+
+ Before heading out to a new launch site, you can use
+ this to load satellite images in case you don't have
+ internet connectivity at the site.
+
+ There's a drop-down menu of launch sites we know
+ about; if your favorites aren't there, please let us
+ know the lat/lon and name of the site. The contents of
+ this list are actually downloaded from our server at
+ run-time, so as new sites are sent in, they'll get
+ automatically added to this list. If the launch site
+ isn't in the list, you can manually enter the lat/lon
+ values
+
+ There are four different kinds of maps you can view;
+ you can select which to download by selecting as many
+ as you like from the available types:
+
+ Hybrid::
+ A combination of satellite imagery and road data. This
+ is the default view.
+
+ Satellite::
+ Just the satellite imagery without any annotation.
+
+ Roadmap::
+ Roads, political boundaries and a few geographic
+ features.
+
+ Terrain::
+ Contour intervals and shading that show hills and
+ valleys.
+
+ You can specify the range of zoom levels to download;
+ smaller numbers show more area with less
+ resolution. The default level, 0, shows about
+ 3m/pixel. One zoom level change doubles or halves that
+ number. Larger zoom levels show more detail, smaller
+ zoom levels less.
+
+ The Map Radius value sets how large an area around the
+ center point to download. Select a value large enough
+ to cover any plausible flight from that site. Be aware
+ that loading a large area with a high maximum zoom
+ level can attempt to download a lot of data. Loading
+ hybrid maps with a 10km radius at a minimum zoom of -2
+ and a maximum zoom of 2 consumes about 120MB of
+ space. Terrain and road maps consume about 1/10 as
+ much space as satellite or hybrid maps.
+
+ Clicking the 'Load Map' button will fetch images from
+ Google Maps; note that Google limits how many images
+ you can fetch at once, so if you load more than one
+ launch site, you may get some gray areas in the map
+ which indicate that Google is tired of sending data to
+ you. Try again later.
