From the IMC documentation:
",,, repurposing of Raster Nautical Charts required a new key as a positive enabler DVOR standing for Disable Vector Over Raster."
Make sense to add DVOR=TRUE to description string when we select raster output and Raster Chart type.

Hello, Matt.
I will support Volccc. Do you plan to further develop the RM project? Is it possible to include in the next update support for raster types from the IMC (Raster navigation map) using the dvor key? Satellite, Shaded Relief? www.tacklefever.de/index.php?topic=6169.0

If you can tell me more about this option, where to set it, and what it does, then I will look into it.

Starting from atlas 12 Lowrance defines 4 types of raster maps:
www.tacklefever.de/index.php?topic=6168.0

And we can have 3 raster layers in one map:
1. Shaded relief - visible if we select Shaded Relief in device.
2. Satellite imagery - visible as Photo Overlay
3. Raster nautical chart - visible if we select Raster charts

I've asked about 3 - it works only with additional key in atlas description string:
www.tacklefever.de/index.php?topic=6169.0
So if we select raster output and raster chart type of output, we need description string in the IMC project to looks like
"M=My awesome map|DVOR=TRUE"

So DVOR=True should always be set when the output type is RNC?
And is a project description string always required in this case, or can the description string consist only of "DVOR=TRUE", with the preceding "M=ProjectName" ?
The simplest way to implement this would be to add a user-selectable field in the export window, but if it is always (and only) required for RNC, then it would be less confusing to simply add it in this case.

Always and only required for RNC, for atlas 12 and higher. Can be the only key in description string.

OK, thanks. We can include this in a maintenance release that was coming up shortly anyway.

Always and only required if you want it to display in it's own layer in lieu of vector.

Otherwise, it aliases to the same thing as Shaded Relief.

Maybe make sense, for simplifying usage, rename raster type selection in combobox to:

Shaded relief
Photo overlay (was satellite)
Raster chart

And remove ability to select topo.

Hello, Matt.
I have RM 2.1.52.0 installed. I can't get a different type of Satellite and Shaded relief raster at the output. If I do it directly in the IMC everything works out and I can switch the raster type in my HD Live. В чем может быть проблема?

Hi Ershal, is this changed behaviour since 2.1.50? I am wondering if the DVOR tag is having an influence here, as that is the only thing that should have changed with respect to raster export. I will look into it.
