An archaeologist uses ground-penetrating radar to map a rectangular Inca settlement measuring 180 meters by 120 meters. The scanner captures data in 2-meter by 2-meter grids. If each grid requires 45 seconds to process and analyze, how many hours are needed to process the entire site?

# How Ground-Penetrating Radar Is Revolutionizing Inca Archaeology — A Deep Dive into a 180m x 120m Settlement When advanced scanning technology meets ancient history, something extraordinary unfolds — and right in the heart of the Andes, archaeologists are using ground-penetrating radar to map vast Inca settlements with precision once unimaginable. One recent project reveals a sprawling rectangular site stretching 180 meters by 120 meters, analyzed in 2-meter by 2-meter grids, transforming raw terrain into a digital blueprint layer by layer. With each grid demanding 45 seconds of processing time, how much time does the entire survey take? This isn’t just a technical question — it speaks to broader trends in cultural preservation, digital archaeology, and how modern tools reveal lost corners of human history. ## The Rise of Ground-Penetrating Radar in Archaeology Across the US and globally, ground-penetrating radar (GPR) is reshaping how researchers explore ancient sites. No longer limited to invasive excavation, GPR offers a non-destructive way to detect buried structures, pathways, and artifacts hidden beneath layers of earth. This is especially vital for sensitive archaeological zones like those in Peru, where preserving original contexts matters deeply. By mapping data in consistent grid patterns, archaeologists build comprehensive 3D maps that shed light on Inca construction, land use, and community patterns—without disturbing the site. This approach reflects a growing emphasis on science-driven, sustainable research methods.
