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 Updates - Courthouses Completed?!

6/1918 -------------------------------------------------------------

Courthouses - Finished!

It looks to us like courthouses may be finished (for now)! If you notice something missing in a state that hasn't been reviewed yet (i.e. hasn't turned yellow), make sure to add it.

THANK YOU to all of our volunteers who participated in this pilot project!!! We will be rolling out recognition badges for participation in collecting courthouses soon.


Mapping Challenge Updates - Courthouses: ALMOST FINISHED!

6/13/18 -------------------------------------------------------------

Courthouses - We're almost there!

Here is an updated status map showing the courthouse points collected to-date. We are so close to wrapping up courthouse collection. Help us finish up Arkansas, and if you're up for it, glance around and make sure all counties were collected in the states that aren't yellow yet.

If you're new to this, make sure to check out the courthouse section of our user guide for an overview of this pilot project and editing guidelines.

And be on the lookout for some recognition badges designed to specifically recognize those who've contributed to our pilot study!


Mapping Challenge Updates - SO CLOSE!

6/5/18 -------------------------------------------------------------

Georgia Post Offices

WOWZERS! Our Georgia Post Office mapping challenge is SO CLOSE to being finished! All of the points have now been edited by standard editors. What's even better is that there are only 11 points that need to be reviewed by a Peer Reviewer or Advanced Editor. As always, our volunteers never cease to amaze us!

If you're a Peer Reviewer or an Advanced Editor, help us check out these last few points.

 Please be aware of and look for these things while editing

a) Missing Post Office points

We know there are many missing points (possibly as many as 200!), including some areas that don't have any points at all, as circled in the status map below. If you are editing in GA it may be worthwhile to work systematically by city, or zip code, using the USPS Locator tool.


b) Duplicate Post Office points

Make sure you zoom all the way in, and look for any duplicate post office points. If you do find a duplicate, make sure follow these guidelines when deciding which point to delete.


c) Points on the road rather than the correct building

Because this post office data was originally geocoded, the positional accuracy is variable, and points may be located on a road near the correct building. Make sure you are finding the correct building and moving the point onto the building, which is true for editing in all situations, but is a more common issue with post office points. You may find the recent article on aerial photo interpretation for post offices in the November 2017 newsletter helpful.


As always, make sure you use the USPS Locator tool as your primary source when editing post offices and review the structures table for what we do and don't collect. In addition, you may want to check out some of our past newsletter articles highlighting post office editing, including the January 2017 newsletter (pages 4-5), and the March 2017 newsletter (pages 2-4; 7). Don't forget, the Q&A page is a terrific resource as well. You can search for questions pertaining to a specific topic using the search bar at the top:


EDITING TIP: Don't forget that you can filter points in the editor to just show the structure type you are editing.

Courthouses

Courthouses are getting so close, too!! There's now only two states left!! Hurry and get your courthouses in before they're all added! Peer Reviewers and Advanced Editors can also edit any green courthouse points.

Mapping Challenge Updates - Courthouses: Three States Left!

5/30/18 -------------------------------------------------------------

Courthouses - Only Three States Left! The Blank Spaces on the Map are Filling!

Here is an updated status map showing the courthouse points collected to-date. It's exciting to see the blank spaces on the map filling up! Only three states left now: Arkansas, Georgia, and Tennessee!

If you're new to this, make sure to check out the courthouse section of our user guide for an overview of this pilot project and editing guidelines.

And be on the lookout for some recognition badges designed to specifically recognize those who've contributed to our pilot study!


Mapping Challenge Updates

5/16/18 -------------------------------------------------------------

Here is an updated status map showing the courthouse points collected to-date. Volunteers have collected an impressive number of points, and all from scratch! There is still some work to be done to help fill in the blank spaces. Don't forget that Peer Reviewers and Advanced Editors can also check points with a green border.


Not sure where to start?? CourtReference.com is a good launching point and provides links to county websites. Our Courthouse Pilot Project Guide also provides information on the types of courthouses we are collecting.

Mapping Challenge Updates - Georgia Post Offices / Courthouses

4/26/18 -------------------------------------------------------------

Georgia Post Offices - So Close!

Don't forget about Georgia Post Offices! We're getting really close to completion with only a few points left! Use the interactive challenge map to find which point still need editing. There are a handful that also need Peer Reviewed.

Courthouse Mapping Challenge: National Status Map - Only 4 States Left!

Here is an updated status map showing the courthouse points collected to-date. As we get closer to completion, collection of courthouses has slowed. We have begun the process of reviewing the data, so you'll see that some states have started turning yellow! But fear not; there are still a handful of states that need to be done. With only 4 states left, we know our volunteers can do it! Help us get the whole country collected by filling in those blank areas.

If you're new to this, make sure to check out the courthouse section of our user guide for an overview of this pilot project and editing guidelines.

Don't forget that Peer Reviewers and Advanced Editors can also check points with a green border.

Mapping Challenge Updates - Courthouses are Turning Yellow!

4/19/18 -------------------------------------------------------------

A huge shout-out to all of our volunteers who have helped with the Pilot Study! There's still some blank spaces on the map where courthouses need collecting. Check out our Courthouse Pilot Project Guide for more on how to populate courthouses!

Mapping Challenge Updates - More Courthouses are Coming In!

3/28/18 -------------------------------------------------------------

It's always exciting to see more points being added to our courthouse status maps. Just look at West Virginia and South Carolina... A huge shout out to our volunteers for helping us collect this data!


Mapping Challenge Updates - Courthouses Continue!

3/20/18 -------------------------------------------------------------

Our courthouse mapping challenge is still ongoing! There's a few counties in Indiana that need courthouses, along with Arkansas, Kentucky, Virginia, West Virginia, Tennessee, Alabama, Georgia, and South Carolina!

If you're new to courthouses, make sure to check out the courthouse section of our user guide for an overview of this pilot project and editing guidelines. As for authoritative sources, http://www.courtreference.com/ is a good starting point along with NCSC's listing of State Court Websites.

As always, Happy Mapping!

New Courthouse Challenge: Georgia

Are you editing Post Offices in Georgia for the mapping challenge? Why not add courthouses as you work your way through the state? Before participating in courthouse collection, make sure you've read the courthouse section of the user guide.

(Non-Courthouse) Challenge Update: Georgia Post Offices

Wow! The GA post office challenge is coming along nicely. As usual our volunteers have risen to the challenge. As a reminder, there are some issues with the post office data in Georgia, so please make sure you've read the additional info below before participating in this challenge.


 Please be aware of and look for these things while editing:

a) Missing Post Office points

We know there are many missing points (possibly as many as 200!), including some areas that don't have any points at all, as circled in the status map below. If you are editing in GA it may be worthwhile to work systematically by city, or zip code, using the USPS Locator tool.

c) Points on the road rather than the correct building

Because this post office data was originally geocoded, the positional accuracy is variable, and points may be located on a road near the correct building. Make sure you are finding the correct building and moving the point onto the building, which is true for editing in all situations, but is a more common issue with post office points.

Mapping Challenge Updates

2/15/18 -------------------------------------------------------------

Georgia Post Offices - "Georgia On My Mind"

A reminder that we have a new mapping challenge out! This time it's post offices in Georgia! This map challenge can be a bit of a challenge (ha! pun intended!) because Georgia is missing several post offices, there are duplicate existing points, and several existing points also need to be moved from the road to the correct building. Nothing that our volunteers can't conquer!

Georgia Post Offices - New Interactive Web Map

To help our volunteers with the new map challenge, we've also developed a new Interactive Challenge Map! Click here (or on the image below) to explore Georgia Post Offices!

Courthouse Mapping Challenge: National Status Map

Our Courthouse Pilot Project continues with several states in the east yet to have their county courthouses mapped!


Mapping Challenge Updates - Georgia On My Mind

Courthouse Mapping Challenge: National Status Map

Here is an updated status map showing the courthouse points collected to-date. Volunteers have collected an impressive number of points in just a few short months. There is still some work to be done though, so if you're interested in editing courthouses, help us finish up the remaining few states. Don't forget that Peer Reviewers and Advanced Editors can also check points with a green border.


New Courthouse Challenge: Georgia

Since courthouse editing has slowed slightly in the last week, we are going to run another state challenge. Georgia is looking lonely without any courthouse points, so that will be our new courthouse mapping challenge.


New (Non-Courthouse) Challenge: Georgia Post Offices

If you're not collecting courthouses, we have a new non-courthouse challenge you may be interested in: Georgia post offices. This challenge will be unique and perhaps a little more challenging than usual. We know there are issues with the data, so volunteers will have to be extra diligent while editing.

Please be aware of and look for these things while editing:


a) Missing Post Office points

We know there are many missing points (possibly as many as 200!), including some areas that don't have any points at all, as circled in the status map below. If you are editing in GA it may be worthwhile to work systematically by city, or zip code, using the USPS Locator tool.
