Citizen Scientists Cited
The National Map Corps (TNM Corps) is an online crowdsourcing mapping project with volunteers successfully editing structures in all 50 States, Puerto Rico, and the U.S. Virgin Islands. As part of The National Map, structures include schools, hospitals, post offices, police stations, cemeteries, and other important public buildings.
By updating and verifying structures data, volunteers are making significant contributions to USGS National Structures Database, The National Map, and ultimately U.S. Topo Maps. The submitted and approved points from these participants have resulted in updated and enhanced mapping information as well as saving significant taxpayer dollars and man hours.
To reward these novice cartographers, TNM Corps developed a “recognition program” of virtual badges that can be earned as a volunteer reaches certain submission levels. There have been a little more than a dozen committed volunteers who have reached the top award level, submitting more than 6,000 points along with spending time as a senior reviewer and assisting other participants.
Another of our intrepid citizen cartographers is “meyerkv”. As a long time TNM Corps participant, he has well surpassed the top recognition level and earned the “International Year of Mapping Badge” in a relatively short amount of time. In addition, “meyerkv” has made it a personal mission to systematically work through the structures data in Puerto Rico. So how did he become a very active contributor to improving America’s structure data? His story:
“I’ve always loved maps, aerial imagery, and cartography. In this age of GPS devices, I still believe much can be learned from examining maps. So, I was attracted to The National Map Corps and the ability to volunteer from home.”
“I worked county-by-county as I went through the Mid-Atlantic states, using available databases, and doing a little research on each jurisdiction before editing structures in the county. Since I grew up here and spent most of my life in Virginia and visiting nearby states, I figured it would be a good match to update areas where I had some familiarity with.”
“Another reason for volunteering for theTNM Corps was I wanted to support the Federal government. I worked for several Federal agencies for 34 years before retiring. I started my Federal career working with aerial imagery in the late 1970s while employed by the U.S. Department of Agriculture full time and going to school full time at George Mason University.”
“We used aerial imagery for random sampling of land areas in each of the 50 states for crop surveys. A secondary issue for the USDA in these surveys was to identify resources in rural areas such as fire departments, colleges, schools, police stations, hospitals, cemeteries, etc, available for farmers. We tried to identify these resources with the resources available aerial imagery, topographic maps and phone books.”
“So working with The National Map Corps has been a pleasant flashback to my college days. One of my favorite maps is the historic 1915 USGS 15’ topographic map, Fairfax. This map covers the area near my parents home and it is also halfway in time between the end of the Civil War (another favorite subject) and when we moved to Chantilly in 1965. Many of the roads and structures depicted in Civil War maps and sketches can still be found on the 1915 Fairfax map and several still existed in 1965. It has been fun and educational editing the National Map. Thanks for the opportunity.”
