Geo Data
What are Geo data
Geographical data or geo data are data which have a location component. Almost all data are 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 are either vectors (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 data relate to the Tygron Platform
The Tygron Platform uses geo data (vectors and raster) for creating the 3D-model world. For this, the Tygron Platform automatically connects to (Open) Datasets, such as the Base Registers in the Netherlands and Open Street Maps worldwide. A principle that generally applies: if your 3D World lacks certain information, then it is not available in the used dataset.
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 on how to import additional data is provided on the Geo Data Wizard page.
When to use your own data
You need the Data Wizard when you want to import data in the Tygron Platform. This may be for a number of reasons:
- 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 extendend 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, data in the Tygron Platform can be overwritten or supplemented by the user.
Which data can be uploaded to the Tygron Platform
Almost all data can be imported in the Tygron Platform, as long as the data is about a specific location and has a geometry. Thus basically when the data is geo data. This means that also spatial plans can be imported in the Tygron Platform.
Requirements on Geo Data
There are several requirements for loading in Geo data. The Data Wizard helps you to transform your data to the proper format for importing.
- Geo Data in the Tygron Platform are always polygons. Line and point features are not allowed by the Tygron Platform. The wizards helps you by buffering the line and point features to polygons.
- All desired attributes must be numerical, so that they can be loaded as valid attribute values. Non-numeric attributes are ignored when attempting to load them as attributes.
How to import Geo Data
There are three methods for importing Geo Data in the data wizard. These methods can be divided into two: uploading data from a file to the Tygron Platform and the other is downloading data through an URL to the Tygron Platform.
- Through a GeoJSON file
- Through a Web Feature Service (WFS)
- Through a Catalogue Service for the Web (CSW)
The method to choose is based on how you have your data available.
- It is also possible to import a Web Map Service (WMS). Read the section how to import data from a WMS.
- Geotiff
Used Datasets
The table below contains the datasets that are automatically accessed when selecting a location within The Netherlands while creating a new project. When selecting a location outside The Netherlands it is more likely that some Geo Data should be provided manually. Furthermore, the Tygron Platform provides an overview of the used Geo Datasets in the Project Sources overview.
