In other words, the geometries share some interior area, but not all interior area. An image coordinate system defines the spatial reference used to display the image in its original coordinates without distortion, map transformations or ortho-rectification. Query is used to define parameters to filter a layer's features, either by its attributes or its geometry. In this version of the API, you can implement your own draw tools using view events. If true, and returnGeometry is true, then z-values are included in the geometry. The geometry to apply to the spatial filter. The well-known ID of a spatial reference. See the example snippets below for an example of this. An image coordinate system defines the spatial reference used to display the image in its original coordinates without distortion, map transformations or ortho-rectification. Active 7 years, 8 months ago. Each coordinate is then snapped to one pixel on the grid. If outSpatialReference is not defined, the spatialReference of the data is used. When specifying the output fields, you should limit the fields to only those you expect to use in the query or the results. Each projected and geographic coordinate system is defined by either a well-known ID or a definition string .Note that for versions prior to ArcGIS 10, only WKID was supported. When value is not specified for any parameter in a request, the default value, that is assigned during authoring time, gets used. The contains spatial relationship returns features in the layer view that are completely contained by the query geometry. The Relational functions for ST_Geometry topic has additional details on how to construct these strings. The spatial relationship is determined by whether the boundaries or interiors of a geometry intersect. has the same properties as featureLayerView.filter = new FeatureFilter({ geometry: myGeometry // Spatial timeExtent: myTimeExtent, // Temporal where: myWhere // Aspatial }); FeatureFilter Query This indicates the Projected Coordinate System or the Geographic Coordinate System used to locate geographic features in the map. L.esri.Query is an abstraction for the query API included in Feature Layers and Image Services. I can re-run the javascript against the new installation and all of the spatial queries return an error: The ArcGIS JavaScript API 3.16 was released this past Friday and it has many new features to showcase on the big screen. The query geometry is returned only for client-side queries and hosted feature services and if the layer's capabilities.query.supportsQueryGeometry is true. Defines the spatial reference of a view, layer, or task parameters. Ask Question Asked 7 years, 8 months ago. Converts an instance of this class to its ArcGIS portal JSON representation. See the, // Will execute query for features represented by the clusterGraphic, // query the above stats for each region in the layer, "AVG(CUSTOMERS) >= 1,000 AND MIN(RATING) >= 3", // query the above stats for all regions where, // the average number of daily customers per business is, // greater than 1,000 and the minimum customer rating, // query for data returned from an expressions and other fields as the following field names, // where POP_CHANGE_2020 represents the population change from 2010 - 2020, "( (POP2020 - POP2010) / POP2010 ) * 100 as POP_CHANGE_2020". The Dimensionally Extended 9 Intersection Model (DE-9IM) matrix relation (encoded as a string) to query the spatial relationship of the input geometry to the layer's features. Define them either in FeatureLayer.outFields or SceneLayer.outFields. This limitation does not apply to FeatureLayer, CSVLayer, and CSVLayerView queries. The units of tolerance will match the units of outSpatialReference. To push clustered features to the view's popup for browsing. The within spatial relationship returns features in the layer view that completely contain the query geometry. If true, then all features are returned for each tile request, even if they exceed the maximum record limit per query indicated on the service by maxRecordCount. You can also combine these query types to perform a … to retrieve "pages" of results when querying). An array of Object IDs representing aggregate (i.e. Query is used to define parameters to filter a layer's features, either by its attributes or its geometry. This feature set contains feature objects including the values for the fields requested by the user. See the, // get image coordinate system of the specified catalog item, // create a spatialReference object and set its, // autocasts to esri/geometry/SpatialReference, // Calculate an extent for the mapview based on the image's extent, // set the MapView's spatialReference to the image's coordinate system, // and the extent to the extent calculated above, // returns true if the webMercatorUtils can, // project geometries from WGS84 to Web Mercator. You can also combine these query types to perform combined attribute and spatial queries. It limits how far any part of the generalized geometry can be from the original geometry.
