Why should this be important? There are many industries and agencies that rely on the data provided from satellite maps including surveyors, engineers, scientists, and even animal experts. They deliver access to the “big picture” and provide up to date information about uninhabited or significant areas.

Consider the need for highly accurate satellite maps in areas where military activity occurs. These maps must have comprehensive information about distance, elevation, landscapes, and common roads and trails. This is the sort of data that comes strictly from satellite maps and with only limited field information.

How are satellite maps and photos used to create three dimensional images? Well, there is a technology known as GIS which is used by the world’s most well-known mapmakers. It translates to “geographic information system” and while that sounds very simple, the capabilities of the technology are amazing. When it is added to a mapping program, it can take such data sets as numerous satellite maps, tons of field measurements and data, and other sources of information, and then assess and analyze these materials to create a visual solution to the issue.

For instance, the earliest use of the GIS approach occurred in 1854 when a cholera outbreak in London, England was mapped out with various data sets. This allowed the scientists to locate the very well in which the outbreak occurred. From that point onward, GIS technologies have expanded and been linked to all kinds of mapping software.

With the widespread availability of satellite maps, it is easier than ever for GIS mapping programs to create highly usable and pinpoint accurate maps of almost any area or model.
