tileedit.exe is a visual inspection utility for planetary texture tiles.
It contains some rudimentary capabilities for editing elevation data.

To run tileedit.exe you must install the MATLAB R2015a runtime package
(MCR_R2015a_win64_installer.exe), which can be downloaded from

http://uk.mathworks.com/products/compiler/mcr/

Be sure to download the Windows 64-bit runtime for R2015a (8.5),
*** NOT the R2015aSP1 ***.
