The history of GIS all started in 1854. Cholera hit the city of London, England. British physician John Snow began mapping outbreak locations, roads, property boundaries, and water lines.
John Snow’s Cholera map was a major event connecting geography and public health safety. Not only was this the beginning of spatial analysis, but it also marked the start of a whole field of study: Epidemiology – the study of the spread of disease.
To this date, John Snow is known as the father of epidemiology. The work of John Snow demonstrated that GIS is a problem-solving tool. He put geographic layers on a paper map and made a life-saving discovery.
Explanation:
It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
<h3>How are isotopes used in radioactive dating?</h3>
These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.
Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.
