GIS architecture encompasses the overall design and organization of a Geographic Information System (GIS).
The components of GIS architecture include hardware, software, data, people, and methods.
The architecture determines how these components interact and work together to create an efficient GIS system.
There are two main types of GIS architecture: client-server and web-based architecture.
In client-server architecture, GIS software runs on a server and is accessed by users through client computers.
The server is responsible for data storage, processing, and analysis, while the client is responsible for data visualization and user interaction.
Multiple users can work on the same dataset simultaneously, making it ideal for collaborative work.
In web-based architecture, the GIS software is accessed through a web browser, eliminating the need to install software on local machines.
The GIS data and software are stored on a server and accessed through a web interface, making it ideal for remote work and data sharing.
The hardware component of GIS architecture includes computer systems, storage devices, and input/output devices required to run and manage the GIS system.
The GIS software is the core component of the GIS architecture that enables users to capture, manage, analyze, and visualize geographic data.
The data component of GIS architecture includes various types of spatial and non-spatial data required to create and analyze maps.
The people component of GIS architecture includes GIS professionals, stakeholders, and end-users who use and maintain the GIS system.
The methods component of GIS architecture refers to the various techniques, procedures, and tools used to create, manipulate, analyze, and visualize geographic data.
The GIS architecture provides a framework for integrating the hardware, software, data, people, and methods to create a functional and efficient GIS system that meets the needs of the stakeholders.
Groundwater refers to the water that resides beneath the Earth's surface in the pores and crevices of rock, sediment, and soil. Two key properties that influence the movement and storage of groundwater are porosity and permeability: 1. Porosity: - Definition: Porosity refers to the volume percentage of void spaces (pores or openings) in a geological material, such as soil or rock. - Role: Porosity determines how much water a subsurface material can hold. It is a measure of the material's capacity to store water. - Factors: Porosity is influenced by the size and arrangement of particles within the material. Highly porous materials have more void spaces, while less porous materials have fewer. - Units: Porosity is expressed as a percentage, with 0% indicating complete solidity (no pore spaces) and 100% indicating complete void space. 2. Permeability: - Definition: Permeability refers to the ability of a geological material to transmit fluids, such as water. It meas
