I am currently designing a geospatial product that will be primarily used for large and intermediate scales that cover an entire state of the US or more.
The UTM projection would be ideal because of its conformal properties.
But, I am not crazy about it for the product I am designing because of states that may encompass more than one UTM zone. Of course I could render all of the imagery in one zone or the other, but it seems problematic, especially for possibly combining the products together some day in the future into a national US dataset. My source data is in variety of projections, that I will be reprojecting to a common projection.
So I need to decide on my common server-side projection, and possibly a different projection for my clients (if needed but not desirable). Is Albers Equal Area a good choice?
EDIT: The product shall be in the form of topographic maps in both Large Scale (1:24k) and Intermediate Scales (1:63k).
EDIT: I should like my national projection to minimize distortion when projecting to a client projection, as I will have pre-rendered raster images - not just vector data, so I don't think geographic is best.
EDIT: Here is another way to ask the question (I'll figure the rest out on my own or ask as a second question). For a Large Scale topographic viewer, that could view across multiple UTM zones and multiple State Planes at any time depending on its center, what projection would you recommend serving to the view?
