This research article details the design and development of an Android-based application titled "GPS Land Area Calculator", aimed at providing precise measurement of land areas using Global Positioning System (GPS) technology. The application captures the user's geospatial coordinates in real time as they traverse the boundary of a given land parcel, and subsequently computes the enclosed area based on the recorded path.The primary objective of this study is to develop an efficient and accessible digital tool that facilitates accurate land area estimation for stakeholders such as agricultural practitioners, land surveyors, and real estate professionals. By eliminating the need for conventional sur- veying instruments and manual calculations, the application significantly reduces the time, cost, and expertise required for field measurements. Key features of the application include support for multiple units of measurement, persistent data storage, and user-friendly interaction design. The development process adhered to standard software engineering methodologies, encompassing requirement elicitation, system architecture design, implementation, validation, and performance evaluation. The application was implemented using the Java programming language within the Android Studio integrated development environment (IDE), and extensively tested across a variety of Android devices to ensure functional consistency, accuracy, and compatibility. Experimental results confirm that the GPS Land Area Calculator offers a high degree of precision and reliability in land area computation, thereby demonstrating its potential utility in agricultural management, geospatial surveying, and property assessment domains. Future work may focus on extending the system's capabilities through the integration of advanced functionalities such as topographical analysis, satellite imagery overlays, and cross-platform operability.
