Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
leaflet-splitmap
A Leaflet control to add a split screen to compare two map overlays.
This project is a fork of the leaflet-side-by-side plugin
L.control.splitMap(leftLayer[s], rightLayer[s])
Creates a new Leaflet Control for comparing two layers or collections of layers. It does not add the layers to the map - you need to do that manually. Extends L.Control but setPosition() and getPosition are noop because the position is always the same - it does not make sense for this control to be in the corner like other Leaflet controls.
Parameters
| parameter | type | description |
|---|---|---|
leftLayers |
L.Layer|array | A Leaflet Layer or array of layers to show on the left side of the map. Any layer added to the map that is in this array will be shown on the left |
rightLayers |
L.Layer|array | A Leaflet Layer or array of layers to show on the right side of the map. Any layer added to the map that is in this array will be shown on the right. These should not be the same as any layers in leftLayers |
options |
Object | Options |
options.padding |
Number | Padding between slider min/max and the edge of the screen in pixels. Defaults to 44 - the width of the slider thumb |
