==When to use your own data==
{{editor location|geo import}}
You need the Data Wizard when you want to import own data in the Tygron Engine. This may be for a number of reasons:
[[File:Geo_data_wizard.JPG|thumb|350px|The Geo data wizard can be found by clicking on Geo Import in the Current Situation tab.]]
* The project takes place in a location for which there are no data sources available to create the project
{{clear}}
* 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.


==How to import Geo Data==
==Steps in the Geo Data Wizard==
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.
In the data wizards there are several steps to guide you in transforming your dataset in order to only import the relevant features in the data into the {{software}}.
# Through a [[GeoJSON]] file
# Through a [[WFS|Web Feature Service]]
# Through a [[CSW|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==
===Import method===
There are several requirements for loading in [[Geo Data]]. The Data Wizard helps you to transform your data to the proper format for importing.
There are four methods for importing Geo Data in the data wizard. These methods can be divided into two: uploading data from a file to the {{software}} and the other is downloading data through an URL to the {{software}}.
# 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.
The method to choose is based on how you have your data available:
# 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.
# Through a [[GeoJSON]] file: ''If you have a file with 2D data, choose the first option. Make sure you create the [[GeoJSON]] file first, if your data is in another format.''
# Through a [[SLPK|I3S Scene Layer Package file (SLPK)]]: ''If you have a 3D model and want to import this as a 3D model in the {{software}}, choose the second option. Make sure you create the [[SLPK]] file first, if your data is in another file format.''
# Through a [[CityGML|CityJSON/CityGML]] file: ''Although CityJSON and CityGML are two different formats, the underlying datastructure is the same. You can use this option for both file formats.
# Through a [[WFS|Web Feature Service (WFS)]]: ''If you have an URL on where data is published according to the WFS standard, choose this option: [[WFS]].''
# Through a [[CSW|Catalogue Service for the Web (CSW)]]: ''If you do not have data available but want to browse through an online catalogue in search for datasets or you have a Catalogue service URL, choose the last option: [[CSW]].''


==Steps in the Geo Data Wizard==
When selecting any of the file options, it's possible to either upload your own file, or to use a file from the [[Geo Share]].
The Geo Data Wizard is designed to minimalise the use of a GIS. In the data wizards there are several steps to guide you in transforming your dataset in order to load only the relevant features of it in the Engine.


===View===
====View====
In step 2, the data that is currently in your project in the Engine is visible. The amount of points, lines or polygons in the dataset are visible. Since only polygons are allowed in the Engine, the points and lines need to be buffered. By buffering these features, the points and lines become polygons. The buffer size is adjustable. Based on the data, choose a realistic buffer size. If your dataset contains of lines which represent roads, choose a buffer size that is realistic for the width of these roads. if your dataset contains only polygons, the buffer size is not used.

If your dataset contains of lines which represent roads, choose a buffer size that is realistic for the width of these roads. if your dataset consists of only polygons, the buffer size is not used.


===Filter===
====Filter====
In the next step you can filter the features. For example, if you have a dataset containing all sorts of roads, you can filter only the highways in this dataset. The filtering is based on Attribute name ( attribute textual value) or on Attribute value(a numerical condition). For example, if the roads have an attribute max. speed in km/h. You can filter the roads that have a max. speed of 80 or more km/h to get only the highways.

You can filter the roads that have a max. speed of 80 or more km/h to get only the highways.   


===Add or update===
====Add or update====
In this step you are asked if you either want to add data to your project or if you want to update data already in your project. This is based on the type of data and how you are adding the data. Thus as constructions or areas. If you want to import the roads dataset as functions and there are already roads in the project, updating would be a fitting option for this dataset.  
In this step you are asked whether you want to add new data or update the data already present in your project. If you want to import the roads dataset as functions while there are already roads present in the project, updating would be the way to go. <br>
For importing a [[SLPK]] file, choose if you want to Create a new building or Update existing buildings with the new model.
Create means that you delete the existing building(s) and their function(s) (which intersect with your new data) and completely replace them.
If you choose Create you get some additional steps which must be setup. You will have new options for naming, assigning Functions and assigning Stakeholders to the newly imported building.
Updating means that you are only replacing the model of existing buildings (which intersect with your new data). The new imported building will keep the function of the previous building.


===Select attributes===
====Select attributes====
As mentioned in the requirements for importing geo data in the Engine, only numerical attributes can be imported. In this screen all the attributes in the dataset are listed. The attributes that are numerical, are already checked. In the TQL Name column, you are given the option to rename your attribute.

When using the Geo Data Wizard to import [[Item]]s which has a defined type, some mapping for that type must be provided. For example for [[Building]]s and by extension [[Measure]]s, a [[Function]] must be provided. For [[Terrain]]s, a [[Terrain Type]] must be provided.
* Buildings
 
* Stakeholders
If all features in the dataset should be imported as the same type, a single type can be selected. If the dataset contains features of varying types, such as various types of buildings and roads, a mapping can be provided. The mapping will relate the presence (and optionally value) of attributes in the dataset to an intended type. This requires one or more attributes to exist in the dataset which properly indicate what types are intended for what features.
* Measures
 
Available mappings include:
 
* Mapping everything to a single type.
* Mapping features to specific types based on the presence (or value) of [[Attribute]]s in the features.
* Mapping features to specific types based on a name of a type. An [[Attribute]] is specified, and the value of that [[Attribute]] in a feature should match the name of an applicable type.
* Mapping features to [[Function]]s as defined by a [[Geo Plugin]].
 
====Assign stakeholders====
Choose the owner of the features you want to import. Also, multiple owners can be chosen, based on a mapping of attribute names or attribute values.
 
==Error messages in the Geo Data Wizard==
Errors when importing data most of the time have to do with no CRS (Coordinate Reference System) or the wrong CRS definition.
 
====No CRS defined====
"Invalid detected CRS name: null"
 
'''Error:''' This error message means that the dataset you are trying to import does not have a CRS (Coordinate Reference System) and therefore the {{software}} can't place the data on the right location. This error mostly occurs when having a GeoJSON file without a CRS property defined. <br>
'''Solution:''' Open the GeoJSON file in a GIS and save it with the correct CRS, so the property is added to the GeoJSON file. See below for the steps in QGIS.

'''Error:''' Geo data always has a location in the real world. This error message means that the dataset you are trying to import does not have a location in your project.

The Geo Data Wizard is a Configuration Wizard that is part of the Tygron Client is a series of steps to guide you through the process of importing Geo data in the Tygron Platform. It is designed to minimalise the use of a GIS for preparing the data.

Import type

There are several different Data Wizards which each guide you through different processes for importing Geo data in the Tygron Platform.
The different wizards are for importing data as:

Each of these wizards contain comparable steps which are described below. The wizard can be found by following these steps:

Editor → Current Situation (Ribbon tab) → Geo import (Ribbon bar)
The Geo data wizard can be found by clicking on Geo Import in the Current Situation tab.

Steps in the Geo Data Wizard

In the data wizards there are several steps to guide you in transforming your dataset in order to only import the relevant features in the data into the Tygron Platform.

Import method

There are four 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. The method to choose is based on how you have your data available:

  1. Through a GeoJSON file: If you have a file with 2D data, choose the first option. Make sure you create the GeoJSON file first, if your data is in another format.
  2. Through a I3S Scene Layer Package file (SLPK): If you have a 3D model and want to import this as a 3D model in the Tygron Platform, choose the second option. Make sure you create the SLPK file first, if your data is in another file format.
  3. Through a CityJSON/CityGML file: Although CityJSON and CityGML are two different formats, the underlying datastructure is the same. You can use this option for both file formats.
  4. Through a Web Feature Service (WFS): If you have an URL on where data is published according to the WFS standard, choose this option: WFS.
  5. Through a Catalogue Service for the Web (CSW): If you do not have data available but want to browse through an online catalogue in search for datasets or you have a Catalogue service URL, choose the last option: CSW.

When selecting any of the file options, it's possible to either upload your own file, or to use a file from the Geo Share.

View

In step 2, the data that is currently in your project in the Tygron Platform is visible. The amount of points, lines or polygons in the dataset are visible. Since only polygons are allowed in the Tygron Platform, the points and lines need to be buffered. By buffering these features, the points and lines become polygons. The buffer size is adjustable. Based on the data, choose a realistic buffer size. If your dataset contains of lines which represent roads, choose a buffer size that is realistic for the width of these roads. if your dataset consists of only polygons, the buffer size is not used.

Filter

In the next step you can filter the features. For example, if you have a dataset containing all sorts of roads, you can filter only the highways in this dataset. The filtering is based on Attribute name ( attribute textual value) or on Attribute value(a numerical condition). For example, if the roads have an attribute max. speed in km/h. You can filter the roads that have a max. speed of 80 or more km/h to get only the highways.

Add or update

In this step you are asked whether you want to add new data or update the data already present in your project. If you want to import the roads dataset as functions while there are already roads present in the project, updating would be the way to go.
For importing a SLPK file, choose if you want to Create a new building or Update existing buildings with the new model. Create means that you delete the existing building(s) and their function(s) (which intersect with your new data) and completely replace them. If you choose Create you get some additional steps which must be setup. You will have new options for naming, assigning Functions and assigning Stakeholders to the newly imported building. Updating means that you are only replacing the model of existing buildings (which intersect with your new data). The new imported building will keep the function of the previous building.

Select attributes

As mentioned in the requirements for importing geo data in the Tygron Platform, only numerical attributes can be imported. In this screen all the attributes in the dataset are listed. The attributes that are numerical, are already checked. In the TQL Name column, you are given the option to rename your attribute.

Name the features

If you choose to add new features, the Naming step will be visible. This step is necessary to keep track of the data you imported in the Tygron Platform. With a clever chosen name, it is easy to distinguish features from each other. There are three options for naming your features:

  1. By their file name
  2. Based on an attribute
  3. A word with a number

Assign types

When using the Geo Data Wizard to import Items which has a defined type, some mapping for that type must be provided. For example for Buildings and by extension Measures, a Function must be provided. For Terrains, a Terrain Type must be provided.

If all features in the dataset should be imported as the same type, a single type can be selected. If the dataset contains features of varying types, such as various types of buildings and roads, a mapping can be provided. The mapping will relate the presence (and optionally value) of attributes in the dataset to an intended type. This requires one or more attributes to exist in the dataset which properly indicate what types are intended for what features.

Available mappings include:

  • Mapping everything to a single type.
  • Mapping features to specific types based on the presence (or value) of Attributes in the features.
  • Mapping features to specific types based on a name of a type. An Attribute is specified, and the value of that Attribute in a feature should match the name of an applicable type.
  • Mapping features to Functions as defined by a Geo Plugin.

Assign stakeholders

Choose the owner of the features you want to import. Also, multiple owners can be chosen, based on a mapping of attribute names or attribute values.

Error messages in the Geo Data Wizard

Errors when importing data most of the time have to do with no CRS (Coordinate Reference System) or the wrong CRS definition.

No CRS defined

"Invalid detected CRS name: null"

Error: This error message means that the dataset you are trying to import does not have a CRS (Coordinate Reference System) and therefore the Tygron Platform can't place the data on the right location. This error mostly occurs when having a GeoJSON file without a CRS property defined.
Solution: Open the GeoJSON file in a GIS and save it with the correct CRS, so the property is added to the GeoJSON file. See below for the steps in QGIS.

  • Error message in the Geo data wizard

  • Open the file in QGIS and right click on the layer to choose Save as.

  • In the Save as menu, choose the right CRS the data is in. In the Netherlands, this is probably EPSG:28992 - Amersfooort/RD New

The imported data does not have a location anywhere in your project

"Detected CRS: urn:ogc:def:crs:EPSG:3857 Number of Features in this project map: 0" (or something similar)

Error: Geo data always has a location in the real world. This error message means that the dataset you are trying to import does not have a location in your project. For example if you have a project of an area in Amsterdam and you are trying to import data of neighborhoods in the Hague, you will get this error message. If you are sure that the data you are trying to import is in the same location (for example data of neighborhoods in Amsterdam into a Tygron Platform project in one of these neighborhoods in Amsterdam), the error message could also mean that the defined CRS is not correct for the data.

Solution 1: Check the box: Longitude first: In case the selected CRS is based on WGS84, the official order of coordinates is Latitude first, Longitude second. However, some software programs prefer the x-y order and export files accordingly, which means that coordinates are defined as Longitude first, Latitude second. To support both options, the Longitude First checkbox is added next to the CRS selection box.

  • Error message in the Geo data wizard when longitude first is selected. Depends on the selected server.

  • This particular service provides latitude first, then longitude, therefore uncheck the box.

Solution 2: Import data that has a location in your project or if you are sure that the data you are trying to import is in the same location, open the GeoJSON file in a GIS and save it with the correct CRS. See below for the steps in QGIS.

  • Error message in the Geo data wizard

  • Open the file in QGIS and right click on the layer to choose Save as.

  • In the Save as menu, choose the right CRS the data is in. In the Netherlands, this is probably EPSG:28992 - Amersfooort/RD New

Longitude and Latitude error

"Please check if the coordinates are correct in the original crs EPSG:4326 (Longitude first). Projection error: Latitude 483504 36.1'N is too close to a pole.

Error: This can happen when importing a dataset using the WGS84 Coordinate Reference System (EPSG:4326) and means that the data can not be correctly imported by the Tygron Platform. It can be that the dataset's coordinates are actually not WGS84, but in an other coordinate reference system that uses an alternative unit of measurement, such as meters or feet. Solution 1: Click on the Select CRS button and select a Coordinate Reference System (CRS) that you expect the data is actually defined in.

  • Latitude close to pole error shown when importing a file that have coordinates that are actually defined in a different coordinate reference system.

  • Coordinate reference system selection panel opened when clicking on the Select CRS button. A difference coordinate system is selected.

Solution 2: Open the GeoJSON file in a GIS and transform the data to a different CRS. See below for the steps in QGIS.

  • Error message in the Geo data wizard

  • Open the file in QGIS and right click on the layer to choose Save as.

  • In the Save as menu, choose a different CRS to transform the data to, for example EPSG:3857 WGS84/Pseudo Mercator
