Fundamentals of Corner Restoration

Course Summary:

The Bureau of Land Management Cadastral Survey Training Program was established in 1970. At that time there were extremely few publications available on the subject of Cadastral Surveying. For various reasons none were entirely suitable for use as teaching materials.

In order to provide suitable materials for the training job at hand, a very considerable portion of the effort expended toward presentation of the training program involved development of training materials. This book was one such development.

Any teaching material used for training must present accurate information and correct procedures. Any instructional material for use in training cadastral surveyors must not only be correct but it cannot conflict with the instructions given in the Manual of Surveying Instructions. Because the BLM Manual of Surveying Instructions was undergoing complete revision in 1970, during development of this book, it became clear that a text consisting of instructions would unnecessarily paraphrase the Manual to be revised.

Under the conditions at that time the logical method of development of the needed materials was to present actual approved surveys. It would be necessary to provide greater detail than is usually available and to describe how the particular solution was reached. Because the material was factual and had been approved by the Washington Office, the system was adopted.

This compilation of Public Lands Surveys is intended for self-study as well as for use in classroom instruction. It is intended that anyone versed in survey technology who uses this book and the Manual of Surveying Instructions could master the fundamentals of Public Lands Surveying, particularly the resurvey of those lands (as opposed to the original surveys.)

In addition to its use as instructional materials, it is expected that this casebook can be used as a reference work for the practicing surveyor. A number of frequently occurring problems are not discussed in any other publication.
