By Jay, on May 8th, 2012% 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 . . . → Read More: GIS Services Offer

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.
Site Location of Bedrock Outcrop along US-401 South, Raleigh, North Carolina – photo by J. Sents, 2012
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.

I’ll have a really exciting announcement on May 2. It’s in the realm of environmental geology, hydrogeology, data management, GIS, and my all-time most favorite subject, three-dimensional data visualization and numerical computer modeling. So cool. Stay tuned!
By Jay, on March 19th, 2011% This is a rather unique combination of remote sensing and GIS applications for data visualization of tsunami damage in Japan. Remote sensing is defined as the technique of obtaining information about objects through the analysis of data collected by special instruments that are not in physical contact with the objects of investigation [Avery & Berlin, 1992].
Remote sensing plays a role in GIS [refer to this post] since the data collected in this form of “reconnaissance” can be geo-rectified and aligned with other useful data that have undergone a measured survey defining their location on Earth. Remote sensing of cultural, populated, or other land use areas [agricultural, forestry, ecology, etc.] on the surface of Earth is usually accomplished using photogrammetric tools. This can be film or digital photography from aircraft or orbital satellite platforms.
I think you get the idea. The combination of remote sensing and GIS is pretty cool. The second part of remote sensing is the analysis of the data, in this case, hi-resolution photographs comparing the before and after damage on the surface of Earth across the west coast of Japan. Instead of a typical side-by-side comparison, the authors presented the data in a unique visualization layer . . . → Read More: 2011 Japan Tsunami Unique Visualizations

Looking around town ahead of some warmer weather and outdoor activities, I checked out the Wake County GIS Internet Multi Access Parcel System. A mouthful for sure. We can just call it IMAPs, or interactive maps to keep things simple here. This system is so cool for looking up places to check out geology, do some forward recon for photography, or just snooping around in general. What is it?
IMAPs is a Geographic Information Systems [GIS] interactive, web-based tool published by Wake County and Raleigh, North Carolina. I believe there may be some coordination between the municipal end and North Carolina State University and UNC Chapel Hill. What is GIS?
GIS is an approach to mapping electronic data stored in a database. It’s extremely useful because of the way things are mapped. Data are queried in a transparent fashion behind the scenes from a relational database, and then filtered, organized, and managed on individual sets of digital drawings. These drawings are referred to as layers. Think of each layer as a sheet of clear paper with one type of data drawn on it: roads for example. Another layer may have rivers. And another layer may contain land use information [wilderness, . . . → Read More: Interactive Online GIS Tool
