GIS Functionality in 3D Repo
The aim of this article is to get you familiar with the GIS functionality in 3D Repo. You will learn how to:
- Set up maps with GIS and project base point
- Load various map tiles of different styles and functionalities
- Geolocate your project
- Load alternative GIS information to 3D Repo
Set up GIS Maps
- Log in to 3D Repo with your username and password credentials
- Go to your Teamspace and open any 3D model you’d like to link with map tiles
- Head over to the GIS card by clicking on the GIS icon
If you are not familiar with the steps above, please visit our Getting Started guidance on 3D Repo.
GIS Settings: GIS Point
Correspond to the Latitude and Longitude. These are the units that represent the coordinates at the geographic coordinate system.
You can find out where your project fits based on the name of the place, city, address or postcode.
Use your own GIS data or query the longitude & latitude information from the likes of Google Maps or OpenStreetMap.
Angle from North
You can adjust your project rotation based on a specific angle.
This corresponds to the true North which you can assign from ‘Angle from North’.
Note that the angle is in clockwise degrees.
GIS Settings: Project Base Point
Correspond to the orthographic projection of your model in its GIS Location.
Essentially it is the X, Y, Z point in your 3D Model that sits in the same location as Latitude & Longitude.
Here we will show you how quick and easy it is to locate the GIS maps in your model.
In this example, I know where our model is located (Moor Place, Finsbury, London, United Kingdom)
Our first step is to pick a model location that we will use as a Model Coordinates.
To do this we are going to use the Measurements Card (see our video tutorial on how to use it)
In this case, it will be the corner of a building as shown below:
X = 83301300
Y = 36342420
Z = 113569
Our next step is to find out what is the Latitude and Longitude of this location.
We have located the same corner of the building using Open Street Maps, you can even use Google Maps.
Now we can use this information to specify our World Coordinates.
Open Street Map
All that’s left to do is copy the information gathered and paste it in the required fields and click the save button*
*Please note that in this instance I had to use – for our Z(mm) value.
If your model is offset from 0 like in this instance it is 113569mm, you need to reflect that in the GIS Settings.
If your Z value is:
- > 0 then add a minus before it (ex. 1500 should be -1500)
- = 0 then use the original number (ex. 0 should be 0)
- < 0 then remove the minus before it (ex. -1500 should be 1500)
Here is how it looks once we have matched our Model Coordinates with the World Coordinates
Map Style Options
By default, you get access to the ‘Open Street Map’ style.
You’ll need to upgrade your 3D Repo license if you wish to have access to other various styles.
Each map style is a representation of a geographic feature and encapsulates different layers which can be visualised together.
Here are some examples of available map styles in 3D Repo:
Usually presents elevation (contour lines) and relief levels.
If your model fits in an urban context, this corresponds to the road networks and building fabric as map tiles.
This is the aerial imagery captured from satellites.
Gives you an overlay of the transport map which includes Tube & Rail lines for example.
Click on the eye icon next to Map Tiles to Load or Unload the map tiles.
GIS Settings by clicking on the ‘Settings’ icon, you can modify the project coordinates again.
You can add Live information feed to any of the map styles and that includes:
- Traffic Flow
Tracks live traffic feed, red indicates the most congested area whereas green is the least congested.
- Truck restrictions
Route planning considering truck attributes and restrictions such as weight restrictions on bridges, height restrictions in tunnels.
- Try overlapping both functionalities:
There are additional map styles such as:
- Hybrid style
- Toll zones (for congestion charges)
- Landmarks & Points of interests (POI)
Query any model location by dropping a pin where you need to take a measurement.
Examples of Alternative GIS Information: Uploading Models as GIS Type
Instead of using the existing GIS feature, you may wish to upload your data such as:
- Textured .FBX or .OBJ models
- Meshed Point Cloud models
- Meshed Photogrammetry Surveys
- Head over to your project and select ‘Model’ to create a new model
- Fill in the input fields accordingly and make sure you select GIS under the drop-down options in ‘Model Type’
- Upload the model you wish to use as a map by clicking on Upload file icon
- Fill in the corresponding input fields then click Select File
- Hit Upload when done
- You can always review the model settings by clicking on the settings icon in your Model’s card
- A Model Settings window will appear where you can review the settings
- Your 3D map is now available online as a model!
