GeoGenealogy:
Geography for Genealogists
Geography can be a genealogist’s best friend.
Understanding the geography leads to understanding jurisdictions, which helps locate records. It also can assist or suggest a
direction for research. http://freepages.genealogy.rootsweb.com/~genmaps/
and http://geonames.usgs.gov/pls/gnispublic/f?p=133:1:1966716235342276351
are great examples of geography resources online. As good as they are, they are merely great reference tools where you can look
up the desired information. Another good tool, is the
England Jurisdiction project from the Family History Library. It has
tremendously valuable data, but is still just data. An early application that
attempts to make this data more useable can be seen at http://www.familysearch.org/eng/Library/FHL/frameset_library.asp?PAGE=english_probate_jurisdictions.asp.
As good as this is, we need to apply some imagination to think of what else
could be done with this data.
The future of such a project might be that I could
enter a place name, a family name, and a rough time period. The program would
then identify the place, find records from that place or other places nearby,
search those records for the name I supplied, and return the information from
the records. This would be possible if the location data were geocoded and the records themselves were indexed (both of
which are do-able now…)
This session will focus on new ways of providing
useful geographic information over the web through geocoding,
geotagging, and mashups.
GeoCoding
A geocode is a
geographical code to identify a point or area at the surface of the earth. (Courtesy of Wikipedia). The code systems can be described
by:
* how the area is coded (number, letter,
mixture of both, other)
* which part of the earth is covered (whole
earth, land, water, a continent, a country)
* what kind of area or location is coded
(country, county, airport, railstation, city, ...)
* whether an area or a point is coded
* time for which the code is valid
Geocoding is the process of assigning geographic identifiers (e.g., codes or
geographic coordinates expressed as latitude-longitude) to map features and
other data records, such as street addresses. You can also geocode
media, for example where a picture was taken, IP Addresses, and anything that
has a geographic component. With geographic coordinates, the features can then
be mapped and entered into Geographic Information Systems. (Courtesy
of Wikipedia). Geocoding allows for
each piece of data so coded to be tied to a specific spot on the earth. That
spot can then later be identified by GPS device, plotted on a map, or used to
determine distances between two coded spots.
A geocoder is a piece of
software or a (web) service that helps in this process.
Geocodes can be added to photographs, digitized
documents, and a variety of things in electronic format. The Geocode becomes a type of metadata, which can be imbedded
within the electronic file itself. There are digital cameras which come
equipped with a GPS device. The GPS uses satellites to determine the specific
spot (within
GeoTagging
GeoTagging is the
process of associating the geographic location with an item, such as a photo,
certificate, or other digital record. It remains to be seen if the concept of
community or volunteer geotagging can help the
genealogical community. One such project is called GeoTagThings
at www.geotagthings.com.
This concept
has a lot of potential to benefit genealogists.
GeoTagging opens
possibilities of taking data that has been tagged (or marked up) with geographic locations and doing things with it
automatically, based on the location represented by that tag. For example, if a
birth record gives a location and the birth record has been geotagged
with the location, it becomes possible to represent the birth record on a map.
This is what makes geographic mashups possible.
Mashups
A
mashup (web application hybrid) is a website or web
application that combines content from more than one source (courtesy
Wikipedia). Thus one can take a geotagged
genealogical record database in one source (or on one website), and mash it up
with maps on a web site which has nothing to do with the genealogical database.
For example, Zillow is a popular mashup which pulls information from sites about real estate
sales, and presents that information on a map from a different site. The result
is a map which shows individual homes with their value. It has nothing to do
with family history, but it illustrates the idea – see www.zillow.com.
Provo
Labs is an exciting new company in the genealogy community. Their first major
offering is WorldVitalRecords.com. At this site, you can search data that
has been tagged with geographic locations. This mashes up with Yahoo! maps to display markers on a map represented
by the data. You search the database, get results, click on a result of
interest, and get a map of the area showing the area where the event took
place. Social Security Death Index,
The
Foundation for Online Genealogy is another new company in the genealogy
community. Their first product is WeRelate.org,
a cooperative site that seeks to enhance good tools through individual
participation in the improvement process. At this site, you can search names,
places, or sources and then map them through a Google maps mashup. The mapping portion is only visible when doing a sources search
at www.werelate.org/wiki/Special:SearchSources.
They have drawn information from a variety of sources, including the Family
History Library Catalog. Try a source search for a state or country and enter a
record type into the keywords field. Once you’ve found a record for a
place, you can edit the results to add additional valuable information, which
will then be available to future visitors to the WeRelate
site. It’s an interesting idea, with a lot of potential for the future.
The US GeoGen
Project® (www.geogen.org) is a national
project designed to combine the hobbies of genealogy and electronic
orienteering. Genealogical research often involves geographical research or
visualization, even looking for cemeteries and other sites from your
ancestors’ lives. Electronic orienteering is the use of global
positioning devices (GPS) and maps to find things that may otherwise be
difficult to find. The specific goal of the US GeoGen
project is to create a national network of county oriented pages listing
locations of interest to the genealogist along with their geographical
coordinates, so that all researchers can easily find the locations. Their list
of place types include: Cemetery, ghost town, monument, mine, homestead, or
historical Post Office. You type in the name of a place in the box marked waypoint, pick the state and type of
place, click search then wait for a response. You get back a list of places by
that name, with the ability to see a current map of the place in Google Maps.
www.genooglegy.com
(a play on the combination of Genealogy and Google) is not yet available, but
is an anticipated release from BYU. The basic idea is to take a GEDCOM, extract
all places mentioned in the GEDCOM, and then to map those places on a Google
map. This would help a user to see geographic relationships between their
ancestors and might also point out some inconsistencies or questionable
locations.
GenMapUK (www.archersoftware.co.uk/genmap01.htm)
is a software product rather than a web site, but does some useful things with
place data—either in a GEDCOM file or a pre-formated
data file from a genealogical source, like the IGI. It can do surname distributions,
event maps, and a variety of other visualization tools. Take a look at their
web site for more information. It is probably only a matter of time before
someone offers this same service on the web.
www.shawngo.com/gmaps/states.php
- this is a new site that attempts to show things on a map. So far, I
haven’t been too impressed by it—except for the fishing sites map.
I mention it here as an example – and who knows, it may become more
useful in the future.
Goldbug’s SiteFinder (www.goldbug.com/map/sitefinder.html)
asks you to input a place name. It then locates the place and plots it on
Google Maps in a basic mashup. Goldbug
is well known for Animap Plus, a software program
which animates the changing boundaries for each county of the 48 states from
colonial times to the present. For an example of what an Animap
animation looks like, check out www.tngenweb.org/maps/county-ani/tn-maps/tn-cf.html.
http://jrshelby.com/hcl/ has links to great sites showing the
changing
National Gravesite Locator - http://gravelocator.cem.va.gov/j2ee/servlet/NGL_v1
helps to locate veteran gravesites, showing maps of the cemetery in which they
are buried.
