INTRODUCTORY
04-8.30 3020.
The branch of the Government now known as the Coast and Geodetic Survey
was authorized by act of Congress in 1807, under the administration of President
Thomas Jefferson. From then until the seventies the work of the bureau was
confined almost wholly to surveys of the coasts of the United States necessary to
produce nautical charts. To fix the geographic positions for these charts it was
necessary to establish points of control, and, incident to this, geodetic surveys
were made of the east and west coasts of continental United States. These
included base measurements, triangulation, astronomic observations, leveling,
magnetic observations, etc.
In 1871 the duties of the bureau were broadened to include the making of
* geodetic surveys of the interior of the country which should serve both to con-
✨nect the triangulation on which the coast charts of the Atlantic and Pacific
coasts were based, as well as to establish a geodetic control for mapping and sur-
veying projects in the interior of the country, and in 1878 the name of the then
Coast Survey was changed to Coast and Geodetic Survey.
21-4
In the interval between 1871 and the present time this work has extended in
some of its branches to every State in the Union. While these surveys serve
as the framework for large mapping and surveying projects throughout the
country as well as to determine State and national boundaries, there is no reason
why the data resulting from them, when the points are within available distance,
should not be used for local projects. Indeed, economy of effort in making
local surveys will follow if advantage is taken of previously established standard
points of control because they are basic, and where local surveys intervene between
these standard controls there is a check on the accuracy of the local work.
In mapping a small area of the earth's surface a high degree of accuracy is
not generally attempted in establishing the geographic position of the initial
point. The result is that were it attempted to join several such small maps
together into a homogeneous whole it would be found that there was a certain
degree of inaccuracy which would result in overlaps, gaps, and offsets. This is
a problem that is often met where independent small projects are undertaken
to be joined later into a continuous map. The reasons are that the areas covered
are small and are not coordinated to a scheme of triangulation embracing the
whole country. Similar difficulties follow where small leveling projects are
based on independent and arbitrary data. In addition to the gaps and over-
laps that develop when areas independently mapped, each based on local and
generally arbitrarily selected controls, are joined together, there is a more serious
outcome in that positions must be recomputed from time to time as adjustments
are made and different arbitrary standards are adopted until finally a proper
standard is developed.
The purpose of this booklet is to make available to those engaged in local
surveying projects and others the results of the standard data established by the
Coast and Geodetic Survey, so that there will be an economy of effort in carrying
on local surveys and saving of expense in their recomputation at later dates.
For the reason that the systems of triangulation and leveling by the Coast and
Geodetic Survey extend over wide areas, the publications containing these data
(1)
ご
​2
are not confined to any one State in the Union, but generally contain results for
many States. To get this information in compact form, this booklet has been
prepared. It contains a digest of the work of the bureau in the State of Texas.
In it are shown the places where observations have been made, and, by tabula-
tion, the publication of the bureau containing the results. It is not the purpose
to present here an exhaustive citation of all the uses to which these data can be
put. Their uses are obvious to the engineering profession and therefore the main
purpose of this summary is to make known their existence and how and where
they are available.
TRIANGULATION
The advantages of determining the positions of even farm and ranch boundary
monuments by triangulation are not, it is believed, fully appreciated.
However,
they are obvious when it is considered that the exact positions of such monuments
can be redetermined by triangulation though the monuments be absolutely
destroyed. This is not necessarily true of boundary monuments that depend for
their redetermination on the continued existence of the stones, trees, stumps, etc.,
that mark them. While the initial cost in most instances, where standard data
are within available distance, of basing even farm and ranch surveys on points
established by triangulation connected with standard controls would possibly be
greater than to base them on natural objects determined only by compass bear-
ings, the assertion is ventured with confidence that the ultimate cost would be
much less if we take into consideration the necessity for resurveys from time to
time and the uncertainty resulting from inability to relocate lost corners with
consequent litigation costs, etc. Triangulation stations of the United States
Coast and Geodetic Survey on the coast and in the interior of the country are used
more and more in controlling maps and surveys and also as monuments in private
property surveys. The increased use of triangulation stations for this purpose is
urged upon engineers and surveyors in work involving the location and perpetua-
tion of private property lines or boundaries.
ELEVATIONS ABOVE MEAN SEA LEVEL (FIRST-ORDER LEVELS)
With the increased demands for accurate topographic maps of the country, the
wonderful extension of our good-roads movement, the extension of the railroads,
and the development of river, irrigation, canal, and drainage projects, the net of
first-order leveling that has been partly extended over the country by this bureau
affords bases for local projects that it is feared are not fully known and taken
advantage of by those interested.
There are in most States of the Union lines of first-order levels that are déter-
mined with the highest degree of precision. These are all based on the same
datum plane (mean sea level), and where they are within available distance to use
as the standard for local leveling projects enable the local surveyor to base his
elevations on a standard datum and afford an invaluable check on the local work
if it intervenes between two or more of these standard leveling bench marks.
VARIATION OF COMPASS
All civil engineers are familiar with the use of the surveyor's compass, but many
are not aware of the fact that this bureau has made a magnetic survey of the United
States which includes the determination of the magnetic declination (variation of
the compass) at nearly every county seat in the country. The true meridian has
been marked at many of these stations, and at all of them the true bearings of
several prominent objects from the station have been determined and recorded..
All users of the surveyor's compass should determine the compass correction at
•
3
least once a year at one of these stations.
To reestablish old boundary lines run
originally by compass, of which the boundary marks have been lost, it is necessary
to know the change in the magnetic declination between the date of the original
survey and the resurvey. As a result of its investigation this bureau is prepared
to supply information on this subject from the date of the earliest available obser-
vations to the present time for any locality in the United States.
DIGEST OF PUBLICATIONS
The data resulting from the geodetic surveys by this bureau in the State of
Texas are contained in numerous publications that have been issued by this
bureau. To enable an intelligent selection of a publication containing data of
local interest, the counties of the State of Texas are listed in alphabetical order
and by a tabular arrangement are shown the publications containing the trian-
gulation and leveling data for the State of Texas and the pages in the publications
where the data will be found.
In the tabulation that follows the titles of the publications are at the tops of the
columns. There is one publication, Special Publication No. 77, that contains all
of the published elevations above sea level (in feet and meters) of stations in the
State of Texas. This publication also contains the descriptions of the bench
marks. Special Publications Nos. 11, 17, 54, 78, and 88 contain the positions and
descriptions of all of the triangulation executed by the Coast and Geodetic Survey
in the State of Texas.
For example, if an engineer is interested in the description of the station at
Seguin in Guadalupe County he will turn to Guadalupe County in the alphabetical
arrangement of the counties and the tabulation shows that the description of this
station is shown on page 36 of Special Publication No. 77.
[Magnetic observations have been made at the places indicated below by the asterisk. For fuller details
see note, p. 25.]

NOTE.-The Coast and Geodetic Survey is now preparing to publish its entire collection of information
in regard to the magnetic declination in Texas. The publication will contain the results of all observations,
tables showing the secular change of the magnetic declination, descriptions of the stations occupied, and
an isogonic chart of the State. There are also available in this office the results of observations of magnetic
dip and horizontal intensity at the places indicated by an asterisk, together with corresponding values for
1925, which are to be published in Magnetic Tables and Magnetic Charts for 1925, now in preparation;
also computed values of vertical intensity for 1925.

The foregoing applies to geodetic publications issued by the Coast and Geodetic
Survey. Necessarily, in making geodetic surveys and extending this specialized
branch of engineering the field engineers of the bureau encounter and solve many
problems that are common to surveyors throughout the country. The solution
of such problems has no place in this paper. Many of them are contained in
publications issued by the bureau. The matter is mentioned herein to indicate
the desire of the bureau to be of any possible assistance to the engineering profes-
sion along its specialized lines of activity, and where such problems are brought
to the attention of the bureau all possible assistance will be afforded. Such
inquiries are welcomed, as it is the desire of the bureau to be of the greatest
possible use to the engineering profession, especially those engaged in surveying
and allied branches.
It is the purpose eventually to prepare one digest of the geodetic publications of
this bureau for each State in the Union. Including this one, digests to date have
been made and are available for distribution for the following States: Alabama,
Arkansas, Colorado, Florida, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky,
Maine, Massachusetts, Minnesota, Missouri, Montana, Nebraska, Nevada, North
Dakota, Ohio, Oregon, Rhode Island, South Dakota, Texas, Utah, West Virginia,
and Wyoming. Inquiries regarding any of the matters presented above should
be addressed to the Director of the United States Coast and Geodetic Survey,
Washington, D. C.
