Geometry coordinates are optimized for viewing and displaying of data. Applicable only to Image Service layers. Each projected and geographic coordinate system is defined by either a well-known ID (WKID) or a definition string (WKT). Used only in statistical queries. Note that all parameters related to geometry will be ignored when querying tables. Filters features from the layer based on pre-authored parameterized filters. If true, each feature in the returned FeatureSet will be returned with a centroid. Ask Question Asked 7 years, 8 months ago. Server-side and client-side layers. ArcGIS API for Python is a simple and lightweight library for analyzing spatial data, managing your Web GIS, and performing spatial data science. Only supported with ArcGIS Online hosted services or ArcGIS Enterprise 10.6 services. The query geometry is returned only for client-side queries and hosted feature services and if the layer's capabilities.query.supportsQueryGeometry is true. One or more field names used to order the query results. The smaller the scale, the lower the resolution of the geometries. With the ArcGIS Query Task you can perform attribute and spatial queries against data layers in a map service. ArcGIS for Desktop. This property is supported on all LayerView queries. An array of ObjectIDs to be used to query for features in a layer. This setting is provided in the layer resource. To display features included in the cluster as a collection of graphics. Possible Values:"upper-left"|"lower-left". The maximum distance in units of outSpatialReference used for generalizing geometries returned by the query operation. The units property indicates the unit of measurement. A JSON representation of the instance in the ArcGIS format. It uses point features representing oil and gas wells in relation to earthquake data. Spatial Queries on a Feature Layer. Apps and data for your organization ArcGIS Solutions. 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. A JSON representation of the instance in the ArcGIS format. Otherwise, the extent will be in the layer's spatial reference. Subscribe to RSS Feed; Mark Topic as New; Mark Topic as Read; Float this Topic for Current User; Bookmark ; Subscribe; Mute; Printer Friendly Page; spatial filter for relationship query? The geometry to apply to the spatial filter. Query is used to define parameters to filter a layer's features, either by its attributes or its geometry. This means that a feature might be returned from the query, even though its footprint is not in a spatial relationship with the geometry. However, the list of outFields does not need to include these two fields. A new instance of a Query object equal to the object used to call. If true, each feature in the returned FeatureSet includes the geometry. The declared class name is formatted as esri.folder.className. If tolerance is not specified, the maxAllowableOffset is used. The geometry to apply to the spatial filter. The well-known text that defines a spatial reference. ArcGIS for Developers. Used to project the geometry onto a virtual grid, likely representing pixels on the screen. by SteveMacLean. The disjoint spatial relationship returns features in the layer view that do not intersect the query geometry in anyway. Then I moved the data and maps to another installation of ArcGIS Server Enterprise on Windows 2008 Server 64bit with ArcSDE/PostgreSQL on a separate Windows 2008 Server 64bit. Datum transformation used for projecting geometries in the query results when outSpatialReference is different than the layer's spatial reference. // Query at a distance in pixels of the query geometry. Points are contained in polygons. This is only valid when outStatistics has been defined. Only supported with ArcGIS Online hosted services or ArcGIS Enterprise 10.6.1 services. Any legal SQL where clause operating on the fields in the layer is allowed. Indicates if the spatial reference of the map supports wrapping around the International Date Line. If neither num nor start properties are provided, then the default value of num is equal to the maxRecordCount of the service, which can be found at the REST endpoint of the FeatureLayer. 2. votes.
