Hey Villager
I am not really familiar with all of todays tech stuff, heck I just learned to text last summer. I was in scouting till mid teens, the army for 14 years before they introduced GPS and then 10 years truckin with a paper map. Just never learned these electric ways so don't mind me I'm not nocken your way and hope you find the easiest way to go about it

I think I would be going with a high resolution topographic map here combined with maybe a Google Earth satellite image.
Find an online top map, print on transparency. Overlay that on a satellite image. Depends on the size of the terrain, how much forest, bodies of water etc. Under 20 acres you can see the whole thing.
I'm pretty familiar with all of the 100 acres at the BOL, no need for map. Compass is handy in the deep woods.

...." high resolution topographic map here combined with maybe a Google Earth satellite image."

Perfesser,. Thanks for the right term to search, and it's still a challenge,...cuz it's way more than 20 acres,more like 600....much longer than wide, and irregular, hence the intent to do this on a UTV with a buddy ,making/taking notes and/or GPS.....

So i have to take 2 images on normal screen orientation, and splice them together, then impose them on a gugle sat pic.
(I did similar with a previous property of square 100 acres, cutting, overlapping 6 sat images to make a large map with recognizable features and then had it blown up to 25x25 and laminated. Then we could add/move transparent stickies wherever to make features or uses.)
The gugle earth make-a-map pic can be turned 90 deg. to get the whole property length in one frame with reasonable resolution, but it won't print out that way. I guess you have to pay for that kind of feature. Also, they don't have a scale/distance device, or i just didnt find it yet.
If i'm walking lower than surrounding elevations of rock/granite/possibly iron content, will the compass maintain accuracy?
And, is GPS similarly affected , or not at all ?

Here are my uses for a GPS in case the satellite system goes down or for some reason, there was a need to offset the satellite system for security reasons and you find your GPS off by a few blocks.... or worse... if you want to go to a worse case scenario, another major world power chooses to jam the GPS signal:
1. Route planning: You can still use a GPS device to plan a route, squire time/distance calculations, and see multiple route options so that you can plan conduct a proper route estimate.
2. Declination: Your GPS will still give you the declination for your last location and current time. If you never managed to get that mathematical ecuasion down or are just feeling too lazy to get out your paper and pencil, your trusty GPS saves the day.
3. Moon phases and sunrise/sunset times: Planning a route also includes movement VS down times. Could be weather related reasons that you need to move during the day or night, or it could be a safety thing. But if you want to cover ground from one RVP to the next, then knowing sun up and sun down times are critical. OR just so you can see when is the best time to go hunting.
4. If your GPS has a digital compass, then you can use that as it doesn't use satellites for that function. If your GPS has an altimeter then you need to know if that is based on a sensor or the GPS function. Barometer is usually a sensor.
5. If you have a newer model then check if it says GPRS instead of GPS: Global Positioning, Radio Assisted System (GPRS) works the same way as GPS. But in North America and Europe, we have towers that carry the same GPS broadcast systems as the satellites. These are spread along the coasts to assist in shipping navigation and if you were ever frustrated by bad connectivity driving a car then you understand why they did that for ships (Kind of a safety thing). Those might still work if your loss of signal is weather related.
6. Storing locations: You can input via the cursor or grid a new waypoint and still mark it on your GPS for help in future planning like in point 1. You don't need to be standing in a location to mark it on your GPS map.
7. Reading grids: Even if you have a map, it tends to end at the edge of the paper. If you need a grid off your paper map or end up walking off your paper map, then your GPS map can still help. You can move your pointer or cursor around on your GPS map and get a grid and elevation for a point. Saves you having to look it up when your tired, at night, or if it's off your map.
8. Line of Site: Since your GPS would give you elevations regardless of its reception as part of its map function, it helps when you're looking for a vantage point (VP) as a point of observation, to see if another feature will block your view or as we call it testing your line of site (LOS). Great for checking if that hike up the hill is worth attempting in the first place.
9. Fishing times: Not a big deal, but outdoor GPS devices have this and it helps show when fish and game are more active.
10. Other uses: In case you run out of uses, then the screen can work as a makeshift flashlight while the battery lasts. After that, the GPS I find does a great job at holding your map down while you set your bearings on your compass. It doesn't leave dirt or mud on your map like rocks do.

Hope this helps.Happy New Year.

Well said

Thanks RedRhino,
This all helps me to get a picture of the possibilities, green as i am with this technology.
The GPRS was a useful distinction too. ....wondering if that is available in a unit designed for al weather exposure on a UTV, and could such a unit be easily flipped between the truck and the UTV??
I would welcome suggestions for the best unit for the purposes, especially for making a detailed map which can be loaded to a pc and shared with others.
Is it correct that a grid can be overlaid with this handheld unit?
I couldn't work out the following abbrev.'s :
VS and RVP ?

Check this one out. http://www.amazon.ca/Garmin-Oregon-450-Handheld-Navigator/dp/B00313JX4W/ref=sr_1_9?ie=UTF8&qid=1388958052&sr=8-9&keywords=gps

Mike, i just saw and visited your provided link and will explore it further. It seems to cover the intermittent celltower connection.
So, it looks like i have to buy a smart phone? which do you suggest with this function in mind. ( i would not use it frequently as a phone in regular time, but a few times a month and for remote/emergencies.
Also, if i plot out my area in this way, does that somehow become publicly trackable or recorded by gu-gle?
thanks, ...villager

I have a Samsung Galaxy Nexus, I like it. It's a bit dated now, I think the current models available are the S3 and S4, the Samsung Galaxy Note is a pretty capable device as well.
