dojo.require("esri.tasks.geoenrichment.GeographyLevel");
Description
(Added at v3.6)
GeographicLevel
works with
IntersectingGeographies
to define a study area of
InfoGraphic
with a feature from a standard geography layer. You may use this class to define your study area as a standard census unit (such as a state, county, tract, etc). To be used in favor of the
levels
property in the
IntersectingGeographies class.
Only limited layers are available to construct a
GeographicLevel
object. Refer to the
GeoEnrichment Coverage section of the ArcGIS GeoEnrichment Service documentation to find the countries where data are available. The
"ID" column in the
Standard Geography Levels table lists all the layer IDs you may use.

Sample: var infographics = new esri.dijit.geoenrichment.Infographic({
type: "AgePyramid",
variables: ["Age.*"],
studyAreaOptions: new esri.tasks.geoenrichment.IntersectingGeographies({
levels: [
new esri.tasks.geoenrichment.GeographyLevel({

}, "infographics");
Property Details
The ID of the country for which data is retrieved. Optional when constructing a
GeographyLevel
. If not specified, the server will automatically determine the country. Specifying the country ID can eliminate computational cost and potentially improve the performance of your application.
Refer to the
GeoEnrichment Coverage section of the ArcGIS GeoEnrichment Service documentation to find the countries where data are available. The
"Two-Digit Country Code" column in the first table lists all the country codes you may use.
The ID of the dataset to which variables used in this
GeographyLevel
belong. Optional when constructing a
GeographyLevel
. If not specified, the server will automatically determine the dataset. Specifying the dataset ID can eliminate computational cost and potentially improve the performance of your application.
Refer to the
GeoEnrichment Coverage section of the ArcGIS GeoEnrichment Service documentation to find available dataset. Request latest available datasets at
