==What is 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 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.

The {{software}} uses Geo data (vector and raster data) for creating the [[3D World|3D-model world]]. For this, the {{software}} automatically connects to (Open) Datasets (see image), 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. For a whole overview of all the connected datasets, see this [[Project_Sources#Sources_connected_to_the_Tygron_Platform|table]].

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#How_to_import_Geo_Data|Geo Data Wizard]] page.
To add missing Geo data you can add additional Geo data manually (see below for options).

==When to use your own data==
==Used Datasets==
* 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 {{software}}
* 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 by the user.
 
==Which data can be uploaded to the {{software}}==
Almost all data can be imported in the {{software}}, 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|spatial plans]] can be imported in the {{software}}.
 
==How to import Geo data==
There are different methods for importing Geo Data.The method to choose is based on how you have your data available, as vector or raster data.
 
====Vector====
With the [[Geo_Data_Wizard|Geo data wizard]] you can easily import vector data. The wizard also helps you to transform your data to the proper format for importing. The following requirements for vector data apply:
# Geo Data in the {{software}} are always polygons. Line and point features are not allowed by the {{software}}. The data 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.
There are different import methods. 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 different methods are:
# with a [[GeoJSON]] file
# through a [[WFS|Web Feature Service (WFS)]]
# through a [[CSW|Catalogue Service for the Web (CSW)]]
 
====Raster====
# through a [[WMS|Web Map Service (WMS)]].
# as a [[Geotiff_(Overlay)|Geotiff overlay]]
 
==How to export Geo data==
====Export vector data====
The components that make up the 3D world can be exported as 2D vector data in [[GeoJSON]] format. With these data, further/other calculations or analysis can be done in for example GIS software.
In the Current Situation tab, each of the following menus has an export GeoJSON option:
*[[Buildings]]
*[[Terrains]]
*[[Neighborhoods]]
*[[Zoning]]
*[[Plots]]
*[[Areas]]
*[[Network]]

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 {{software}} provides an overview of the used Geo Datasets in the [[Project_Sources|Project Sources]] overview.

In the Export Item File panel that will show up, different options for exporting are available:
{| class="wikitable"
* Objects from a certain category/type (only for the [[Buildings]] and [[Terrain|Terrains]] can be exported by selecting the desired category/type).  
|-
* Only objects that have a certain attribute can be exported by checking the ''With Attribute'' option and selecting the desired attribute. For example if you only want [[Culvert_(Water_Overlay)|culverts]], you can select the category ''Underground'' (since the function culverts belongs to the category Underground) and check the ''With Attribute'' option and select the attribute name ''CULVERT_DIAMETER'' for example. This will export culverts, since only these objects have this attribute in common.

[[Grid_Overlay|Grid overlays]] can be exported as a GeoTIFF or ASCII file. With the GeoTIFF file, calculations from for example the [[Water_Overlay|Water overlay]] can be exported to be further processed for analysis in GIS software. For exporting the grid overlays, take also note of the [[Grid_Overlay#Grid_size|grid size]]. The smaller the grid size, the more accurate the exported GeoTIFF is.

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

Load data from databases

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.

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.
