What is a school?
Where can I find authoritative lists of schools?
There are three types of schools: public, charter, and private. Public schools and charter schools are regulated by State Departments of Education, and for this reason there usually are good authoritative lists of these schools on the State Department of Education websites. States are divided up into School Districts, many of which have web pages which are the most authoritative place to look for information.
Private schools are more difficult to sort out because there are no authoritative lists, and they tend to open and close more often than public schools. Here are some non-authoritative places you can look for private school information:
- State Department of Education websites: these may have lists of private schools, but in general they are non-authoritative because they may only include non-public schools whose school administrators have requested to be on the list.
- The National Center for Education Statistics maintains a database of private schools. This database is a result of a voluntary survey that they send out every two years. Their website allows a search for private schools by city, county, or state.
- The Great Schools website has an online searchable database.
- The National Association of Independent Schools has an online searchable database.
- The National Parochial Schools Association lists parochial schools by State.
- Look on the Data Sources page on this website for your State to see if there are any regional or local sources of private school information
Why does the Structures database contain so many schools that no longer exist?
One original source of information for the Structures database was US Geological Survey topographic maps which were produced from about 1879 to 1992. These maps showed many of the old pioneer schools that were established as a result of the Land Ordinance of 1785. This Act of Congress caused much of the 30 western States to be surveyed and divided into townships six-miles square; in turn each township was divided into 36 numbered square-mile sections, and section No. 16 of each township was to be reserved for a schoolhouse. And many of the resulting one-room schoolhouses still existed and were mapped when the older USGS topo maps were produced.
How do I handle schools with many grades?
Many schools, especially rural schools, have K-12 classes all in one building. Should these be depicted as one school, or multiple schools (elementary school, middle school, high school)? This generally is decided based on information at the school website, or, if there is no school website, then at the State Department of Education website. If these websites list separate schools at the same address, then add one structure for each school, which each structure symbol contained within the footprint of the building.
What is a College/University?
The Guidelines definition of College/University is quite specific, and the key factor is that an institution must grant a degree; there are 4 types of degrees: Associate, Bachelor, Master, and Doctoral.
Degree-granting generally is regulated by the States, and so each State has a Higher Education Agency which oversees degree-granting institutions. The US Department of Education has a list of these State Higher Education Agencies. These agencies often maintain lists of the degree-granting institutions in their State (refer to the Data Sources pages on this website for each State to find out where to find these lists).
For the most part, this degree-granting requirement leaves out vocational schools (also called trade schools, career schools, or technical schools), which generally grant certificates but not degrees. An exception is technical colleges which do grant degrees.
A separate issue is accreditation. There are many accreditation organizations which generally are private professional organizations. Each State Higher Education Agency may determine which accreditation organizations have recognized authority within that State. Usually an institution may not grant a degree unless it has been accredited; however there are exceptions to this rule – some States allow religious colleges to grant degrees even if they are not accredited. Conversely, there may be schools that are accredited but do not give out degrees (only certificates).A second, less obvious stipulation in the definition of College/University, is that there be a building used as an institution of higher learning. This leaves out online universities, unless they teach classes in their buildings as well as online.
Where do I place a College/University structure point?
In general, each college/university campus should be represented by a single structure point placed on the administrative building for that college/university. If one does not have firsthand knowledge of the location of the administration building, it can usually be gleaned from a brief examination of the school's web page. If it cannot be determined where the administration building is located, then place the structure point on a building at the center of the main cluster of buildings on the campus.
A University campus may contain several colleges or schools (ie College of Arts, College of Sciences, School of Business, School of Medicine), but so long as these are units of the same University and located on the same campus, then they should be represented by a single point. However in some cases, separate institutions may share the same campus (for example, the Auraria campus in Denver, Colorado is home to Metropolitan State University of Denver, the University of Colorado at Denver, and the Community College of Denver) – in this case each separate institution should be represented by a point.
Some Colleges, especially in an urban environment, may have multiple campuses or widely dispersed buildings. This is somewhat of a grey area, but in general a separate campus should be represented by its own structure point. However, if a dispersed college location consists of a single building, or a few rooms in a single building, then you will have to use your own judgment as to whether it is important enough to be considered a campus and therefore justify a new structure point.
Medical Schools that are co-located with Hospitals should be represented by a college/university structure point only if the medical school is large enough to have at least one building separate from the Hospital; if so, the associated Hospital would also be represented as a Hospital structure type.
Where can I find authoritative lists of Fire Stations?
Try to find out the official name of the station; it often has the format: <fire-department-name> <station-name>. For example "Denver Fire Department Station 1". Official station names sometimes have either a "-" or a "/" in the station name, and while the Attribute Guidelines say that special characters should be avoided, they can be used if necessary to document an official fire station name.
It seems surprising that there are no authoritative lists of fire/EMS stations, but this is because historically it has been felt that it is more important that they can find you, rather than for you to find them. They can find you through the 911 system. The 911 system generally is maintained at the county level, where 911 calls are routed to the nearest Public Safety Answering Point (PSAP). While you are talking to a 911 operator at a PSAP, various manual and automated systems are used to pinpoint the location of the call, to find the nearest fire/EMS (or police) station, and to get directions for how to drive to the scene of the call.
Where can I find authoritative lists of Law Enforcement structures?
How should I name Law Enforcement structures?
A Prison/Correctional Facility consists of federal and state prisons and juvenile detention facilities. It is important to note that city and county jails are not included.
Where can I find authoritative lists of Prison/Correctional Facilities?
State Licensed and Medicare Certified Hospitals; common hospital types are critical access, general, long-term care, psychiatric and rehabilitation.
Where can I find authoritative lists of Hospital/Medical Centers?
The US Department of Veterans Affairs maintains an authoritative list of their facilities. Only VA Health Care System and VA Medical Centers should be included.
Where should I place a Hospital/Medical Center facility structure point?
Hospital locations should be placed at the center of the primary building in the medical complex.
An ambulance service facility is a building that houses a service to transport emergency patients and administer emergency medical treatment but does not include ambulances operated by fire departments.
For-profit ambulance services generally have their own facilities, which should be captured as ambulance service structure points.
Where can I find authoritative lists of Ambulance Services?
Do we include air ambulance (helicopters and fixed-wing aircraft) locations as Ambulance Service locations?
Air ambulances are included as Ambulance Service locations; however it may be difficult to determine where helicopters and fixed-wing aircraft are stationed. Most hospitals have helipads, but these are not home stations for air ambulances. The home stations for air ambulances generally are at airports. State Health Departments may maintain lists of air ambulance services operated within their State.
US Geological Survey topographic maps were produced from about 1879 to 1992 using a combination of aerial photographs and on-the-ground surveys and inventories. In addition to large more-modern cemeteries, many small cemeteries of historical significance were mapped, and these are included in our database. If you are viewing a listed cemetery location in the Aerial Imagery view of the Potlatch editor, and there doesn't seem to be anything visible there, try switching over from aerial imagery to USGS Topos, and then you often will see the notation of a cemetery on the topographic map.
- The Find A Grave website has a quite comprehensive list; you can search for cemeteries by name or county. The website gives latitude and longitude for most cemeteries.
- The Internment.net has a smaller list which can be searched by county.
- The BillionGraves website has coordinates for cemeteries in its database, and shows the location of the cemetery on aerial imagery. You can search their database by county.
- The USGenWeb Project archives list cemeteries by State and County. It also has cemetery lists as part of its Tombstone Transcription Project.
- The Churches and Cemeteries website lists cemeteries by State and County.
- Check the Data Sources page for your State on this website -- there may be local resources with cemetery locations.
What Address should be given for rural cemeteries?
- Locate the cemetery on Google Maps Classic.
- Right-click on the road at the cemetery entrance and select "What's Here?"
- In the search box, Google Maps will show the latitude/longitude of the point where you clicked.
- In the left pane of the map window, Google will show the best mailing address it could come up with using its reverse-geocoding service. If it cannot come up with an address, it still will show the name of the nearest street, and the city and zipcode of the location.
- If there is a road intersection nearby, put in the road names, for example, "County Road 10 and US Highway 20".
- If there is only a single road nearby, use only the name of the nearest road, for example, "County Road 10".
- If no road is nearby, leave the Address blank, and fill in only the nearest city (and zipcode, if you know it).
Why do we collect information about cemeteries?
"...as a lifelong genealogist, I have been frustrated with the gap between local information about cemeteries and what is easily available in a consistent, reliable, national format. I have benefited from hundreds of thousands of hours of work by others and this is the way I am giving back."
There are quite a few types of Location Types you can choose from, but the USGS guidelines stipulate that only official USPS facilities should be included in the National Structures dataset: this translates to the Post office, Village Post office, and Contract Postal Units location types. To do a search for these three types, select “Post Offices and Approved Postal Providers” from the Location Types list and then click on the Refine search link, and then make sure that only Post Offices, Village Post offices, and Contract Postal Units are checked.
This restricted definition means that many locations that sell stamps or have only automated postal centers or only participate in the PO Box Online program, such as markets, banks, and office and mailing supply stores and other types of Contract Postal Units, do not qualify as Post Offices for the National Structures dataset.Naming Post Offices:
The guidelines stipulate that the correct way to name a post office is: <name> Post Office, for example “Pueblo Post Office”. Also, to naming the Contract Postal Unit, the correct way is: Name+Contract Postal Unit or Name+CPU.
Editing/Reviewing Post Offices for a city or county:
You might want to review all of the Post Offices for a city or county. To do this, go to the USPS Find Locations web page; restrict the search to Post Offices, Village Post Offices, and Contract Postal Units; type in the city of interest; and select a reasonable search radius
