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 …

Georeferencing Detailed Cold War Era Maps using Cartographica

According to a recent article on Burrito Justice, during the Cold War the Russian government spent a lot of time and effort to create detailed maps of the many places in the world as potential targets for their military.
