By • • Public, Research, Teaching • , , , , • 11 minutes of reading

Geographically Weighted Regression (GWR) is a spatial statistical method used for predicting outcomes based on geographical data. To conduct prediction using GWR, you can follow these steps: Note: It is essential to validate the GWR results with independent validation data and assess the model performance using appropriate validation metrics. Geographically Weighted Regression (GWR) is a powerful statistical tool for predicting outcomes based on geographical data. Its ability to account for spatial heterogeneity in the relationships between independent and dependent variables makes it an attractive alternative to traditional regression methods such as Ordinary Least Squares (OLS). The quality of GWR results […]

By Shahabuddin Amerudin Introduction A web map-based cemetery system typically utilizes a GIS (Geographic Information System) to display a map of the cemetery and the location of graves within it. Users can interact with the map to zoom in and out, pan around, and view detailed information about individual graves, such as the name of the deceased, date of birth and death, and other relevant details. Some systems may also include photographs of the graves, and allow users to search for graves by name or other criteria. For cemetery managers, this type of system can be useful for maintaining accurate

Inroduction Green Building Index (GBI) is a certification system developed in Malaysia, it is used to assess the environmental performance of buildings in the country. The GBI was created by the Malaysia Green Building Confederation (MGBC) in 2009 as a national green building rating tool to promote sustainable building design and construction practices in Malaysia. The GBI rating system assesses the environmental performance of a building based on six categories: Energy Efficiency and Conservation, Indoor Environmental Quality, Material and Resources, Site and Infrastructure, Water Efficiency and Innovation in Design. Buildings are evaluated based on specific criteria within each category, and

Space Demand Analysis for Muslim Cemeteries: Methods, Techniques, and Expectations

By • • Knowledge, Personal, Project, Public, Research, Teaching • , , , , , , • 26 minutes of reading

Introduction Space demand analysis is a critical process that helps organizations, developers, and architects to determine the amount of space needed for a particular function or activity. The process involves identifying the space requirements of an organization, project, or event, and then determining the amount of space necessary to meet those requirements. This analysis is important for ensuring that the space is efficient, functional, and cost-effective. Space demand analysis for cemeteries is a process used to evaluate the amount of land and burial plots needed to accommodate the deceased. It involves identifying the space requirements of a particular cemetery, and

Flood Detention Basin: Techniques for Identifying Suitable Locations and Measuring Analysis Accuracy

By • • Knowledge, Project, Public, Research, Teaching • , , , , • 23 minutes of reading

A flood detention basin is a man-made structure designed to temporarily store stormwater runoff in order to reduce the risk of downstream flooding. The basin typically includes a depression or pond that can hold water during a storm, along with an outlet or spillway that slowly releases the water once the storm has passed. These basins are typically found in urban areas, where they can help to manage the increased volume of runoff caused by impervious surfaces such as roads, buildings, and parking lots. The basin is designed to hold a certain volume of water, known as the “detention volume,”

Exploring the Replacement of Malay Reserve Land in Malaysia: Analysis of Successful and Unsuccessful Cases and the Role of GIS

By • • Knowledge, Personal, Project, Public, Research • , , , • 15 minutes of reading

Replacement of Malay Reserve Land refers to the process of replacing land that has been designated as reserve land for the Malay community with alternative land that can be used for other purposes. This process can occur for a variety of reasons, including the development of infrastructure projects, urbanization, and changes in land use patterns. One of the main reasons for the replacement of Malay Reserve Land is the development of infrastructure projects. These projects, such as highways, airports, and housing developments, often require large tracts of land, and if that land happens to be designated as reserve land for
