The Geo Data Wizard
The Geo Data Wizard or in short Data Wizard is a series of steps to guide you through the process of importing Geo data in the Engine. There are several different Data Wizards which each guide you through different processes for importing Geo data in the Engine. The different wizards are for importing data as:
- Constructions (Constructions placed based on the shapes defined in the file)
- Construction values (Constructions are modified based on the attributes in the file)
- Terrain
- Neighborhoods
- Zoning (Zones placed based on the shapes defined in the file)
- Areas Areas placed based on the shapes defined in the file)
- Stakeholders
- Measures
Each of these wizards contain comparable steps which are described below.
When to use your own Data
You need the Data Wizard when you want to import own data in the Tygron Engine. 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 Engine
- 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 Engine can be overwritten or supplemented by the user.
Methods for importing Geo Data
There are three methods for importing geo data. These methods can be divided into two: uploading data from a file to the Engine and the other is downloading data through an URL to the Engine.
- Through a GeoJSON file
- Through a Web Feature Service
- Through a Catalogue Service for the Web
The method to choose is based on how you have your data available. If you have a file with data, choose the first option. Make sure you create the GeoJSON file first, if your data is in another format. If you have an URL on where dat is published according to the WFS standard, choose the second option: WFS. If you do not have data available but want to browse through an online catalogue in search for datasets or you have a data catalogue URL, choose the third option: CSW.
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 Engine are always polygons. Line and point features are not allowed by the Engine. 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.
