Back in 2001, the local telephone company in our area (Northern Arkansas Telephone Co) undertook a project whereby each and every telephone pole was identified and mapped using GPS technology.Â To accomplish this task, a small group of NATCO employees were equipped withÂ ATVs andÂ GPS units.Â After spending each day following the telephone lines and entering each pole as a way point on their GPS units, the team would then upload this information into the NATCO computers, and thus an accurate survey of NATCO’s telephone poles was completed.
When the NATCO ATV showed up on our ranch to survey our poles, I took the opportunity to talk to the technician, and I became intrigued by the notion of mapping out the features of our ranch.Â I saw that the equipment that he used was fairly simple stuff, which gave me the necessary impetus to undertake a mapping project of my own.
Back when Retta and I were cruising among the Channel Islands off the California coastline, GPS navigation was a necessity, so I was quite familiar with GPS units and their capabilities.Â Our GPS unit was tied in to our laptop computer.Â The end result was that we could do our chart work in real-time, with the location of our vessel accurately depicted on our electronic maritime charts.Â When we sold the vessel, the GPS unit went with it, but now, here was my excuse to justify the purchase of an inexpensive hand-held GPS unit (I confess toÂ a personal weakness thatÂ prompts me toÂ tryÂ and find any justification for acquiring new technological gadgets).Â So I purchased a Magellan GPS device, and soon had it wired to my laptop computer.Â I also needed some type of mapping software, and settled on Delorme 3-D TopoQuads.Â This software is fairly full-featured and inexpensive, and while it is accomplishing all that I want it to do, it seems somewhat cumbersome to use, as if it were designed in a prior software era.Â Now, all I had to do was tie this all together into a package that could actually be used on the ranch. Here is what eventually evolved from my efforts.
Notice the following features of my “super-duper, multi-purpose, portable cartographic data collection machine”Â (SDMPPCDCM).
A) High-tech Rubbermaid containers are utilized to house the necessary components, as well as providing sun-shading capabilities for daytime use.Â These are inexpensive, readily available, and coincidentally, just the right dimensions to fit snugly into our utility vehicle.
B) This applicationÂ for aÂ laptop computer consumes lots of power.Â The computer cannot use any power saving modes while mapping, the screen must be set for full power to be visible in the daylight, and the hard disk drive and CDrom are always busy performing mapping chores. Rather than trying to createÂ a properly conditioned power supply from the utility vehicle’s electrical system, which would have been a project unto itself, I opted to power the system with an automotive rechargeable booster pack, availableÂ (of course) fromÂ our local Wal-Mart.Â By adding a simple and inexpensive power inverter, this system can be operated at full power for a lot more hours than I care to work in a day.
C) The laptop is affixed to the turntable by a pair of stabilizing rails on the side of the turntable, and secured with industrial Velcro attached to the bottom of the computer.Â The turntable swivels on a simple pivot, allowing me to easily adjust the viewing angle.Â The entire package is secured to the vehicle with a heavy duty bungee cord.
D) The GPS unit, which feeds data to the computer via a data cable, is mounted on the dashboard of the vehicle with a quick-release mount built especially for this particular GPS unit.Â This allows for excellent visibility while driving, and allows me to easily pop off the GPS and use it on foot when necessary.
When mounted in the utility vehicle, the entire contraption appears as below:
An example of the results obtained with this system can be seen in the following map printout, which is a screen shot from the Delorme mapping software.Â This particular map layer that isÂ picturedÂ shows the trail network as it exists on the ranch.Â There are unlimited layers available, and I have used them for many purposes.
You may ask, “Hal, what prompts you to spend so much time rambling on about computerized mapping systems and such?”Â Â Pablo, editor of the Roundrock Journal, a fine and highly popular Missouri blog, recently mused about solitary shag bark hickory and walnut trees on his property.Â The question arose as to weather solitary trees of this type would produce nuts.Â I suppose a normal person who is motivated to find an answer to this question would, with a few well-defined queries to Google, come up with an answer in short order.Â But I am (thankfully)Â not normal!
Three years ago, I began a long-term project of mapping the approximately 150 black walnut trees that exist on the ranch.Â Each year, I use my GPS data toÂ locate each of these trees, and I note their status as being either “nut-bearing” or not, as the case may be.Â I then use this data to plan my bush-hogging schedule, so that the trees are accessible to my friend Jasper when he comes around in the fall to gather our black walnuts.Â It is my thought that I can utilize the data that I am collecting to answer the pressing question of solitary nut trees (if I should be fortunate to live long enough to collect a meaningful amount of data).Â I am also attempting to see if I can find any direct correlation between nut production and weather patterns.Â This may be grist for a future post (if I can find any resultsÂ worth posting).
At first I thought you were wearing the Tupperware on your head for sun protection.
Your neighbor’s “L” really intrudes into your ranch. You should buy it off him.
My friend Jasper who gather’s nuts is a squirrel. Yours?
Tupperware hat…hmm…hadn’t thought of that.
That neighbor’s parcel is over 500 acres, so I thought they might jump at the chance to sell off 40 acres for well over market value – they turned me down flat. Said that it was all held in trust for their kids and grandkids. Fortunately, they do not use that 40 acres for anything other than buffer, so it works out OK for us. Besides, their house is located on the map just above “Cattleguard” on the west side of our property. We have a mexican standoff – they have property just behind our house, but we have property just behind their house. It makes for good neighbors.
Our nut gathering friend Jasper is the same gentleman who is teaching us to course bees. He’s not squirrelly, but he is as nimble as a squirrel :>)
I don’t know how much disk space you have on your laptop, but if you have enough, you can prolong your battery charge by doing creating a disc image of your CD-ROM based mapping software. You can mount your CD images on virtual CD-ROM devices. Very efficient.
Unfortunately, this laptop only has a 1GB drive. It also only runs at 133MHz. It’s running a minimally configured OS, but with the software I need to have installed, I’m only left with a small amount of free space, which I need for my swapfile. I suppose I could compress the drive, but that has usually led to problems for me in the past. The bigger problem is that it is painfully slooooooow! Elapsed time from power-up to loading of Delorme mapping software is nearly 5 minutes. But, with all of that, this setup seems to get the job done….I’ll just have to keep looking for other reasons to replace it.
I see. Well then, perhaps its time to feed that laptop to the turkeys. 🙂
