Posters, Events, and Progress

OK, OK. I haven't posted anything in a month, but I have been working on this project! Really! I've made posters and displayed them at events to get the word out and cut regions into the Kingdom polygons. With the deadline of December 31, 2013 looming, I'm focusing on mapping kingdom branches.

There was an East Kingdom Service University on November 23, 2013 in Concord, NH (http://ekserviceuniversity.wordpress.com/).  There were some great classes and I wanted to lead a round-table discussion on SCA recruitment (or "talent scouting") with Sir Kyppyn Kirkcaldy.  As far as I know, there haven't been too many Service Universities over the years, so I figured this would be a good venue for some posters.

The first poster was one I made for The Fort Knox Medieval Tournament in September, which is an SCA public demonstration hosted by the Barony of Endewearde at Fort Knox in Bucksport, ME.  Over the years, I've come to realize that people from all over Maine visit the Fort and see our demo.  Some want to know if there is an SCA group where they live. What a great opportunity for a map!  I collected contact information from each of the groups (including groups just getting started) in Maine and made a QR code for their website or social media page.  I need to work on a few things, but it turned out pretty well.  My goal is to print more of these and share them with the other groups so that we can all benefit from them at other SCA demos.  I'll be elated if anyone pulls out a smart phone, scans the QR code, and contacts the local representative.  Fingers-crossed!

The next poster was for the SCA Known World Mapping Project.  Because the East Kingdom is mostly mapped, I used it as a proof of concept.  It show the extent of the East Kingdom, the regions and Principality of Tir Mara, and the local branches.  It introduces the project team, goals, progress, the smart phone/tablet app, and this blog.  I kept the "WGS 1984 Web Mercator Auxiliary Sphere" projection in the three main maps, which I should probably change.  It makes Canada look HUGE and the rest of the Kingdom tiny.  Labeling the state-side branches was a bit of a challenge and later discovered that a couple didn't get labeled.  Oops.  All-in-all, it's a good start.  I even saw a slight bump in blog views!

The maps are taped down to foam-core, poster board which I left in the trunk of my car after the Service University.  I brought them to our fighting and fencing practice the following Sunday, where my daughter is a youth fencer.  Mistress Mercedes, EK Seneschal & New Groups person, was there and had a question about the location of a group.  I brought the Known World Mapping Project map of the East Kingdom in and she quickly discovered that it would make sense for a certain incipient group to be part of the Central Region instead of the Southern Region.  Maps can certainly help make informed decisions!

Both maps have since made trips to the Herne the Hunter event in the Barony of Ruantallan (Halifax, NS) and the Barony of Endewearde holiday revel.  The feedback has been positive and suggestions for improvement or corrections have been made.  I certainly appreciate the interest and cooperation.

Cutting the Kingdom regions into a copy of the Kingdom polygons was pretty easy.  From what I can tell, Trimaris doesn't use regions, Meridies and goes by state boarders, Atlantia, AEthelmearc, and the East use state/country boundaries and branch divisions.  There were a few hiccups along the way for unaccounted ZIP/ZCTAs codes, but they are mostly figured out.  I hope to post that map data shortly.

The big hurdle is corroborating ZIP code lists by the Kingdoms to the ZCTAs.  So far I have found orphaned ZCTAs and a few claimed by more than one group.   There are also questions based on published maps compared to what the Kingdom list/mapped ZCTAs are showing.  I suspect one is more current than the other.  I think there is going to be a beta period to work out the errors.  Once this is done, I'm sure the Kingdoms will appreciated updated ZIP code lists for their local branches.  It's easy to see that this project is going to take a bit of work to keep it updated.  (Let's worry about that later...).

That's it for now.  The work continues!  =)

Progress Report for Friday, 11/8/13

Over the last week or so, I've had a chance to consider the data structure, start looking at linking tabular data to spatial data, think about deadlines, and add a ZIP code basemap to my EK demo map. Here's where we're at to date:

There are 5 people working on this project, so naturally, we'll have 5 methods for getting to our goal. It was agreed we wanted an interactive map that would make it easy to find which SCA branch a particular ZIP/FSA code fell into. One way would be to simply assign a branch to a ZIP/FSA code and show it on a map. That's fine in a desktop software application, but we also want to serve it up in a map on the internet. The limitations here are file size, the number of features (records in the table), and complexity of the geometry. Basically, we can't upload all of the ZIP/FSA codes to the website and expect the back-end servers to render that much data. We have to dumb it down a bit. This means dissolving the ZIP/FSA codes to the branches. Then, if we want to zoom out to see Kingdoms, zoom halfway to see regions, or zoom in further past Baronies & Shires to see cantons, ridings, colleges, ports, or stongholds, that has to be in the dataset as well. We can dissolve the ZIP/FSA polygons to each level. That means there will be a Kingdom level, regional level (Principalities or groups of branches for those kingdoms that have them), a Barony/Province/Shire level, and a canton/riding/college/port/stonghold level. Breaking the ZIP/FSA codes down this way means that at a minimum, the table must have these four columns. The added benefit is that we can show which local levels belong to which parent levels. OK, so I've spent a lot of time thinking about this, but it seems logical to me. (Another complication will be islands and coastlines, but I'll get to that later.)

So now that I have spreadsheets of branches by ZIP/FSA codes, I'll need to link them to the corresponding ZIP/FSA polygons. Linking the data based on ZIP/FSA codes is pretty easy, it's the clean-up that stinks. There will undoubtedly be orphaned ZIP codes because the polygons are ZIP Code Tabulation Areas (ZCTAs). ZCTAs are ZIP codes used by the U.S. Census Bureau. You can read more about ZCTAs at this website: http://www.unitedstateszipcodes.org/.  Anyway, there are more ZIP Codes than ZCTAs.  Also, ZIP Codes get added and deleted all the time, so we're bound to find some that local Seneschal's missed or are legitimately "Crown Lands" unclaimed by local branches.  This clean-up will probably be the most time consuming part.

With so much work to do, knowing timelines and deadlines will help.  Most of the SCA Known World Mapping Team will be discussing this Saturday evening (11/9/13).  One deadline mentioned so far was by the end of the year.  That's about seven weeks from today.  Seems reasonable (I hope).

Finally, there has been this idea that we would want to see the ZIP (ZCTAs) code boundaries.  Luckily ESRI has done this work for us!  I'm not sure how they did it, but the layer can be added to the map and rendered the way we want to see it.  I've added another page to the blog called, "SCA EK Branches with ZIP Code Basemap".  If you zoom down to the local branch level, you'll see the ZIP code polygons.  Pretty neat!  I'd still prefer to enter a ZIP code and search/zoom to it though.

This project is still a work in progress, but a labor of love.  I'm excited for people to use it.  =)

Embedded Maps

Out of the blue this morning, it occurred to me that it's possible to embed ArcGIS Online maps in websites and Blogger allows you to create additional pages and view the HTML code in the editor.  Putting the two together, you'll notice a "Pages" section to the left and a link to "SCA East Kingdom Branches Demo Page".  Go ahead and click it.  I'll wait....

Cool, eh?  I don't know why I didn't think of it sooner.  I imaging Kingdom Web Ministers will want to do this with their sites too.

Working Smarter, Not Harder

If one had a field of barley to harvest or bushels of grapes to crush, it would be good to have friends.  Medieval crowd sourcing?  Well, I'm glad to have friends willing to comb the inter-webs for website info.  You can read more about it here:

Sorting and Classifying Kingdom ZIP Codes

In order to map SCA branches by kingdom, the ZIP and FSA (Forward Sortation Area - Canada) codes have to be classified by Kingdom, region, primary and subsidiary branches.  These classifications will be scale dependent in the final map.  To develop the map, each Kingdom provided a list of ZIP/FSA codes by branch for this project.  Quite a bit of reformatting and editing was required to get the data "database ready".

The final product of this project is an interactive map that revels SCA groups at different scales (or zoom extents).  So if someone zooms out of the map far enough to see North America we should see Kingdom boarders.  Zooming to the region and state level should revel regions within a Kingdom.  Zooming to the State and county level should show Baronies and Shires.  Finally, zooming to the Barony or Province level should show the Barony proper and any cantons/ridings or colleges associated with the Barony or Province.  Keeps and Ports will figure into this as well; though the associated ZIP codes may appear as points rather than areas.

The map design means that each ZIP/FSA code must have a Kingdom, region, primary and, if required, subsidiary group names; where the type of group is part of the name for primary and subsidiary branches.  It's a database thing.  This ZIP/FSA code list will be used to link to a spatial database of ZIP codes.   We are effectively adding additional information to a map point or polygon ZIP/FSA code.

As you can imagine, each Kingdom has a different method of formatting these lists in a spreadsheet.  Most provided only the branch name and list of associated ZIP/FSA codes, while others included the region, type of branch and associations with the ZIP/FSA codes.  For example, in the former case, only the group name and list of ZIP codes was given and in the later case, the type of group (Barony, Canton, College, Shire, etc) and name plus which Barony the Canton or College belongs to as well as the ZIP/FSA codes were provided.  In order to get the information provided into a standard format for the spatial database it was necessary to "fill-in-the-blanks".  It's fortunate that SCA membership affords us the ability to download newsletters from other Kingdoms than our own.  I downloaded the AEstel, Acorn, PikeStaff, Popular Chivalry, and Talewinds newsletters to classify the ZIP/FSA codes.  Each newsletter has a page with group contact information.  Simply listing the names made it possible to determine the region, type of group, affiliation to a parent group, and even the correct spelling of a group name.

Once the ZIP/FSA code list is completely classified, it is possible to summarize the data.  Microsoft Excel's data filtering and Pivot Table tools makes this very easy.  A count of regions, groups within a region or Kingdom, or a count of groups by type is done in a matter of minutes.  A count of ZIP/FSA codes is helpful for the kind of data preparation this project calls for.  Here is a draft summary of the Kingdom of AEthelmearc:

Shire of Angel's Keep 7
Shire of Coppertree 118
Shire of Courtlandtslot 15
Shire of Sterlynge Vayle 88
Shire of Wynterset 65
Grand Total 3,361

In this table, "(blank)" is the barony proper, not the canton or college count of ZIP codes.  There is also the question of the Canton of Steltonwald having ZIP codes in two parent groups and the "2.3" region.  However, we can see that there are 5 regions, 29 baronies, shires, and a "Dominion", as well as 3 cantons and 1 college.  Altogether, there will be 3,361 tabular ZIP codes that need to match polygon or point ZIP code features.
