If the region to be mapped is 375 square kilometers, and she overlaps each image by 20% to ensure seamless stitching, how many distinct non-overlapping fragments must she initially capture, assuming each effective image contributes only 80% of its area due to overlap?

Okay, lets tackle this query. The user wants to understand how many distinct satellite images are needed to map a 375-square-kilometer region when each image covers 12.5 square kilometers, with 20% overlap to ensure seamless stitching—critical for accurate, high-resolution mapping. In today’s data-driven world, achieving clarity in geospatial technology is a growing priority. From urban planning to environmental monitoring, precise satellite mapping enables better decision-making—and this query reflects a core challenge professionals face in optimizing data collection workflows. Why Okay, lets tackle this query. The user wants to know how many distinct non-overlapping satellite images are required when mapping a large region with high-resolution images that overlap by 20%. This topic is gaining attention across U.S.-based industries relying on GIS and remote sensing—from infrastructure development to agriculture and climate tracking. With increasing demand for accurate spatial data, efficient image planning reduces costs and delays, making it vital for professionals exploring automation and optimization in geospatial work. How Okay, lets tackle this query. Each satellite image captures 12.5 square kilometers, but because of the 20% overlap, only 80% contributes usable, non-redundant data. To map 375 square kilometers with effective coverage per image, we calculate the number of distinct fragments needed. Subtracting overlap losses, each image effectively adds 10 square kilometers of new, usable area (12.5 × 0.8). Dividing total area (375 km²) by effective coverage yields 37.5 fragments. Since partial images aren’t practical, cartographers must round up to 38 initial images to ensure full, seamless coverage without gaps. Common Questions People Have About Okay, lets tackle this query. The user wants to know how many distinct satellite images must be captured when mapping 375 square kilometers with 12.5-km² images and 20% overlap. The answer combines spatial efficiency with practical workflow limits. Because each image contributes only 80% effective area, overlapping is essential for smooth stitching across larger areas. However, rounding up prevents undersampling—critical in professional mapping where precision matters. Questions often focus on how much overlap impacts final quality and how satellite imaging planning minimizes redundancy across mobile-first geographic projects.
