==What is a spatial plan==
A spatial plan is a design of an area with focus on the landscape, environment, routing, the interaction between public and private space, buildings forms, materialization and more.

The {{software}} can be used for importing spatial plans in the {{software}} to evaluate certain design measures in a plan, for example if the parking standard is feasible. Depending on the use case of importing the spatial plan, there are some things to be taken into account:
In principle every spatial plan can be imported, as long as the original format of the drawing can be converted to any of the supported file formats. Take into account that the level of detail in the {{software}} does not include interior designs.
* If the purpose is to create a 3D model of a 2D- drawing, remember that the level of detail in the {{software}} is not that detailed. Therefore, if the plan is very detailed, the design might not be distinguishable in the {{software}}.
* If the purpose is creating a visualization of the plan, sometimes it may be better to use placeholders for buildings, to emphasize the design phase in the project.
 
Most of the spatial plans are being drawn in a CAD program such as AutoCAD (AutoCAD Map 3D, AutoCAD Architecture) or MicroStation. Therefore, below read more steps provided to convert a plan from a CAD file to a [[GeoJSON]] for importing the plan to the {{software}}.

* Closed objects: CAD files are line drawings, while the {{software}} can only import polygons. Therefore, in your CAD file, make closed objects to be able to convert them to polygons later.
* Geometries: Features from a spatial plan are required to have a geometry to define its spatial shape and location.  
* Coordinate system: Choose a coordinate reference system for your drawing and draw and scale the plan on the right location on the planet. The most used coordinate system in the Netherlands is Amersfoort/RD New (EPSG:28992).

Without a correct location, the drawing could be anywhere on the planet and not possible to import in any spatial software on the right location.
* Layer naming: In a CAD program you draw in one or more layers. Try to draw the different types of objects each in a new layer and give the layer the correct name for the object. For example: offices are drawn in the layer offices, while student houses are drawn in the layer student houses. This will help you with knowing what each object was while converting and later on to import the data correctly in the {{software}}.
* Layer naming: Features can be grouped together in layers. For example: offices are drawn in the layer offices, while student houses are drawn in the layer student houses. The layer name can be used for classification.
 
* Attributes: Attributes can also be assigned to Features, optionally with a specific value. These can be used for classification.

The first step is to convert the CAD drawing to polygons and saving this file as a Shapefile (.shp). This can be done in AutoCAD Map 3D, if you have another CAD program or if this is not possible, save the CAD file instead as a .dxf file (AutoCAD 2013 version).
 
[[File:Specify_layer.JPG|thumb|400px|right|Choose a coordinate reference system in QGIS]]
Now the .dxf or .shp file can be opened in a GIS (Geographical Information System). In this example QGIS is used. The .dxf/.shp file can be opened by dragging the file in QGIS.
QGIS prompt to choose a Coordinate Reference System (CRS). Choose the coordinate system that is being used for the spatial plan. In the Netherlands, this is probably always Amersfoort/RD New (EPSG:28992).
[[File:Layers.JPG|thumb|400px|right|Layer panel in QGIS]]
If you have a .dxf file, QGIS asks which layers you want to open. Choose Select All en click Ok.
There are then four layers added to QGIS:
* a Point layer, which consists of the text elements
* a LineString layer which contains the layers in the CAD file
* a Polygon layer, which contains the hatches in the CAD file
* a GeometryCollection layer, which contains the references for symbols used in the CAD drawing


The layer you probably need is the line layer. This layer can be [[GeoJSON#Saving|saved as a GeoJSON]].

* Place the spatial plan in one or more measures. When placing it in multiple measures you must make sure the measures are not overlapping spatially, because that will prevent you from activating the measures all at once.

By doing so, it is possible to carry out the constructing of the plan as one [[Action]], instead of multiple actions. This will also allow the user to compare the current situation of the area with the new situation, after the spatial plan is built.

To import the spatial plan as a [[Measures|measure]], open the [[Geo Data Wizard]] and choose import as a measure. After completing the wizard, the newly created [[Measures|measure]] can be found in the [[Measures#Editing_general_measure_properties|measure left panel]].

This will allow the user to see the effects of the new plan directly on the [[Indicators]] and [[Overlay]]s, but it is not possible to compare it with the original situation of how it was before the plan was built. Also, when this option is chosen and the new plan is built, it is not possible to go back to the original situation. It might be helpfull to save the project as a new version before trying this option. To import the plan directly, open the [[Geo Data Wizard]] and choose for importing as Buildings.  After completing the wizard, the plan is directly build.

A spatial plan is a design of an area with focus on the landscape, environment, routing, the interaction between public and private space, buildings forms, materialization and more. This design can be made for an urban area as part of an urban planning project or for a more rural area for a landscape design or land art project. Spatial plans are created by urban designers or landscape architects and can have different scales and therefore different level of detail.

The Tygron Platform can be used for importing spatial plans to evaluate certain design measures in a plan, for example if the parking standard is feasible.

Requirements on a spatial plan

In principle every spatial plan can be imported, as long as the original format of the drawing can be converted to any of the supported file formats. Take into account that the level of detail in the Tygron Platform does not include interior designs.

There are some requirements on a the spatial plan before importing it into the Tygron Platform.

  • Geometries: Features from a spatial plan are required to have a geometry to define its spatial shape and location.
  • Coordinate system: Choose a coordinate reference system for your drawing and draw and scale the plan on the right location on the planet. The most used coordinate system in the Netherlands is Amersfoort/RD New (EPSG:28992). Without a correct location, the drawing could be anywhere on the planet and not possible to import in any spatial software on the right location.
  • Layer naming: Features can be grouped together in layers. For example: offices are drawn in the layer offices, while student houses are drawn in the layer student houses. The layer name can be used for classification.
  • Attributes: Attributes can also be assigned to Features, optionally with a specific value. These can be used for classification.

How to import a spatial plan

When you want a spatial plan to be implemented in your project, you basically have two options:

  • Import the spatial plan directly into the current state of your project. You will be able to perform calculations for this project, but will not be able to revert back to the previous situation unless you revert back to a previously saved Project Version.
  • Place the spatial plan in one or more measures. When placing it in multiple measures you must make sure the measures are not overlapping spatially, because that will prevent you from activating the measures all at once.
