Starts Initializing GPS Reception
Before you can start using the Garmin 60CSx
GPSmap, you have to wait until it says "The GPS to
intialize" on the GPS screen. This process means
that the device has allowed the GPS to receive and
store satellite data and then we can start using the
satellites for navigation. This initial process occurs
automatically and only takes a few minutes.
GPS units require satellites to start operating. For
that, bring the GPS into the open to find a satellite
signal. When the Unit is searching, the GPS display
will say "Locating Satellites".

History, Function & How GPS Works
Total Station (TS)
Total Station (TS) is a tool used in mapping and building
construction.
Total Station is a tool for measuring distances and angles
(horizontal and vertical angles) automatically. TS is equipped with a
memory chip, so angle and distance measurement data can be
stored for later download and computational processing. The total
station is a kind of theodolite that is integrated with an electronic
distance meter (EDM) component to read the distance and slope
from the instrument to a certain point.

54. Total Station (TS) & LiDAR
History, Function & How GPS Works
LiDAR
Light Distance And Ranging or what we usually know
as LiDAR is an object detection method that uses the
principle of laser light reflection to measure the distance
of objects on the earth's surface. This technology was
first used in the 1960s for aviation purposes, but has
only recently been popular for mapping systems since
the 1980s until now.

Editor's Notes
Pemasangan BateraiSebelum memulai silahkan pasang baterai terlebih dahulu. GPS Garmin 76CSx beroperasi dengan memakai dua baterai AA yang terpasang di belakang body. Begini cara memasang baterai pada GPS 76CSx:
Buka penutup baterai dengan cara memutar kunci penutup baterai secara berlawanan arah pada putaran jarum jam, lalu tarik penutup baterai hingga bisa dibuka.
Masukan baterai seperti biasa kemudian tutup kembali kunci penutup baterai seperti semula.
Jika sobat tidak memakai GPS tersebut selama jangka waktu lewat dari sebulan, lebih baik lepaskan saja baterainya. Jangan kuatir data yang tersimpan tidak akan bisa hilang atau terhapus.
Pemasangan MicroSDMicroSD berguna untuk menyimpan file, foto dan peta digital yang terketak di bawah baterai.Untuk memasang atau melepas microSD, silahkan buka penutup baterainya terlebih dahulu. Caranya sama seperti langkah di atas (Pemasangan Baterai).Selanjutnya cari microSD di dalam slot bawah baterai dan kemudian tekan perlahan tepi atas micro SD sampai bunyi "KLIK". Cara melepasnya pun sama ketika melakukan pemasangan microSD, yaitu tekan perlahan hingga bunyi "KLIK" dan biarkan sampai kartu terlepas.
Menampilkan Halaman UtamaGPSmap 76CSx mampu menampilkan seluruh informasi yang dibutuhkan untuk navigasi dihalaman utama (layar tampilan). Terdapat 5 halaman utama yang bisa ditemukan antara lain Satelit, Trip Computer, Peta, Compas, Altimeter dan Main Menu. Tekan tombol Page Key untuk melihat halaman yang di inginkan.
Memulai Inisialisasi Penerimaan GPSSebelum bisa memulai menggunakan GPSmap garmin 76CSx, sobat harus menunggu terlebih dahulu hingga ada tulisan "The GPS to intialize" pada layar GPS. Proses tersebut berarti perangkat telah mengijinkan GPS 76CSx untuk menerima dan menyimpan data satelit dan kemudian kita bisa memulai menggunakan satelit untuk navigasi. Proses awal ini terjadi secara otomatis dan hanya memerlukan waktu beberapa menit saja.
Unit GPS memerlukan satelit untuk bisa memulai beroperasi. Untuk itu bawalah GPS ketempat terbuka hingga menemukan sinyal satelit. Ketika Unit sedang mencari, di layar GPS akan tertulis "Locating Satellites".
Menentukan Penandaan (Waypoint)Dengan Waypoint sobat bisa menyimpan setiap titik pada Map Page di memori yang nantinya digunakan sebagai arah untuk navigasi. Kemudian sobat juga bisa menciptakan sebuah waypoint di lokasi saat ini, nama waypoint dan kemudian menyimpannya digunakan dalam sebuah route. Begini cara menentukan waypoint:
Tekan tombol ENTER sampai halaman mark waypoint muncul.
Tekan ENTER pada waypoint name dan simbol untuk mengganti waypoint dan waypoint symbol sesuai dengan keingingan sobat.
Setelah semua selesai pilih "OK" kemudian tekan ENTER.
Memasukan DataSobat bisa menggunakan tombol ROCKER dan ENTER untuk memasukan atau mengubah data. Untuk membidik "The Field" yang ingin diubah, silahkan tekan tombol ROCKER ke kiri, kanan, atas dan bawah. Untuk memilih "The Field" tekan tombol ENTER, kemudian gunakan tombol ROCKER untuk memilah suatu pilihan dari sebuah Menu dan kemudian tekan tombol ENTER.Disini sobat bisa memasukan kata dan nomer dengan bantuan ROCKER dan on-screen keyboard. Untuk memasukan data, gunakan ROCKER untuk membidik sebuah kata nama dan nomer. Untuk memilih kata nama dan nomer yang sudah dibidik tekan saja ENTER. Teruskan pemilihan kata dengan ROCKER dan ENTER. Jika sudah selesai bidik "OK" dan tekan tombol ENTER.
Menciptakan dan Menampilkan TrackTrack dapat diterjemahkan dalam bentuk sebuah jejak kaki. Jejak kaki ini ditampilkan dengan teliti kearah manapun ketika sobat bergerak. Track ini tampak seperti titk-titik pada layar "Map Page". GPS Garmin 60CSx/76CSx akan secara otomatis mencatat track dari perpindahan atau pergerakan sobat dan ditampilkan dalam bentuk garis bertitik atau yang disebut dengan "a track log". Untuk membuat track adalah dengan cara sebagai BERIKUT:
Tekan timbil menu dua kali kemudian pilih Track.
Pilih clear (Jika precentage of memory in use belum 0%), lalu tekan ENTER. Kemudian akan muncuk konfirmasi dan pilih OK.
Ketika track mencapai 0%, maka track baru siap digunakan.
Untuk membuat track baru, sobat dapat memilih ON kemudian tekan ENTER.
Jika track selesai, simpan track dengan cara memilih menu SAVE kemudian tekan ENTER.
Cara Mencari TempatSobat bisa menggunakan "Find Page" agar dapat mencari Waypoints, Geocache poinrs dan cities. Jika sobat sudah menyimpan data tersebut, maka sobat bisa mencarinya kembali.Cara menemukan Waypoint:
Tekan FIND maka Find page akan tampil, Kemudian bidik Waypoint lalu tekan ENTER. Gunakan ROCKER untuk menampilkan daftar nama dan bidik Waypoints yang ingin sobat dapatkan. Pilih Waypoint dengan menekan ENTER, maka layar informasi Waypoint akan tampil.
Untuk membidik map gunakan ROCKER dan jika sobat ingin melihat Waypoint di peta tekan ENTER. Kemudian pilih "Go to" untuk memulai navigasi.
Cara Menciptakan RuteRute adalah arah sebuah garis dari satu titik ke titik lainnya, atau dari satu titik ke beberapa titik lainnya. Sobat bisa membuat sebuah garis rute sederhana, yaitu dengan mendapatkan sebuah Waypoints dan mengaktifkan "go to". Tidak hanya demikian, disini sobat juga bisa menciptakan sebuah rute yang lebih kompleks (melibatkan banyak titik) dengan "Routes Page". Cara membuat rute adalah sebagai berikut:
Tekan MENU dua kali, kemudian pilih "Routes".
Pilih New, lalu pilih Next Point.
Gunakan Menu Find untuk memilih rute Waypoints dari salah satu Find groups.
Pilih Select next pount untuk menambahkan waypoint ke dalam rute. Tentukan waypoint yang akan digunakan (Recent Finds / Waypoints / Cities / Geochache / marine). Pilih waypoint yang sobat inginkan tersebut dan kemudian ENTER lalu pilih Use, tekan ENTER lagi (Lakukan seperti itu terus sampai seluruh waypoint yang dibutuhkan semuanya ada).
Pilih Navigate, lalu tekan ENTER.
Pilih Follow Road (apabila rute tersebut dibuat mengikuti jalan) atau off road (apabila rute yang dibuat tidak mengikuti jalan).
Cara Menghitung Luas AreaGPSMap Handheld 60CSx/76CSx sangat cocok digunakan sebagai alat pengukur di lapangan. Disini sobat bisa menentukan luas daerah lahan pertanian, pertambangan, pemukiman, pertanahan dan lain sebagainya. Namun secara default fitur menghitung luas belum ada di GPSmap 60CSx/76CSx, maka dari itu kita harus men-setingnya sendiri dengan cara manual. Caranya adalah sebagai berikut:Hidupkan unit GPSmap 60CSx atau 767CSx, tunggu hingga terhubung dengan sinyal satelit. Apabila indikator sinyal satelit sudah muncul dan koordinat sudah ada berarti GPS sudah siap dipakai.
Tekan tombol Menu dua kali, jika muncul halaman menu utama pilih SETUP
Tekan tombol ENTER
Pilih Page Squence lalu ENTER
Muncul tambahan halaman, kemudian tekan tombol ROCKER bawah sampai ada pilihan Add Page kemudian ENTER. Pilih Area Calculation dan akhiri dengan menekan tombol ENTER.
Jika sudah menambahkan halaman, langkah berikutnya adalah memunculkan halaman "Area Calculation" dengan cara menekan tombol PAGE beberapa kali.
Tekan tombol Start di halaman Area Calculation, setelah sobat ENTER tombol Start akan berubah menjadi tombol stop, apabila demikian artinya GPS sudah bisa digunakan untuk menghitung Luas Area.
Memulai PengukuranCobalah sobat berjalan di area yang akan dihitung luasnya, dari titik A (awal) dan kembali ke titik A (akhir). Setelah berjalan mengelilingi area yang diukur, kemudian tekan tombol Stop. Nah nantinya di bawah tombol stop akan muncul hasil perhitungan area tersebut.Pada halaman yang lain akan muncul keterangan dari hasil kalkulasi area yang sobat lakukan tadi, seperti:
Name (tekan tombol ROCKER ke atas sampai ke Field Name untuk mengganti nama yang diinginkan). Kemudian tekan ENTER dan isi nama yang diinginkan.
Informasi Distance (jarak), Area dan Color (warna).
Setelah semua selesai tekan tombol OK untuk menyimpan semua hasil pengukuran.Catatan : GPS Garmin memiliki tingkat akurasi sekitar 5 - 15 meter, sehingga tidak disarankan untuk mengukur luas area. Untuk pengukuran yang lebih akurat sobat bisa menggunakan GPS tipe pemetaan atau GPS Geodetik yang akurasinya bisa mencapai 5mm-10mm.
Total Station (TS) adalah alat yang digunakan dalam pemetaan dan konstruksi bangunan.
Total Station merupakan alat pengukur jarak dan sudut (sudut horisontal dan sudutvertikal) secara otomatis. TS dilengkapi dengan chip memori, sehingga data pengukuransudut dan jarak dapat disimpan untuk kemudian didownload dan diolah secara computasi. Total station merupakan semacam teodolit yang terintegrasi dengan komponen pengukur jarak elektronik (electronic distance meter (EDM)) untuk membaca jarak dan kemiringan dari instrumen ke titik tertentu.
Light Distance And Ranging atau yang biasa kita kenal dengan LiDAR adalah suatu metode pendeteksian objek yang menggunakan prinsip pantulan sinar laser untuk mengukur jarak objek yang ada di permukaan bumi. Teknologi ini pertama kali digunakan pada tahun 1960-an untuk keperluan penerbangan, namun baru populer untuk sistem pemetaan / mapping sejak tahun 1980-an hingga sekarang.
