<p><span style="font-family: Arial;">I recently downloaded several images from Digital Globe. These include WV2 and WV3 images of my study site, and they are currently in *.til format. I have previously downloaded WV2 imagery of this area and successfully worked with it in ENVI (a previous version). My organization recently upgraded to ENVI 5.3.&nbsp;</span></p> <p><span style="font-family: Arial;">I have two issues: U</span><span style="font-family: Arial;">nfortunately, when I navigate File &gt; Open as &gt; WorldView2 and select the *.til file I receive an error message along the lines of "Can't open, you don't have the NTTF license." I don't know what this means and can't find it on the web :/</span></p> <p><span style="font-family: Arial;">Second:&nbsp;</span><span style="font-family: Arial;">&nbsp;there is no WorldView3 option under "open as" and if I try WV1 or WV2 it simply says "this isn't a WV2 file," which is true... but I'm stuck on how else to open this data.</span></p> <p><span style="font-family: Arial;">Has anyone else had a similar problem opening WV2 in ENVI 5.3? Has anyone successfully opened WV3 data in ENVI 5.3? All feedback is welcome. I realize (and hope) there's a simple solution here and I'm just unaware.&nbsp;</span></p>
