NEW TNMCorps Mapping Challenge! Schools in ME, NH, & VT

Release Date:

It’s rapidly approaching back-to-school season with summer half way over.  To help our volunteers prepare for the transition, TNMCorps has launched a new mapping challenge for schools in Maine, New Hampshire, and Vermont.

This challenge should be relatively quick since half of the points have already been edited and are awaiting review (i.e., green) while the other half are finished (i.e., yellow).   However, in addition to confirming existing schools, volunteers should also check for missing schools.  See below for tips on searching for missing schools along with possible sources.

Tips and tricks for this challenge:    

Existing Schools  

  1. Use 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 ‘Comment’ field and delete the point.   
  3. Similarly, if you come across a school that is no longer in operation, document your findings in the ‘Comment’ field and delete the point.  
  4. If a school has moved from one building to another, do not delete the point and recreate it.  Instead, click and drag to move the existing point to the new building. 
  5. 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, review each of the schools listed on district websites and then search the web editor to see if each school has a point.    
    • Use the web editor’s search tab to search for the school by name or address. 
  2. If the school does not yet have a point, locate the correct building in aerial imagery and place a point for the school on the center of the building. 
  3. If the school does have a point, review the point’s geographic location, symbol, and attribute information against the school’s website and make any adjustments necessary.  
  4. 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. Maine’s Department of Education has a school directory that users can filter by county, city, or school type.  
  3. New Hampshire’s Department of Education provides lists of local district schools, public charter schools, and private schools on their Pathways to Education page.  
  4. Similarly, Vermont’s Agency of Education provides lists of public schools and independent (private) schools on their School Directories page.  


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.
