Now we know where to focus our efforts. Most excellent work, Belemnoid!

Hey Belemnoid,
Thanks for hooking that up. Can you do me favor? Can you do the Jersey one? I'd do it but I don't know how. I would appriciate your help. Thanks.

I'd like to see one for North Carolina too. If it's not too much trouble.

A little in the Jersey area, next to nothing in NC.

Thank you....that's most helpful!

blemenoid... You Da Man!

Thank you so much!!!

Just a note about the methodology of these maps - they were created using a Density tool that requires the user to enter some parameters. Most import of these is the "search radius" which is the unit of area that it's using to calculate density. For these that unit is one square degree of long/lat which is a damed big area. Ideally I would use the know range of a BF - but who the hell knows that?

The other thing I left off the maps was the scale for density. The range is 2.4-4.9 sightings per sq DD for the darkest green to 22-24.5 for the reddest red. That means that even for the densest region you're still talking just one per every 100 square miles or so (assuming I got all the math right).

Thanks dude, now me and my son know just where to go.

What about one for Northeast NY VT and Penn or Ohio

BTW, I found that putting my cursor over the "Full Size" image gives a "magnifying glass" with a + inside... by clicking the left mouse button it allowed me to get a full-page sized map and they print up very nicely.

... and by saving the image and changing it to 800 pixels wide by 1235 pixels in height, it prints out in nice one page format.

Quick reply id have to say there it a lot more sightings in the olympic mountain,coastal areas of washington than that map even comes close to. check out the the maps on the WSSSG page.

What type of calculation is used to determine the "centroid of squatch activity", with respect to the color coding?

Actually I think that is fairly accurate based on reliable reports posted on the BFRO website. I have a DeLorme Gazetteer for Washington and have all of the currently posted case reports marked on there (for ease of reference for some research I am planning) and the distribution pattern seems very similar to what Belemnoid has indicated on his map. I've found no other source with comparable credibility to the BFRO (short maybe of John Green) and that is why I limit my documentation of sightings into my database that I am creating to those sightings investigated by the BFRO (or by individuals whom I trust).

Having lived in washington for the past quarter century.There have been numorous reports king county, pierce county{fort lewis }.central cascades.other than "maybe the central cascades . i would waste my time.The 'Hot Spots 'In order would be Greys harbor county all the way north thru the olympics mountains to Port Angeles. Skamania county all around Mt St Helens hwy 2 north past mt baker to BC. , some parts of eastern washand. and some areas around Mt Rainer . IN THAT ORDER.

I used only the BFRO data that Mangani had mapped out on his Delorme software and shared with the forum. I belive his database has been updated to include some Texas data but that's about it. If you have another source of good data I'm sure he'd be interested.

from the software help file:
"By calculating density you spread point values out over a surface. The magnitude at each sample location (line or point) is distributed throughout a landscape, and a density value is calculated for each cell in the output raster.

Density maps are predominantly created from point data, and a circular search area is applied to each cell in the output raster being created. The search area determines the distance to search for points in order to calculate a density value for each cell in the output raster."

The search area in this case was a degree of lat/long

The color coding was simply breaking up the values into 10 bins and using a red/green color ramp.

If you have a source of good data other than BFRO, I'd be interested as well....please let me know.

Your Washington/Oregon map looks quite close to The Bigfoot Research Project's regional data. Independent confirmation and repeatability of results are always good.

Would you mind doing a map for Florida?

Regarding the range of individual Bigfoot... I might be able to help you out there.

Cool. The map for NJ should have the 2-3 sightings from Harriman St Park in NY included as they are within 10 miles of the NJ border, and on the map as presented.

That is excellent!!!!!

Here are the favors that I will ask of you.

Can you do one of Michigan and Indiana? (together or seperate)

How about the whole country or the country in quarters?

THANK YOU

The country-wide maps can be found on this thread:

Nationwide maps

Michigan/Indiana and FL should be up by the end of the day.

Sorry, busy today.

Just links to the large versions of those two maps.

Michigan

Florida

blemenoid awesome work, most thanks for posting this, I am surrounded by class A sightings and am thrilled!

Cheers!

Could you do a map for Canada? Bigfoot researchers don't seem to have done much analysis of Canadian sightings.

sorry, there's not much in this database for Canada other than a tight cluster near the town of Fisher Branch in Manitoba. I don't know if this is because Canadians don't report to the BFRO or because there are more moose than people up there, or because there just aren't that many sightings.

Great Work! How recent are those or does it matter?

They were up to date the week they were originally posted, but that was about a month ago. They only go back as far as 1990 as that's as far as Mangani (whos data I used) has managed to get.

Joe Beelart put forth his ideas on sasquatch ranges in an appendix to his book. He called them SSA's, Standard Sasquatch Areas. As I remember, his opinion was that they were roughly 250 square miles in area. Of course that is based upon PNW habitat and my failing memory.

In Ohio, there are a number reports of a white bigfoot. Dad says he has video, but it is one of those deals where he says prove it is not and others say prove it is. On this forum, many would put it in the blob, or maybe specsquatch HOF. Anyways, the reports of Ol' Whitey range in a diagonal from north of I-70&77 to just north of Cincy, which is 150 miles. That assumes it is the same white one, of course. And that may be a factor that might skew the data. The maps are really nice, I think they probably represent the density of reports more so than the density of populations. Is there a correlation between the two? Absolutely. How strong is that correlation? Not sure. Nice project, none the less. Thanks for sharing.

Yep. And I have a lot of other things going on right now so it will be a long time until I even start on the pre '90 BFRO data. Since it took me three years to map all of the 1990 to 2003 data, I expect it will be quite a while until I get all the older sightings mapped.

On the plus side, I am keeping up with mapping post '90 sightings as they are added to the BFRO web site. I usually update the map data files weekly.

I've been picking at geolocating BFRO's database for a couple years as well. Without regard to year. I started in my own state and am moving out to adjacent states.

Belemnoid, I'd be interested in knowing how you SO QUICKLY convert Mangani's downloaded coordinate file. Is there an automated way to do that within ArcGIS (yes I have access to this program, including Spatial Analyst.) No offense to Mangani, but the file looks to the eye like a jumbled string of numbers and words.

So even with Mangani's excellent work in TopoUSA, I find it quite a manual task to convert those datapoints into a GIS.

How ya doin it?

I started with my state as well but when I saw what mangani had provided I stopped working on it. I might go back to it someday as it was all of the sighting for my area and not just the post-1990. But for now his is superior.

As for converting in......It's not completely automated but it's a lot faster than doing it manually. I download the .txt version of his data and import it into excel. This works for everything except the url as the rest is comma deliniated. I parse out the urls and then save the file as a .dbf. Once that is done you can bring it right into ArcMap and have it create points from the x,y data.

:hvymtl: Ben Seaver here. the Ohio hot spots are where my brother and I have been investigating.mostly West branch, and Berlin.Berlin has some strange things happenin out there.there were a bunch of dog dissapearences,last summer, at the same time, multiple sasquatch sightings.unfortunatly we found out through newspaper articles. we spent 2 weeks there,last month.found some tracks ,but nothing substantial, also we found what appeared to be dead rabbits up in trees. 2 of them. I know from my own experiences that bigfoot dwells in trees , being so , both my brother and I witnessed one coming down out of one, years ago.my aunts friend had a sighting in palmyra, 2 miles from West branch,15 years ago. A friend of mine, saw him once in Champion Ohio.another friend had an encounter down near Dayton, while coon hunting.and also I know a man that followed tracks for 2 miles starting behind his house into the woods. there was snow on the ground, he said about 4 inches ,and at first he wondered what kind of a crazy person would walk around barefoot in the snow. upon comparing the size of the tracks to his own , he realized it wasnt a man!that was in Freedom township. My brother and I had 2 encounters, here... definatley a HOT SPOT !!!

It would be interesting to see maps of number of sightings compared to population density.

This is where Skamania county stand out!

More Moose than people!

In some areas, that is actually correct!

First off, GREAT JOB!!! This is very cool and Im a sucker for maps.

I have to say that the Texas map looks a bit sparse on the encounters indicated just North of Houston (SHNF area). For example, I have a total of 20 BFRO reports just in the four county area of Walker, San Jacinto, Montgomery and Liberty. Liberty and Walker were all Class A sightings and made up 13 of those.

PullTab,

Please remember that my data currently include only reports of encounters since 1990. For the Texas counties you mention I have inluded a total of 18 reports, so we really are not very far apart. Also note that Belemnoid has to convert my data files to use with his software, and he may not have taken the time to pick up the latest version of the data before he did the Texas map.

That said, it's certainly possible that I have missed a few reports, since I am doing this solo and there are a lot of data to review for the entire US and Canada. Anyone who wants to check and correct my work is very welcome to do so.
The files are available at BigfootMaps.

I am slowly adding the pre-1990 reports one state at a time and this allows me to check for any post-1990 reports that I missed the first time around. I have been picking up a few class Bs that I left out previously.

Tanks for the BF maps, Mangani!
