The CyberCity 3D feature is not included yet.
A CyberCity 3D layer adds low resolution 3D buildings to your map. These buildings are created by CyberCity 3D (CC3D) based on aerial photography. The buildings are lightweight but have accurate roof shapes and building shapes. They don’t have facade detail or textures. This makes them perfect for visualisations on a city scale.

CC3D has over 1.25 million buildings available in over 90 cities. Their focus is on the US, but they also have lots of buildings in Europe and other cities. Check out their coverage here. This content is available immediately. They can also create the buildings or an area of your choice on demand. Maproom lets you easily define the area you need and communicate with CC3D about that.
When you want to use CC3D buildings in a map, you can either use the CyberCity3D map preset to start a new map, or add a CyberCity3D layer to an existing map. A CC3D layer has two sections. The first section deals with the CC3D buildings you already own. The second section shows you the areas available through CC3D and it also enables you to order CC3D buildings directly.
Two sections: My CyberCity 3D models and the CyberCity 3D library
Adding buildings to a map¶
Let’s assume you already have buildings purchased and placed in the repository you can select it from the list and add them to the map by pressing the
Place selected button. As with all other map layers, an area of the data is added to your map. If you have an area of 5 by 5 km of buildings and you set the area of your map layer to 1 by 1 km, only the smaller area will be added to your map. This reduces waiting times if you only need a smaller part of your buildings as importing many buildigns takes a bit of time.
Each building is placed geographically accurate and it’s also projected in the current map projection. This means that if my map space is set to a location in London and I add buildings from New York these buildings will appear quite far away in 3dsMax. 3dsMax will not like this as it has a hard time dealing with large distances (between London and New York) and high accuracy (the 3D buildings are very accurate) at the same time. Make sure that if you’re placing New York buildings your map space is also set to New York or somewhere near.
In you’ve just ordered and received buildings from CC3D, you need to place them into your repository. To do this, press the
Open... button in the
My CyberCity 3D models section. This opens your repository. Then navigate to the
Purchased. In there you can make a new folder with a descriptive name of the area you’ve bought, for instance
Amsterdam, trainstation area. In that folder you need to make two more folders, one called
model, the other called
outline. You can unzip your models in the
model folder. The zip you’ve received from CC3D should contain two folders and a file:
dae_images (usually empty),
dae_models (contains a list of collada files, the actual 3D models) and a csv file. If you’ve received an outline, you need to put that in the folder
outline you’ve just created yourself. The outline is a shapefile which actually consists of a bunch of files, one of which has an extension
.shp. Just place all of the files you’ve gotten in this folder.
When you restart Maproom and create a CC3D map layer, your new’y added folder will appear in your models list.

The CyberCity 3D library¶
The second section of the map layer shows you the CC3D library. It contains outlines of all available building CC3D has in their library. This makes it easy to evaluate if they have buildings you can use right now in your projects. Just pick a city from the list and press
Show selected and an outline is placed in your map. You can also press
Show all to see each available area in your map.

Ordering CC3D buildings¶
You order CC3D buildings directly from them CC3D. There are two ways you can order: either order one of the available cities or order a custom area. A custom area can either be part of an existing city, a new area or a combination of both. You can specify the custom area by creating a closed shape, select it and press
Order custom area. It helps if you first create a satellite map of the area you’re interested in and then draw on top of that.
Either way, using an existing city or custom outline, the area is sent to CC3D and you’ll receive a confirmation email of your order. CC3D will further process your order and get in touch with you. They also might modify the outline of your area to avoid split buildings. Payment is also arranged directly with CC3D.
Here’s an example which shows how you can combine CC3D buildings with openstreetmap buildings and bing satellite images.
