Very good presentation.

Well presented materia.
tlgibson 2018-11-16 10:47:47

I have had some training on this subject but was still confused. This course cleared up my confusion and made sense of the different models and datums and how to go about determining what datum to select for my projects.
fischerc57 2018-10-31 12:08:35

This course provides further clarification to my geodetic studies
vmendoza 2018-09-28 13:28:32

It will definitely give you a better understanding of Vertical Datumes
JTedesco 2018-09-25 10:16:59

Good at giving basic background information! Quite helpful!
cassy.porter 2018-08-07 11:22:06

The lesson was informative but the layout was a bit confusing at times. Seemed to jump around a bit..
jcub 2018-07-18 08:24:11

great course needs more audio and video
megan.shapiro 2018-07-10 15:07:16

It would be very helpful to see more detailed results in our quiz scores- see what we answered and what the correct answer is with an explanation for the correct answer.

Very good lesson with a helpful quiz
brandygeiger 2018-04-06 17:48:48

Relvant for understanding datums and how they are used in Hydrographic Survey
adieppa 2018-03-15 20:35:05

Great lesson, although I had some knowledge my understanding increased significantly as evidenced by the final quiz.
rickolejniczak 2018-02-26 15:32:13

This is a great class for an introduction to the subject matter. Review quizzes help to reinforce learning. Highly recommended.

very helpfull
corrigan 2018-02-13 12:30:07

i wish the test would help you understand why you got it wrong vs just telling you its wrong.

Unless you have an amazing vocabulary, this it pretty complicated
ggano 2018-02-08 10:07:23

Great

Thanks

great

As an entity identified with surveying, a poll such as this one should not be called a "survey".
w.wefel 2017-12-09 22:51:15

Good comprehensive overview of height systems. The mystery of the St. Lawrence River flowing uphill is explained!
durces 2017-11-22 10:11:42

Thank you

This lesson on understanding heights and vertical datums is helpful for a broad overview of the subject, however, it might require more than once going through it to fully absorb all the material. I wish there were more examples of what the various datum systems describe since it's not so easy to see what the differences are. Also, the 18th century controversy between Newton and Cassini does not explain what methods they used to settle the question, but perhaps that is beyond the scope of this lesson.
oladotunonas 2017-10-03 10:07:44

The study is good and has the capacity to increase the knowledge of students. The lesson materials are also fixable Nad easy to understand.
vipin kumar maurya 2017-10-03 04:07:54

Very good material for concept clearance and pracice
kevin_morris@nps.gov 2017-09-27 12:55:02

Enjoyed the lesson.

I am a licensed Land Surveyor and this type of online training is very helpful to maintaining my understanding of issues related to my profession.
JonathanPrice 2017-09-21 06:28:02

Lesson may be easier to follow if more animated video explanations are done.
dmelton 2017-09-11 19:49:44

A very good introduction to the subject of datum and the difference between an ellipsoid and a geoid.
elsy-ngalaha 2017-09-10 21:10:56

Wonderful
bushasarrived 2017-08-22 18:34:19

Gives a good general understanding of vertical datums and the principals behind them

MCDitches 2017-06-23 14:17:50

This course gave me a much better understanding of heights and vertical datums.
rmorrison 2017-06-23 12:56:16

Good.
alexosfera 2017-06-02 05:30:57

I'm sure you could not imagine it!

Great overview of the intricacies involved with determining "height".
jendowe 2017-02-27 14:23:53

Very informative!
kkoeck 2017-02-26 21:25:38

A very good introduction for understanding heights and vertical datums.
joeh 2017-02-06 07:22:30

I would like to see more examples in understanding the heights and vertical datums.
jajuarez 2016-10-31 18:21:21

Nice course, for learn about heights and vertical datums
PROCSEN 2016-09-25 08:07:18

I would strongly recommend this course for all GIS oriented students. It is very good opportunity to learn new skills.
pic2 2016-09-20 16:53:10

I really appreciate the training regiments, and the opportunities to be able to utilize them, they are really great tools, and well defined educational proprieties.
ecliptico 2015-04-17 10:45:23

I liked a lot!!! thanks NGS
rolando.flores 2015-04-15 11:29:02
