-## What's Changed in Maps for the IIAB 7.2 Release?
-1. Two variables in /etc/local_vars have new meanings:
-    1. Osm_vector_maps_install means install the map program (about 40MB).
-    2. Osm_vector_maps_installed means install a functioning world map to zoom 10 (about 2.8GB). 
-2. There is a new installer page, separate from the Admin Console, with installs regions and downloads higher resolution satellite imagery from zoom 11 to zoom 13 (16 times the resolution provided by zoom 10j).
-3. Multiple vector OpenStreetMap regions may be installed, and viewed on the same map.
-4. Multiple regions of satellite improvements can be added to the same map.
-1. The region size for satellite downloads can be adjusted to 50, 150, or 500KM around a selected map point.
-1. More recent OSM data is used in the vector tiles (2017 => 2019).
-4. Increase the base install  (world view) from zoom 9 to 10, so that city search is successful more of the time.
-5. There is a new drag and drop feature which permits the student to add descriptions and pictres about local points of interest, and then save and restore them using their local browser.
+## What's New with IIAB Maps for the IIAB 7.2 Release?
+
+#### See also the [IIAB 7.2 Release Notes](https://github.com/iiab/iiab/wiki/IIAB-7.2-Release-Notes).
+
+1. There's a new **Install IIAB Maps** page (http://box/osm-vector-maps/installer/) with [instructions](https://github.com/iiab/iiab/wiki/IIAB-Maps#how-do-i-install-map-packs-and-satellite-photo-regions-on-iiab-72-), separate from IIAB's Admin Console:
+   1. This [very visual page](https://user-images.githubusercontent.com/2458907/94740848-46c4eb00-0341-11eb-93ea-e3e4758dce48.png) facilitates selecting/downloading/installing of Map Pack(s) for your favorite "continent(s)".  (SEE 2. BELOW)
+   2. And then likewise for Hi-Res Satellite Photo Regions serving your local communities.  (SEE 3. BELOW)
+
+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.  Read more at: https://github.com/iiab/iiab/wiki/IIAB-Maps
+   2. Map Packs' OSM vector tile data (from 2017) was updated to data from [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 (and "continent" bounding boxes have been designed so that this is 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)
+   3. Multiple Hi-Res Satellite Photo Regions can be downloaded/installed (one "square" region at a time, even if they overlap!)
+
+4. Some variables have newer meanings:
+   1. `osm_vector_maps_install` in [/etc/iiab/local_vars.yml](http://wiki.laptop.org/go/IIAB/FAQ#What_is_local_vars.yml_and_how_do_I_customize_it.3F) means install the map program (about 40MB).
+   2. `osm_vector_maps_enabled` in [/etc/iiab/local_vars.yml](http://wiki.laptop.org/go/IIAB/FAQ#What_is_local_vars.yml_and_how_do_I_customize_it.3F) is once again standardized, solving #2484 install delays.
+   3. `osm_vector_maps_installed` in `/etc/iiab/iiab_state.yml` means a functioning world map with 7 levels of zoom (z0-z6) has been installed — i.e. a preview of IIAB's mapping system that helps you select Maps Pack(s) and Satellite Photo Region(s) to download and install on your IIAB.  (SEE 1. ABOVE)
+
+5. **Drag-and-Drop Map Overlays** — try this by dragging and dropping any relevant GeoJSON file onto the IIAB Maps (http://box/maps) in your browser!  For example try this GeoJSON file, to explore the shape of gerrymandered US Congressional districts: https://eric.clst.org/assets/wiki/uploads/Stuff/gz_2010_us_500_11_20m.json
+
+6. Separately: Students can _right click_ on IIAB Maps (http://box/maps) to **add descriptions and photos** of local points of interest — and then save and restore them using their local browser.  [CAN ANYBODY SUGGEST STUDENT/TEACHER GEOGRAPHIC ADVENTURE & LOCAL EXPLORATION TIPS THAT WORK ON PHONES?]
