Internet Mapping with Geoserver, Postgres, and Openlayers 3 review for 2025
In our review of this course, we try to help you answer all of your most important questions about Internet Mapping with Geoserver, Postgres, and Openlayers 3 as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.
Feel free to jump to whatever question you want answered the most.
Here’s what you’ll learn:
Why use IMWGPAO3 as an abbreviation of the course name?
During our Internet Mapping with Geoserver, Postgres, and Openlayers 3 course review, you might sometimes see us refer to it as IMWGPAO3 for the following 2 reasons:
- We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
- We’re lazy and IMWGPAO3 is simpler and easier for reviewing purposes
The full course name is 59 characters long, including blanks, while IMWGPAO3 is 8 characters long.
You do the math.
Okay, we’ll do the math. We’re saving 51 characters every time we use IMWGPAO3.
So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to IMWGPAO3 throughout the remainder of this review.
Is the Internet Mapping with Geoserver, Postgres, and Openlayers 3 course for you?
To determine whether Arthur Lembo’s Udemy course is a good fit for you or not, ask yourself the following questions down below.
The more you answer “yes” to each question, the more likely it is that you’ll like this course.
Can you understand what Arthur Lembo’s course is about in 30 seconds or less?
Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that Arthur Lembo chose for the course, “Internet Mapping with Geoserver, Postgres, and Openlayers 3”, as well as its subtitle: “Create your first Internet Map Server application using Open Source GIS tools this weekend”.
This combo of title and subtitle should be enough to communicate the purpose of the training if Arthur Lembo is a good, clear communicator (which, of course, you want in a teacher).
In our opinion, if you still don’t know what IMWGPAO3 is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.
Among other things, it means Arthur Lembo hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.
For similar reasons, it’s important that you’re able to clearly understand what Internet Mapping with Geoserver, Postgres, and Openlayers 3 is all about from the first few lines of the course description.
So take just a few seconds to read the opening lines down below and see what you think of them.
Opening lines of Arthur Lembo’s official description of IMWGPAO3
Do you want to learn how to build an Internet Map Server application using free and open source GIS? Do you want that server to display raster, vector and attribute information and perform spatial analysis and database queries over the Internet? Do you want to learn how to connect your map server to Postgres and PostGIS. If so, this course is for you. I will walk you step-by-step through the process of installing Geoserver, loading data, creating server side analytical processes, and finally show you how to render the data on the client side using Openlayers 3.0. Don’t be afraid – this is a painless step-by-step approach that anyone can learn with my course.
When you are done with this course, you’ll have the basics down. Now it’s up to you to create impressive Internet mapping sites!
See you in the course!
(Read more about this course on the official course page.)
Does IMWGPAO3 pass the 30 Seconds Test?
You can read a lot more about Internet Mapping with Geoserver, Postgres, and Openlayers 3 on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?
If so, Arthur Lembo has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.
And, if not, maybe you’re better off looking at other IT & Software classes that are more clearly defined and more tailored to your specific interests.
Did Internet Mapping with Geoserver, Postgres, and Openlayers 3 appeal to you in 30 seconds or less?
Now that you’ve done the 30 Second Test with IMWGPAO3 above, what is your gut reaction to this IT & Software course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?
Did Arthur Lembo do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?
If so, Arthur Lembo’s online course is certainly worth considering some more.
But if not, perhaps it’s in your best interest to consider some other IT & Software courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.
Does Arthur Lembo sound like a course instructor you’d like to learn from?
You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the IMWGPAO3 course is worth taking.
We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, Arthur Lembo’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.
There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.
(FYI, all Udemy instructors, including Arthur Lembo, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).
Opening lines from Arthur Lembo’s Udemy bio
Dr. Arthur J. Lembo, Jr. is an educator with a passion for GIS and almost 30 years of GIS industry experience. He has won numerous teaching awards, including the prestigious New York State Chancellors award for Excellence in Teaching (2006), and the Maryland Board of Regents Teaching Award (2018) – both of these awards are the highest awards in academia for both States.
(Learn more about this instructor on the official course page.)
What did you think about Arthur Lembo after reading just the first few lines of the bio above?
After reading just the first few lines about Arthur Lembo, did it make you more or less interested in taking the IMWGPAO3 course?
And did it make you feel like Arthur Lembo was more or less credible and qualified to teach Internet Mapping with Geoserver, Postgres, and Openlayers 3?
Finally, overall, did you feel like you’d receive the proper training from the instructor of this IT & Software course?
As always, we encourage you to listen to your gut instinct, which is different for every student.
Are the IMWGPAO3 lessons clear, specific, and organized well?
Part of the (good) problem with Udemy’s online courses, such as the Internet Mapping with Geoserver, Postgres, and Openlayers 3 course, is that the instructors are constantly updating them, including adding and renaming lessons.
So it makes no sense whatsoever for us to list out all the modules and lessons in the IMWGPAO3 course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.
We do, however, have some tips about reviewing Arthur Lembo’s course structure, so that you can get a better sense of whether this program is worth your time or not.
In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Internet Mapping with Geoserver, Postgres, and Openlayers 3, as well as the course’s subtitle, Create your first Internet Map Server application using Open Source GIS tools this weekend.
If the section names and lessons are clear, specific, and relevant, then it’s a good sign that IMWGPAO3 is potentially a good, useful course for you, and you can have more confidence in Arthur Lembo’s teaching abilities and lesson planning.
On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.
Have you taken some free lessons from Arthur Lembo that you enjoyed?
Have you already learned something from Arthur Lembo that you valued or enjoyed?
For example, does the Internet Mapping with Geoserver, Postgres, and Openlayers 3 training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)
But if you weren’t able to get any IMWGPAO3 lessons for free, have you perhaps watched a YouTube video by Arthur Lembo, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?
Or have you perhaps even taken one of Arthur Lembo’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)
In any case, the more familiar you are with Arthur Lembo’s teaching methods, and the more you enjoy them, the more likely it is that Internet Mapping with Geoserver, Postgres, and Openlayers 3 will be a good fit for you.
(P.S.: We strongly encourage you to seek out some free instruction from Arthur Lembo before purchasing this course, since it’s one of the best ways to determine whether IMWGPAO3 will be helpful for you.)
Are “Internet Mapping with Geoserver, Postgres, and Openlayers 3” reviews generally positive?
On the bottom of the IMWGPAO3 page, you can read student reviews of the class.
Prior to August 25, 2025, there were 1,426 students enrolled, 533 reviews / ratings, and it was overall rated 4.3 out of 5.
Obviously, the more highly other students rate IMWGPAO3 the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.
After all, everyone’s got their own opinion.
We recommend that you spend only a couple minutes scanning the IMWGPAO3 reviews to get an overall sense of them. You don’t have to read each one!
Is Arthur Lembo responsive to student questions in the IMWGPAO3 training?
You can see what other students have to say about this in their IMWGPAO3 reviews.
But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.
In this case, Udemy has a messaging system for students / anyone who has an account, and you can send Arthur Lembo a message through this system quite easily, even if you haven’t bought IMWGPAO3 yet.
For example, you could say, “Hi, and I came across IMWGPAO3 while looking at IT & Software courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”
If you use this approach, the response (or lack of response) from the professor will tell you everything.
Obviously, the quicker the response the better!
Are you comfortable going through the lessons in Internet Mapping with Geoserver, Postgres, and Openlayers 3 on your own, online?
This is a big one, because Internet Mapping with Geoserver, Postgres, and Openlayers 3 is an online course as opposed to a course that you physically take in a classroom.
Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Internet Mapping with Geoserver, Postgres, and Openlayers 3.
Yes, you will be able to interact with the students and the teacher, Arthur Lembo, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.
This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.
Do the pros / benefits of IMWGPAO3 make it worth your time?
Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Internet Mapping with Geoserver, Postgres, and Openlayers 3 training that looks something like this:
- The purpose of IMWGPAO3 can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
- Arthur Lembo is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
- Other IMWGPAO3 students have great things to say about the program
Other benefits include:
- You get to go through IMWGPAO3 at your own pace
- You join a community of 1,426 other students taking the course
- You get lifetime access to the training
- All updates to the training are free
- You have a 30 day money back guarantee
Even if there are some things that you don’t like about the program, so what?
The question is simply this: do you think that IMWGPAO3 would be worth your time, even if there are some things that could be better about it?
Can you comfortably afford IMWGPAO3?
Can you comfortably afford the cost of Internet Mapping with Geoserver, Postgres, and Openlayers 3?
This is an important question to answer, because even if you think IMWGPAO3 sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!
Before August 25, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.
Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on IMWGPAO3 with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.
We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.
How can you maximize your discount on Internet Mapping with Geoserver, Postgres, and Openlayers 3?
By far, the easiest way to get the best and biggest discount on this course is to use the Internet Mapping with Geoserver, Postgres, and Openlayers 3 discount code link at the top of this page.
It will instantly give you the best coupon code we could find for Arthur Lembo’s online training.
We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best IMWGPAO3 course coupons and promo codes you can find.
FYI, the methods below will help you not just with getting IMWGPAO3 for a better price, but also with any other Arthur Lembo Udemy course that you’d like to get for cheaper.
How can Google help you get a IMWGPAO3 discount?
To use this method, do a Google search for the IMWGPAO3 training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.
For example, you might do a search for “Udemy Internet Mapping with Geoserver, Postgres, and Openlayers 3 promo code” or “Internet Mapping with Geoserver, Postgres, and Openlayers 3 udemy coupon codes” and see what turns up.
Similarly, you can use the same combination of search terms with Arthur Lembo’s name and see what happens.
For example, you might do a Google search for “Arthur Lembo Udemy coupons” or “Arthur Lembo course coupon codes” and see if that helps you.
However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.
So in this case, for example, prioritize searches for “Internet Mapping with Geoserver, Postgres, and Openlayers 3 coupons” rather than “Arthur Lembo coupons”.
How can a Udemy sale get you IMWGPAO3 for cheaper?
Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.
So, if you’re interested in saving as much money as possible, you could wait and see if you can get IMWGPAO3 for this cheaper Udemy sale price one day.
The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if Arthur Lembo decides not to participate in the site wide sale, then you won’t get a discount on IMWGPAO3, even though you could get a great discount on almost any other class at Udemy!
To understand this, think of there as being two different coupon categories for the IMWGPAO3 course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.
At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.
How can you get a IMWGPAO3 discount from Arthur Lembo?
If you’re really serious about getting “Internet Mapping with Geoserver, Postgres, and Openlayers 3” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Arthur Lembo, instead of waiting for a Udemy sale.
To do this, you can use either the direct approach or an indirect approach to try to get your discount.
With the direct approach, the big idea is to simply get Arthur Lembo’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).
Then you send a message saying something like “I’m interested in enrolling in Internet Mapping with Geoserver, Postgres, and Openlayers 3. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)
On the other hand, with the indirect approach, you join Arthur Lembo’s mailing list, if you can find it, and then you hope that at some time IMWGPAO3 will be promoted to you at a discount.
By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.
Can you get IMWGPAO3 for free?
Of course, the best possible price for the IMWGPAO3 training is free! As in, you pay no money whatsoever.
And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that Arthur Lembo has done this.
Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.
For example, you might do a google search for “Internet Mapping with Geoserver, Postgres, and Openlayers 3 free coupon” or “Internet Mapping with Geoserver, Postgres, and Openlayers 3 100 off coupon” and see what happens.
But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.
So even Arthur Lembo has offered free coupons for IMWGPAO3 in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.
What about a IMWGPAO3 free download?
It’s important to understand that there’s a difference between getting full access to the IMWGPAO3 training for free legally with a free coupon code vs. finding a way to download IMWGPAO3 illegally.
If you really want to go the download route, you can do a google search for something like “Internet Mapping with Geoserver, Postgres, and Openlayers 3 download”.
And if that doesn’t get you the results you want, you can add the word “free” to your search.
For example, perhaps you could do a google search for “Internet Mapping with Geoserver, Postgres, and Openlayers 3 free download”.
However, even if you get some results from these searches, we do not recommend that you take this course of action.
First of all, there are some shady sites out there that could be trying to infect your computer.
Second, Arthur Lembo created this course and deserves monetary compensation for it.
And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 1,426 students enrolled in the program.
Can you get a refund on Internet Mapping with Geoserver, Postgres, and Openlayers 3 if you don’t like it?
Let’s say that you used our tips above, and you were able to buy the IMWGPAO3 training at a fantastic discounted price. So at this point, you’re super excited.
Then, you actually dive into Arthur Lembo’s course, and you discover that it just isn’t for you for whatever reason.
And now you’re super bummed, because you feel like it wasn’t money well spent.
Well, guess what?
Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on IMWGPAO3 no matter what. And this means there is absolutely no risk.
Indeed, even if you left a super negative, critical review on the IMWGPAO3 training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing Arthur Lembo could do about it, since it is simply Udemy policy.
To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing IMWGPAO3 and not liking it, since you can always get your money back.
What is OCP’s overall rating of Internet Mapping with Geoserver, Postgres, and Openlayers 3?
During this IMWGPAO3 review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.
So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.
Anyway, after taking a look at the IMWGPAO3 training, the instructor, Arthur Lembo, and reading what other students have said about this program, we give it an overall rating of 4.8 out of 5.
Ultimately, though, what matters most is what you would rate it based on the same criteria.
