Use QGIS to save satellite imagery for your phone (8 mins)
Suggestion: Use the long term release of QGIS, not the latest version
URL for satellite imagery: https://mt1.google.com/vt/lyrs=y&x={x}&y={y}&z={z}
Choose a small area – resultant .mbtiles file should be no more than about 1 GB
Create MBTiles files from WMS feeds (last 5 mins of video)
URL for WMS supplied by Geological Survey of WA: http://gissdi.dmp.wa.gov.au/GISexternal/services/External/Imagery_External/MapServer/WMSServer
Display scale bar:  From menu, View -> Decorations -> Scale bar 

Create a grid to manage your workings (7 mins)
URL for satellite imagery: https://mt1.google.com/vt/lyrs=y&x={x}&y={y}&z={z}
Note: This system does not work on Android devices with less than 2GB RAM
To set all grid coordinates to whole numbers, set the project CRS to the required UTM projection and after choosing ‘Use canvas extent’ remove all decimal points
eg. Grid extent:  337404,338369,6805642,6806307 [EPSG:32751]

Create an MBTiles map from a GeoTIFF map, using Maptiler (2 mins)
Additionally, MapTiler can convert ECW, JPEG200, GeoPDF and more formats to MBTiles.
Important: Choose JPEG format in ‘Advanced’ options to avoid problem with missing tiles when viewing generated MBTiles map on iPhones and iPads.
