurate position and distance information using the Gaussian Splatting Algorithm.
