Great video! Only one thing so far, in 04:00, when calculating the arc of sector there is a mistake. You say that the arc is 255º (correct) but on the screen you write down 225º. I think that´s a transcription mistake. Thank you!
Hi Leo, for the video, I trace lines from a Lambert's Chart with a 45 degree POO, then measure it using a protractor. You can use a formula for Lambert's conformal Convergence Conv = CHLong × Sine POO
@@AnsweringATPL sinus parallel of origin = constant of cone as stated on Video 13:57 but you maybe forget to mention a constant of cone value is 0.7071....with that constant value of 0.7071 degree now is easier to understand what you have mentioned in Video 12:25.... For changed of longtitude 30 degree at Any Latitude is convergence @chart always constant as 0.7071 x 30 degree = 21.2 degree.... Thanks for reply and explanation.... 👍
The modification you said that Lambert made to the projection does not by itself make the projection conformal. If moving the cone down is the only change that is made, this is equivalent to scaling the cone with the light source as a fixed point, and this in turn will have the effect that the entire map projection is scaled. However, scaling alone cannot change the conformality of a map projection. Therefore, there must have been some other modification that Lambert made to the simple conic projection in addition to moving the cone that made it conformal.
If you have comments, suggestions, or questions, please leave them here. I will try to reply to all comments. Thank you
One stop shop for learning Lambert basics -- right here in 18 minutes. Great job! And thank you for existing!
The best ever explanation. Flawless delivery and pace. Treat to listen. Keep it up. It cannot be better then this
thnk you so much. really searching for a graphical video. couldnt visualize myself. now i understood .
great video! probably the best out there!
Glad you think so!
Very nice explanation.
Thanks

Well done sir
Very helpful ❤️
Good Day Sir, on Video 12:25 convergence on chart is also 21.2 degree. How you calculate this or which formula you have used? Thanks for this video

Sorry, I should update my explanation. Tq for your recommendation

please make video on every chapter
