Arika Ligmann-ZielinskaGUEST
2:48
At that time, I had to draw maps by hand.
Arika Ligmann-ZielinskaGUEST
2:52
GIS was pretty nascent and we didn't really have that much exposure to GIS.
Arika Ligmann-ZielinskaGUEST
2:59
That was a good experience because it was very, very time consuming.
Arika Ligmann-ZielinskaGUEST
3:03
So you had to be patient.
Arika Ligmann-ZielinskaGUEST
3:49
And a lot of the stuff that I learned then, I actually repeated learning when I was doing my PhD.
Arika Ligmann-ZielinskaGUEST
3:57
So that was actually very novel.
Arika Ligmann-ZielinskaGUEST
4:00
But the fact that we didn't have GIS that much, I did have some exposure.
Arika Ligmann-ZielinskaGUEST
4:05
That was a little bit of a drawback.
Paul CarrackGUEST
33:53
And the guys were, uh, they were fantastic actually.
Paul CarrackGUEST
33:56
They, on the whole, the GI, GIs were really great guys, and then they were getting like, you know...
Paul CarrackGUEST
34:01
I remember one guy who was really, really drunk and he's like, "What's up, mate?" And he was like, that he was going to Vietnam, you know, the following week.
Paul CarrackGUEST
34:09
It was all that sort of stuff.

In this episode of the Net Zero Compare podcast, I speak with Hesham Gamal Ghaffar about the practical role of digital twins in smart cities, infrastructure, construction, and sustainability.
Karol KaczmarekHOST
0:14
We look at what actually qualifies as a digital twin, how it differs from a 3D model, BMI or GIS system, and where the technology is creating real business value today.
Karol KaczmarekHOST
0:27
We also discuss how digital twins can support better decisions around energy, infrastructure, operations, and environmental performance, as well as the challenges around data quality, interoperability, implementation, and cost.
Karol KaczmarekHOST
0:44
Hesham also shares his perspective on why some digital twin projects fail, how organizations should decide how sophisticated their systems really need to be, and what AI can realistically add when the underlying data is reliable.
Karol KaczmarekHOST
1:20
everyone, and welcome to another episode of the NetZero Compare podcast.
Karol KaczmarekHOST
1:24
Today, I'm joined by Hesham Gamal Ghaffar, Manager of Digital Twin Smart Cities and AEC, which stands for Architecture, Engineering and Construction at ESRI Saudi Arabia.
Karol KaczmarekHOST
1:37
Hesham works across digital twins, geospatial technology, smart cities, construction, and infrastructure with a particular focus on connecting GIS or Geographic Information Systems, BMI or Building Information Modeling, and other data sources to improve how cities and major projects are planned, built, and operated.
Karol KaczmarekHOST
2:01
There is still a lot of confusion around what a digital twin actually is, where it creates real value, and what organizations need in place for it to be useful.
Chris GaumerGUEST
44:27
So when we looked at 2017, the data and everything we collected from 2017, we said, there's a better way to do this.
Chris GaumerGUEST
44:37
Our GIS department worked with our equalization department and we wrote using ESRI Survey 123, a survey for the residents.
Chris GaumerGUEST
44:50
And that survey had the actual definition from FEMA that said you had water that reached your mechanical systems.
Chris GaumerGUEST
44:57
You had water that got to the first floor.
Chris GaumerGUEST
45:04
So it was more clear to the people who were self-reporting what that damage looked like.
Chris GaumerGUEST
45:12
And then we would actually go and start looking at that information, that data.
Chris GaumerGUEST
45:18
And on our tablets that we had in the field with us, we could see what parcels had been looked at, the GIS tablet, through the GIS application.
Chris GaumerGUEST
45:28
We could see what parcels had been looked at.
Bridget ScanlonHOST
0:25
David is a Professor Emeritus at the Cockrell School of Engineering at UT Austin, where he taught since 1981, and he also served as Director for the Center of Water and the Environment for 14 years.
Bridget ScanlonHOST
0:39
His research focuses on surface water hydrology, and in particular, applying GIS to hydrology.
Bridget ScanlonHOST
0:47
He was elected to the National Academy of Engineering in 2016.
Bridget ScanlonHOST
0:51
So today, David, um, I hope we can focus primarily on your work related to flooding, uh, in Texas and throughout the US.

26 MINS LATER

David MaidmentGUEST
26:54
And I have to say that the work of Dave Golchert at NCAR and the WRF Hydro system that he had developed there was really instrumental in what we had done.
David MaidmentGUEST
27:03
And also of Shadrack David, who was a PhD student of mine, who developed a routing model for the river network of the country.
David MaidmentGUEST
27:11
And we put those two things together here in Austin with GIS to convert weather information on square cells into hydrology information on catchments.
David MaidmentGUEST
27:21
And we succeeded, and by November, we had a model that ran across the country, but it was really slow.
Casey DenmanHOST
8:11
Depending on your budget and the particular auction, that one step may quickly eliminate a substantial percentage of that list.
Casey DenmanHOST
8:20
And you have not even opened the property assessor's website, looked at GIS, researched the title, or anything else for that matter.
Casey DenmanHOST
8:27
You simply went down the list, you looked at a number on that list, and you determine, boom, right off the bat, that property does not fit my budget.
Casey DenmanHOST
8:36
There's no reason to waste time on it.

10 MINS LATER

Casey DenmanHOST
18:31
After that, I will look at the sales history.
Casey DenmanHOST
18:33
I'm a big fan of using prior sales data, even if the most recent sales took place 10 years ago it does not necessarily tell you what the property is worth today but it gives you a piece of useful information that is going to be right there in front of you on that assessor's report in most counties it may help you understand how the property has been treated historically and it provide at least some indication of its potential value at that time Okay, we've gone through the tax list, we've gone through the assessor's report.
Casey DenmanHOST
19:06
If the property has survived everything up to this point, I'm gonna be willing to invest a little bit more time into the property, and I'll do that by opening up the GIS mapping system for the county.
Casey DenmanHOST
19:21
Now, if the county does not have a GIS, you may need to locate a plat map and compare it to Google Maps or some other mapping source.
Daniel KligermanGUEST
0:27
So we can't avoid construction, but we can coordinate it better.
Daniel KligermanGUEST
0:31
GIS is so critical here because it can help us understand what will happen if I close these three roads at the same time.
Daniel KligermanGUEST
0:39
Or what if I split them apart? Pros and cons, right? Maybe it'll cost less if I do them at once because I can share resources.
Daniel KligermanGUEST
0:45
But what is the impact going to be on construction?
Setabria StevensCORRESPONDENT
1:06
So let's start with safety, which is the first concern for most people.
Setabria StevensCORRESPONDENT
1:11
In the US, 40,000 people die in traffic accidents every year.
Setabria StevensCORRESPONDENT
1:16
So how is GIS, or geographic information systems, being used to reduce that number?
Daniel KligermanGUEST
1:23
That's such an important question.
RobbinsHOST
7:28
His name is Aaron Padilla.
RobbinsHOST
7:29
He's a GIS specialist.
RobbinsHOST
7:31
So that's going to go along with learning a little bit more about mapping and GPS and the ways that we use those in the present day.
IshevskyHOST
7:39
Also on September 17th, it is our SPSU event, which is our word of the week.
Aidan DaoussisHOST
14:08
I'm curious how much of EarthPlus is software and how much is being the analyst your customer doesn't have?
Laura Moreno PatricioGUEST
14:16
Yeah, in the end of today, to really understand and analyze the information that it's hiding in these images, you need an AI expert, software experts, GIS experts, and Earth observation experts.
Laura Moreno PatricioGUEST
14:34
And that's the people that we have plus business.
Laura Moreno PatricioGUEST
14:39
That's why we built SPY, which is the name of our product.
Mason HerbelGUEST
10:33
But when it comes to the Azure AD Entra project specifically, They had a bunch of old Dell T320s or whatever they were, all running Windows Server 2012.
Mason HerbelGUEST
10:47
And the options were, do we do that CapEx of $30,000 or $40,000, get a bunch of servers, buy all the device CALs, user CALs, whatever, Or do we take the three softwares that run, which was like a licensing server for their GIS program, a backup script for their cloud storage, because they had already migrated everything from SMB to something called Lucid Blank.
Mason HerbelGUEST
11:17
which is mainly for creatives.
Mason HerbelGUEST
11:22
They have a Premiere Pro plug-in.
