  • Land Surveying in Alabama J. M. Faircloth
    LAND SURVEYING IN ALABAMA J. M. FAIRCLOTH PREFACE There are numerous treatises on land surveying available to the engineer or surveyor today. The legal, theoretical, and practical aspects of general land surveying are all easily available in great detail.* However, there is no writing known to the author which deals specifically with surveying in Alabama or which touches in any appreciable degree upon the problems encountered in Alabama. This manual is not intended to cover the general type of material easily available in the usual surveying text, the manual of the U.S. Land Office or the many other references on surveying; but rather is intended to supplement these writings with information specific to Alabama. The author recognizes a growing need in Alabama for some source of information for the young land surveyor. Few colleges continue to include courses in land surveying in their required curricula, and few references are made to land surveying in the engineering courses on surveying. The increasing values of real property creates a growing public demand for competent land surveyors. The engineering graduate has little training or background for land surveying and has no avenue available for obtaining this information other than through practical experience. One of the purposes of this manual is to provide some of this information and to present some of the problems to be encountered in Alabama. The Board of Licensure for Professional Engineers and Land Surveyors in Alabama is faced with the problem of a large public demand for land surveyors that cannot be filled on the one hand, and the maintenance of high professional standards with adequate means for training land surveyors on the other.

  • 6.- Methods for Latitude and Longitude Measurement
    Chapter 6 Copyright © 1997-2004 Henning Umland All Rights Reserved Methods for Latitude and Longitude Measurement Latitude by Polaris The observed altitude of a star being vertically above the geographic north pole would be numerically equal to the latitude of the observer ( Fig. 6-1 ). This is nearly the case with the pole star (Polaris). However, since there is a measurable angular distance between Polaris and the polar axis of the earth (presently ca. 1°), the altitude of Polaris is a function of the local hour angle. The altitude of Polaris is also affected by nutation. To obtain the accurate latitude, several corrections have to be applied: = − ° + + + Lat Ho 1 a0 a1 a2 The corrections a0, a1, and a2 depend on LHA Aries , the observer's estimated latitude, and the number of the month. They are given in the Polaris Tables of the Nautical Almanac [12]. To extract the data, the observer has to know his approximate position and the approximate time. When using a computer almanac instead of the N. A., we can calculate Lat with the following simple procedure. Lat E is our estimated latitude, Dec is the declination of Polaris, and t is the meridian angle of Polaris (calculated from GHA and our estimated longitude). Hc is the computed altitude, Ho is the observed altitude (see chapter 4). = ( ⋅ + ⋅ ⋅ ) Hc arcsin sin Lat E sin Dec cos Lat E cos Dec cos t ∆ H = Ho − Hc Adding the altitude difference, ∆H, to the estimated latitude, we obtain the improved latitude: ≈ + ∆ Lat Lat E H The error of Lat is smaller than 0.1' when Lat E is smaller than 70° and when the error of Lat E is smaller than 2°, provided the exact longitude is known.

  • Straight Streets in a Curvaceous Crescent
    Article Journal of Planning History 1-16 ª 2018 The Author(s) Straight Streets in a Curvaceous Article reuse guidelines: sagepub.com/journals-permissions Crescent: Colonial Urban DOI: 10.1177/1538513218800478 journals.sagepub.com/home/jph Planning and Its Impact on Modern New Orleans Richard Campanella1 Abstract New Orleans is justly famous for its vast inventory of historical architecture, representing scores of stylistic influences dating to the French and Spanish colonial eras. Less appreciated is the fact that the Crescent City also retains nearly original colonial urban designs. Two downtown neighborhoods, the French Quarter and Central Business District, are entirely undergirded by colonial-era planning, and dozens of other neighborhoods followed suit even after Americanization. New Orleanians who reside in these areas negotiate these colonial planning decisions in nearly every movement they make, and they reside in a state with as many colonial-era land surveying systems as can be found throughout the United States. This article explains how those patterns fell in place. Keywords New Orleans, Louisiana, cadastral systems, colonial planning, planning eras/approaches, French Quarter, surveying systems, French long lots Origins Men under the command of Jean-Baptiste Le Moyne, Sieur de Bienville began clearing vegetation for La Nouvelle-Orle´ans in the early spring of 1718. Their proximate motivation was to establish a counter-office for the Company of the West, to which a monopoly charter had been granted by Philippe, the Duc d’Orle´ans and Regent of France, for the creation of an enslaved tobacco plantation economy. The ultimate motivation for the foundation of New Orleans was to create a French bulwark near the mouth of the Mississippi River to control access to France’s 1682 claim of the vast interior valley, while preventing the Spanish and English from doing the same.1 Where exactly to locate New Orleans had vexed French colonials.

Exercises in Archaeoastronomy - 2 - The passage mound of Newgrange Amelia Carolina Sparavigna (Department of Applied Science and Technology, Politecnico di Torino) Published in enviro.philica.com Abstract Here it is given the second article of a series proposing exercises in archaeoastronomy. The reader can find exercises about the apparent motion of the sun, and its azimuth and altitude given in the horizontal coordinate system. As case study, we investigate the orientation of the prehistoric passage mound of Newgrange. In the previous article [1], we have introduced a series of exercises in archaeoastronomy. Let us start the series by studying the sun and its horizontal coordinates. After exercises on azimuth and altitude of the sun, we consider some prehistoric monuments. In particular we propose exercises on the passage mound of Newgrange, as a case study.
