Clicking the button with the document icon will take you to a page with information about all the maps. I'll be enhancing this in the coming days, so it takes you to a separate page of detailed information for the map you're currently viewing.
Took a week, but this feature is now fully implemented (phew). Click the little document and you will get lots of info about the map plus links to the full metadata and more. For example:
https://online.boydsmaps.com/njgin2012-map-info/
BTW, the 1930, 1970 and 1977 imagery comes from NJDEP, which is different from the other aerials. Check out the "Use Constraints" section of the map info.... evidently we have no right to even look at these
https://online.boydsmaps.com/njgin1930-map-info/ "Digital data received from the NJDEP are to be used solely for internal purposes in the conduct of daily affairs."
Now there are even more buttons to push!
Pine tree - center map on Chatsworth
Bullseye - go to center of currently selected map
Document - show map information
Down Arrow - download the currently selected map
Question Mark - help files
...But you don't need to memorize these, just pass your mouse over the buttons and a description will appear.
I have also expanded the coverage area of the maps, in preparation for adding a LOT more imagery of Pennsylvania and New York. This won't happen unitl after I make a major change to the map menu with separate groups that you can expand/collapse. The bullseye button will help you navigate between maps of completely different areas. I think you'll find it handy now when you want to view the 1970 and 1977 aerials. No more blank screens - just click the bullseye!
But it may also take you pretty far away from the area you're currently viewing. The openstreetmap topo's (at the bottom of the map menu) cover the whole world, so I have set the bullseye to just go to the center of my Mid-Atlantic coverage area... for example:
https://online.boydsmaps.com/#15/40.7553/-75.2685/hikebike-x If you suddenly feel lost, just click the pine tree and you'll return to Chatsworth.
The download button takes you to the boydsmaps.com web page for the MOBAC version of the map (if one is available).
Have made a bunch of other changes "under the hood" too... you can zoom in farther on more of the maps, and the quality should be slightly better. I also found a big error in how the map was configured that may have been slowing things down.
The help files need to be updated to include these changes, that should happen soon.
Have been struggling to understand how to properly center the little icons on the new map buttons - my Macs look like the screenshot above, but the icons don't line up as well on Firefox or Chrome on my Windows computer, and they're totally wrong on my iPad. Hopefully this will get sorted out soon. But at least I figured out how to make the pine tree green.
