Recent website updates include:

• Material added to XI. Mapping
• Added Chapter G. Theodolite and Total Station to XV. Instrument Errors and Corrections
• Rearranged and added material in VII. Total Station Instruments.

In the pipeline:

• Adding more TSI operations to VII. Total Station Instruments
• Adding a data acquisition chapter to XI Mapping (or possibly as a separate topic).
• Am toying with the idea of a Formal Coordinate Systems topic

Been trying to make good use of pandemic isolation.
