Land Surveying: Data Collection, Processing, and Presentation, Lecture notes of Geodesy and Cartography
An overview of the general stages of land surveying, including field orientation, data collection, processing, and presentation. It covers various methods of terrestrial mapping, such as triangulation and trigonometric leveling, as well as extraterrestrial mapping using photogrammetry. The document also discusses the calculation of Cartesian and geographic coordinates and the presentation of data through maps, graphs, and sketches. References to relevant literature are included.

Pemetaan Terestris
Penggunaan Total Station
Total Station merupakan alat pengukur jarak dan arah (sudu horisontal dan sudut vertikal) otomatis. Alat total station dilengkapi dengan chip memori, sehingga da pengukuran sudut dan jarak dapat disimpan untuk kemudian didownload dan diolah secara computerize
Pemetaan Ekstraterestris
Penginderaan Jauh
Data yang dihasilkan dari teknik pengindaraan jauh berupa beberapa bentuk citra yang selanjutnya diproses dan diinterpretasikan sehingga diperoleh informasi yang dapat digunakan untuk aplikasi dibidang pertanian, kehutanan, geografi, geologi, perencanaan, arkeologi dan bidang-bidang lain.
Pemetaan Ekstraterestris
Global Positioning System
(GPS)
Konsep dasar pada penentuan posisi dengan GPS adalah reseksi (pengikatan kebelakang) dengan jarak, yaitu dengan pengukuran jarak secara simultan ke beberapa satelit GPS yang koordinatnya telah diketahui
Penyajian Data (penggambaran) :
Hasilnya berupa :
* Peta
* Grafik
* Sket
