A spatial decision support system is a solution for spatial issues and problems applying a computer system and providing results for decision making. This comprehensive review study has been carried out to determine GIS and RS in SDSS towards water quality modeling in Malacca River. Rapid development in land use for human activities include agricultural and livestock activities, industrial acti...

Soil erosion is one of the most serious environmental problems affecting the quality of soil, land, and water resources upon which humans depend for their sustenance. A soil erosion hazard map is highly useful for environmental planning, soil conservation and management in soil erosion prone areas. In order to assess the soil erosion hazard, remote sensing (RS) and geographical information syst...

GIS software development is now moving in the direction of components. The design of a two-dimensional GIS componentware – MapManager, which is based on the COM/DCOM technology, is introduced here. In the process of GIS software design, we should mainly consider the following aspects: spatial database design, visualization, data interface, spatial query and analysis, editing and mapping. At las...

In GIS, understanding the layout of interior spaces has important applications in the analysis of energy efficiency, indoor navigation and atmospheric pollution. However, detailed models of building internals are usually held in engineering or architecture software, including Building Information Modelling (BIM) software such as Autodesk Revit, and are not easily understood by GIS in this forma...

Remote Sensing as a direct adjunct to field, recently playing an important role in the study and assess the natural resource in any part of the world. Anthropogenic changes in land use and land cover and land use are often assumed to be identical, they are rather quite different. Land cover may be defined as the biophysical earth surface, while land use is often shaped by human, socio-economic ...

Domestic waste water treatment using Onsite Sewage Treatment and Disposal Systems (OSTDS) (also known as septic systems) is a source of nitrogen contamination in groundwater and surface water. Estimating nutrient load from septic systems as a storm water source to surface water bodies is important to reduce nutrient load in support of Total Maximum Daily Load (TMDL) programs. Software packages ...

Original scientific paper In recent years information technology has grown very rapidly. In the context of GIS, Free/Open source concept and also three-dimensional implementation have had more development too. The usage of these types of software is increasingly growing because of reasons such as security, open standards, vendor independence. In this regard, one of the most significant problems...

Land refers to the planet’s surface not covered by seas, lakes or rivers, but different types of vegetation (e [...]
