Description
Subsurface Maps Offline is an app that allows SubsurfaceMaps.com users to download their maps from the cloud to their Android phone or tablet for use offline. Using this app you can view and edit your maps without the need for an internet connection. The app has a built in interface with Radiodetection equipment for recording depth when you mark new points. The app also allows you to take pictures, directly connect to a Bluetooth GPS/GNSS devices (no need for mock locations), and then upload all of your changes to the SubsurfaceMaps.com server for everyone else on your team to view.
The regular browser-based application is still the flagship product where you must go to create layers, change colors, modify your field layout, draw lines, etc. The offline app is a less functional version that allows you to do basic data collection and viewing offline.

Always putting intelligent solutions into preventing damage to underground utilities! Easy utility mapping app. Good-looking guy in that video also.

Great GIS Solution for Municipals and Water Districts

Great no-frills, everything you need and nothing you don't app for quickly recording underground utility locates and flexible enough to be tailored to your specific needs instead of safety blanketing the user with options they may/may not need. Specific to my case, I run it on an Telephone Armor 7, which is also my company phone. Problem comes, and this would be background programming, when a call comes in or another app sends an alert. Shutdown! Option to show over other apps would be nice.
