calculate NDVI from ortophoto
« on: September 29, 2016, 04:40:46 PM »
Hello,
I can create an ortophoto using Photoscan.

Is it possible to get NDVI map from that ortophoto using Photoscan? If so, how can I?

thanks

Hello mfran2002,

After generating the orthomosaic you can open Raster Calculator window whilst in the Ortho view mode and input the index calculation formula and it's color representation to the dialog.

Hi Alexey and thank you again for your help!

excuse me for my limitations but I can't find this utility. I use Photoscan version 1.2.4

May you please guide me to that function? If possible also with an helpful  screenshot...

Hello mfran2002,

Double-click on the Orthomosaic label in the Workspace pane to open the Ortho view mode, then on the new toolbar click on the Raster Calculator button ("palette" icon).
