Proximity zones

Proximity zone is an area the boundaries of which can be reached by the chosen method of transportation (for example, by car or on foot) within a certain period of time. You can build walking/transport proximity zones for several objects at once, as well as to calculate statistics within them (for example, the total number of residents within a 15-minute walking proximity zone).

Example scenario

Build a coverage area for clinics within a 20-minute walk to make a decision about opening an additional department of the clinic.

Functionality is not available in demo mode. For more information, see the Tariffs page.

Proximity zones button
  1. Create a layer with the objects you are interested in. The way of data visualization for the layer does not matter.

  2. Modify the filtering results so that no more than 500 objects remain as a result of filtering.

  3. Select the Proximity Zones tool in the layer settings.

  4. Build proximity zones:

    Building of walking or transport proximity zones
    • Source layer: select a layer, for objects of which proximity zones will be built.

    • New layer name: specify the name of the resulting layer.

    • Proximity type: select the proximity type: walking or driving.

    • Zones:

      • Configure the number of steps (from 1 to 5, default is 3). To increase this number, click Add Zone. To decrease, click the Delete icon next to the necessary step.
      • Configure the size of each step (from 1 to 30 minutes to the point or centroid of the polygon). By default, a new step is added with a gap of 5 minutes.
    • Merge zones of different points: enable this setting to make overlapping proximity zones merge into one. If this setting is disabled, intersections of proximity zones will be shown on the resulting layer.

  5. Click Create.

The number of proximity zones buildings is limited for each tariff. Limits for each parameter are displayed in the proximity zones dialog:

  • Points: the number of points for which proximity zones are built.
  • Zones: the number of proximity zones that will be built for these points.
  • Available: the number of remaining requests for building proximity zones according to your tariff. A request is building one proximity zone for a single point/centroid of a polygon. To increase the limit, contact the sales department.

You can configure proximity zones using the panel of the created layer:

  • To change parameters used for building zones and learn about current limits, click Set steps.
  • To aggregate data within proximity zones (for example, to display the number of objects in each zone), click Aggregate data. See detailed instruction for configuring aggregation.
Visualization settings
  • Step colors: the selection of color scale of data display. To change the default step colors, click on the color scale of the step and enter a new color value in HEX format.
  • Opacity: adjustment of the transparency of displaying elements on the map.
