Pyramid Layers
• Ukuran image yg besar: lebih cepat ter-

display
• Menjadi tambahan layer utk *.img file
• External ke *.img file
 Tambahan file (.rrd)
• Internal ke *.img file
 Ukuran file meningkat sekitar 1/3

Image Drape dan VirtualGIS
• Image Drape membuat scene 3D secara statis

perspective
Untuk banyak aplikasi hal ini dirasakan cukup berguna

• VirtualGIS menampilkan real time flight

menggunakan citra, data vektor dan data anotasi
