Geographical data or geo data is data which have a location component. Almost all data is linked to a location or a place and are, therefore, geo data. Geo data can be, for example, a paper map, a digital web map or just a simple text file with coordinates. Geo datasets is either '''vector data''' (that is, features which are points, lines or polygons) or '''raster data''' (that is, data in grid cells). The features in vector data can have multiple attributes with values. Raster data mostly consist of a value and a color.


==What is GEO Data==
==How do Geo datasets relate to the {{software}}==
Geo data is Geographical information and therefor it has a location component. The information is documented in digital maps and databases. In this case the Geographic information is specified as GIS-data because of the function to attach attributes and/or objects that are assigned to a specific location. This GIS-data contains geometric charactaristics where the planes (not points and/or lines) information is stored in vectors. Additional information about the characteristics of the Geo data can be found on the [[GeoJSON]] page.

The {{software}} uses Geo data (vector and raster data) for building up a new [[project]]. For this, the {{software}} automatically connects to (Open) [[Project_Sources#Sources_connected_to_the_Tygron_Platform|Datasets]], based on the availability of the data for the chosen location of the project. For example the Base Registers in the Netherlands and Open Street Maps worldwide.

==How does GEO Data relate to the Tygron Engine?==
==When to use your own data==
The Tygron Engine uses automatically connected Geo Databases for The Netherlands to generate the [[3D World]]. When the selection is made on the map in the wizard the [[3D World]] is built up based on the available GEO Data in the connected data sources. For all the different environmental elements the database with the most complete and relevant Geo data is connected. All together this forms the [[3D World]]. For this proces the principle applies: If you miss something in your [[3D World]] it is not available in the data base otherwise it would be present in the [[3D World]]. To complete the Geo data you can either update the information in the database, or you enter additional Geo data manually. More infomation about how you can enter the data manually is also explaind on the [[GeoJSON]].
* The project takes place in a location for which there are no data sources available to create the project
* The default data sources are not accurate or up-to-date enough
* The default datasets are not detailed enough

* For creating more overview in your project, for example by highlighting areas
In these situations, it might be useful to overwrite or import data.

==When to use your own GEO Data?==
When a project is situated outside of The Netherlands only ESRI data is connected and will load automatically when the 3D world is generated. Beside water and elovation of land, this does not contain any information about constructions and/or environmental characteristics.
In [[Case_3:_Creating_a_3D_Environment_Manually_Using_GIS_Data|use case 3]] an exapmle is given of how to connect the needed Geo Data to built up a 3D environment.
It is also possible to implement your own Geo data for a project that is situated within the Netherlands but the diffrence is that this will be additional geo data instead of basic geo data in order to generate the 3D world.

Geographical data or geo data is data which have a location component. Almost all data is linked to a location or a place and are, therefore, geo data. Geo data can be, for example, a paper map, a digital web map or just a simple text file with coordinates. Geo datasets is either vector data (that is, features which are points, lines or polygons) or raster data (that is, data in grid cells). The features in vector data can have multiple attributes with values. Raster data mostly consist of a value and a color.

How do Geo datasets relate to the Tygron Platform

The Tygron Platform uses Geo data (vector and raster data) for building up a new project. For this, the Tygron Platform automatically connects to (Open) Datasets, based on the availability of the data for the chosen location of the project. For example the Base Registers in the Netherlands and Open Street Maps worldwide. A principle that generally applies: if your project lacks certain information, then it is not available in the used datasets.
For more information on which data is used for your generating your project, see the project sources page. To add missing Geo data you can add additional Geo data manually (see below for options).

When to use your own data

  • The project takes place in a location for which there are no data sources available to create the project
  • The default data sources are not accurate or up-to-date enough
  • The default datasets are not detailed enough
  • To do a more extended analysis in the Tygron Platform
  • To use in combination with an Excel Indicator or Panel
  • For creating more overview in your project, for example by highlighting areas

In these situations, it might be useful to overwrite or import data.

View Geo data

To show Geo data in other software, such as a GIS, options are:

  • the Overlays can be obtained through a WMS URL. See the WMS page for more information and steps.
  • the Buildings can be obtained through a WFS URL. See the WFS page for more information and steps.
