Change Log

September 2025

• Removed National Scenic & Historic Trails due to ownership and data issues. May return later
• Removed LCDO Trails from the New Mexico MMPK (GTLF Trails encompass these trails)
• Removed State Clipping Boundaries from export to remove duplication and confusion
• Added BLM Administrative Unit Boundaries and Point locations
• Added public BLM Trails data from the Ground Transportation Linear Features dataset (GTLF)
• Added 20FT Contour Vector Tile Package for entire USA
  • Displays at three different view ranges
  • 100 FT contour lines labeled
  • Can turn off in Layers menu
• Updated ESRI Navigation Base Layer to July 2025
  • Edited style to remove features that conflict with official BLM boundaries and SMA data
    • Vegetation
    • Wilderness/Study Areas
    • Forests and other park features
    • Ocean and other water features
    • Various other features that conflicted with BLM data
  • Now ‘transparent’ to allow for future display of imagery or other basemaps behind data
• Adjusted BLM SMA layer transparency from 40% to 50% to better show basemap data underneath
• Re symbolized all layers affected by MMPK legend duplication bug using Arcade driven symbology scripts
  • SMA, Recreation Point Features, Place Names, etc.
• Disabled various attribute fields not needed in the field
• Removed some incorrect Recreation Management Area features
• Refined labeling on various layers and toned down PLSS grid lines
• Adjusted all layers to display more logical attributes when identified (tapped on)

March 2025

• Surface Management Agency (SMA)
  • Made Private SMA hollow so features underneath stand out.
• Trails data
  • Added trails for Las Cruces District Office (New Mexico).
• Recreation Points
  • Users reported issues with the Recreation Points layers having the wrong symbols. After looking into it, the original layer was symbolized by the wrong attribute which resulted in items missing, items being grouped that shouldn't have, and other issues. The layer symbology was rebuilt into one layer using Feature Subtype instead of Feature Type and re symbolized. Features with a count of zero were removed and will be reviewed after updates and re added if the count goes above zero. Thanks for the reports!
• Recreation Polygons
  • Re-symbolized polygons to match the new BLM Recreation Cartography Standard for these features.
• PLSS
  • Thinned township and range lines to not overwhelm the screen.
• State Boundaries
  • Changed the state boundary dataset used as someone in Wyoming noticed the eastern boundary was inaccurate. Previous dataset also had a lot of issues cutting off data on the coasts. New layer is much more accurate and better represents coastlines and islands.
• Geographic Names Information System (GNIS)
  • Added a subset of the GNIS Feature Points dataset for Points of Interest/Named points.
• Updated expiration to 120 days.

Frequently Asked Questions

1. How do I change from Metric to standard measurement units?

1. Open Field Maps. If in a map, back out to the main screen.
2. Tap on the user icon at the top right
3. Tap on UNITS
4. Tap on Measurement Units
5. Select the unit of your choice for each selection under that if desired

2. How can I use this with Imagery or Topo maps?

MMPK files contain all data for offline use. Raster data (imagery and topo maps) are very large files and having those in the MMPK files would make them extremely large to download. We have limited file space to host these.

We are looking at other solutions to provide features like this and working with ESRI to enable work arounds for their use.

3. Can I get THIS dataset added?

We understand, and we probably do as well. Since this is a national program, we are starting with national datasets, as we would like the same data to be available to all users. There are not standardized datasets for some of the data requested, so smaller local datasets may be added in the future to each state as available. Other datasets like Hunting Units are not BLM products, but we are looking at how we can provide them for use. This will require coordination between individual state Game and Fish departments and BLM.

Requested datasets:

• Trails
• Gates/Fences
• Hunting Units

4. There are some conflicting colors between the base layer and SMA data, can you fix this?

This issue has been resolved in the September 30 2025 map update using Arcade scripting to define symbology as a work around.
