Geographic Information Systems in Agriculture

Local Resources Information System (LORIS)

• LORIS (Local Resources Information System) consists of various modules for data import and raster file generation.
• Capable of storing raster information in a database, producing digital agro-resource maps, and creating operational maps.
• A comprehensive farm GIS includes base maps indicating topography, soil type, nutrient levels (N, P, K), soil moisture, pH, and more.
• Data on crop rotations, tillage practices, nutrient/pesticide applications, and yields can be stored for analysis.
• GIS facilitates the creation of fertility, weed, and pest intensity maps, aiding in the formulation of efficient nutrient or pesticide application rates.

Application of Geoinformatics in Precision Agriculture

• Precision farming uses a systems engineering approach to optimize crop production with necessary inputs.
• This approach leverages innovations in technology, including microcomputers, GIS, remote sensing, and automatic machinery control.
• It manages spatial and temporal variability in agriculture based on integrated soil, plant, and engineering management technologies.
• Key software components include tools for geographic data manipulation, database management systems (DBMS), geographic query and analysis support, and a user-friendly graphical interface.
• The data is crucial, with geographic and related tabular data collected either in-house or through commercial providers.

Importance and Role of People in GIS

• GIS technology relies on skilled professionals for system management and real-world application solutions.
• Users range from technical specialists designing the system to everyday users benefiting from geographic data in their work.
• Successful GIS operations require well-defined plans and business rules unique to each organization.

Geodesy and Its Principles

• Geodesy, also known as geodetic engineering, involves measuring and representing the Earth's surface and gravitational field.
• It is the science behind mapping and measuring the Earth's dimensions and physical properties.
• Techniques from NEHM have been adapted to various crops and regions, with beta versions developed for maize and wheat across South Asia, China, Kenya, and Zimbabwe.

Spatial Data Management in GIS

• Geospatial data has a distinct structure focused on the identity, location, shape, and orientation of objects.
• Geographies use points, lines, tables, and polygons to represent objects, forming the tabular part of geospatial data.
• GIS effectively manages both structured and unstructured data (e.g., tagged raster imagery) for comprehensive mapping.
• Raw GIS data requires conversion into maps for human interpretation, showcasing GIS's capabilities.

Overview of Geographic Information System (GIS)

• A GIS is a computer-based tool for mapping and analyzing geographical events and entities.
• Integrates database operations like querying and statistical analysis with geographic visualization, enhancing decision-making across sectors.
• GIS outperforms manual mapping methods by providing quicker and more precise geographic analysis.

Operational Benefits of GIS

• Enables geographic queries and analysis for informed decision-making.
• Enhances organizational integration by facilitating access to spatial data.
• Improves strategic planning through efficient mapmaking and geographic event visualization.
