Global Mapper Pro

Yellow line grid squares show up on my aerial photo when exporting to SQLITEDB (rmaps)

Yellow grid type squares are appearing on my aerial photos I export to rmaps (sqlitedb) They only show up when zooming in. Why does my aerial photo have those annoying lines and how do I stop it from creating those?

    First, make sure you have the latest version of Global Mapper 17.  I recall that the early releases of Global Mapper 17.2 had a problem where tiles were being created one pixel too small, and that has been fixed.

  • Hi,

    I did upgrade to the latest Global Mapper 17.  I created some rmaps .sqlite files at zoom 16 and they did not have the grid lines, then I tried another map at zoom 16 and they had many grid lines.  That was using the .jpg format tiles.  I am trying it again  with .png tiles to see if it happens there.
