I love the overlays of old & new maps!! Nice lecture.

This guy needs to be teaching a course in how to recognize maps! He is great!

Does the Museum have any maps of the Interior Basin of the West prior to the Dominguez/Escalante expedition?

Excellent presentation. Thanks so much for uploading this.

@7:30 the city in bavaria is spelled Landshut not Lanschut.

Another interesting reference, is the "The Story of Maps," by Lloyd A. Brown published in 1949. Does not cover most modern methods but good historical reference.

Why are here so many hate comments on this man?

Interesting content but the audio quality makes it difficult to watch.

loved this presentation.

Is this a video on maps or flat vs globe earth? Let’s stay on topic professor.

Anyway good video but still wondering if there is a best strategy they used to get a good sketch of things probably wasn't until gps or recently with radar/digital imagine that we could get depth calculations so they probably could only do rough sketches of the world not even sure they could put lat and long in the first maps they may have just focused getting the picture right

Most of us know the earth is round. If we were to take an old/ ancient flat map and compare it to current round map is the total size of the earth the same on both maps?

Interesting that there’s no mention of Ahmed Muhiddin Piri!

Ok, well, what i've learned is that i'm not as interested in old Cartography as i am in old Land Surveying. Dragging a compass and chain thru the woods sounds like a good time to me!!!

In his book, "Voices of the Rocks," Robert Schoch attempts to debunk the undebunkable Piri Reis map. Dr. Schoch asks his readers to believe that Turkish admiral Piri Reis started a three-year map project on a piece of gazelle skin that was too small for the map, and so had to bend South America's tip to the right to fit the parchment. In fact, the rightward curving land-mass is South America's tip correctly joining Antarctica, as Lt. Colonel Harold Z. Ohlmeyer of the U.S. Air Force confirmed on July 6, 1960. (Piri Reis's map is on the left in the black and white graphic below.) ". . . Schoch concludes [in his book "Voices of the Rocks"] that [Piri] Reis's depiction of Antarctica may not be Antarctica at all but in fact simply the lower reaches of South America . . . "The sole evidence that Schoch gives for his opinion is that the lower portion of South America curves east on the map. Schoch attributes the curving of South America's tip to Reis running out of room on his gazelle-skin parchment. Mimicking . . . Wikipedia, which states that "the 'extra' landmass is simply the South American coast . . . bent round to fit the parchment," Schoch states that "the supposed coast of Antarctica could well be the lower reach of South America." "To make the statement above, Robert Schoch . . . had to believe the following: that Piri Reis, a man competent enough to navigate the ancient seas, was dim-witted enough to start a three-year map project on a piece of material too small for the map. "Not only did the project take Reis three years to complete, it was a project that included translating from different map scales and projections, a phenomenally challenging task that very few people on earth could perform successfully today. . . . "In fact, as simple research reveals, the reason the lower part of South America is curved to the east on the left-hand lower corner of the map, and the reason that the continent of Antarctica looks as if it might be South America's extended tip at the bottom center of the map, is that Piri Reis used an azimuthal equidistant projection, a sophisticated cartographic method that gives more accurate relative continent sizes than the modern standard of cylindrical projection, which unnaturally enlarges polar-region continents." - Jock Doubleday, "Witchcraft Cartography and Clairvoyant Archaeology: A Review of Robert M.

? so Eratosthenes calculates by simple math at the equator a reasonable 24000 miles , and so with the 7.2 degrees and 480 miles, the same simple math triangulates the sun as 3800 miles above that well in Egypt ? what is the earth diameter at the equator ? why did captain cook estimate he sailed 60000 miles around the world in over 3 years as close as he could get to antarctica ? all the information was there when i left school 30 years ago !

ha reading the comments, im amazed how bent out of shape some people get about this subject. further down there are some really nasty comments ha ha. i enjoyed this very much, thank you😇

I would LOVE to HEAR what he is saying.. Everytime he turns away his voice fades off... Very frustrating!

Regarding the diagrams at 7:30; the moon's shadow isn't governed by the shape of the earth.

It's a fairly new invention; It's called a microphone............but, you have to know how to use it!

The main problem with the shape of Michigan-the-State is that there are only four Great Lakes, not five. Lake Huron and Lake Michigan are one lake with two arms - not two lakes. A lake, to a cartographer, is drained by a river.

Ohio was the testing ground for various grid systems for the USPLS.

It's written in stone that they had flying vehicles back in Ancient Babylon.

Microphone setup??? Sorry,the video could use some work.

Had to stop watching due to audio fluctuations due to mic dislodge

Talk into the microphone!

14:20 I see damn face there

Nayef Al, Then how is it there was a map of Rome carved in stone in AD 200, look for "Forma Urbis Romae" ... and Islam got started when, Habibi?

@0:01:17 at least he knows earth is flat

Who sees a face in the map at 14:00?

I'm just wondering how 24,000 is within 9.5% of 24,860. I guess I'm just stupid because every way i try and find the proportionality I get anywhere between 3% and 3.58%. Someone tell me I'm stupid and then begin to show the correct way.

We know that the blue marble photeo is real because the clouds in India ocean spells SEX....HAHAHAHAHAHHAAH

Love the guy's bow tie. He probably has a pocket protector, too.

nja

good explanation but i think i would be lost if somebody ask me to start making a map of the world . i think even if I used the mountains it would be relatively difficult to get more the a few good pieces . And you have to be good at art to. I think when planes started to come out and people could fly up in the air taking photos then map making could be done more and more accurate or at least validate to the real thing... even more so with space pictures and digital imagine as we have today

Clacton girl Sade!

Looking at the map It looks like they made it from a unpractical distance

This guy needs to wear a lapel microphone.

the clouds on horn of Africa is Arab letters Haha

What if when the Chinese traveled by the world seas would have a balloon 🎈 on their Ship extended someone who knowledge of land sketch from a higher level, on a basket a huge scale balloon with a person in the basket with ropes. The Chinese traveled with a number of different types of necessities, weapons, food, water, Forget it I could go on !

Maps and charts were made to scale with angles. Starting with observations to features from two points called a baseline intersecting bearings create triangles to scale establishing the position of all points to scale including the baseline. No distance is needed to start Explorers used Mountain tops to establish the position of points below. Navigators used peaks and coast features for map. Latitude and longitude was invented before the bronze age to do several things. It invented hexidecimals for an angular grid of 360° 60' 60" (DMS) on the stars measured from the centre of the Earth. The ratio of 360° (degrees) with 60' (minutes) for each degree and 60" (seconds) for each minute also divides the surface of the Earth for pragmatic Distance Navigation into standard radian Nautical Miles each minute of latitude of 1000 standard fathoms. It is inherent within the DMS ratio because pragmatically a thousand fathoms (6000 feet) gives an arc second of 100 feet, a "ten"th of a second of "ten" feet and a hundredth of a second is one foot. This ratio is also future proofing of DMS for better accuracy from instruments for angle observations. The pragmatic nature of DMS overcame the introduction of a shorter half fathom by English King Edward 1st after 1275 CE (yard/foot) with a shorter 5280 foot Statute mile for a 24,000 equator (it failed there) but persisted as today's foot. An English scientist commented later this gave 6068 (Edward) feet for a Nautical Mile. The DMS ratio also gives a relationship between length volume and weight for trading where a pint is 5 inches wide, 7 inches long and 1 inch deep for 35 cubic inches giving a 280 cubic inch gallon of 10 pounds Portolan maps show how well developed this triangulation mapping system had developed.over the millenia. A deep heuristic (mathematical computer) study of Portolan could only establish course books of three navigators was used make the maps called Bearings to Ports of the Mediteranean Sea. It could not establish how the map was made. The clue was in the title. "Bearings" Intersection bearing triangulation maps. This type of map started being called Plane Table mapping in the 1400'. A lattitude and longitude point establishes your angukar position on a line between the centre of the Earth and the stars. This allows a rigid angular structure for a scale map made of (bearing intersection) triangles and also give Navigatoon distances of Nautical Miles. The ephemeral nature of ancient original maps mean they only survive over ages by copying. The ancient Finaeus map that has been found shows a reasonably correct position and correct shape of an ice free Antarcticaat least 6000 years ago long before recent history found it. In Captain Cook's search for Antarctica he was able to "Plane Table" map the entire coast of New Zealad as well as the full length of continental east coast of Australia within s few maps.

The sound quality on this video was dreadful

interesting stuff. try again nothing wrong no ones perfect. Set something up again better mic bruv try it

:D

They would have had to have help from advanced beings of some kind that could see the Earth from above. This makes the most sense regardless of how outlandish it seems.

very interesting, but Presenter needs to invest in a throat mic

they must have had some pretty fast cars back then. the guy traveled 500 miles in one day to finish his experiment. what kind of car did Jesus drive?

The world is round, but as a plane and not a ball!

They must of had helicopters back in AD. It just don't make sense

Oh okay, so we praise them on their mapping skills, remarkable I heard, but slam them on their belief that the world is flat!? tisk tisk.

Learn to use the microphone properly.

Nothing but Lies conveyed as truth.

you prove that the earth is flat.

Bullshit,it Never takes that long to tell the truth...!

earth is flat

It is said that the sound guy never got another job after this one...

Go back to your sleep

they invented them, is the simple answer. Sicks years ago all maps where invented, in the beginning and for the first year there was only what looks like the northern hemisphere. One year later, that is about five years ago some new continents and their culture language and history where invented, i still remember the hillariosity when they came up with the continent of africa(a continent that is not). We are living in a crater on planet mars, that is as small as an be. We are only about 30.000 inhabitants and yaeh, thats it.

you don't know what you talking about my friend. The Earth is flat

That pic of earth is actually fake. Nasa even admit it lol

poor presentation by an American who knows nothing of the outside world....."hey these dudes seem to call this town Jidda"

Another institution that seems incapable of 'mikeing-up' a speaker! Ruined.

So? Light is holding this ball in space? Lol if it be spinning wouldn't all the water be at the equator? I don't know what it looks like,but I'm pretty dam sure it ain't a ball floating by light? Its self evident just look and think for yourself. No way they could of timed the at that distance at that time? Sounds like a scam to me,all jargon just listen,just repeating crap, dude life all life is a pole in a hole! Not two poles , and Columbus?

Really feel sorry for the world to have scientists like him. Absolutely restarted.

thy copy it from Muslims map

He still thinks he is living on a ball, LOL. I can't listen to this nonsense anymore...
