Big upgrade to the Section Township and Range tool: more detail, more flexibility, new labels

After the infrastructure upgrade I mentioned in the last post, the increased speed of the maps enabled me to add much more detail to the very very large map layers (over 12 Gigabytes!) that comprise the Public Land Survey System (PLSS), also known as Section, Township and Range.

When you open the tool, you will now be presented with a Google Map overlaid with township and range lines, including labels, such as this:

Note the Township and Range labels above.  For example, the box where the red dot is has a label "14N 67W" which is shorthand for "Township 14 North, Range 67 West".  (Note:  If you get a message that says "Area not covered" when you open the tool, then you're looking in an area that doesn't use the PLSS)

As you zoom in, progressively more detail and labels will appear, such as the Section numbers shown here:

And if you zoom in REALLY close on one township, you will even see the quarter quarter sections and their labels.  In this example, we can see the red dot in a box labeled "NENW", which is shorthand for "NE quarter of the NW quarter" of section 36:

TIPS and reminders for how to use the Section Township Range on Google Maps tool:

1. Search for any address, city, place or even GPS coordinates by using the "Search places" box above the map:

The panel above the map will show it's section, township and range, such as when I typed "Pikes Peak, Colorado" and got this information:

2. If you know a Section, Township and Range you want to find (for example, from an old deed such as BLM Land Patent records or a current land description), use the "Find Parcel" panel below the map.  TIP:  If you don't know the Section number, just leave it blank.
In this example, I specified Township 4 North, and Range 69 West, 6th Principal Meridian, Colorado, then clicked "GO!" and got this map with the township highlighted in yellow:

If I had specified a Section number, the map would have zoomed in all the way and highlighted the section:

TIP to speed up entering info into the Find Parcel panel:  Use the TAB key to move between boxes, and type the first letter of each drop-down (e.g. type S for South, type C twice for Colorado).  Click "GO!" when you're done entering info.

3. Geeky fun:  If you want to know what Township, Range and Section you're in right now, use the  button in the upper right corner of the map!

4. As always, share this tool with friends that might find it valuable!

Remember, the Township Range Section map layers are VERY large (did I mention they're over 12 Gigabytes?) and drawing time may sometimes take a while, especially if there are a lot of labels.  So, on occasion the tool will require patience :)

Hope it helps you in your research!

A quick update on the increased speed of the mapping tools

After some infrastructure upgrades, all of the mapping tools are now operating faster!  In my time tests, I was seeing drawing speeds that were 2.5x to 3x faster than before the upgrade.

The very largest of map layers, such as Section Township Range on Google Maps, seem to see the biggest improvement (drawing in 5-6 seconds now vs 25-30 seconds before the upgrade), although other layers such as Historical Counties, County Lines and ZIP Codes also drew about 2x faster that before.

So you should on average see the information panel above the maps update a bit faster and see the maps draw a bit faster, especially when zoomed in to the state level or closer.  Enjoy!

This update applies to all of the following tools:

Overlay present-day county lines on the Historical U.S. Counties on Google Maps tool

Based on an idea from a current user (thanks Steve!), there's now an option to overlay present-day county lines on top of historical county lines.

This gives you the ability to see at a glance if you're researching in an area and timeframe where the county lines have shifted between the historical date you're viewing and the present-day.  To use this feature, just check the "Also show present-day county lines" checkbox in the lower left of the map on the Historical U.S. Counties on Google Maps tool. 

When you check that box, you'll see thin red lines (present-day county lines) overlaid on top of the thicker brown lines (historical county lines).  You'll also see the "Present-day County" name listed in small red text above the map (next to the latitude/longitude).

As an example, let's say we're researching the Nashville area as of 15 Jul 1830.  (Type Nashville in the "Search places" box above the map and type 7/15/1830 in the "As of date" box above the map).
Then, check the "Also show present day county lines" checkbox, and you'll get a map that looks like this:

On the above map, I've highlighted in yellow where the present-day county information is shown, based on the exact location of the red dot on the map. This tells us that this location was Davidson County, TN in 1830 and today, it still is Davidson County.

But, see the faint red lines in the above map?  Those are the present-day county lines.  So we can clearly see that the western side of Davidson County in 1830 is another county today, as is a small section in the southwest corner of 1830 Davidson County.  To find out what present-day county is in those two areas, just click the map.  You'll get this:

The above map shows us that the western part of 1830 Davidson County where I clicked (the red dot) is now Cheatham County. 

This alerts us that if we are researching an ancestor who lived in Ashland City in 1830 (see the northwest part of 1830 Davidson County), those records may be housed in Davidson County's courthouse (barring the court house didn't burn down!).  Importantly, it tells us that if we're doing an 1830 Census search on Ancestry or FamilySearch (for example) for those ancestors that lived near Ashland City in 1830, we should make sure and filter the place based on Davidson County since that is where Ashland City was located in 1830 (even though it's in Cheatham County today).  I wrote an in depth how-to on this topic here:  How you may be sabotaging your search for ancestors...and how to fix it!

What about that little southwestern part of 1830 Davidson County?  What county is that area part of today?  Well, you'll have to go to the Historical U.S. Counties on Google Maps tool and find out!
