Document Summary
Science involves understanding error theory, measurement and math techniques to accuracy, reliability. Art is understanding most efficient methods for obtaining measurements required. George washington, thomas jefferson, abe lincoln, teddy roosevelt (roosevelt was not a. Benefits: cost-effective, no power source, more suitable for outdoors, availability. Laser distance meter - measure distance (most suitable for indoor measurements) Total station - can do all other equipment"s work. Measure, then allow total station to do computations. Indirect vs direct s to analyze field data, ot a surveyor, technically) Distances are always given as the horizontal distance. Surveying doesn"t use slope distances (ie. slope of a hill) Metric system is used in almost rest of the world. Sub units are 1/10ths and 1/100ths of a foot. Accuracy: absolute relationship between measured value and true value. Distance measuring using tape can include errors such as: Resolved by comparing length of tape to a standard. Standards are monuments w/ a known distance between them (precisel.
