Object Based Classification using Envi EX

Gambar
Untuk menyambung halaman sebelumnya , maka saya buat short page tentang penggunaan Envi Ex untuk klasifikasi citra satelit (khususnya penutupan lahan) dengan metode Object Based Classification. Dalam halaman pendek ini, berisi tentang :
Proses segmentasi 
Pemilihan attribut / objek yang dijadikan sebagai parameter untuk membantu proses klasifikasi, mulai dari spasial, spektral, tekstur, hingga band rasio (termasuk NDVI).
Ekstraksi objek-objek tertentu
hingga hasil akhirnya
Untuk short pagenya, dapat di download di sini. Semoga bermanfaat. :)

Create Fishnet creates a feature class containing a net of rectangular cells. Creating a fishnet requires three basic pieces of information :
