‘m not sure if it varies by monitor type, but my laptop will show approximately 1 degree latitude by 3 degrees longitude at an eye altitude of approximately 130 miles. Maybe that could be included in your notes as a recommended maximum zoom out.

I think that will vary by monitor resolution and also the latitude you’re looking at. For example, go up near the poles and it will change quite a bit. I’m trying to get the Global Mapper developer to add another option to the export, which will automatically turn on/off the grids as you navigate around. If I can do that, then I’ll make the grids smaller.

Also, if the grid is reconfigured in the database to 1×3 to match the display, it might cut down on the processor loading. No need to load points that will not appear on the screen anyway.

Thanks Frank. You’re correct, that there is a lot that can be done with this. What you see now took a minimal amount of effort on my part. Basically, I loaded the source data into MS Access. Exported a text file containing the fields I wanted. Loaded that text file with a beta of Global Mapper 11 (which has a new feature to automatically create the 3×3 degree grid index), and hit export to KMZ. I could also add different icons for the different categories of places, or allow the user to turn on/off different categories.

Nice little project. The obvious way to control the data would be to use network links based on view based refresh to select the grids, and regioning to control the amount of data shown based on proximity. Also, I would suggest a better choice of icons for places. Does the data have population for places? If so, you could size icons based on location.

It would be nice to be able to selectively control parameters such as font size, regioning levels, label colors, icons, etc. And then automatically generate a variation on the network link to show the data. That would take some work though.
