Abstract When it came time to produce the map, the entire district of Ampang Jaya was chosen as the area for the research. These two approaches gave very different results in terms of accuracy. The results of the map were categorised using a range of different classification techniques, some of which include Natural Breaks and Equal Interval, respectively. Various landslide susceptibility hazard zoning results were found when the two different classification systems were applied to the data. These zoning areas need to go through an accuracy assessment process in order to be validated. The accu

Abstract:

Abstract. Groundwater serves as a crucial source of drinking water, supports agricultural irrigation, and sustains aquatic ecosystems. However, contamination of groundwater poses significant risks to public health, food security, and ecological balance. Given that groundwater contributes an average of 40 % of California's water supply, ensuring its quality is of paramount importance for the state's municipalities, industries, and agricultural sector. To address this, rigorous groundwater quality assessment and monitoring are imperative to promote sustainable and safe utilization of these resou

Abstract:

This study assessed flood hazards in the Greater Jakarta area, Indonesia, using geospatial analysis and the weighted overlay method in a Geographic Information System (GIS). There are variables used, which are vegetation index, wetness index, Topographic Position Index (TPI), distance to water bodies, and altitude. The classification results showed five levels of hazards: very low (0.48%), low (1.60%), medium (28.70%), high (48.96%) and very high (20.26%). A total of 69.22% of the study area of 6,724.18 km² was classified as high to very high. The findings emphasise the need for risk-based zon

Abstract:

The phase of complex signals is wrapped since it can only be measured modulo-2; unwrapping searches for the 2-combinations that minimize the discontinuity of the unwrapped phase, as only the unwrapped phase can be analyzed and interpreted by further processing. Weighted least squares phase unwrapping algorithm could avoid errors transmission in the whole phase images, but it could not avoid defect and overlay of interference fringes caused by topographic factors. Therefore, a new phase unwrapping and weights choosing method based on local phase frequency estimate of topographic factors was pre
