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

Three PDF maps cover the Ventana/SilverPeak region - see overview map below
(3 maps to match Avenza "free" limit )
To download PDFs:
(1) To app directly:  on table below, "copy" desired file URL (using long press), then "paste" into app's import page (for Avenza, use "+" icon on "My Maps" page).
- OR -
(2) To smartphone folder:  on map below, left click on displayed ID of desired region 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)

Geospatial PDF URLs

Avenza Users - add a searchable KMZ layer
A name search for a "Feature" (aka "Point of Interest"), the map then displaying its location, is made possible in Avenza by "importing" a "Big Sur Trailmap Features" KMZ file as a "layer" and "linking" it to the corresponding PDF map. 
To download Feature KMZs to Avenza:
On table below, "copy" the desired file URL (using long press), then in Avenza's "Layers" menu select the "Import Layers" option and "paste" the URL into its "From the Web" selection.  (Or type the URL instead of a copy+paste.) When the download prompts you to "Link" the file to a map, select the associated PDF map (the "link" also can be made after downloading)(See Avenza help for articles on "Importing Map Features" and "Searching a Map".)
These searchable KMZ layers are new - if you notice a problem, let me know so it can get fixed!
Usage Notes:  a "Feature" icon (small) is displayed atop the underlying Trailmap icons (unless made "Hidden" - see Note below) - such icons can be touched to display their name and, if the name popup is then touched, a description with additional information.  FYI, I have included trail/road end points as "Features" so you can also search for trails (note: for those, no icon will be visible)
Note:  a downside of using this layer is its linked map becoming slower to load.  If that is a problem, it can be mitigated by toggling the "Visibility" of the layer (using the "Layers" menu) so all features are "Hidden" and so not automatically loaded and displayed - then when searching for a feature, before moving the map to a found "Hidden" feature Avenza will ask if you want to make that feature "Visible" on the map, as is necessary for the search.  Having only previously selected features "Visible" greatly speeds up map loading time. 

"Feature" KMZs for Avenza "Layer"

Technical notes:
Maps are updated weekly:  last update Dec 6
Resolution ~2.1 meters/pixel
File sizes:  VentanaNorth, VentanaSouth, SilverPeak= 66, 61, 38 Mb
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.  To distinguish between close-together stream crossings the map must be at its highest zoom level, else only a single icon is seen (this is also why the icon must be small)
