Maps & Geospatial Tools

1. Fuzzy Search & Attribute Filtering

The Fuzzy Search tool allows users to search for specific features within the layers they have access to.

  1. Click the Fuzzy Search tool.
  2. Select the layer you want to search (e.g., Country).
  3. Enter or select a search keyword, such as a country name.

Mini Toolbar Controls

Each layer in the Layer List includes a mini toolbar:

Control Name Description
1 Hide Layer Toggles layer visibility on/off
2 Zoom to all Centers map view to layer full extent
3 GeoServer style Applies or modifies GeoServer SLD styles
4 Legend Displays symbology legend for the layer
5 Opacity Adjusts layer transparency slider
6 Delete Removes layer from the workspace
