Layers

In TreeKeeper, layers are available to view on top of the base map, showing different types of data in different ways. Certain layers can be viewable by guests while others can be hidden from their view. Contact TreeKeeper Support if you would like to make certain layers available/unavailable to guests.


Overlays

Overlays are the layers that render on top of the base map and can display different types of data in TreeKeeper.

Toggling Layers

Clicking on the “eye” icon for a layer will toggle its visibility:

LayerOn.png - Layer is on; displaying features on the map.
LayerOff.png - Layer is off; not displaying features on the map.

Viewing Layer Legends

To see the symbology of a layer, its legend can be viewed by clicking on the Layer Card or the arrow on the right side.

Reordering Layers

Users can change the order of their layers on the fly! To reorder layers:

  1. Click the “Locked” icon LockedLayers.png to unlock your layer list.

  2. With the drag indicator LayerDragIndicator.png, drag and drop layers where you would like.

  3. When finished, click the “Unlocked” icon UnlockedLayers.png to lock your layer list again.

The order is reflected on the map, so layers at the top will display on top of any active layers below it. Because of that, we suggest having Selected Layers on top of Data Layers on top of Reference Layers.

Setting Layers to Inactive

Users can deactivate layers, which moves them out of the Active Layers section and into the Inactive Layers section. This is helpful for larger systems that have different teams working on different data/features. To set layers to inactive:

  1. Click the “Locked” icon LockedLayers.png to unlock your layer list.

  2. Deactivate/Activate layer

    • Deactivate: In Active Layers, click the “Remove” icon RemoveLayer.png next to the layer you want to deactivate.

    • Activate: In Inactive Layers, click the “Add” icon ReactivateLayer.png next to the layer you want to activate.

  3. When finished, click the “Unlocked” icon UnlockedLayers.png to lock your layer list again.

Inactive Layers

Inactive Layers are separated into 3 different groups:

  • Selected.png are used to highlight sites that are available in the data grid. Sites can be selected from map tools or searches.

  • Layers.png are all the data-based layers in the system that you can add points/lines/polygons to.

  • Reference.png are commonly shapefiles storing information that doesn’t change often, like City Limits or Wards.

Base Layers

Located in the upper-right corner of the TreeKeeper map are the Base Layers which include Google Street, Google Satellite, and Open Street Map.

For Google Street (Map), you can enable or disable Terrain.

For Google Satellite (Satellite), you can enable Labels for Streets, Buildings, and other map objects.

Description

Data Layer (Layer, Facility)

A data layer is a set of data managed by the TreeKeeper system. Traditionally, these are broken down into Street Trees, Private Trees, or Park Trees, but can be any type of asset you’d like to manage and track. A typical TreeKeeper system will come with a Data Layer for its main inventory.

Selected Layer (Facility)

A selected layer is a form of data layer that renders search results or a map-selection set.

Visual (Data Subset) Layer

These are custom visual representations in the system. Where there may be only one facility or set of data, there could be multiple visual layers to represent different parts of the data or display the data in a different way.

Reference Layer

These are external files hosted on Davey’s mapping servers that display different layers such as city limits, park boundaries, bodies of water, streets, and parcels. Please consult with your GIS department (if applicable) to see what shapefiles they have available for integration into TreeKeeper.

External Reference Layer (WMS/WFS Layer)

These layers are unique as Davey is not the host of the data but rather consumes a hosted service in order to display that information in TreeKeeper. Please see WMS/WFS Layer for more information.

Base Layers

No map is complete without a base layer to reference data against. These options, found below your other layers, offer varying views of the surrounding area. By default, the Google Maps is enabled, but you can also choose from other options like Google Satellite and Open Street Maps.

Aerial Imagery

There is an option to configure a .SID aerial imagery file for use in TreeKeeper. Not to worry though! If you do not have aerial imagery, Google Satellite is available in base layers.
