NEW TNMCorps Mapping Challenge for Schools in GA & SC!

Release Date:

As we continue to prepare states for US Topo map production, we have another challenge for schools in Georgia and South Carolina!  Features participating in this challenge include General Schools, Elementary Schools, Middle Schools, and High Schools.   

There is ample seed data for this challenge with many points needing review (i.e., green).  However, in addition to confirming existing schools, volunteers should also check for missing schools.

Not sure what each point color represents?   

TNMCorps uses a tiered editing process.  A point's border color represents which tier the point has passed through:

See the article titled Editor Roles and Point Colors in our November 2018 newsletter for more information on the tiered editing process and what each color means.   


Tips and tricks for this challenge:  

Existing Schools  

  1. Volunteers can locate existing schools by using the dropdown filters on the web editor’s edit tab to filter by feature type and edit status.   
  2. Remember we are not collecting preschools or childcare facilities.  If you come across an existing point for a childcare or preschool, please document your findings in the ‘Comments’ field and delete the point.   
  3. Similarly, if you come across a school that is no longer in operation, document your findings in the ‘Comments’ field and delete the point.  
    • NOTE: if a school has moved from one building to another, do not delete the point and recreate it on the new building.  Instead, click and drag to move the existing point to the new building. 
    • Similarly, if a school is no longer in operation (i.e., it has not relocated) but a new school has opened in the same building, do not delete the point.  Instead, update the name, symbol, and attribute information of the existing point to match the new school.   


Missing Schools 

  1. To search for missing schools, volunteers should review each of the schools listed on district websites and then search the web editor to see if each school has a point.    
  2. To determine if a school is already represented, volunteers can use the web editor’s search tab to search for the school by name or address. 
    • If a point does not yet exist for the school, locate the correct building in aerial imagery and place a point for the school on the center of the building. 
    • If a point does already exist, review the point’s geographic location, symbol, and attribute information against the school’s website and make any adjustments necessary.  
    • Be sure and check nearby points for duplicates as well. 


School Symbols 

  1. Not sure which symbol a school should receive?  Check out our Structures List, our Tips and Tricks, or this decision tree for guidance.  
  2. Our expanded Structures Definitions also provide further insight into what each school represents.  


Possible Sources 

  1. Remember to find an authoritative source (e.g., a school or district website) for each feature.   
  2. The Georgia Department of Education maintains a list of school districts and corresponding websites.   
  3. Similarly, the South Carolina Department of Education maintains a list of school districts and corresponding websites.  


Proper Point Placement 

  1. Our March 2019 newsletter includes an article on aerial interpretation for school structures. This article walks you through the process of using aerial imagery to find the correct building on which to place a point.
