Some would say that maps had a profound impact on the shaping of our world; until explorers and wayward travelers began documenting their travels, few were able (or willing) to follow in their footsteps. The precise maps we are accustomed to today require a great deal of skill to produce -- they're a far cry from the incomplete or malproportioned maps of centuries past. The precision used to craft reliable maps is a skill that cartographers and photogrammetrists hone through extensive training and education.

According to the U.S. Bureau of Labor Statistics (bls.gov), cartographers and photogrammetrists analyze and interpret geographical information to build maps that are used for cultural, political and educational purposes. The world is always in flux, and as it becomes more developed, we'll rely on a growing number of mapmakers to keep us from, literally, losing our way.

A whole new world: career outlook for cartographers and photogrammetrists

The future is bright for tomorrow's mapmakers. According to bls.gov, demand for cartographers and photogrammetrists is expected to grow 22 percent between 2010 and 2020. Most of this growth will be driven by increased use of maps for national security and government planning purposes, but also from a growing demand for maps that incorporate information gathered online and through social media. Retiring baby boomers will also open new doors for future cartography and photogrammetry schools graduates.

Though demand for cartographers and photogrammetrists is strong on a national level, some states have more promising career prospects than others. According to the U.S. Department of Labor, the following states are projected to see the largest boost in demand for these professionals between 2008 and 2018:

• Virginia: 37 percent projected growth
• Utah: 33 percent projected growth
• Indiana: 31 percent projected growth

Cartographer and photogrammetrist salary information

Cartographers' and photogrammetrists' earnings vary tremendously from one position to the next. According to bls.gov, the median cartographer and photogrammetrists salary in 2011 was $55,970, though the top 10 percent earned in excess of $92,310. The federal government was the highest paying employer, offering a median salary of $82,570; technical services were a close second, paying $80,040 on average.

It is important to note that other factors -- such as your education or work experience -- can influence your earnings. Location is another important variable. For example, bls.gov notes that the following were among the most lucrative states for cartographers and photogrammetrists in 2011:

• Florida: $76,220
• Nevada: $72,180
• Washington: $71410

Mapping your future: how to become a cartographer or photogrammetrists

The world of mapmaking has come a long way since 16,500 BCE, when artists in the Lascaux caves, in what is now France, mapped out portions of the night sky. Today's cartographers or photogrammetrists need a healthy dose of math, science and geography instruction. Because it is such a skilled trade, bls.gov notes that a bachelor's degree or greater in cartography or a related field is a must to excel in this career. Cartography and photogrammetry degree programs provide this type of specific education. Many schools even allow students to complete part or all of their cartographer and photogrammetrists training online -- an excellent option for those already working in the field who want to advance their educations.
