GOOD NEWS! You are NOT required to log into this site.

To edit structures, log into the editor.

 

 

 

The mapping crowd-sourcing program, known as The National Map Corps ( TNM Corps), encourages citizens to collect structures data by adding new features, removing obsolete points, and correcting existing data for The National Map database.

 

If you have access to the Internet and are willing to dedicate some time editing map data we hope you will consider participating!

 

Volunteers can now contribute data for all 50 states, Puerto Rico, and the US Virgin Islands! You do not need to live in available states to participate. Our editing guidelines explain how you can contribute data from anywhere.

WHAT WOULD I BE DOING IF I PARTICIPATE?

 

You would be using our online map editor to edit USGS structures data by updating existing features, adding new features, and removing obsolete features. You can choose what types of structure features to edit (from our list of structures ) and edit in any of the available states shown above!

 

HOW DO I GET INVOLVED?

 

1)      Read through the editing guidelines to learn more about the project and how to contribute.

 

2)      Create an account to access the online map editor .

 

3)     Follow the directions on how to edit and add points to get started.

UPDATE: Tennessee Law Enforcement Facilities Mapping Challenge

This is one of the bigger challenges we have done, but thanks to you all, over 100 Law Enforcement Facility points have already been updated! As you can see on the map below, this includes some peer reviewed and advanced edited points, which means those are ready to go into The National Map!

However, there are still 261 existing unedited points that need to be checked before this challenge will be complete.

Please help us reach the goal of having all Law Enforcement Facilities in Tennessee updated by editing the red points seen below. If you are a Peer Reviewer please check the green points that have already been edited by another volunteer.

As always, volunteers who participate in the mapping challenge will be recognized on this page and also tweeted on The National Map Twitter account. Thank you for your contributions!

New Mapping Challenge - Tennessee Law Enforcement Facilities! / TN Prisons Challenge Finished!

New Challenge:

Way to go mapping all of the Prison/Correctional Facilities in Tennessee! We went from zero points for that feature type in TN to sixteen, and not only were they all added and edited, they were also all peer reviewed and some advanced edited, so they are all ready to go into the National Structures Dataset and The National Map! Thanks to HGeisler, Cartograsaurus, and ThatJenn

Tennessee US Topo maps are scheduled to be updated soon, so for the new challenge we are sticking with Tennessee. This time we would like you to help us edit all Law Enforcement points in Tennessee. This includes verifying or updating the existing points, adding missing points, and removing obsolete points. Although a few have been edited, there are 364 existing Law Enforcement points in TN (see map above), so this is a big challenge. Let's get these points updated before the US Topo maps for the state are updated!

Also, don't forget that you can participate in mapping challenges as a standard editor, a peer reviewer (once the points have been edited), or an advanced editor. As always, make sure you're familiar with what we are collecting for Law Enforcement before participating.

Volunteers who contribute in the challenge area will be recognized on this page and also tweeted on The National Map Twitter account (with permission).

Good luck and happy mapping!

New Mapping Challenge - Tennessee Prisons/Correctional Facilities!

The new mapping challenge covers a bigger area than any other we've done and is also quite a bit different. This time around we are asking you to map all prison/correctional facility structures in the entire state of Tennessee.

HOWEVER, there are no existing prison/correctional facility points in Tennessee, so you'll be adding all new points. This might make things a bit easier, because you can find an authoritative source and just go through and add each feature as a new point. Make sure to check for an existing point though, in case another volunteer has already added it. Also, make sure you are familiar with what we are/are not collecting for this structure type before beginning.

We recommend using these sites as authoritative resources: 

Federal Bureau of Prisons

Tennessee Department of Corrections 

Happy Mapping!

OK Panhandle Post Office Mapping Challenge Finished!

Thanks to HGeisler and fconley for correctly locating all of the improperly located Post Offices and deleting the ones that no longer exist. Way to go!!! Thank you for participating and doing such a great job cleaning up the Post Office points in the Oklahoma Panhandle counties!

New Mapping Challenge - Oklahoma Panhandle Post Offices

The new mapping challenge is similar to the previous one. Fixing stacked Post Office points in Texas County, Oklahoma through a mapping challenge was so successful that we want volunteers to fix the rest of the Post Offices in the Oklahoma Panhandle counties. Since Texas County is finished, the two remaining Panhandle Counties that need to be edited are Cimarron and Beaver Counties. 

In case you didn't participate in the last stacked Post Office Mapping Challenge, here is some background information:

The unedited (red) points in the editor come from several different data sources. Some of the Post Office points do not have exact geographic coordinates, but rather just information about which county they are in. In this situation, all of the Post Office points are stacked on top of each other in roughly the center of the county.

The goal is to check each of these points, and if they still exist, move them to the correct location. Same rules apply: delete the point if the Post Office no longer exists and update attribute information (name, address, city, state, zip) as needed. Also, don't forget to look for any Post Offices missing from the map.

The map above shows the existing Post Offices in Cimarron County and Beaver County, Oklahoma. There is one Post Office in Beaver County that isn't stacked, so don't forget to edit that one too. The names of the existing Post Offices on the map can be seen below (Blue highlighted are in Cimarron County, all others are in Beaver County.) Make sure you've read the guidelines on formatting Post Office names before participating in this challenge. As always, the USPS locator tool should be used to research Post Offices.

IMPORTANT: Please move the existing stacked points to the correct location rather than adding a new point in the correct location.

Happy Mapping!
