About this app
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.

If this works as well offline as it seems it should, it's extremely cool. Requires knowledge of topographic maps, even then it's not super user friendly, but not too bad. It's meant for use in remote areas, not everyday map use, you can't ask it for restaurants. However having every single forest service and blm map in full detail for an entire region always ready is pretty awesome. The gps tracking seems excellent, but will require further testing.

Thanks for your review! It is intended specifically for offline use. Make sure to use the gear icon & "download maps" option to download your offline maps before heading out to recreate. The main intent is to provide access to authoritative and up to date BLM and FS maps. There is a user guide available if you want more details on functionality.

Having worked with GIS systems before and needing to find where BLM land and others, this app is perfect. It may be hard for the average person but to people requiring a specific app for a purpose, couldn't ask for more.

Hey Kevin, thanks for the review! Glad to hear the app is working well for you. Please also feel free to use the feedback option directly in the S1 app or from our S1 public webpage https://www.blm.gov/services/geospatial/mobile-GIS/s1mobile, if you have ideas for improvements.

On my pixel 2, it wouldn't download any of the maps. I've upgraded to an 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 :(

Hey Nastia,
The Pixel 2 device not working correctly is possible, but we have done testing on S22 series devices and you should have no problem using the app in public mode and downloading the available basemaps on that device. Ensure all the permissions that S1 requests are enabled. Demo: https://youtube.com/shorts/Q8hX8FGvrKE?feature=share
