[pct-l] Announcing eTrails 1.3

[Dan C. aka Thumper]

I agree that having Halfmile's maps loaded onto a phone or tablet device is far better than loading the maps onto a handheld GPS device.  The reason is all of the notes would block some of the viewable map.

But, his maps could be geo-referenced using Adobe Acrobat Pro.  Each page would need to be saved as it's own file.  Or you could splice several pages together into a single file.  Then you would need to have accurate coordinates for the 4 corners of the map.  It's lots of work for little or no gain.

Also, if Halfmile wanted his product to be geo-referenced I'm reasonably sure he would have published them that way.  I suspect he doesn't for some very legitimate reasons.  Like the previous post stated, use his track and waypoint files on your handheld GPS.  They work great.

Actually you don't use (in electronic devices) Halfmile "maps", you use his tracks and waypoints (downloaded GPX files) and those are very accurately georeferenced.
I use them with Backcountry Navigator and I'm very happy with the results for thru-hiking, biking, training, and RVing. I load the GPX files on top of the free Caltopo maps.

You can download Lon's map in PDF form into a phone and I did as a third backup .... seemed SUL to me.

I also carry his maps in paper form as first backup with compass but have never needed them.(2-4 oz depending on resupply days)

I'm going to download eTrails 1.3 and see how I like that too.


'til later

Half-mile's maps aren't georeferenced and so can't be used as you would
like. It would however be great if they were.

Somebody please correct me if I'm wrong.
