If outSR is not specified, the geometry is returned in the spatial reference of the map. The query will show all the features from the layer you selected which meet the criteria you build in the Query Builder. The orderBy statistic parameter can also be used to calculate the percentile. In some cases when using the resultOffset and resultRecordCount parameters, the exceededTransferLimit property may be included in the query results even though the value specified in the resultRecordCount has not been exceeded. Index intersect —The envelope of the query layer intersects the index entry for the target layer. Ask Question Asked 6 months ago. { In this tutorial, you learned a technique for querying and selecting features from an ArcGIS feature service. Description: This option can be used to specify the maxAllowableOffset to be used for generalizing geometries returned by the query operation. When StandardizedQueries is enabled, only expressions that conform to the specifications are allowed. I'm wondering if it's possible to create a script that loops through an ArcGIS Server REST API query in order to retrieve all features contained within the layer? For example, spatiotemporal based feature services support the like operator but do not support the not like operator or field equivalency expressions like field1 = field2. The result of this operation is either a feature set for each layer in the query or a count of features for each layer (if returnCountOnly is set to true) or an array of feature IDs for each layer in the query (if returnIdsOnly is set to true). The default is false. Related Information. If true, returns true curves in output geometries; otherwise, curves get converted to densified polylines or polygons. The historic moment to query. A feature layer is a table or view with at least one spatial column. This option supersedes the returnIdsOnly parameter. The default spatial relationship is intersects (esriSpatialRelIntersects). "definitionExpression": "LotSize > 5000" } "id": , // optional types Optional: any This parameter is shorthand for a WHERE clause of where like '%%'. All rights reserved. At 10.3.1, this option is available for hosted and nonhosted feature services. esriTimeUnitsUnknown>" A null value specified for start time or end time will represent infinity for start or end time, respectively. esriTimeUnitsHours | esriTimeUnitsMilliseconds | esriTimeUnitsMinutes | If the layer's source spatial reference has the desired precision and it is suitable for the client's use, the client can use the source layer's spatial reference as the output spatial reference. A feature layer is a table or view with at least one spatial column. 02-17-2016 11:48 AM. Syntax: An array of statistic definitions. The supported spatial relationships include intersects, contains, envelope intersects, within, and so on. Feature layer from an ArcGIS Server REST service. The result of this operation is one or more featuresets grouped by source layer / table object IDs. addition to the JSON structures, for envelopes and points, you can Query using the text parameter on a dynamic layer based on an existing layer: When returnIdsOnly=false and returnCountOnly=false, When groupByFieldsForStatistics and outStatistics are specified, Copyright © 2020 Esri. If you want to create an application that can access feature layer data you can use the ArcGIS REST API and the query operation. New at 10.6. Example: time=1199145600000 (1 Jan 2008 00:00:00 GMT), Example: time=1199145600000, 1230768000000 (1 Jan 2008 00:00:00 GMT to 1 Jan 2009 00:00:00 GMT), A null value specified for start time or end time will represent infinity for start or end time, respectively. "type": "table", The default is false. If true, m-values will be included in the results if the features have m-values. This sample shows how to page through records in a table. This operation is supported at 10.1 and later. Values: esriSpatialRelIntersects | esriSpatialRelContains | esriSpatialRelCrosses | esriSpatialRelEnvelopeIntersects | esriSpatialRelIndexIntersects | esriSpatialRelOverlaps | esriSpatialRelTouches | esriSpatialRelWithin. A valid field name can only contain alphanumeric characters and an underscore. "timeDataCumulative": , This option can be used to specify the number of records to skip in the response returned by the query operation. If multipatchOption = stripMaterials, the multipatch geometry will be returned without materials (i.e. At version 10.1, specifying geometry, objectIds, or gdbVersion parameters would return an error. For tables, it provides basic information about the table such as its ID, name, fields, types, and templates. query. A quick tour of working with Query Layers. The result of this operation is a feature set. By default, feature layers in ArcGIS Server 9.3.1 return 500 features. If there is no output spatial reference, the input geometry spatial reference is used. When an output spatial reference is not provided for a query operation, the Map Service derives coordinate quantization parameters from the layer's spatial reference. | LIKE ), (IN | NOT_IN) ( '(' ( expr ( ',' expr )* )? ')' "scaleSymbols": , The records can contain attribute and/or geometry information. In CodePen, click Fork and save the pen as ArcGIS JavaScript Tutorials: Query a feature layer. Suppose you want to … ArcGIS REST Query. For hosted services in ArcGIS Online or ArcGIS Enterprise, you can use Append operations available from the feature layer item page or ArcGIS REST API. Values: esriGeometryPoint | esriGeometryMultipoint | esriGeometryPolyline | esriGeometryPolygon | esriGeometryEnvelope. For layers, if you request geometry information, the To improve performance with field calculations, use the Calculate Field geoprocessing tool to calculate using an SQL expression when possible. The FeatureLayerView provides access to a layer's features that are displayed in the view.This sample uses the whenLayerView() method to get the FeatureLayer's layer view once it's created.. view.whenLayerView(featureLayer).then(function (lyrView) { // do something with the lyrView}); Once the layer view is available, you need to set up a watch on the updating property of the layer view. Description: If true, the response only includes an array of object IDs for each layer. This option was added at 10.3. You may also be able to edit the data represented by the feature layer. If outSR is not specified, the geometry is returned in the spatial reference of the map. Some sample … Description. As a service editor, ArcGIS Pro supports a wide range of geodatabase datasets and capabilities from supported databases. "showLabels": , Scene Viewer. This option was added at 10.3. Otherwise, Z values are not returned. You can also use a JSON representation for Layer Definitions. Layers that support percentiles include the advancedQueryCapabilities object property … You also learned how to filter a feature table to show a map that contains only the results that match a specific query string. To request geometry, set returnGeometry to true. Each feature service maintains metadata about layer rendering, field aliases, types, templates, and capabilities. types Optional: any In this case, the property will be true only if the the map. Description. This is most useful in large or complicated data sets. Values: esriSRUnit_Meter | esriSRUnit_StatuteMile | esriSRUnit_Foot | esriSRUnit_Kilometer | esriSRUnit_NauticalMile | esriSRUnit_USNauticalMile. A feature service allows clients to query and edit feature geometry and attributes. The default is true. Web feature layers (also known as feature services) are layers that are shared to support displaying, querying, and editing data on the web. Otherwise, the response is a feature set. At 10.3, this option is only available for hosted feature services. In the MapViewModel.cs, the class initializer method will simply call a single method, InitializeMap().
