The Map Radius value sets how large an area around thecenter point to download. Select a value large enoughto cover any plausible flight from that site. Be awarethat loading a large area with a high maximum zoomlevel can attempt to download a lot of data. Loadinghybrid maps with a 10km radius at a minimum zoom of -2and a maximum zoom of 2 consumes about 120MB ofspace. Terrain and road maps consume about 1/10 asmuch space as satellite or hybrid maps.

ALTERNATIVE MAPS: the 10-layer -worldmap-10 (10.7GB) can be downloaded to /library/www/html/modules. Its map data is not as comprehensive as IIAB's 2018 or 2019 maps, and it lacks satellite photos, but it does cover the bases well with basic global maps. One Catch: this download can take hours, as it includes a huge number of small files. 1e1e36bf2d
