Intro to coordinate systems and UTM projection (C12, V1)

[@arbazkhanpathan9259]

Its been 8 years to this video... still loved it. Thanks !!

[@2nd6months]

Thank you for presenting this. You made it easy for me to understand. I appreciate that you took the time to do this.

[@michaelm9351]

Great content, thanks for uploading! Interesting concept to work around the map projection warping issue by splitting it into small separate zones

[@motivationbynetseb]

Thank you for this simple, yet thorough video.

[@kumudsharma007]

Best ever explanation on Co ordinate systems..

[@josephlai9759]

Thank you so much for the education. Your video instruction is simply the best I have come across. Clear and precise even to newbie like my goodself.

[@johng5295]

Thanks in a million. Great content. Awesome. Very well explained. I couldn't find this explanation--simply put anywhere else. Great teachers are hard to find. Grade: A++💥

[@motivationbynetseb]

Me either. Excellent video indeed!

[@joegill3270]

Great presentation on coordinate systems and UTM projection! Thanks!

[@rchallender2493]

Great video, it was totally helpful and clear!!I'm taking an intro to GIS class at my college and I was asked this question by my professor in class today... "In a Geographic Coordinate System all properties are distorted unlike a Projected Coordinate System, why might this be the case?" I was embraced because I didn't know how to answer! If anyone with more knowledge could help me understand the answer to my professors question I would be really grateful 🙏🏻! Cheers!

[@mykleraymond3700]

Ryan, I suggest that the professors question has been written in reverse, and may have been "In a Projected Coordinate System all properties are distorted unlike a Geographic Coordinate System, why might this be the case?". A Geographic Coordinate System describes locations on a sphere (ellipse), like the globe of the earth (or any other spherical body) and the celestial sphere (astronomy). The surface of a sphere cannot be laid on a two-dimensional surface (map) without some kind of distortion(s). The definition of a Projected Coordinate System may minimize some kinds of distortion (distance, direction, area, ...) while allowing other kinds of distortion. The creator of a 2-D map must select the projection that is best suited for the area covered. Usually this will be the same projection as used for other areas. For example, surveyors in the USA will use the state plane coordinate system as defined for their area. Another example, users of topographic maps will expect adjacent map sheets to be at the same projection and scale. And everyone needs to recognize that one projection will become distorted as distances increase. In the USA, topo maps generally use the UTM projection, so you are limited to areas of hundreds of kilometers if measurement accuracy is important. If your area of interest is on the border of two UTM zones, you pick one to use for your project (depending upon your instruments, some conversions may be needed).

Fantastic job brother!!!!! Bravo

[@Syed_Tajamul_Islam]

Beautifully Explained ❤

[@seifgasim3706]

Thanks for this wonderful and informative presentation

[@petermayambwe5229]

In real it's amazing and very helpful I have appreciated it

[@jude-harrisonobidinnu3876]

Thanks for the knowledge. It's very insightful

[@richardkamwezi9297]

Thanks for this video. It puts a lot of things into perspective.

[@prasunamaskey4529]

Thankyouuu.... Loved it. So informative

[@theyoutubegamer8972]

Really great conceptul video

[@MatheusSilva-dragon]

Thanks! I really needed a quick recapp about this subject!

[@ah9337]

Thanks alot👍❤️

The reading of latitude and longitude is taken from the centre of the earth which is the intersection point of polar axis and equatorial plane (not equatorial plane and meridional plane). The longitude is a vertical angle measured in the meridional plane with reference to equatorial plane; whereas longitude is an angle measured in the equatorial plane with reference to meridional plane.

[@RUBYKINGSLY]

Hi sir can you share your what's up I have some doubts . Thank you

[@RUBYKINGSLY]

@Ram Pratap sir for example Lat = 22°42'4.7" lon 55°18'2.97" means angles measured between what points .

[@rampratap2605]

@@RUBYKINGSLY To put it simply, Latitude is an angular distance of a point on the surface of the earth North or south of equator measured at the centre of the Earth. Longitude is angular distance of a point east or west of prime meridian, measured from the centre of the Earth. Remember, Lat and Long are points. A latitude of 30 degree north is a point, but there will be infinite points of 30 degree north and if we join them we get line of 30 degree north latiyude. same with longitude. If the location of a point is given as Lat = 22°42'4.7" and lon 55°18'2.97", the lines of Lat = 22°42'4.7" and lon 55°18'2.97" intersect at that point.

[@bilbanx]

Very insightful....Thank you

[@bekeletarressa997]

Well done!

[@tubzvermeulen]

Thanks for the video

[@ADVNevada]

Great video!

[@y_p7]

thank you soooooo much you saved my life

[@JeffersonWhovianFernandes]

I'm sorry but there are a lot of mistakes in your video. Like the mistake of saying that the UTM coordinates go up to the south at 15:28, actually they go down with N = 10000 km at Equator.

[@Naruto5471]

I was wondering the same thing...

[@shapo001]

Also, the central meridian in a UTM zone is not 'touching' the cylinder, the two secant meridians are. The central meridian is above the cylinder; Earth is not a sphere, ... etc.

[@maryummurtaza4325]

its amazing sir ….. tell em about the elements of the projcted coordinate system....

[@harirao12345]

excellent!

[@billrosmus6734]

Good explanations.

[@hikikomorihachiman7491]

Could anybody teach me what’s the difference between 44R and 44N?

[@domsrequino7806]

i am confuse in to transform wgs84 to luzon 1911 system in arcgis... I cant understand how to convert.. Pls help ty

[@theplanetruth]

For those of you who aren't paying attention, the globe and its projections are concepts. There's nothing tricky about cartography if one simply sticks to reality where distance and elevation are measured. That's all anyone has: distance and elevation. How does one measure a globe? One doesn't. One measures distance and elevation and then IMPOSES a concept which then makes every thing...well, tricky.

[@hozhin]

very helpful thanks.

[@joaquinfabrega]

It was my understanding that besides numbers, the UTM zones were divided by letters from A in the South to X in the North, but I noticed you only mention North or South of the Equator. Could you please clarify this? Thanks.

[@Kerbox]

MGRS defines these latitude bands C-X, they are sometimes used instead of N/S in UTM as well.

[@joaquinfabrega]

Kim Skoglund thanks for your answer.

[@bedoor11]

Great intro! Thank you for the video :)

[@konga56]

Thank you it is helpful

[@laurenceconway8756]

Don’t mean to be pedantic but perhaps it will help; Greenwich is borough in east London, rather than a city. If you say “Greenwich , England” it sounds like a city. “Greenwich in London, England” would work

[@barandyknurdinova3530]

Thanks a lot!

[@antarachakraborty4146]

what are training sample s and reference data (GPS data)

[@greedygringoprospecting6941]

1 utm can work on all maps yes ?

[@colinrobert-kv2up]

Many. Datum. Monument control. John.

[@reza8006611]

It seems there are some mistakes! Latitude in southern hemisphere begins from 0 in south pole and increase towards north! Aslo I thing numbers for longitude doesn't start from 0 in each zone! And also are you sure projection sylider is in horizontal position?

[@meganbleess8671]

I'm unable to get the video to load past 6 minutes. 😕

[@Landoparada360]

Let me ask you a question. Let's assume that you are under Polaris, and as soon as you start walking away, measure your angle of elevation and distance between you and your starting point. Now, at what degree do you start taking into account the magnetic molten center of hell?

[@umut2243]

Just like many people including this guy dont understand coordinate systems. Only thing in the right here is people dont know meet each other.

[@WildPhotoShooter]

I guess the dislikes are the lunatic flat earth brigade.

[@artworkfats]

A wild guess?

[@konstantinparnikov3388]

I dont understand anything

[@vivageocentrism5167]

Only accurate on a flatearth map. The spinning globe curvature not considered.
