Fontus Technology

Modeling technology

Fontus technology and process knowledge enable cost efficient and intelligent 3D Maps for Internet and Wireless Applications.

Fontus key technology is its DDL (District Description Language) an object-oriented architecture, which provides conceptual as well as geometrical representations of the environment. This makes Fontus models eminently suitable for developing many kinds of software with modern object oriented tools and methods.



Fontus knows how to make traditional 2D-digital maps into modern 3D-digital maps and how to administer and deliver these maps of the future. Fontus provides state-of-the-art 3D visualization for personal navigation applications and other location-based services.

Products and know-how

Fontus has unique knowledge of the 3D modeling process for large areas and its personnel have developed a technology that allows for mapping a city in a lightweight object oriented vector-based model.

- the technology and Fontus process knowledge enable cost-effective creation of 3D maps

- the technology enables visualization of 3D maps to small-screen devices due to the scalability to match minimal processing capacity, memory requirement and bandwidth, and is optimal for use in personal mobile navigation services.

Existing products prove that the company has the ability to develop 3D maps for web browsers and wireless devices and software solutions for 3D mapping process.

Core Competence Areas

The mapping knowledge is based on two corner stones:

The process of creating 3D models of very large existing districts cost-efficiently

End-to-end knowledge in the documented process and tools to make 3D models from aerial photos or existing digital maps - this is a complex process with several dozens of steps and it has constantly been improved for 8 years.

- Incremental steps from low cost and low fidelity modeling of the rural areas to high detail modeling of the city centers.

- Extensive experience in using powerful Fontus-developed building and facade editors to model intelligent buildings fully in 3D.

Fontus personnel have explored various sources of mapping data (aerial photography, laser scaling, digital photogrammetry and GIS) to find optimal manners to utilize the variable data sources.

Optimizing the format and delivery of the model

Fontus has deep knowledge in object oriented modeling. This means that Fontus' object models generate the best data format with optimal amount of details for different bandwidths and Internet clients.

The Fontus Object Class Architecture has been designed for generality. This means easy conversion to any documented 3D, CAD or GIS format

There is an incrementally controllable level of fidelity and the order in which details are added is based on their contribution to recognizability.

The technology for mobile Internet has been tested in two lead markets for mobile Internet: Finland and Japan

Characteristics of Fontus Technology and 3D Models

- Fontus' advanced model architecture is an optimal platform for creating applications that require narrow bandwidth and light processing power.

- Platform is suitable for any intelligent applications for GIS, media, mobile services and personal navigation.

- Compactness of Fontus' models is extremely important when deploying models over the Internet. Models are described by their geometrical properties. In Fontus' database, the facades and other objects are described by their geometrical properties and not by their photographic appearance. A facade is described by a set of lines and points, which form polygons, which form objects. The model is infinitely scalable, and the size of the model in bytes is only 1-5% of the size of a photographic model and the model does not get grainy like the photographic models as you get near.

- Fontus models have a scalable level of detail, which is ideal for applying the 3D maps in narrow bandwidth and light processing power environments, such as 3G handsets. Using the object oriented modeling technology for each class of objects, you can create rules by which the object can be simplified by software. For a window object, you can write software that combines adjacent windowpanes to simplify the structure. For a tree, you can write software that reduces the number of branches and leaves and increases the size of the leaves correspondingly. So Fontus can use software to control the level of details when the model is used. It is possible to make the level of detail fit any platform, and this scalability improves the readability of the 3D map.

- The generality of Fontus object model makes it easy to create conversion programs from Fontus models to any documented CAD and 3D format. Object orientation adds classification i.e. the model knows which polygons form a house and a window etc. This information allows versatile use of the models.
