A desktop app with its own map engine: 3D terrain, a globe view, terrain tools and ZYRNTOPO's maps, offline, on the same account and data as the phone app.
A working copy of the ZYRN Workstation window, running in your browser. The Map tab tools and the search box work: try Camp Muir, Nisqually Glacier, 46.85, -121.76 or 10T ES 94815 89385.
On the desk
Room to plan a search and brief a team.
ZYRN Workstation fills a full screen: a ribbon of tools grouped by task, the map in 2D or 3D, and a status bar that always shows where the cursor is in latitude and longitude, UTM and MGRS.
It uses the same account, saved items and file formats as ZYRNTOPO in the field, so a plan made at the desk opens unchanged on the teams' phones and tablets.
- 3D terrain and a globe view
- Toolbars for search and rescue, range and bearing, and terrain
- Import, export and print true-scale map sheets
- Team Sync and TAK on the same map Pro
