About Us


Author and Coder: Marcus Sidler,
Registered Land Surveyor in Arizona, California, Nevada, and New Mexico,  CFedS and Vice President of Lemme Engineering Inc. Phoenix Arizona.
Thirty years of surveying and using many different software packages for computing and survey analysis met with frustration and disappointment. 
Most software is very versatile but not user friendly,  so I put together my own set of routines that are visual in nature and CADD is a distant memory.
