Big Sur Trailmap Geospatial PDF Maps

Many trail/camp locations on USGS/­USFS/­WildernessPress/­NationalGeographic/­Garmin maps of the Big Sur Ventana & Silver Peak Wilderness Areas are incorrect - these geospatial PDF maps from the on-line Big Sur Trailmap provides accurate trail and camp locations based on local knowledge (mostly GPS'd), and also locally-known "use trails", water sources, waterfalls, and other features in the Ventana and Silver Peak Wilderness areas and in Big Sur state parks. 


Smartphone GPS apps Avenza Maps (free for 3 maps, else $30/yr) and Mappt ($30/yr) can utilize these geospatial PDF files (more info)
Also Adobe Acrobat Reader for viewing - but it is not a GPS app and cannot display your current location
Note:  these files are too large for some PDF apps.  They were useable in Adobe Reader on desktop and android smartphone - but I've also had difficulties on smartphones.
If you know of other apps with the same capability, let me know so they can also be linked here
These geospatial PDF maps are new - if you notice a problem, please let me know so it can get fixed!

Overview map below outlines the PDF map coverage areas
(3 maps to match Avenza "free" limit )

For PDF download:
(1) To app directly:  "Copy" desired file URL from table below (using long press), then "Paste" into app's import page (for Avenza, use "+" icon on "My Maps" page).
- OR -
(2) To smartphone folder:  left click on ID of desired map to download, then use smartphone "Import" to import file into app.  (Note: this may fail if the smartphone wants to automatically display the PDF file, as iphones are wont to do, since the files are too large for some PDF apps)

Technical notes:
Maps are updated weekly:  updated Sep 19
Resolution ~2.1 meters/pixel
File sizes:  VentanaNorth= 66Mb   VentanaSouth= 61Mb   SilverPeak= 38Mb
dots mark intersections with mileages between them displayed near their mid-point (if greater than 0.2 mi)
icons mark stream crossings on trails which cross the same stream multiple times (e.g., the Carmel River Trail crosses the Carmel River 27 times), since knowing whether the next crossing is near can be useful.  But the icon must be small since if larger would show only a single icon at close-together crossings, negating their usefulness.  So if hiking such trails, displaying the map at its highest zoom level is needed to effectively display the stream crossing information.
