Important State Information

Alaska and Hawaii Imagery Issues

We are working to obtain higher resolution imagery for Alaska.  Because we are using alternate imagery for both Alaska and Hawaii we have encountered a few interoperability issues.  When in the viewer tab, if you do not see any imagery when clicking on Aerial Imagery [click on the background drop down menu in the upper right hand corner of the viewer] use the pan tool or zoom in or out. The imagery should now appear. If you continue to have problems, please email us at: nationalmapcorps@usgs.gov

Puerto Rico

Editing in Puerto Rico has some interesting (and fun!) challenges. Please take a look at this tips and tricks guide if you are interested in contributing data in Puerto Rico. 

Also, the imagery quality is much better zoomed in, so make sure you zoom in to edit!

 

We have found an issue with the Classic Topos background layer over Puerto Rico. At this time please do not use this layer while editing in Puerto Rico.

Editor Questions

Q: What do the colors around the icons mean?

A:  Red: Unedited - Needs to be confirmed or corrected by a volunteer through the Standard Editor. Advanced Volunteers may use the Advanced Editor.

    Green: Edited - Point has been confirmed or corrected by a volunteer using the Standard Editor.

    Blue: Peer Reviewed - Point has been peer reviewed by a volunteer using the Peer Review Editor.

    Purple: Advanced - Point has been corrected or confirmed by an Advanced Editor.

    Yellow: USGS Reviewed - Point has been reviewed by the USGS.

Q: Why would I give The National Map Corps my Twitter handle? 

A: When you sign up for The National Map Corps you can give us permission to Tweet your TNMCorps username through The National Map Twitter account as part of our volunteer recognition program. If you have a Twitter account and would like us to @mention you in the recognition tweet, simply enter your Twitter handle when you sign up. If you already have an account and would like to add your Twitter handle to your TNMCorps account, click on your username in the top right corner, go to "My Settings" and then enter it under "Current Twitter Handle." 

Q: What is the AK Community Photos background layer?

A: AK Community Photos are high quality aerial photos over some villages and communities in Alaska. This layer will only appear in the background layer dropdown when you zoom to Alaska. The imagery is provided by the Alaska Department of Commerce, Community and Economic Development, Division of Community and Regional Affairs Community Profile Projects. They are easier to find by zooming to a specific place, for instance "Wales, AK."

Editing Questions

Q: I found a bunch of points stacked on top of each other and they are all post office points. What should I do with them? 

A: This is a problem you may see that comes from some of the legacy data we use. If the points are for different post offices, verify that they still exist and then move them to the correct location. You should move the existing point rather than creating a new one in the correct location. If the points are all the same, verify that the feature still exists and then delete all but one of the points.

Q: I found a building that is a fire station and a police department. Do I add a point for each one?

A: You should add a point for each unique function of the building only if the separate functions are also separate entities.  For example, if a fire station also has EMS (Emergency Medical Services) capabilities you would not add separate points for the fire station and EMS;  however, if the EMS company was different from the fire company you would add two separate points on the building.  In other words, there should only be one point per entity, even if that entity serves multiple functions.

Q: I added a point for a structure that I didn't think had an existing point, but then I found one later. What should I do?

A: In this situation, go ahead and keep the point you added and delete the existing unedited point you found later. 

Q: I found a nursing home. Should I code this as a “Hospital"?

A: If you are unsure whether or not a particular type of feature should be collected, please check the structures list for definitions and examples of what we want and do not want collected. If you are still unsure, email us at nationalmapcorps@usgs.gov. 

Q: What is the correct naming convention for Post Offices?

A: Post Offices should be given the name found on the USPS locator tool + "Post Office." In the examples seen below, the correct name for the first example is "Denver Post Office." If you find a post office with an additional name in parentheses, as seen in the second example, please format it like, "Westminster Post Office Harris Park Station." For more information on editing Post Offices, please see the Post Office example in the Peer Review User Guide.

Q: What if an authoritative website cannot be found for a feature? Is the next option driving by the Google address to confirm its address/existence?

 A: You can definitely “drive by” using Google™, street view but never use the address provided by Google. Addresses and even locations are frequently inaccurate in Google maps.  If you cannot find an authoritative website, try to locate a number using the Yellow pages or another source, and call the feature to verify the attributes and location.

Q: The medical center, located at 8451 Pearl Street, has numerous different clinics and hospitals located there, but all seem to fall under Vibra Hospital of Denver. Should the other clinics be deleted from the map and replaced with Vibra Hospital of Denver?

A: Are the clinics existing points?  Does the hospital have an existing point?  Because we are only collecting Hospital/Medical Centers for this project and not our other medical related features types, you should only keep/collect a point for the hospital.  If there are existing points, delete all but the hospital.  If there are not existing points and you just found the website listing all of the different facilities, please only add a point for the hospital.   Also, please make sure to use the official hospital name from the website.

Q: The point I am researching contains the 4-digit suffix on the zip code, should I keep this or delete it?

A: The 4-digit suffix on a zip code is not required. You can use the USPS zip code search engine by inputting the official address to find the full zip code. If you are unable to verify the last 4-digits it is acceptable to remove them from the zip code.

Miscellaneous Questions

Q: Can I count my volunteer hours toward community service or to fulfill my scholarship?

A: Currently we have no way of tracking the hours that you work on The National Map Corps. You can, however, contact your reporting agency and check to see if they will include the time you spent on the project. If they approve, keep track of your hours and send them to us for verification. We will compare the hours you have claimed to the number of edits you have made and see if it appears to be reasonable. Be sure to track and include the time it takes to read the User Guides and the time you spend researching points.

Q: Do my updates also help update OpenStreetMap (OSM)?

A: Not at this time. We are working on a procedure to pass along updates from our volunteers to OpenStreetMap.
