Glossary

A​

Aggregation attribute​

An attribute whose values are used for calculations during data aggregation. The aggregation attribute can be the number of objects or a numeric attribute.

Example: when calculating the average number of building floors across different city districts, the aggregation attribute is the number of floors.

The term comparison attribute is also used for the Comparison widget and serves the same function.

Aggregation type​

A mathematical function applied during data aggregation: sum, average, median, minimum, maximum, percentiles.

Example: when aggregating data with the Average type for the Number of floors attribute, the average number of floors of buildings in the group is calculated.

Analytics scenarios​

Ready-made scenes with a set of layers based on built-in data with customized visualization and widgets.

For details, see the Analytics scenarios instruction.

D​

Dashboard​

A workspace for analytics consisting of one or more scenes with layers and widgets. Dashboards allow you to separate data workflows and manage access for different users.

Example: a dashboard "Competitor analysis" with two scenes: market overview and detail by district.

Data aggregation​

Converting multiple values into a single resulting value, which is displayed in widgets. The resulting value is calculated from values in a single group or range using a mathematical function (aggregation type).

Example: building floor values across city districts are aggregated into an average value for the city.

In 2GIS Pro, the term also refers to the functionality for creating a layer in which each area object is assigned a calculated value. For details, see the Data aggregation instruction.

Data sample​

A subset of data from a dataset with applied filters. If no filters are set, the sample includes all data from the dataset. Layers are created from data samples.

Example: the Purpose filter with the Residential value and the Number of floors filter with the >5 value are applied to the built-in Buildings dataset. Only residential buildings taller than five floors remain in the sample.

Data visualization​

The method of displaying layer data on the map: points, polygons, hexagons, etc.

For details, see the Data visualization section.

Dataset​

Source data in 2GIS Pro before filters are applied and layers are created.

Types of datasets:

  • Built-in - provided in the service by default or upon request.
  • Uploaded as a file - uploaded by the user as a one-time action.
  • Uploaded via API - uploaded by the user with the ability to add more data later.

For details, see the Data section.

E​

Export​

Downloading dashboards in .pdf format or custom datasets in .csv format from 2GIS Pro for use in other services or for storage.

For details, see the Exporting a dashboard and Operations with datasets instructions.

F​

Filter​

A condition for selecting data from a dataset. Filters are applied when creating a data sample and when filtering on a scene. By value type, filters can be text, numeric, logical, or geographic (geofilters).

Example: when applying the Material filter with the Brick value, only brick buildings remain in the sample.

Filtering data on a scene​

Additional filtering of a data sample when working with a scene: via geofilters, widgets, slices, or the Timeline widget.

During filtering, only the data display on the current scene changes. The original sample, layers, and widgets in other scenes remain unchanged.

For details, see the Filtering data on a scene instruction.

G​

Geofilters​

Filters that restrict data by a territory: district, radius from a point, custom polygon, etc. Applied when creating a data sample and when filtering on a scene.

For details, see the Geofilters section.

Global attribute​

An attribute that is used in different layers. Global attributes allow you to apply filtering via widgets and slices to multiple layers simultaneously.

Example: Demand and Firms datasets contain the Category global attribute.

Grouping​

Splitting data into groups by the values of a grouping attribute for display in widgets. For each group, an aggregated value is calculated using the selected aggregation type.

Example: grouping organizations by category to compare their counts.

Grouping attribute​

An attribute whose values are used to split data into groups during data aggregation. A text, logical, numeric attribute, or a Date type attribute can be used as a grouping attribute.

Example: when calculating average building floor counts across different city districts, the grouping attribute is the district.

L​

Layer​

A saved data sample with configured visualization on the map. Layers are created in dashboard scenes and are the primary unit of working with data.

Example: the "Residential buildings" layer is a sample of buildings visualized as polygons colored by floor count.

Legend​

A system widget displaying map symbols for data visualization elements on the map: colors, value ranges, and binding to layers. It is created automatically when a scene is created and updates when layer data changes.

For details, see the Legend instruction.

The term widget legend refers to a legend displayed within custom widgets.

Logical attribute​

An attribute that takes one of two values: true or false.

Examples: Open 24/7 (whether a store operates around the clock), Accessible environment (whether a building is accessible for people with reduced mobility).

M​

Map style​

A set of parameters defining the appearance of the base map: color scheme, label visibility, building and road display.

For details, see the Managing map style instruction.

Modifying a sample​

Changing the composition of a data sample in a layer by adding, removing, or editing filters. The original dataset is not affected.

For details, see the Modifying a sample instruction.

N​

Numeric attribute​

An attribute containing numeric values (integer or decimal).

Examples: Number of floors (building floor count), Number of branches (number of organization branches).

P​

Proximity zone​

An area on the map (isochrone) whose boundary can be reached within a specified time by a specified transportation type: on foot, by car, by public transport.

For details, see the Proximity zones instruction.

S​

Scene​

A page within a dashboard containing a set of layers and widgets. Scenes allow you to separate analytics scenarios within a single dashboard.

Example: one dashboard scene is used for population analysis, another is used for evaluating business locations.

Slice​

A filter on a scene that restricts data by attribute values. Configured via the system Slice Filter widget. Can be applied to a single layer or to multiple layers simultaneously through global attributes.

Only values from the original data sample are available in the Slice Filter widget.

For details, see the Filtering via slices section.

T​

Text attribute​

An attribute containing arbitrary text values.

Examples: Service language (the language spoken by staff), Deal type (rent or sale).

Tooltip​

A popup that appears when hovering over a data visualization element on the map. It contains the list of attributes selected during configuration of layer visualization and their values.

For details, see the Configuring a tooltip section.

Example: when you hover over an organization, the tooltip shows its name, number of branches, and number of reviews.

W​

Widget​

A visual element of a scene for presenting layer data as a chart, diagram, table, etc.

Widget types:

  • Custom - created by the user: line graph, column chart, etc.
  • System - available by default: legend, timeline, etc.

For the full list, see the Widget overview instruction.
