Geo Data
What is Geo data
Geographical data or geo data is data which has a location component. Almost all data is linked to a location or a place and is therefore geo data. Geo data is for example a paper map, a digital web map but also just a simple text file with coordinates. Geo datasets are either vector (features which are points, lines or polygons) or raster data (data in grid cells). The features in vector data can have multiple attributes with values. Raster data mostly has a value and a color.
How does Geo data relate to the Tygron Engine
The Tygron Engine uses geo data (vector and raster) for creating the 3D model world. For this, the engine automatically connects to Dutch open data sets, such as the base registers. For this process the following general principle applies: if your 3D World lacks certain information, it is not available in the database (as all available spatial information is automatically present in the 3D World). To add missing Geo data you can either update the information in the database and regenerate the 3D world, or you can add additional Geo data manually. More information about manually adding data is provided on the GeoJSON page and the page about ArcGis.
Which GEO Databases are used?
The following table contains the automatically connected data sources that are used when selecting a location in The Netherlands. When selecting a location outside The Netherlands some Geo Data has to be provided manually. Nevertheless, the overview below can give the user a good example of the type of data that can be added to a Tygron project. At the bottom of the table an integrated data source connection is mentioned. More information about his option is explained in the next topic about when to use your own Geo data.

When to use your own GEO Data?
When a project takes place outside The Netherlands only ESRI data is (automatically) used to configure a 3D world. Besides landtype (i.e. water of land) and elevation, this does not contain any information about constructions and/or environmental characteristics. Therefore it is advised to make use of additional GEO data to complement your 3D world instead of creating the 3D world from scratch. Adding additional data can be done in different ways. First of all you can add GeoJSON files. In use case 3 an example is given of the Geo Data needed to built up a 3D environment. It is also possible to implement your own additional Geo data by using the inter-grade function of ArcGis. For this function you need to have an ArcGis account or make use of available open data.
