Collapsible sub layers

[andredaa]

Introducing grouped layers. Layers can contain a group of sublayers that have similar contents to render, but listen to a different endpoint Layers can even contain subresults that are included in the information coming from the endpoint.

First Used Case

Walkability for different walking speeds (walking, walking with stroller, wheelchair)

• Sublayers: Walking, Stroller, Wheelchair -- Walkability results are obtained from 3 endpoints ("cityIo/.../walkability_adult", "cityIo/.../walkability_wheelchair", ...)
• Subresults: Schools, Groceries, Culture -- Each walkability result contains 3 subresults (walkability towards schools, groceries or cultural institutions)

If specified in the config.json, all sublayers and subresults will be displayed in the layer menu.

How to add sublayers or subresults

Sublayers

in order to add grouped sublayers to a layer, in config.json add "groupedLayersData": [ { "displayName": "Adult", "id": "walkability_adult", "url": "https://cityio.media.mit.edu/api/table/grasbrook_test/walkability_walking", "propertyToDisplay": "educational", "legendStyleField": "educational", "legendDescription": "A visualization of walking time (in minutes) needed to reach the closest school." }, {...}, ]

Subresults

To add subresults in config.json add to your layer : "subResults": [ { "id": "educational", "label": "Schools" }, { "id": "grocery", "label": "Groceries" }, { "id": "culture", "label": "Cultural Institutions" } ],
