TUGAS AKHIR SIDS MEMBUAT PROJECTS WEBGL GLOBE MEMBUAT SEBUAH TOLKING DATA BISA TAU PENGGUNA YANG MEMAKAI MOBILE
UNIVERSITAS BHAYANGKARA SURABAYA
projects
yang saya buat untuk membuat tolking data bisa tau pengguna yang
memakai mobile dari pengguna laki - laki dan perempuan dalam menemukan
titik koordinat yang paling banyak yang menggunakan pengguna mobile
tersebut yang akan ditampilkan di webgl globe berikut cara proses
pembuatannya. jadi saya kebagian untuk pengolahan data dan programnya
- bahan yang dibutuhakan dalam projects tersebut seperti berikut :
1. install anaconda
2. siapkan data yaitu (toolking data pengguna mobile)
3. access webgl globe
berikut langkah - langkah pembuatannya :
1. pertama kita download data nya berikut datanya
jadi datanya ada 2 file yang dengan isi berbeda, file pertama bernama file events seperti berikut.
jadi data diatas mencakup event_id, device_id, timestime, langitude,
latitude. jadi yang event_id sama timestamp tidak saya butuh kan jadi
tinggal dihapus saja. jadi total data yang diatas mencapai 116510 jadi
kita potong 3000 data saja
2. data yang kedua bernama gender yang mencakup device_id, gender. seperti berikut datannya
jadi datanya file gender saya potong 3000 data menyesuaikan data events.
3.
dari kedua data yang sudah saya sebutkan dari kedua data punya
device_id jadi datanya saya gabung menjadi satu, setelah digabungkan ada
data yang sama di merge nanti jadi magnitude nya, selanjutnya data
gender difilter mana yang perempuan mana yang laki-laki. berikut hasil
datannya yang sudah digabungkan. untuk fungsi magnitude saya tambahkan
sendiri kedalam data nya agar mengetahui paling banyak pengguna mobile
tiap khusus perempuan dan laki - laki
4. jadi kalo sudah selesai kita compress datannya menjadi file json. coba akses untuk convert secara online berikut link nya https://codebeautify.org/csv-to-json-converter#
5. seperti berikut hasil data nya sudah convert ke json nya
6. lalu kita buat programnnya html nya dan GET json berikut programnya.

};
7. lalu letakan datanya di File C:Users/RICKYEKA, seperti berikut contoh nya.
8. langkah selanjutnya buka anaconda prompt, lakukan perintah ini : python -m http.server
9. lalu buka browser lakukan perintah ini : http://localhost:8000/webgl-globe-mastera/globe/
