GIS and Related Pursuits


A Review of Maps.Familysearch.Org is on of the bigger genealogy websites with a large repository of digitized and microfilmed documents, a huge collection of pedigrees, and online pedigree management tool among other things. They also have an ongoing FamilySearch Labs program where they try out new technologies and product concepts. One of their current Labs projects is

Historic Maps of England

They currently only have maps of England available and only for 1851. For 1851 you can choose a variety of overlays including the parish, county, poor law union and province boundaries. For some types, such as parish boundaries, you can click a parish and get an info box indicating when records are available for that parish., or click a county and get a list of parishes in that county.

Hope for Future Directions

The current state of is a single point in time for a single location. If the project makes it out of labs I hope and expect that they will extend it worldwide and across time. Geocoding the boundaries for their many datasets of genealogical records would be quite a process, but FamilySearch routinely undertakes and is involved in huge digitization projects and does a good job with them.


A Review of

Welcome to my spatiotemporal GIS blog! Here I intend to publish reviews, questions and links to interesting studies, presentations and products dealing with old maps, GIS, GIS and genealogy and anything else tangentially related or interesting.

We’re going to start it off with a short review of which describes itself as “a new platform for describing the world of the past“.

Pastmapper presents San Francisco in 1853, 1914 and 2012 and San Mateo in 1853 and 2012. It overlays the old city directory information as points of interest on the map. They have several city directories available for different cities, but it doesn’t look like the other cities have been mapped yet.

One thing I really like about Pastmapper is that they provide a separate base map for 1853 and the present, allowing you to see how far San Francisco has extended into the sea. The points of interest don’t move between the two maps, and there’s no indication of which points are still around and which have disappeared. This is beneficial if you’re trying to find the present-day location of an old establishment, but could be confusing if points of interest were shown from more than one time period, or if more than one time period were available.

In one of their blog posts Pastmapper says “Online maps today simply add layers of information onto today’s map. Pastmapper is a first step towards answering ‘What was here?’ or ‘Whatever happened to..?’, by delivering a map, not just a data layer, that takes a fourth-dimensional view.“. On this count Pastmapper does a nice job.

Their main page says that they are a “new platform for describing the world of the past” but it’s unclear when Pastmapper will be available for others to use, if at all. What’s on the website is an Alpha release, so it’s possible that we’ll all get to play with it some day with our own data and locations.

Lastly, for anyone who is concerned about the state of the project a tweet from just a few days ago indicates that the project is still alive:

My brain is exploding thanks to @andrewxhill‘s talk on @cartoDB at @sotmus. Pastmapper will be getting cooler soon.


Hopefully we’ll see some updates we can play with soon!
