The .DBF file is still necessary as it supplies the correct colors for elevations. The .XLS file is also still useful for placing things like cities and other "points of interest" on the map if the latitude and longitude are supplied.
That's what I suspected but wasn't sure.

You decide what size you want your map to be (and yes, it should be 64N + 1) and use a zoom factor to acheve that size in Microdem. So if you wanted 449 pixels wide (7 x 64 + 1) you would use a zoom factor of 449/1317 (0.340926347). Once you have the horizontal size defined, you trim the top and or bottom to a 64N + 1 vertical by adjusting the latitudes at the top and bottom with the "keyboard corners".
Your help here tells me that I didn't ask the question right.
How do I decide on what I want the cell count to be? What's average for a map? What's the max for a map?
I'm trying to create a new Southeast USA map. My plan is to try and create a scenario about the birth of Georgia railroading but I would need to include some Alabama cities as well as some in Tennessee, South & North Carolina, and possibly a couple of Florida cities.
I looked at the default Southeast USA map but didn't like it as much as what I hope a Microdem map would be like.
I understand that the max pixel size for a map is 1024 but pixels and cells are two different things, right? How many pixels in a cell?
Does that make sense?
