r	tab

Returns

string

property df

Returns

Pandas’ DataFrame

property fields

Returns the fields values for the CSV source.

Returns

list of strings

property latitude

The latitude field name. If not specified, the class will look for following field names in the CSV source: “lat”, “latitude”, “y”, “ycenter”, “latitude83”, “latdecdeg”, “POINT-Y”.

property longitude

The longitude field name. If not specified, the CSVLayer will look for following field names in the CSV source: “lon”, “lng”, “long”, “longitude”, “x”, “xcenter”, “longitude83”, “longdecdeg”, “POINT-X”.

property opacity

Float

property properties

Returns the properties of the Layer.

Returns

PropertyMap

property renderer

Get/Set the Renderer of the CSV Layer

Returns

InsensitiveDict

property scale

Gets/Sets the Min/Max Scale for the layer

property sql_expression

The SQL where clause used to filter features on the client. Only the features that satisfy the definition expression are displayed in the widget. Setting a definition expression is useful when the dataset is large and you don’t want to bring all features to the client for analysis. The sql_expressions may be set when a layer is constructed prior to it loading in the view or after it has been loaded into the class.

Returns

String

property title

The title of the layer used to identify it in places such as the Legend and LayerList widgets.

Returns

String

GeoJSONLayer

class arcgis.mapping.ogc.GeoJSONLayer(url=None, data=None, **kwargs)

Bases: arcgis.mapping.ogc._base.BaseOGC

The GeoJSONLayer class is used to create a layer based on GeoJSON. GeoJSON is a format for encoding a variety of geographic data structures. The GeoJSON data must comply with the RFC 7946 specification which states that the coordinates are in spatial reference: WGS84 (wkid 4326).

Argument	Description
url	Optional string. The web location of the GeoJSON file.
data	Optional String or Dict. A path to a GeoJSON file, the GeoJSON data as a string, or the GeoJSON data as a dictionary.
copyright	Optional String. Describes limitations and usage of the data.
opacity	Optional Float. This value can range between 1 and 0, where 0 is 100 percent transparent and 1 is completely opaque.
renderer	Optional Dictionary. A custom set of symbology for the given geojson dataset.
scale	Optional Tuple. The min/max scale of the layer where the positions are: (min, max) as float values.
title	Optional String. The title of the layer used to identify it in places such as the Legend and Layer List widgets.

GeoRSSLayer

class arcgis.mapping.ogc.GeoRSSLayer(url, **kwargs)

Bases: arcgis.mapping.ogc._base.BaseOGC

The GeoRSSLayer class is used to create a layer based on GeoRSS. GeoRSS is a way to add geographic information to an RSS feed. The GeoRSSLayer supports both GeoRSS-Simple and GeoRSS GML encodings, and multiple geometry types.

It exports custom RSS tags as additional attribute fields in the form of simple strings or an array of JSON objects.

Argument	Description
url	Required string. The web address of the GeoRSS sevice.
copyright	Optional String. Describes limitations and usage of the data.
line_symbol	Optionl Dict. The symbol for the polyline data in the GeoRSS.
