A infrared satellite imagery can locate items at ground-level or can detect differences in soil about one foot under the surface. These advancements can aid in discovering ancient civilizations by locating where the soil in the ground differs from the rest, revealing roads, villages, and tombs. (Source #3, Paragraph 2). This form of technology has not only aided in locating ancient civilizations but reveals numerous amounts of historical information. In one of the first trials of the satellite researchers found a 3,000 year-old city in Egypt. From above the ground this city looked like "a …show more content…
One of the weaknesses is that the image does not instantly reveal a discovery. Another weakness is that the satellite is useless in tropical forests because "Infrared cannot penetrate the dense canopy of the trees." (Source #3, Paragraph 6). Other inventions, such as The Mailbox are indeed very useful. This invention created by Mel Fisher is used to sweep long strips of sand on the ocean floor to discover objects and shipwrecks.(Source #1) Although this is very useful for the ocean, infrared satellite imagery is useful for land. The last con is the fact that the satellite is only really useful when used for land disoveries, while other inventions are dominating ocean
