[[tilemap]] === Tile Maps A tile map displays a geographic area overlaid with circles keyed to the data determined by the buckets you specify. The default _metrics_ aggregation for a tile map is the *Count* aggregation. You can select any of the following aggregations as the metrics aggregation: *Count*:: The {ref}search-aggregations-metrics-valuecount-aggregation.html[_count_] aggregation returns a raw count of the elements in the selected index pattern. *Average*:: This aggregation returns the {ref}search-aggregations-metrics-avg-aggregation.html[_average_] of a numeric field. Select a field from the drop-down. *Sum*:: The {ref}search-aggregations-metrics-sum-aggregation.html[_sum_] aggregation returns the total sum of a numeric field. Select a field from the drop-down. *Min*:: The {ref}search-aggregations-metrics-min-aggregation.html[_min_] aggregation returns the minimum value of a numeric field. Select a field from the drop-down. *Max*:: The {ref}search-aggregations-metrics-max-aggregation.html[_max_] aggregation returns the maximum value of a numeric field. Select a field from the drop-down. *Unique Count*:: The {ref}search-aggregations-metrics-cardinality-aggregation.html[_cardinality_] aggregation returns the number of unique values in a field. Select a field from the drop-down. The _buckets_ aggregations determine what information is being retrieved from your data set. Before you choose a buckets aggregation, specify if you are splitting the chart or displaying the buckets as *Geo Coordinates* on a single chart. A multiple chart split must run before any other aggregations. Tile maps use the *Geohash* aggregation as their initial aggregation. Select a field, typically coordinates, from the drop-down. The *Precision* slider determines the granularity of the results displayed on the map. See the documentation for the {ref}/search-aggregations-bucket-geohashgrid-aggregation.html#_cell_dimensions_at_the_equator[geohash grid] aggregation for details on the area specified by each precision level. Kibana supports a maximum geohash length of 7. NOTE: Higher precisions increase memory usage for the browser displaying Kibana as well as for the underlying Elasticsearch cluster. Once you've specified a buckets aggregation, you can define sub-aggregations to refine the visualization. Tile maps only support sub-aggregations as split charts. Click *+ Add Sub Aggregation*, then *Split Chart* to select a sub-aggregation from the list of types: *Date Histogram*:: A {ref}search-aggregations-bucket-datehistogram-aggregation.html[_date histogram_] is built from a numeric field and organized by date. You can specify a time frame for the intervals in seconds, minutes, hours, days, weeks, months, or years. You can also specify a custom interval frame by selecting *Custom* as the interval and specifying a number and a time unit in the text field. Custom interval time units are *s* for seconds, *m* for minutes, *h* for hours, *d* for days, *w* for weeks, and *y* for years. Different units support different levels of precision, down to one second. *Histogram*:: A standard {ref}search-aggregations-bucket-histogram-aggregation.html[_histogram_] is built from a numeric field. Specify an integer interval for this field. Select the *Show empty buckets* checkbox to include empty intervals in the histogram. *Range*:: With a {ref}search-aggregations-bucket-range-aggregation.html[_range_] aggregation, you can specify ranges of values for a numeric field. Click *Add Range* to add a set of range endpoints. Click the red *(x)* symbol to remove a range. After changing options, click the green *Apply changes* button to update your visualization, or the grey *Discard changes* button to keep your visualization in its current state. *Date Range*:: A {ref}search-aggregations-bucket-daterange-aggregation.html[_date range_] aggregation reports values that are within a range of dates that you specify. You can specify the ranges for the dates using {ref}common-options.html#date-math[_date math_] expressions. Click *Add Range* to add a set of range endpoints. Click the red *(/)* symbol to remove a range. *IPv4 Range*:: The {ref}search-aggregations-bucket-iprange-aggregation.html[_IPv4 range_] aggregation enables you to specify ranges of IPv4 addresses. Click *Add Range* to add a set of range endpoints. Click the red *(/)* symbol to remove a range. *Terms*:: A {ref}search-aggregations-bucket-terms-aggregation.html[_terms_] aggregation enables you to specify the top or bottom _n_ elements of a given field to display, ordered by count or a custom metric. *Filters*:: You can specify a set of {ref}search-aggregations-bucket-filters-aggregation.html[_filters_] for the data. You can specify a filter as a query string or in JSON format, just as in the Discover search bar. Click *Add Filter* to add another filter. Click the image:images/labelbutton.png[] *label* button to open the label field, where you can type in a name to display on the visualization. *Significant Terms*:: Displays the results of the experimental {ref}search-aggregations-bucket-significantterms-aggregation.html[_significant terms_] aggregation. The value of the *Size* parameter defines the number of entries this aggregation returns. *Geohash*:: The {ref}search-aggregations-bucket-geohashgrid-aggregation.html[_geohash_] aggregation displays points based on the geohash coordinates. NOTE: By default, the *Change precision on map zoom* box is checked. Uncheck the box to disable this behavior. You can click the *Advanced* link to display more customization options for your metrics or bucket aggregation: *Exclude Pattern*:: Specify a pattern in this field to exclude from the results. *Exclude Pattern Flags*:: A standard set of Java flags for the exclusion pattern. *Include Pattern*:: Specify a pattern in this field to include in the results. *Include Pattern Flags*:: A standard set of Java flags for the inclusion pattern. *JSON Input*:: A text field where you can add specific JSON-formatted properties to merge with the aggregation definition, as in the following example: [source,shell] { "script" : "doc['grade'].value * 1.2" } NOTE: In Elasticsearch releases 1.4.3 and later, this functionality requires you to enable {ref}modules-scripting.html[dynamic Groovy scripting]. The availability of these options varies depending on the aggregation you choose. Select the *Options* tab to change the following aspects of the chart: *Map type*:: Select one of the following options from the drop-down. *_Scaled Circle Markers_*:: Scale the size of the markers based on the metric aggregation's value. *_Shaded Circle Markers_*:: Displays the markers with different shades based on the metric aggregation's value. *_Shaded Geohash Grid_*:: Displays the rectangular cells of the geohash grid instead of circular markers, with different shades based on the metric aggregation's value. *_Heatmap_*:: A heat map applies blurring to the circle markers and applies shading based on the amount of overlap. Heatmaps have the following options: * *Radius*: Sets the size of the individual heatmap dots. * *Blur*: Sets the amount of blurring for the heatmap dots. * *Maximum zoom*: Tilemaps in Kibana support 18 zoom levels. This slider defines the maximum zoom level at which the heatmap dots appear at full intensity. * *Minimum opacity*: Sets the opacity cutoff for the dots. * *Show Tooltip*: Check this box to have a tooltip with the values for a given dot when the cursor is on that dot. *Desaturate map tiles*:: Desaturate the map's color in order to make the markers stand out more clearly. *WMS compliant map server*:: Check this box to enable the use of a third-party mapping service that complies with the Web Map Service (WMS) standard. Specify the following elements: * *WMS url*: The URL for the WMS map service. * *WMS layers*: A comma-separated list of the layers to use in this visualization. Each map server provides its own list of layers. * *WMS version*: The WMS version used by this map service. * *WMS format*: The image format used by this map service. The two most common formats are `image/png` and `image/jpeg`. * *WMS attribution*: An optional, user-defined string that identifies the map source. Maps display the attribution string in the lower right corner. * *WMS styles*: A comma-separated list of the styles to use in this visualization. Each map server provides its own styling options. After changing options, click the green *Apply changes* button to update your visualization, or the grey *Discard changes* button to keep your visualization in its current state. [float] [[navigating-map]] ==== Navigating the Map Once your tilemap visualization is ready, you can explore the map in several ways: * Click and hold anywhere on the map and move the cursor to move the map center. Hold Shift and drag a bounding box across the map to zoom in on the selection. * Click the *Zoom In/Out* image:images/viz-zoom.png[] buttons to change the zoom level manually. * Click the *Fit Data Bounds* image:images/viz-fit-bounds.png[] button to automatically crop the map boundaries to the geohash buckets that have at least one result. * Click the *Latitude/Longitude Filter* image:images/viz-lat-long-filter.png[] button, then drag a bounding box across the map, to create a filter for the box coordinates.
