GIS Services Offer

Here’s something regarding Geographic Information Systems [GIS] sure to grab someones attention. One of my main advertisers, LumiViz, is holding a Month of 10% Savings of GIS Services special offer. LumiViz is a small computer-based geoscientific mapping, modeling, and visualization services outfit with an extremely impressive array of technical experience and applied skills.

LumiViz is high-energy, and they promise to have more of these special offers for different software environment service areas as time goes on. I’ve listed the guidelines and rules for the GIS Services 10% Savings Month offer below.

General:

    • All transactions, correspondence, calculations, communications, and output are to be completed in English and US Dollars;
    • Work tasks associated with this limited time special offer will be completed inside the ESRI ArcGIS 10.0 environment;
    • Out of scope services will be categorized as a different Purchase Order under the full, standard rate for LumiViz GIS Services;
    • Offer only valid for Purchase Orders executed and signed between May 9, 2012 at 12:00:00 a.m. Eastern Daylight Time until June 9, 2012 at 11:59:59 p.m. Eastern Daylight Time;
    • A fixed point of completion will be identified and codified in the Scope of Services (Scope of Work) and Purchase Order such that there is a definitive end-point in work completed as part of the 10% Savings offer;
    • LumiViz Certificates of Insurance will be provided during preview of the Scope of Services; and
    • Scheduling for multiple potential clients’ projects will proceed on a “first come – first serve” basis with minor adjustments based upon individual client schedules.

Business-to-Business:

In a direct agreement between LumiViz and a client business, a draft Purchase Order will be generated. Once agreement to the terms above has been reached, LumiViz will adjust its rates to match a 10% discount on the total cost to the client, and a Final Purchase Order will be signed.

Third Party Broker:

An opportunity exists for an individual to act as a third party broker between LumiViz and a potential client for the term of the offer. The third party broker must first contact LumiViz to state their intention. This is best done via e-mail to adequately establish a time stamp (for scheduling purposes). Next, the third party broker should introduce the potential client to LumiViz. Once complete, the potential client and LumiViz will proceed with a Scope of Services (Scope of Work) and Purchase Order at the full, standard rate for LumiViz GIS Services. If the Purchase Order is accepted, the third party broker will be awarded 10% of the total Purchase Order. To clarify, the potential client in a third party brokerage will NOT receive the discount; however, the broker WILL receive 10% of the cost of the Purchase Order. Third party brokers have every liberty to split their 10% however they wish for incentive purposes (5% to the broker and 5% savings to the client). Payment of the 10% to the third party broker will commence as soon as the invoice cycle terms of payment become effective and realized by LumiViz (this can range anywhere between 30-90 days, sometimes shorter or longer). LumiViz will NOT be held responsible in any way for conflicts of interest based upon the third party broker’s current employer or other financial limitations.

This is pretty cool. It definitely says that the larger the project, the larger the savings for a potential client. For any third party brokers, it’s a chance to brush up their marketing skills. And, I can see that there is a huge benefit in search page rankings for LumiViz and increasing their network with other industry professionals. Any ways, good luck to all involved. I am eager to see how this turns out. If anyone has anything to say about the results, feel free to comment in this blog post. I have a million things to do, so I might not be able to squeeze that strike and dip lesson in before next weekend.

Raleigh Bedrock Outcrop

The Raleigh, North Carolina area is a peneplain. The area has been devoid of any mountain building events for quite some time so the land surface has very low relief. As a result, outcrops of exposed metamorphic bedrock across the Piedmont physiographic province are few and far between. Additionally, bedrock may be covered by a literal veneer of dense soil and/or saprolite which conceals the bedrock below by mere inches.

But fear not!  I am a trained geologist and have become adept at finding these obscure bedrock outcrops.  So for reference, and in case anyone wants to go and visit, lets start with a map that I cobbed together.

I used the Wake County iMAPS GIS [Beta] for the base layers used to create the map above.  The location presents itself as an unpaved, unmarked parking lot.  Along the southern edge of the lot, a stand of trees and bushes conceals the exposed bedrock.  So a few days after the initial identification of this site, I made first contact with my camera and compass.

You can see my Brunton compass just to the right of center [the bright object].  Don’t ask what string was for.  I can’t imagine anyone went out of their way to hold that scrawny tree upright but who really knows?  I’ve seen weirder things across this state.  Note as the outcrop starts to become saprolite [extremely weathered bedrock] to the right [west].  See what I mean about how little soil cover is required to start obscuring the bedrock?  This is very common across this whole Piedmont region.

Another thing to note is the set of joints and fractures.  I sampled these and collected the strike and dip data.  I will present those below.  For those of you who have no idea what strike and dip are, I’ll explain that in a follow-up post very shortly after, if not immediately following, this post.  Here are some strikes and dips of the two predominant fracture sets:

  • 255° 75°NW
  • 258° 73°NW
  • 256° 75°NW
  • 317° 65°SW
  • 315° 72°SW
  • 318° 69°SW

I’m far more concerned with the strikes [bold] than the dips [gray].  What I’m hoping to accomplish is to present you all with a better idea of what I find, how it compares to the work the North Carolina Geologic Survey is currently conducting, and what it tells us with respect to the regional Piedmont metamorphic bedrock in central North Carolina.  Stay tuned.  I’ll get to the strike and dip definitions tomorrow most likely.

 

I Found a New Outcrop

It was hiding in plain sight.  Let me get through some other issues and then I’ll post some pics, the location, and the structural information…

Online Geoengineering Library

Check out this web page for the Online Geoengineering Library powered by Geoengineer.org. I haven’t given it a rigorous test yet since geologic engineering and geotechnical are not my primary fields, but it looks pretty nifty:

A Quick Photo

Well, I say quick, but not entirely. It took me 3 hours to hike up to this location. Then I saw this scene. I thought it looked pretty cool but knew it was going to be difficult to develop unless I went black & white.

The location shall remain unnamed for now. I’ll give you a hint though: I’ve been here before and posted some other photos from this place. It’s a long story that I hope to have cleared up in due time.

Enjoy this Day After Thanksgiving photograph:

2011 Daylight Savings Time Ends

Sunday November 6th, 2011 at 0200 hours [that's 2:00 a.m. to most], your clocks will have to “fall back” one hour. So 2 becomes 1. It would probably work just the same to set them back one hour before you go to bed Saturday night [tonight].

Now is an excellent time to check your smoke alarms and carbon monoxide detectors, as well as other household battery-powered emergency alarm systems.

Finally, be sure to update the clocks in your automobiles. Be safe driving until you adjust to the light conditions, and enjoy sleeping in Sunday morning!

Interesting Sticker

I found this bumper sticker that pretty much sums-up where we are at here in the US:

Copper Fragment Update!

The predecessor post to this one below lays out the story of the mystery fragment of copper I found at Kure Beach, North Carolina near Fort Fisher. So I gathered up some photographs and sent them along to the Underwater Archaeology Branch of the North Carolina Office of State Archaeology. Here is the reply verbatim:

It looks to me like an expansion ring from a 40mm Bofors machine gun/cannon projectile. The projectile was steel but the copper expansion ring was designed to catch the rifling in the barrel and often broke away when fired. The grooves that are visible in the “lighted relief” photo look like rifling marks. In the attached photo you can see one that remained on the projectile after firing–this one was found on Kure Beach also.

Anyway, that’s my best guess. We see dozens of those things every summer when people are out beachcombing. Kure Beach was an artillery training camp during WWII, focusing on anti-aircraft weapons practice. Evidence of this activity is all over the beach, primarily the result of beach renourishment where a dredge boat removes sediments from offshore (where the bullets land) and pumps them on the beach.

Pretty cool, huh?  Not a centuries-old fragment of sunken pirate treasure, but some history nonetheless.  Case closed as far I’m concerned.  Well move on to the dredging and some of the coastal erosion aspects of Kure Beach in another post.

Marine Concretion on a Copper Fragment

Earlier in the Summer on a trip to Kure Beach, North Carolina, I just happened to find a small piece of copper in the Coquina Rocks.  In a nutshell, the Coquina Rocks are essentially a partially submerged outcrop of sedimentary rocks found near the southern end of Kure Beach near the Fort Fisher Recreational Area.  More on Coquina Rocks later…

I was walking along, carefully maneuvering through the Coquina Rocks during during Maximum Ebb Tide this one day. Many people apparently scout the micro-lagoons formed in the cracks and crevasses of the rocks during Low Tide looking for sharks teeth. I really don’t care for sharks, let alone their teeth but these people do. I looked down and saw a gold-red glint with a hint of bright green. Below are some photographs of what I found:



The rule is for scale. It is a standard engineer rule with 1/10th-inch graduations. What is the green stuff? Well that would be considered a marine concretion. First, the environment here is [or has been] oxygenated enough that copper and copper alloys would corrode and oxidize. Chemically unweathered copper is a golden, reddish-brown in most cases. An oxidized copper surface is usually black before becoming green in the presence of saline seawater. Ancient copper artifacts and older statues made of copper tend to take on a greenish hue once oxidation of the copper has progressed, for example.

Closer inspection of this weathered, oxidized copper fragment reveals something more: detritus. Detritus is small grains of sand or clay mud clasts. Detritus is by most definitions, small particles or debris that have been broken away from a solid mass or other substrate. Visual observation and logic show that detritus has been incorporated in the crusty, green, oxidized coating on the outside of the copper surface:

The marine corrosion that oxidizes the copper forms a chemical crust that acts as a hardened glue, or cement. Loose grains of sand are trapped and incorporated in the cement. All of this is bonded to the surface of the copper in this case. That’s what makes it all a marine concretion.

Now here’s the super-cool part.  Upon closer inspection than before, and under the correct lighting, there is an even more intriguing observation.  There are straight, parallel, and equally-spaced lines or marks in the surface of this little fragment.  I’ve used a technique to side-lighting often used in aerial photography [they take the photos in the morning or at sunset] to accentuate the relief across one face of this fragment.

Stay tuned for sure!  I have some people from the North Carolina Office of State Archeology looking into this because these markings on the copper fragment definitely show some Human intervention.  Could it be a piece of historic American Civil War ammunition from Fort Fisher?  A little bit of metal banding from a shipwreck like that of Queen Anne’s Revenge?  Something from a pirate?  Arrrg!!
