2. **Map Packs** no longer bundle both data and program in a .zip file. All Map Packs are really now just a collection of 3 .mbtiles files:
1. The main focus of a Map Pack remains Hi-Res Vector Map data from OpenStreetMap, for your selected "continent" — but Lo-Res vector map tiles (1.74GB .mbtiles) and Lo-Res satellite photos (932MB .mbtiles) are also included for the entire planet.

2. Map Packs' OSM vector tile data (originally from 2017) was updated to [September 2019](https://archive.org/details/osm-vector-mbtiles).
2. Every Map Pack's OSM vector tile data (originally from 2017) was updated to [September 2019](https://archive.org/details/osm-vector-mbtiles).
3. The world view (planetwide OSM vector maps included with all Map Packs) increased zoom levels from 0-9 to 0-10 (1.74GB osm-planet_z0-z10_2019.mbtiles) so that city search is successful more of the time.
4. Multiple Map Packs can be downloaded/installed (one "continent" at a time). However this can waste disk space with duplicate data ("continent" bounding boxes have been designed to overlap on purpose, so that multiple Map Packs are rarely necessary!)
3. **Hi-Res Satellite Photos** can be downloaded/installed for any 100 x 100 km, 300 x 300 km, or 1000 x 1000 km square region (around any map point that you click!)
1. These new Hi-Res Satellite Photo Regions are "squares" with 4 additional levels of satellite photo zoom (i.e. zoom levels 10-13) giving you 16X the resolution (i.e. 19 x 19 m pixels) and 256X more photographic information density.
2. As compared to Lo-Res Satellite Photos i.e. zooms level 0-9 (305 x 305 m pixels) everywhere else on the planet (932MB satellite_z0-z9_v3.mbtiles is included with all Map Packs). (SEE 2. ABOVE)
2. As compared to Lo-Res Satellite Photos i.e. zoom levels 0-9 (305 x 305 m pixels) everywhere else on the planet (932MB satellite_z0-z9_v3.mbtiles is included with all Map Packs). (SEE 2. ABOVE)
3. Multiple Hi-Res Satellite Photo Regions can be downloaded/installed (one "square" region at a time, thankfully duplicate disk space is avoided when such "squares" overlap!)
4. Some variables have newer meanings:
