Add Survey Term to Dictionary in Your Language

Land Surveyor's Dictionary is an ongoing community project to crowdsource surveying definitions and terms with examples for the next generation land surveyor to learn from. If you are a Land Surveyor, add a term to the Almanac with its definition and examples. Help improve the collective knowledge of the community by improving upon terms added by other surveyors by commenting with your examples and applications in your local surveying environment.
