Description
The S1 Mobile Mapper is a custom mapping and field data collection Android application built by the Oregon/Washington (S1) Mobile GIS development team, sponsored by Oregon State Office Bureau of Land Management.
For the public S1 Mobile provides offline mapping capability that provides download capabilities for official Bureau of Land Management Maps for Oregon Washington & US Forest Service maps throughout the US for offline use. Maps that are distributed are free maps that are already publicly available and have gone through the appropriate agency public affairs process. Application includes GPS capability so that you can see where you are on public land even when not connected to any cell network (note that maps must be downloaded to device in order to see them offline). Additionally the app includes the ability to take waypoints, GeoTag photos and basic navigation as the crow flies.
For government staff (currently available to Bureau of Land Management, US Forest Service, USGS and National Interagency Fire Center) S1 is designed to extend offline mobile field data collection capabilities not available using commercial ESRI mapping applications and to meet the specific data collection needs of the federal agencies served by the OR/WA Service First Mobile GIS program. The application leverages each agency's ArcGIS for Organization (AG4O) site as well as their internal ArcGIS Server deployments to distribute, collect, and update enterprise geographic information systems (GIS) information by agency field personnel.

★★★★★
Excellent application. Really helps with data collection and sharing. Offline Forest Service maps are wonderful.
★★★★★
This app is great for offline data collection. Also has great recreation maps for FS and BLM recreation areas. Nicely done!
★★★★★
I really enjoy the use of tile packages and streamlined, standardized data collection and management of this application. The set-up with geodatatbases and Arc GIS Online takes a bit, but it leads HUGE efficiency savings with near realtime data syncing. On the timber preparation side of a timber sale contract package it increased our operational efficiency by 30-50%. In heavy canopy and ruggedized terrain you may need an additional Bluetooth GPS antenna such as Garmin glo to work quickly.
★★☆☆☆
It won't open because I won't allow the developers to use the camera to spy on me. Why does this program have a need to control and make phone calls needs access to my photos and needs the camera to spy on me? I was hoping to use it for maps.
★★☆☆☆
App simply didn't work for me. It showed a map of the US and wouldn't or
couldn't find and load any maps. If had no BLM data. It was just a bare
app. I don't see its usefulness.
★★☆☆☆
On my pixel 2, it wouldn't download any of the maps. I've upgraded to a s22, and now the maps download, but none of them will display. Truly a bummer, as this would have been an amazing app if it worked :(
