A comparison of GPS and manual calculations for measuring agricultural land

Abstract

This study compares the effectiveness of GPS technology and manual calculations in measuring agricultural land, focusing on their accuracy, efficiency, and suitability. The integration of soft computing tools like GPS and Google Earth Pro has streamlined the data collection and analysis process, offering a more automated and visually intuitive platform for land measurement. GPS technology provides significant advantages in speed and automation, making it ideal for large-scale land surveys. However, it is subject to limitations such as signal interference, equipment calibration issues, and high initial costs. In contrast, manual measurement methods, though time-consuming and labor-intensive, are cost-effective, reliable, and offer high accuracy, particularly for smaller agricultural lands where precision is critical. Through a detailed comparison of both methods, it was found that for smaller agricultural plots, manual calculations are preferred due to their accuracy, cost-effectiveness, and ability to handle complex land boundaries. Conversely, GPS is better suited for larger agricultural operations where the benefits of speed, automation, and scalability outweigh the initial investment and operational challenges. Ultimately, the choice between GPS and manual methods should be based on an evaluation of specific needs, budget constraints, and land characteristics. The study highlights that, by understanding the strengths and limitations of each method, agricultural professionals can make informed decisions to optimize land measurement practices and improve productivity.
