JavaScript Methods
Map Interaction
Geographic Maps can be panned, zoomed, and modified.
| Method | Description |
| F1.Maker.Map | Create a new map on the page |
| setExtent | Set the map geographic boundaries. |
| getCenterZoom | Get map geographic center location coordinates and zoom level. |

| setZoom | Set a new map zoom level. |
| getMapProviderList | |
| getBasemap | Get the current basemap layer and projection. |
| setBasemap | Change the basemap to a new tile layer. |
| saveMap | Save the current map state to GeoIQ. |
| setStyle | Change the map styling such as Zoom and Legend. |
Map Layers
Layers are styled datasets on a map. They can be simple styles such as color, size, or transparency. For more advanced visualizations thematic styling can vary the styling by an attribute value or category.
| Method | Description |
| getLayers | Returns a list of the map layers. |
| removeLayer | Remove a specific layer from the map. |
| addLayer | Add a data layer and styling to the map. |
| showLayer | Change the visibility of a layer. |
| getLayer | Get the layer styling and metadata. |
| setLayerStyle | Change the layer styling. |
| setLayerTitle | Set the layer title for the legend. |
| setLayerSubTitle | Set the layer subtitle for the legend. |
| addLayerCategoryFilter | Style the layer icons that match a list of categories and URLs. |
| addLayerInfoWindowFilter | Style the infowindow contents for a layer. |
Layer Filters
Map layers can be filtered to show a limited subset of data based on an attribute, or visible area. It is also possible to highlight specific dataset features based on a simple or complex comparison with the attributes.
| Method | Description |
| addFilter | Add a new limit expression to a layer. |
| removeFilter | Remove a limit expression by name from a layer. |
| getFilters | Get the array of current limit expressions for a layer. |
| clearFilters | Remove all limit expressions from the layer. |
| addHighlight | Highlight features of a layer by a filter expression. |
| removeHighlight | Remove a highlight expression from a layer. |
| clearHighlights | Remove all highlights from a layer. |
Data Features API
Each dataset layer has a collection of features, or individual geographic points, lines or polygons. It is possible to access all of the features or some features. Drawing new features must be added to an existing layer.
| Method | Description |
| addFeatures | Add an array of features to a layer. |
| getFeatures | Get the current list of features that are part of the layer. |
| getVisibleFeatures | Get only the currently visible features by limit expressions and geographic extents. |
Temporal Controls
Map layers can be animated by a time attribute.
| Method | Description |
| setLayerTemporalAttribute | Specify a temporal attribute for a layer to be animated with. |
| setTemporalResolution | Set the time resolution for an attribute. |
| getTemporalResolution | Get the current time resolution for a layer. |
| getTimeSlots | Get an array of the features in all time slots. |
| setTimeSpan | Set the currently visible time span. |
| getTimeSpan | Get the currently visible time span. |
| getGlobalTimeSpan | Get the extent of all time features in a layer. |
| setTimeFilter |
