Here? a question for Lambert state plane coordinate system users. Over how big an area can a Lambert state plane coordinate system give usable results? Before you answer, consider the following…Read More

Having admired surveyors and their profession since introductory trig in high school, he has studied and developed Lambert conformal conic projections informally since 2010.
Back in January, 2016, Loyal Olson described a consulting project that required raising a state plane so that ground distances were very close to grid distances and state plane grid azimuths were preserved. The purpose of this post is to share the results of the research that Loyal? post prompted me to do. Let? explore the relationships and mathematics that make it possible to raise a Lambert state plane projection to provide ground distances and grid azimuths over a limited area.Read More
