jp2 elevation file not opening in Global Mapper v.17

danielek Global Mapper User

In GM 16 I was using an elevation file of Mars in jp2 format derived from a GeoTIFF file (Equirectangular/Mars Sphere). The GeoTIFF file survived version 17, but the jp2 file returns the following error:

Unable to load overlay VallesMarineris.hrsc_100m.jp2
ECW error SetView() Error - View size is limited to 4000x4000 or 64 high in progressive mode
ECWOverlay.cpp - 4247
Version: v17.0.2 (64-bit)
Build Time: Oct 19 2015 19:57:11

Image length and width are 36000x13200.

Will it be fixed in a forthcoming release?

    I recommend getting the latest release of Global Mapper (17.0.5) to see if the problem has already been fixed. If the problem persists in the latest release, then your best bet is to send an e-mail describing your workflow and the results (error message, etc.), with a copy of your data, to Blue Marble Geographics support ( This will ensure that the support team sees the problem and can provide a timely response. Thank you.
