Geographic Information System (GIS) is a computer based system for collecting, storing, managing, analyzing and presenting geographic information and its associated data. GIS links real-world spatial elements (also known as feature data elements) to a coordinate system. These features can be separated into different map layers for decision–making. Common applications of GIS /GPS include: engineering mapping, automated photogrammetry, cadastral mapping, highway mapping, utility/facility mapping and management, surface water mapping, watershed prioritization, landuse planning and management, environmental impact studies and e-governance.
Application of Global Positioning System (GPS) technology and mapping tools to land related projects is becoming a widespread phenomenon. The advantages have proven substantial in improving access to information. The use of high, robust, technology such as GPS technology and mapping tools provide more simplification, increased efficiency, less cost, and sufficient accuracy. For efficiency, it is important to embrace advancement in technology use in agriculture. Technologies such as GPS and mapping models are valuable decision-making tools for land managers.
Decision makers and managers require accurate maps for decision-making. GIS provides a framework for gathering and organizing spatial data and related information so that it can be displayed and analysed. GIS gives you tools to analyze your data and see the results in the form of powerful, interactive maps that reveal how things work together, allowing you to make the most informed decisions possible.
Balancing the inputs and outputs on a farmland is fundamental to its success and profitability. The ability of GIS to analyze and visualize agricultural environments and workflows has proven to be very beneficial to those involved in the agricultural industry. From mobile GIS in the field to scientific analysis of production data on site, GIS is playing an increasing role in agriculture production helping farmers increase production, reduce costs, and manage their land more efficiently. While natural inputs in farming cannot be controlled, they can be better understood and managed with GIS applications such as crop yield estimates, soil amendment analyses, and erosion identification and remediation.
