New to The National Map Corps? Head over here for an overview of the project.

Mapping Challenges will be released periodically and are a way to focus volunteers on areas that need editing. The challenge is to edit the red points if you are Standard Editor and to Peer Review the green points within the challenge area released. Make sure to look for missing points too! Advanced Editors can edit any of the points within the challenge area. 

Volunteers who contribute in the Challenge area will be recognized on this page and also tweeted on The National Map Twitter account. Contribute to The National Map by participating in Mapping Challenges!

Mapping Challenge Update: Schools in Wayne County, MI

Edits are coming along smoothly for schools in Wayne County, MI!  Obsolete schools are being removed while existing schools are being updated, which is exactly what we anticipated. Just a reminder to confirm changes with an authoritative source before adding, updating, or removing a point.

Reach out to us at nationalmapcorps@usgs.gov with questions.  Thanks for all you do, and happy mapping!

Mapping Challenge Update: City / Town Hall Structures in New Jersey, New York and Pennsylvania

It's always fun seeing the points that come in week by week for our challenges!  Part of it is because it demonstrates just how awesome our volunteers are!  There's still a few incorporations in Upstate New York to be collected, especially in Albany, Fulton, Herkimer, and Montgomery counties among others.    

There's also several green points throughout the area that need to be checked by a Peer Reviewer or Advanced Editor.  Our Interactive Web Map can help locate these points.

NEW Lightning Challenge: Back to School in Wayne County, Michigan!

9/05/19 -------------------------------------------------------------

New Mapping Challenge!  A Lightning Challenge for Schools in Wayne County, Michigan

With our current lightning challenge now complete, we wanted to launch another challenge just in time for back-to-school!  What better time to focus on TMNCorps’s school features?  

What is a Lightning Challenge?

For those who are new to our mapping challenges, a lightning challenge is just like our other mapping challenges except they have smaller project areas and shorter time frames.  

Schools in Wayne County, Michigan

This lightning challenge will focus on General Schools, Elementary Schools, Middle Schools, and High Schools in Wayne County, Michigan (i.e., the Detroit area) and will run for the month of September.   

As you can see from the status map, there are many features in the area that have yet to be edited.

Due to the age and source of the schools data in this area, we're anticipating many changes which may include (but are not limited to):

Anticipated Changes

Tips and Tricks

  1. Positioning the school on the correct building

Check out this page of the User Guide for how to move a point

  1. Confirming that schools are still open (or adding new schools)

Check out the User Guide for how to research a feature. Pages on adding or removing a point may also be helpful 

  1. Making sure the school’s name matches the school website 

Use an authoritative source when updating names

  1. Removing special characters (e.g., commas, periods, etc.) from the Name field

See our Name and Address Formatting Guide for more information on special characters

  1. Checking to ensure the school’s icon is correct 

Check our our Structures List and this Decision Tree for more on school symbols

  1. Converting ALL CAPS to Title Case 

See our Name and Address Formatting Guide

  1. Removing the 4-digit extension from zip codes

Check out this article titled Ditch the Digits: New Zipcode Guidelines in our November 2018 Newsletter

For starters, Wayne County Regional Educational Service Agency (RESA) provides a list of all the public school districts in Wayne County, MI.  Be sure to visit each district’s website for a list of public schools (and corresponding school websites) within. As for private schools, good starting points include MetroParent and NCES. Note that these are secondary (aggregate) sources and do not include every private school in Wayne County.  

Regardless of whether it is public or private, remember to confirm each school with an authoritative source (i.e., a school website) before editing a point. 

What about the other mapping challenges?  Are they still open?

Our mapping challenge for Colorado is closed, but our challenge for the Mid-Atlantic (i.e., NY, NJ and PA) is still open as of this post.  Feel free to participate in either challenge, and check back frequently for updates on each.

Mapping Challenge Update: City / Town Hall Structures in New Jersey, New York and Pennsylvania

Points are steadily coming in with another 200 points added since last week.  Great job!  There's still a few incorporations in Upstate New York to be collected.  New York's website has a very nice list of all the counties in the state.  It also lists the municipalities found in each county, so a helpful resource indeed. 

There's several green points throughout the area that need to be checked by a Peer Reviewer or Advanced Editor.  Our Interactive Web Map can help locate these points.

Mapping Challenge Update: City / Town Hall Structures in CO

Mapping Challenge Update:  Lightning Challenge for City / Town Hall Structures in Colorado 

Colorado is SO CLOSE!  Thank you to everyone who has contributed so far!

We've included two separate status update maps again.  We also performed the same quick analysis, but this time for the entire state.  Most of the Denver suburbs have now been collected; there's still a handful in the metro area that need collecting along with some other communities scattered throughout the state.

A reminder that this is not a definitive list of what remains to be collected; it only shows the relationship between incorporated places (i.e., polygons) and city / town halls (i.e., points). Edgewater is a perfect example of a community whose City / Town Hall has already been collected but was highlighted by this quick analysis because its city hall falls just outside of its polygon.  Alas, the labeled communities on this second map are a rough checklist of what remains to be collected in Colorado.

Check out the article titled Ensuring Data Completeness in our July 2019 newsletter for authoritative sources.  Still not sure which communities should be collected?  Be on the lookout for an article in our September Newsletter providing tips on the different types of communities along with those that are more likely to have a City / Town Hall.

Mapping Challenge Update: City / Town Hall Structures in CO

8/22/19 -------------------------------------------------------------

Mapping Challenge Update:  Lightning Challenge for City / Town Hall Structures in Colorado 

Colorado is nearing completion, though there's still a few features that remain to be collected.  Here is an update map that includes incorporated places (small, gray polygons). 

We also performed a quick analysis to see which Denver suburbs have a point within their corporate limits (light gray) vs. those that do not (dark gray with labels); see the second map below for results.  Note that this is not a definitive list of what remains to be collected; it only shows the relationship between incorporated places (i.e., polygons) and city / town halls (i.e., points).  In other words, it's possible that some of these dark gray jurisdictions have already had their City / Town Hall collected but it does not fall inside the gray polygon.  It's also possible that some don't have a designated City / Town Hall building at all, and that's ok, too! The intent is to serve as a checklist of possible remaining features in the Denver Metro Area.

NEW Mapping Challenge! City / Town Hall Structures in CO

8/9/19 -------------------------------------------------------------

New Mapping Challenge!  A Lightning Challenge for City / Town Hall Structures in Colorado 

Our current challenge in the Mid-Atlantic is nearly complete so we wanted to spice things up a bit with a Lightning Challenge!  

What is a Lightning Challenge?  

A Lightning Challenge is like our other mapping challenges except it has a smaller project area and shorter time frame.  

City / Town Hall Structures in Colorado

This challenge will focus on City / Town Hall structures in Colorado and will run through mid-September.  Approximately 200 points still need to be collected. USGS will be updating Colorado US Topo maps soon so what better time to offer a Lightning Challenge for this area!   

City / Town Hall structures in Colorado will primarily be found in cities and towns. Try looking at the smaller towns along the highways and roads for missing points.  Here is a Wikipedia article further describing Colorado’s governmental structure. Colorado’s Department of Local Affairs also offers census data by city / town, which may also be of assistance. 

There isn’t much existing city/town hall data, so many points will need to be added as new features. Check out this article titled Ensuring Data Completeness from our July 2019 newsletter for tips on how to collect a complete dataset from scratch. 

We’re also working on the interactive web map for this challenge as we speak, so check back often!

What about the Mid-Atlantic City / Town Halls Challenge? 

Our mapping challenge for NY, NJ, and PA is still open as of this post, so feel free to participate in either challenge!

Mapping Challenge Update: City / Town Hall Structures in New Jersey, New York and Pennsylvania

Here's the current status of our mapping challenge.  All of the major cities are filling in, leaving some of the more trickier townships yet to be collected.  When deciding whether to collect a township or borough, a general rule of thumb to follow is this: if the jurisdiction (e.g., municipality, township, village, or borough) uses any level of self-governing authority to provide governmental services to its residents, then these services are often administered from a common building.  If a building is used solely for these purposes, then it would be considered a City / Town Hall.  

Here's a few Wikipedia articles that better describe the governmental structure of each state: 

Be on the lookout for articles in our next few newsletters discussing this very topic as well.  Reach out to us at nationalmapcorps@usgs.gov with questionsThanks for all that you do, and Happy Mapping!

Since our last update, it looks as though all of the seed data (i.e., red points) have been edited and confirmed!  Keep up the good work!

There's still plenty more to edit before this challenge is complete.  Remember that most of the points for this challenge will be added directly by volunteers.  And as you can see from the western portions of New York and Pennsylvania, there's plenty of City / Town Halls throughout these states due to their relatively long history with communities dating back to the colonial period.

NEW Mapping Challenge!

NEW Mapping Challenge! City / Town Hall Structures in New Jersey, New York and Pennsylvania

Since our volunteers are (star) amazing (star) and did such an awesome job collecting City / Town Hall structures in the DC area, we wanted to extend this effort up the eastern seaboard. This puts our next challenge focusing on City / Town Hall structures in New Jersey, New York, and Pennsylvania.

These states contain a large amount of historic architecture (especially NY and PA...), so check out our newsletters from July, September, and November 2018 for more on the different types of architecture one might encounter.

The tips and tricks for this challenge are similar to the DC Area, yet are worth mentioning again with a few updates (highlighted in italics):  

Incorporated Places

  1. Most of the City / Town Hall structures will fall within incorporated places. An incorporated place is an area that is governed by a local municipal corporation.
    1. Incorporated places in NJ, NY and PA may include cities, towns, or villages.
  2. There may be multiple City / Town Hall structures in each county.
  3. A good place to start is to search Wikipedia for a list of municipalities or incorporated places in each county. 
    1. Remember that these Wikipedia lists are only a starting point and are not an authoritative source.
    2. Therefore, as you work through the list to map each entry, be sure to confirm each feature with an authoritative source such as the city’s website.

Proper Point Placement

  1. There’s slightly more seed data (i.e., red, unedited points) for this challenge compared to the last, however most of the features for this challenge will still be collected from scratch.  
  2. Different incorporated places may share a building for their city/town hall locations. If so, add a point for each city/town hall. An example of this is the Rye Town Office which occupies space on the Third Floor of the Port Chester Village Hall in Port Chester, NY.
  3. Our November 2018 newsletter includes an article on aerial interpretation for City / Town hall structures. This article walks readers through how to find the correct building to place a point on when examining aerial photography.

We’re working on the Interactive Web Map for this challenge as we speak. We’ll post it on this page once it’s available, so stay tuned!

If you have any questions during the mapping process, reach out to us at nationalmapcorps@usgs.gov and someone will be happy to assist!  Thank you for all that you do, and happy mapping!
