The Geomap panel visualization allows you to view and customize the world map using geospatial data. You can configure various overlay styles and map view settings to easily focus on the important location-based characteristics of the data.
[[File:Visualize geomap 1.png|center|frameless|600x600px]]

== Map View ==
The map view controls the initial view of the map when the dashboard loads.

=== InitialView ===
The initialview configures how the GeoMap panel renders when the panel is first loaded.

* '''View''' sets the center for the map when the panel first loads.
* '''Fit to data''' fits the map view based on the data extents of Map layers and updates when data changes.
* '''Data''' option allows selection of extent based on data from “All layers”, a single “Layer”, or the“Last value” from a selected layer.
* '''Layer''' can be selected if fitting data from a single “Layer” or the “Last value” of a layer.
* '''Padding''' sets padding in relative percent beyond data extent (not available when looking at “Last value”only).
* '''MaxZoom''' sets the maximum zoom level when fitting data.
* '''Coordinates''' sets the map view based on:
** Latitude
** Longitude
* '''Zoom''' sets the initial zoom level.

Default Views are also available including:

* (0°,0°)
* NorthAmerica
* SouthAmerica
* Europe
* Africa
* WestAsia
* SouthAsia
* South-EastAsia
* EastAsia
* Australia
* Oceania

== Map layers ==
The Geomap visualization supports showing multiple layers. Each layer determines how you visualize geospatial data on top of the base map.

=== Types ===
There are three map layer types to choose from in the Geomap visualization.

* '''Markers''' renders a marker at each data point.
* '''Heatmap''' visualizes a heatmap of the data.
* '''GeoJSON''' renders static data from a GeoJSON file.

There are also five alpha layer types.

* '''Night / Day''' (alpha) renders a night / day region.
* '''Icon''' at last point (alpha) renders an icon at the last data point.
* '''Dynamic GeoJSON''' (alpha) styles a GeoJSON file based on query results.
* '''Route''' (alpha) render data points as a route.
* '''Photos''' layer (Alpha) renders a photo at each data point.

'''Note''': Basemap layer types can also be added as layers. You can specify an opacity.

=== Layer Controls ===
The layer controls allow you to create layers, change their name, reorder and delete layers.

* '''Add layer''' creates an additional, configurable data layer for the Geomap visualization. When you add a layer, you are prompted to select a layer type. You can change the layer type at any point during panel configuration. See the '''Layer Types''' section above for details on each layer type.

The layer controls allow you to rename, delete, and reorder the layers of the panel.

* '''Edit layer name''' (pencil icon) renames the layer.
* '''Trash Bin''' deletes the layer.
* '''Reorder''' (six dots/grab handle) allows you to change the layer order. Data on higher layers will appear above data on lower layers. The panel will update the layer order as you drag and drop to help simplify choosing a layer order.

You can add multiple layers of data to a single Geomap panel in order to create rich, detailed visualizations.

=== Location ===
The Geomap panel needs a source of geographical data. This data comes from a database query, and there are four mapping options for your data.

* '''Auto''' automatically searches for location data. Use this option when your query is based on one of the following names for data fields.
* '''Coords''' specifies that your query holds coordinate data. You will get prompted to select numeric data fields for latitude and longitude from your database query.
* '''Geohash''' specifies that your query holds geohash data. You will be prompted to select a string data field for the geohash from your database query.
* '''Lookup''' specifies that your query holds location name data that needs to be mapped to a value. You will be prompted to select the lookup field from your database query and a gazetteer. The gazetteer is the directory that is used to map your queried data to a geographical point.

== Basemap layer ==
A basemap layer provides the visual foundation for a mapping application. It typically contains data with global coverage. Several base layer options are available each with specific configuration options to style the base map.

=== Types ===
There are four basemaplayer types to choose from in the Geomap visualization.

* '''Open Street Map''' adds a map from a collaborative free geographic world database.
* '''CARTO''' adds a layer from CARTO Raster basemaps.
* '''ArcGIS''' adds a layer from an ESRI ArcGIS MapServer.
* '''XYZ''' adds a map from a generic tile layer.

=== Default ===
The default base layer uses the CARTO map. You can define custom default base layers in the .ini configuration file.
[[File:Visualize geomap 2.png|center|frameless|600x600px]]

==== Configure the default base layer with provisioning ====
You can configure the default base map using config files with FojiSoft’s provisioning system.

Use the JSONconfiguration option default_baselayer_config to define the default base map. There are currently four base map options to choose from: carto, esri-xyz, osm-standard, xyz. Here are some provisioning examples foreach base map option.

* '''carto''' loads the CartoDB tile server. You can choose from auto, dark, and light theme for the base map and can be set as shown below. The show Labels tag determines whether or not FojiSoft shows the Country details on top of the map. Here is an example:[[File:Visualize geomap 3.png|center|frameless|600x600px]]
* '''esri-xyz''' loads the ESRI tile server. There are already multiple server instances implemented to show the various map styles: world-imagery, world-physical, topo, usa-topo, and ocean. The custom server option allows you to configure your own ArcGIS map server. Here are some examples:[[File:Visualize geomap 4.png|center|frameless|600x600px]]

* '''osm-standard''' loads the OpenStreetMap tile server. There are no additional configurations needed and the config fields can be left blank. Here is an example:[[File:Visualize geomap 6.png|center|frameless|600x600px]]

* '''xyz''' loads a custom tile server defined by the user. Set a valid tile server url, with {z}/{x}/{y} for this option in order to properly load a default base map. Here is an example:[[File:Visualize geomap 7.png|center|frameless|600x600px]]

* '''enable_custom_baselayers''' allows you to enable or disable custom open source base maps that are already implemented. The default is true.

== Markers layer ==
The marker slayer allows you to display data points as different marker shapes such as circles, squares, triangles, stars, and more.
[[File:Visualize geomap markers 1.png|center|frameless|699x699px]]
[[File:Visualize geomap markers 2.png|center|frameless|590x590px]]

=== Marker Color ===
Configures the color of the marker. The default Single color keeps all points a single color. There is an alternate option to have multiple colors depending on the data point values and the threshold set at the Thresholds section.

=== Marker Size ===
Configures the size of the marker. The default is Fixed size, which makes all marker sizes the same regardless of the data points. However, there is also an option to scale the circles to the corresponding data points. Min and Max marker size has to be set such that the Marker layer can scale within this range.

=== Marker Shape ===
Allows you to choose the shape, icon, or graphic to aid in providing additional visual context to your data. Choose from assets that are included with FojiSoft such as simple shapes or the Unicon library. You can also specify a URL containing an image asset. The image must be a scalable vector graphic (SVG).

=== Fill opacity ===
Configures the transparency of each marker.

== Heatmap layer ==
The heatmaplayer clusters various data points to visualize locations with different densities. To add a heatmap layer:

Click on the drop-down menu under Data Layer and choose Heatmap.

Similar to Markers, you are prompted with various options to determine which data points to visualize and how you want to visualize them.
[[File:Visualize geomap heatmap 1.png|center|frameless|600x600px]]
[[File:Visualize geomap heatmap 2.png|center|frameless|528x528px]]

=== Weight values ===
Configure the intensity of the heatmap clusters.

* Fixed value keeps a constant weight value throughout all data points. This value should be in the range of 0~1.
* Similar to Markers, there is an alternate option in the drop-down to automatically scale the weight values depending on data values.

=== Radius ===
Configures the size of the heatmap clusters.

=== Blur ===
Configures the amount of blur on each cluster.

== GeoJSON layer ==
The GeoJSON layer allows you to select and load a static GeoJSON file from the filesystem.

* GeoJSON URL provides a choice of GeoJSON files that ship with FojiSoft.
* Default Style controls which styles to apply when no rules above match.

=== Color ===
Configures the color of the default style

=== Opacity ===
Configures the default opacity

=== Style Rules ===
Apply styles based on feature properties

Rule allows you to select a ''feature'', condition, and ''value'' from the GeoJSON file in order to define a rule. The trash bin icon can be used to delete the current rule.

==== Color ====
