1. Mapping Mountain Top Removal

    iLoveMountains.org is an organization that, "is the product of 14 local, state, and regional organizations across Appalachia that are working together to end mountaintop removal coal mining and create a prosperous future for the region." Together this group provides information and research to the public about the problems that mountain top removal mining has cause, and continues to cause in the Appalachians. 

    According to iLoveMountain.org, "Mountaintop removal is a relatively new type of coal mining that began in Appalachia in the 1970s as an extension of conventional strip mining techniques. Primarily, mountaintop removal is occurring in West Virginia …

  2. Mapping Shale Gas and Shale Fracturing (Fracking) Sites in the United States

    Fracking has become a hot button topic among environmentalists and politicians over the past 10 years. Shale Gas is a type of natural gas found deep within shale rock formations. In 2000 shale gas provided only 1% of U.S. natural gas production; by 2010 it was over 20% and the U.S. government's Energy Information Administration predicts that by 2035 46% of the United States' natural gas supply will come from shale gas (Wikipedia, 2013). There is significant debate about whether fracking should be increased to these levels due to the environmental risks associated with the fracking process. Opponents …

  3. Introducing Cartographica 1.4: Cluster Analysis

    Cartographica 1.4 now has the ability to perform Cluster Analysis. Cluster Analysis involves choosing and setting a number of parameters that are used to identify "hot spot" locations of point level data. Clusters are areas that have high concentrations of a particular incident. Knowing where high concentrations of certain things are located can be a very valuable tool for analysts conducting spatial analysis. 

    The two main parameters used to identify clusters are Minimum Count and Distance. Minimum Count allows you to determine how many points are needed to identify a cluster. For example, if the minimum count is set …

  4. Negative Buffering in Cartographica

    Buffers have many applications for users of GIS. A buffer is a polygon that is drawn at specified distances around a set of point, line, or polygon features. Buffers are often used to indicate the proximity of a feature to other surrounding features. For example, school officials in one community wanted to know which schools were within 500 yards of parks due to increased reports of students skipping school in those locations. 

    There are different types of buffers, but the most common method is the Uniform Width Buffer. This method identifies areas that are specific distances from a set of …

  5. Mapping Idea Tolerance in U.S. Cities

    Richard Florida is the well-known author of the book "The Creative Class" which describes the rise and the importance of a socio-economic class of individuals that Florida believes drives economic and social development. According to a Wikipedia, the creative class is made up of two separate groups of workers that make up about 30 percent of the U.S. workforce. The first of these groups is the Super-Creative Core: This group comprises about 12 percent of all U.S. jobs. It includes a wide range of occupations (e.g. science, engineering, education, computer programming, research), with arts, design, and media …

  6. Exploring Sea Level Change with Cartographica

    The Pacific Institute has recently released a set of GIS data on measures of Sea Level change on the West Coast. This is a topic that has been in the news recently as scientists are investigating changing sea levels along coasts around the world. We are always trying to point our customers to new sources of data that they can use in their own professional work, or for the purpose of exploring the world around them with publicly available data. To download the Pacific Institute data visit the GIS Data Downloads section. Notice when you go to the website there …

  7. Streamlining Workflow when Adding Features

    When creating maps that involve drawing new features such as points, lines, and polygons it is often the case that you may want to create several new features that are exactly the same. Essentially, you may want to create identical features without having to re-draw each one. Cartographica has multiple functions that allow you to perform this task. I will illustrate with an example using polygons.  

    There is a pavilion structure in downtown Lexington, Ky that is used for various events, one being its hosting of the local Farmer's Market on specific days throughout the week. In Lexington, one of …

  8. Investigating International Incidents with Cartographica

    The recent troubles in Syria have escalated a little farther when Syrian Forces shot down an American made F-4 Phantom Jet flown by Turkey. Multiple news sources are reporting on this issue and there have been some inconsistencies about what actually happened. According to an article written in the Telegraph, the Turkish Foreign Minister has stated that the F-4 was shot down in international airspace after briefly entering Syrian airspace. The attack came without warning to the pilots of the jet. Secretary of State Hillary Clinton has condemned the attack and has been quoted as saying that the attack was …
