Hi there!I've created a mesh file from 3Arcsec hgt files.Checking the bgl file with tmfviewer,there are a lot of holes..I've changed interpolationPasses from 10 to 20 but no change..How to solve it?Thanks for your help.enel

Hi Enel,If the holes are small, you can use FSDEM, downloadable from the AVSIM library (see a previous post in this forum). If the holes are larger, you can also use Blackart, see www.terrainmap.com/rm38.htmlRegardsAlain

Hi Alain, thank you for your response.FSDEM:I use "LOAD MULTIPLE HGT FILES" to load 10 files...it's hang due to low memory :-(I've 169 hgt files to create my mesh file...Bye
