arcgis.features module¶
The arcgis.features module contains types and functions for working with features and feature layers in the GIS.
Entities located in space with a geometrical representation (such as points, lines or polygons) and a set of properties can be represented as features. The arcgis.features module is used for working with feature data, feature layers and collections of feature layers in the GIS. It also contains the spatial analysis functions which operate against feature data.
In the GIS, entities located in space with a set of properties can be represented as features. Features are stored as feature classes, which represent a set of features located using a single spatial type (point, line, polygon) and a common set of properties. This is the geographic extension of the classic tabular or relational representation for entities - a set of entities is modelled as rows in a table. Tables represent entity classes with uniform properties. In addition to working with entities with location as features, the system can also work with non-spatial entities as rows in tables. The system can also model relationships between entities using properties which act as primary and foreign keys. A collection of feature classes and tables, with the associated relationships among the entities, is a feature layer collection. FeatureLayerCollections are one of the dataset types contained in a Datastore. Finally, features are not simply entities in a dataset. Features have a visual representation and user experience - on a map, in a 3D scene, as entities with a property sheet or popups.

FeatureLayer
(url, gis=None, container=None, dynamic_layer=None)¶ The feature layer is the primary concept for working with features in a GIS.
Users create, import, export, analyze, edit, and visualize features, i.e. entities in space as feature layers.
Feature layers can be added to and visualized using maps. They act as inputs to and outputs from feature analysis tools.
Feature layers are created by publishing feature data to a GIS, and are exposed as a broader resource (Item) in the GIS. Feature layer objects can be obtained through the layers attribute on feature layer Items in the GIS.

If out_sr is not specified, max_allowable_offset is assumed to be in the unit of the spatial reference of the layer.
out_sr
Optional Integer. The WKID for the spatial reference of the returned geometry.
geometry_precision
Optional Integer. This option can be used to specify the number of decimal places in the response geometries returned by the query operation. This applies to X and Y values only (not m or z-values).
gdb_version
Optional string. The geodatabase version to query. This parameter applies only if the isDataVersioned property of the layer is true. If this is not specified, the query will apply to the published map’s version.
return_geometry
Optional boolean. If true, geometry is returned with the query. Default is true.

result_record_count
Optional integer. This option can be used for fetching query results up to the result_record_count specified. When result_offset is specified but this parameter is not, the map service defaults it to max_record_count. The maximum value for this parameter is the value of the layer’s max_record_count property. This option is ignored if return_all_records is True (i.e. by default).

Optional string. The sql_format parameter can be either standard SQL92 standard or it can use the native SQL of the underlying datastore native. The default is none which means the sql_format depends on useStandardizedQuery parameter. Values: none | standard | native
return_true_curves
Optional boolean. When set to true, returns true curves in output geometries. When set to false, curves are converted to densified polylines or polygons.
return_exceeded_limit_features
Optional boolean. Optional parameter which is true by default. When set to true, features are returned even when the results include ‘exceededTransferLimit’: True.
When set to false and querying with resultType = tile features are not returned when the results include ‘exceededTransferLimit’: True. This allows a client to find the resolution in which the transfer limit is no longer exceeded without making multiple calls.
kwargs

geometry_precision
Optional integer. This option can be used to specify the number of decimal places in the response geometries.
out_wkid
Optional Integer. The spatial reference of the returned geometry.
gdb_version

validate_sql
(sql, sql_type='where')¶ The validate_sql operation validates an SQL-92 expression or WHERE clause. The validate_sql operation ensures that an SQL-92 expression, such as one written by a user through a user interface, is correct before performing another operation that uses the expression. For example, validateSQL can be used to validate information that is subsequently passed in as part of the where parameter of the calculate operation. validate_sql also prevents SQL injection. In addition, all table and field names used in the SQL expression or WHERE clause are validated to ensure they are valid tables and fields.
Argument
Description
sql
Required String. The SQL expression of WHERE clause to validate. Example: “Population > 300000”
sql_type
- Optional String. Three SQL types are supported in validate_sql
where (default) - Represents the custom WHERE clause the user can compose when querying a layer or using calculate.
expression - Represents an SQL-92 expression. Currently, expression is used as a default value expression when adding a new field or using the calculate API.
statement - Represents the full SQL-92 statement that can be passed directly to the database. No current ArcGIS REST API resource or operation supports using the full SQL-92 SELECT statement directly. It has been added to the validateSQL for completeness. Values: where | expression | statement
- Returns
dict
-
Table¶
-
class
arcgis.features.
Table
(url, gis=None, container=None, dynamic_layer=None)¶ Tables represent entity classes with uniform properties. In addition to working with “entities with location” as features, the GIS can also work with non-spatial entities as rows in tables.
Working with tables is similar to working with feature layers, except that the rows (Features) in a table do not have a geometry, and tables ignore any geometry related operation.

Optional Integer. This option can be used to specify the number of decimal places in the response geometries returned by the query operation. This applies to X and Y values only (not m or z-values).
gdb_version
Optional string. The geodatabase version to query. This parameter applies only if the isDataVersioned property of the layer is true. If this is not specified, the query will apply to the published map’s version.
return_geometry
Optional boolean. If true, geometry is returned with the query. Default is true.

return_true_curves
Optional boolean. When set to true, returns true curves in output geometries. When set to false, curves are converted to densified polylines or polygons.
return_exceeded_limit_features
Optional boolean. Optional parameter which is true by default. When set to true, features are returned even when the results include ‘exceededTransferLimit’: True.
When set to false and querying with resultType = tile features are not returned when the results include ‘exceededTransferLimit’: True. This allows a client to find the resolution in which the transfer limit is no longer exceeded without making multiple calls.
kwargs

The validate_sql operation ensures that an SQL-92 expression, such as one written by a user through a user interface, is correct before performing another operation that uses the expression. For example, validateSQL can be used to validate information that is subsequently passed in as part of the where parameter of the calculate operation. validate_sql also prevents SQL injection. In addition, all table and field names used in the SQL expression or WHERE clause are validated to ensure they are valid tables and fields.
Argument
Description
sql

sql_type
- Optional String. Three SQL types are supported in validate_sql
where (default) - Represents the custom WHERE clause the user can compose when querying a layer or using calculate.
expression - Represents an SQL-92 expression. Currently, expression is used as a default value expression when adding a new field or using the calculate API.
statement - Represents the full SQL-92 statement that can be passed directly to the database. No current ArcGIS REST API resource or operation supports using the full SQL-92 SELECT statement directly. It has been added to the validateSQL for completeness. Values: where | expression | statement
- Returns

FeatureLayerCollection¶
-
class
arcgis.features.
FeatureLayerCollection
(url, gis=None)¶ A FeatureLayerCollection is a collection of feature layers and tables, with the associated relationships among the entities.
In a web GIS, a feature layer collection is exposed as a feature service with multiple feature layers.
Instances of FeatureDatasets can be obtained from feature service Items in the GIS using FeatureLayerCollection.fromitem(item), from feature service endpoints using the constructor, or by accessing the dataset attribute of feature layer objects.
FeatureDatasets can be configured and managed using their manager helper object.
If the dataset supports the sync operation, the replicas helper object allows management and synchronization of replicas for disconnected editing of the feature layer collection.
Note: You can use the layers and tables property to get to the individual layers and tables in this feature layer collection.
