GIS Import JSON Schema Documentation

Use the json schema files to validate your geojson files you intend to import into an AND project file.

Version

V 0.8 - 10.4.2025

File Names

The file names to be processed by import are mandatory. They should be within one folder or zip file.

GeoJSON File Description

For a description of the possible content of the GeoJSON files, see the detailed descriptions, which can be accessed via the links on the left.

Subtitles within Description

Component-mapping

the value of this property can be taken to map a AND library component

This must then be set up in the Mapping UI.

Value-mapping

Allowing you to use your own enums the value of this property can be translated to a AND value

Target

Information how the imported value will be stored within AND data

Recommended minimal content

• files must follow the GeoJSON standard
• sites must have geometry type “Point”
• trenches and ducts must have geometry type “LineString”

Apart from that, there are no really mandatory data in input. However, to get better results, it is recommended that you set the following properties in input:

1. duct.properties.type If that property isn’t set the duct will be imported as a trenchduct inside a trenchline. Microducts are only imported correctly, if the type of the legs is “sub_duct” and the type of the parents is “duct_package”.

2. duct.properties.parent_id If microduct legs have “parent_id” not set, the owning ductpackage is found by position. If several Microduct packages lie over each other the parent found by position is arbitrary. In that case “parent_id” must be set to ensure that the legs are connected to the right microduct package.

3. site.properties.logical_type Creating a routable network requires “logical_type” to be set for sites. If the “logical_type” is not set in the input, it is recommended to switch off “Create Pins” in the dialog for GisImport.

Coordinate System

Must be WGS84

optional you may use the non standard crs property for other coordinate systems/projections

Units

All lengths units are in meters
