Electromagnetic distance measurement (EDM) was first introduced in 1948 using visible light and later in 1957 using microwaves. While early models were bulky, EDM revolutionized surveying by enabling accurate distance measurements over long ranges day or night.

Sources of error include improper instrument use, faulty enviro
