Meridian Has the AGRC Solution

By News and Updates

On August 31, 2016, Utah GIS users lost their connection to the State of Utah ArcGIS networks. After many long hours of making phone calls and exerting technical genius, Meridian’s GIS Project Manager Adrian Welsh has a working alternative to help Utah GIS users access this crucial data. The following are his instructions.

How to utilize parcel data from the AGRC with ArcGIS Pro

If you have used ArcGIS Desktop (ArcMap) for utilizing Parcel data from the AGRC (Automated Geographic Reference Center), then you have probably come across this article describing the deprecation of SDE server connections (here: http://gis.utah.gov/sde-application-server-connects-deprecation/). It is past August 31, and that means the server connection is gone (for GIS users outside the State of Utah networks). While the above article goes on to show how to utilize AGRC’s GIS data from ArcGIS Online into ArcMap, this blog post will show you how to utilize this online data (particularly Parcel data) in ArcGIS Pro.

Open up ArcGIS Pro and load a new map (or use an existing one). Under the Map tab at the top, click on the Add Data button:

On the left hand side of the Add Data dialog box, look under the Portal category and choose the All Portal option:

In the search box, type in “AGRC Parcels”

Choose the newly created “Utah Statewide Parcels” Feature Layer and then click on Select:

Because there are hundreds of thousands of Parcels in the State of Utah and this layer contains them all, it is a good idea to zoom in to a specified location in order to minimize drawing time. While this is different than how it used to be (each county was once its own layer), you can now utilize the entire state at one time which is helpful when your data spans across counties.

After it is loaded, you can treat it like you would treat your regular data:

One additional note about adding ArcGIS Online data: Oftentimes it is unclear what kind of data is being displayed in the Add Data dialog box. Here is a tip on how to know what the data types are. Open the Add Data dialog box, click on All Portal in the left hand side, type in SGID (or whatever) into the search box, then click on the three lines icon at the top, and choose Gallery:

In the list of layers, now you can see what the data types are (examples include: layer, feature layer [hosted or otherwise], map image layer, layer package, tile layer [hosted or otherwise], imagery layer, etc.).

Special thanks to Matt Peters at the AGRC for getting this layer put together.

Surveyor Explores Ancient Israel, Discovers New Area

By Team Members

 

Michael Nadeau 001

Meridian’s own Mike Nadeau took the trip of a lifetime to Israel, where he surveyed on an archaeological site called Beit Lehi. He and his peers used new technology to study ancient caverns, and in the process they stumbled across some new archaeological finds that are thousands of years old.

 

Mike was responsible for flying the drone used to take aerial images and videos of the Beit Lehi site. And while the drone’s batteries recharged, he helped perform LiDAR scanning (a form of radar that uses light rather than radio waves). After interviewing Mike and hearing about his experiences, his stories are best left in his own words.

 

 

 Selfie with the drone

 

 

 

 

 

 

 

Ancient Graffiti

Drone and Controller on the Floor of Byzantine Church 2I was flying the drone from a Byzantine church on the site, dating to around 300AD. The symbolic cross of today wasn’t a symbol of Christ during the time of Christ—this came into effect around the Byzantine era, too. Something interesting that we found was a bunch of crosses and other religious symbols scratched into the rock walls everywhere. The lead archaeologist, Oren Gutfeld, PhD, told us that this was fourth-century graffiti. People would come down to the tombs or to the church and carve religious symbols into the walls. It was really interesting to know what I considered to be neat old religious carvings is considered to be graffiti.

 

 

 

Salome’s Tomb

Solames TombWe’re thinking that the Byzantine church was in the center of the city we were surveying. About a mile south is a tower foundation that they determine must be the edge of the city, and just outside the city limit was a tomb. The first morning we were there, Oren took us down to look at the tomb. It was Salome’s tomb. In the Bible, Salome is the mother of the disciples James and John. She was buried in this tomb. We saw where they would have laid her body and where they would have prepared it. This tomb had been scanned with LiDAR by previous teams, so we didn’t perform any new survey in this location.

 

 

The Quarry

Light Shining in Large Quarry we were Scanning 2The team was doing LiDAR scans in two places. The biggest LiDAR scan we did was in, for lack of a better term, a quarry. We had to climb down a 20-foot ladder into a small chamber, then crawl through a small hole inside this chamber to get into the quarry. Once we got through this hole, there were stairs that wound along the side of the wall all the way down to the floor of the quarry. You could tell that the stairs were cut—it was a quarry and they were using the rocks to build everything above ground. We were scanning this quarry and the stairs going down. There were seven big columns in the center of this quarry holding the ceiling up. It was massive. This thing was huge. We measured it from the very bottom floor to the top, and it was 67 feet.

Inside the quarry was really musty. You could almost taste the air—it was humid and smelly. At one point, I was down there for about 4 hours while we were doing the scanning and drone flights, and I had to go up to the top for some fresh air. After I got home from Israel, I had a cough that wouldn’t go away, and I think it was because of the colder, musty air mixed with the hot dry air outside our work areas. I don’t envy the guys who had to dig out this quarry.

 

 

The Condo

Condo that we Scanned with LiDARThe other area where we performed LiDAR scanning was up above a “theater room,” called the condo. I don’t know if it got its name from a big columbarium in there, where doves would sleep. A columbarium is where there are a bunch of triangles cut into the wall, and doves would go in there. There were probably tens of thousands of triangles throughout all of Beit Lehi. They would use the doves for different reasons. One, you could eat doves. Two, doves lay eggs and you could sell the eggs. Three, dove droppings make fertilizer. And four, it was a cheap sacrifice. In the Old Testament you had to have two blood sacrifices, and doves were cheaper than goats or other animals. That’s why they built these columbariums to keep doves inside.

 

 

After 2,000 Years

Something that happened while we were out there was that we were looking for this cavern to survey in, and Oren told us to wait in the vehicles while he walked around looking for the cavern above us. He hiked up to this really tall hill and we watched him walk around for about 10 minutes, and then he got really excited and yelled at us to come up and join him. It was a steep hike, and once we got up there we saw the foundation for what would have been another tower, just like the one above Salome’s tomb. These towers were built for strategic military purposes where you could see from one tower to the next, to the next and so on.

 

Opening to New Discovered ChamberThen we began walking along this path and we began noticing small stacks of rocks next to us. It turned out we were walking on a road that was 2,000 years old, and the rocks were delineating the path of the road. We could see other old roadways on the adjacent hill across the “wadi” [valley] to the west, too. It’s weird to think that we were walking on a road that people 2,000 years ago were walking on. That’s how old this road was.

 

New Discovered Chamber 2After we had been walking for a while, in this same area, we saw this hole in the ground with a ladder, and Oren got really excited. Of course we went down it, and underground there was a large chamber with a tunnel in one wall. There were smaller tunnels that branched off of it, but if you followed the main tunnel for about 200 yards, you came into this huge room. Huge. It sort of looked like another quarry, but it had more of a theater type feel. Like a place people would gather for celebrations and such. We were the first people to be in this room after almost 2,000 years.

 

 

 

 

The Sabbath

I survey all the time. You would think that I would take something from the surveying aspect, because I’m a surveyor and that’s what we do. To me, being on the site was really cool and seeing this archaeological dig was really neat. Honestly, that wasn’t what I took away from it. What I took away from it was the outside experience—it was more of a personal experience. What I took out of it was the love for the people and their land.

Dr. Oren Gutfeld from Israel Archaeological ServicesOren is Jewish, and we went to his house to partake of his “Shabbat” [Sabbath] dinner. He sang and read prayers and I really, really enjoyed this night. I would say I enjoyed that night more than anything I did on the survey site. As we gathered together, taking pictures and saying goodbye for the night, I told Oren and his wife “Toda” (thank you in Hebrew), to which he smiled and replied “Bevakasha.”

By the time I left Israel, I felt something inside of me was now a part of the Israel culture in some way. No matter how little that way is, I will always yearn to go back to the land I enjoyed for those two weeks.

Bringing It Together for the All-Together Playground

By Uncategorized

20160819_105248bPlaygrounds are notoriously complex, with twisted pathways, bars, bridges, and much more. What playgrounds are not, however, is accessible. If a child has mobility challenges, he or she is left out of the fun. Orem City recognizes this issue and is doing something about it.

Two of Meridian’s own, Darrell Flake and Kurt Falkenthal, have had the opportunity to volunteer some of their time and expertise to help in the construction of Orem’s new all-abilities playground. This playground is being constructed to offer all children, regardless of physical capabilities, a place to play.

“[Working on the playground] was rewarding,” said Falkenthal. “It felt good to give back to the community. It felt good to work with other people in the community.”

0819161123dbThe playground is being constructed with a substantial volunteer effort as well as with many donated materials. Meridian Engineering, Inc. donated the use of survey equipment and vehicles to help in facilitating the work.

“We are very community-oriented,” said Meridian Engineering’s President, Darryl Fenn. “We’re a local firm comprised of local people. We enjoy volunteering to help the community.”

The All-Together Playground is set to be completed in September 2016. Click on the link below for more information.
