Comparison Utilization of UAV Images & Satellite Images for Geospatial Analysis

Abstract

The rapid advancements in remote sensing technologies have opened new avenues for geospatial analysis by providing high-quality imagery and data. Unmanned Aerial Vehicles (UAVs) and satellites have emerged as prominent tools for capturing Earth's surface information, each offering unique advantages and limitations. This paper presents a comprehensive comparison of the utilisation of UAV images and satellite images in geospatial analysis. The practical implications of employing UAVs and satellites in diverse scenarios include environmental monitoring, disaster management, urban planning, and agriculture. The benefits of UAVs, such as their ability to capture high- resolution images with precision and on-demand deployment, are contrasted with satellites' global coverage and consistent monitoring capabilities. Integrating UAV and satellite data is emphasized as a complementary approach to geospatial analysis. Techniques for fusing data from these sources are discussed, enabling the creation of comprehensive datasets that combine detailed local information from UAVs with broader context from satellite imagery.
