Hi this is nice video, I want to ask some question, I have downloaded the las data and when I apply filter for vegetation then I can't see anything, all disappears and when I apply ground filter image is visible. what does this means?

That's probably because no lidar points are classified as vegetation in your downloaded data.

Bisa, diolah saja sampai dapat elevation point clouds, export ke LAS format, sisanya tinggal ngikuti yang di divideo

Hello, this is so amazing. Can I ask you some questions? Where can I download LiDAR imagery and Is there any satellite that has this system?

Satellite based LIDAR currently is under active development by some countries. if you are in U.S , you can download LIDAR data for the whole country from USGS at this website apps.nationalmap.gov/lidar-explorer/#/

Halo, mau tanya kalau misalnya menggunakan nilai canopy ini berarti satuanya nilai tersebut per pixel ya? untuk mengkonversi menjadi per ha/per ukuran pixel tertentu harus di ke polygon ya?

nggak juga, kalau mau pake hektar tinggal ukuran piksel nya berapa dikuadratkan trus dikalikan jumlah piksel pada kelas piksel yang bersangkutan, selesai,
