I have published on such topics as boundary resolution, Texas Land Surveying Practices Act and rules of the Texas Board of Professional Land Surveying. I have personally made over 10,000 surveys on the ground. I have prepared and presented courses for professional development of surveyors and others on numerous occasions.
