Specifics on the Q2 2011 US-Wide Parcel Layer Release

Officially released last month by CoreLogic, the Q2 2011 US-wide ParcelPoint data layer features 14 new counties as well as updates to nearly 12.1% of the counties currently available.

Custom US Parcel Pricing for Pipelines, Transmission Systems and Corridors

Since eMap introduced its valued customers to the CoreLogic US ParcelPoint layer, it has been a popular offering for many markets including those in energy, utility and engineering. As a standardized US parcel dataset, ParcelPoint has saved geospatial professionals both time and effort in the sourcing, preparation and updates of their crucial land ownership records. With more than 2,200 counties in the database, CoreLogic's ParcelPoint is by far the most extensive source for land ownership records that can be found in a single location.

Satellites in the News - Aquarius

On June 10th of this year, NASA, partnering with Argentina’s Comisión Nacional deActividades Espaciales (CONAE), launched the Aquarius instrument into orbit at 657 kilometers above Earth’s surface. The Aquarius instrument is aptly named as its principle goal is to map the surface of the Earth’s oceans. The satellite is capable of mapping the entire Earth’s sea surface salinity once every seven days. This will allow researchers to compare the seas’ salinity on a monthly, seasonal and yearly basis.

Gone Fishing – Invasion of the Snakehead

In the US we have seen our fair share of invasive species including the Peacock Bass that made its way from the depths of the Amazon River to waters of South Florida; or the wild boar that has all but taken over most of North America. Truth be told, you probably encounter many invasive species throughout your lifetime that have been around for so long that are, for the most part, now considered native, such as dogs, cats and even elk. But there is one creature that has sounded the alarm for concern and even panic, the freshwater snakehead.

  

In Focus – Three Gorges Dam

The Three Gorges Dam is a hydroelectric dam located in the Hubei Province of China. It spans the Yangtze River near Sandouping and is the world’s largest power facility in terms of capacity at 18,200 megawatts. The dam body was completed in 2006, and the final components for it to be functional were completed in late 2008. Beyond producing electricity, Three Gorges also increases shipping capacity and helps control flooding. Plans for the dam started as far back as 1919, but the construction didn’t start until December 1994 due to many different reasons including economics, the lack of necessary engineering expertise and political interference.

High Resolution Satellite Imagery Shows an Increase in Rwanda's Forest Cover

In the late 1980s, the country of Rwanda's image began to shift from a socially and environmentally progressive society to one that had fallen on hard times due to a decrease in agricultural output and governmental change. Outside interest from countries supplying aid also began to change with their desire to see democratic reform. This eventually led to a civil war in 1990, where the Rwandan Patriotic Front, a rebel movement comprised of Tutsis, clashed with government and military fighters comprised of Hutus. In 1994, Hutus took control of the government and issued orders to exterminate all Tutsis.

  

Q: "Ongoing Geospatial Education?" A: "Penn State."

The Beaten Path – The Strategic Petroleum Reserves

The United States Strategic Petroleum Reserves (SRP) are the largest emergency oil reserves in the world with the capacity to hold up to 727 million barrels. The oil reserves are divided into two different categories, sweet and sour. The term sweet refers to a maximum sulfur content of .50%, while sour allows for up to 1.99% sulfur content. Approximately 60% of the oil in reserves is the lesser desirable sour oil; and there is a $15 discount in value for each barrel of sour oil. As such, the total SPR value is estimated at $85 billion dollars.
