Create radius for objetcs on mapview*

5 min Advanced


What is radius in vMAP?

Radius is generating an area for selected objects (points or polygons) on the mapview based on different conditions, such as radius distance, driving distance, driving time. This feature can be used to generate area for marketing, sales and delivery activities, or other activities involving locations and areas.

For example, if you are opening a new pizza restaurant and you want to know how far your deliverers can reach from your store in 30 minutes, you can generate a delivery area on the mapview with Route in minutes distance type to check and find the possible location of your customer.

How do I create radius for objects?

Step 1. Load object(s) for area planning

Note: Before you select point from the mapview, please make sure you have added points or polygons on the mapview or imported point/polygon data file onto the mapview.)

First, click the radius1 icon on the toolbar at the bottom of vMAP main page. In the Create radius window, you can select and load objects.

vMAP offers two approaches to load objects.

Approach 1: Search for objects and load

In the Create radius window, to open the Object Search window, click radius3 button.

In the Object search window, filter and search for objects with at most three conditions. All the objects meet the searching conditions will be displayed in the bottom grid.

Select objects that meet your requirements by checking the checkbox of objects and click the Apply buttonw.

Approach 2: Directly select objetcs on mapview and load

To select objects on the mapview directly, click one or several objects, then click the radius12 icon on the Create radius window.

Note: You can select only one object (point or polygon) for radius area calculating, or select multiple objects at the same time, then multiple araes will be calculated accordingly. Here we take one point object as example.

Step 2. Define Distance type

After loading the object, check its checkbox. Then choose one of the following Distance types:

  • Radius in Meter: Create a circle area based on given straight-line distance
  • Route in Meter: Create an area based on the route distance
  • Route in Minutes: Create an area based on the given route time

If choosing Radius in Meter, you need to set Radius interval then.

While if choosing Route in Meter or Route in Minutes, before setting Radius interval, you need to select Transportation Type from car, bicycle, pedestrian or truck.

Then click add_icon to set Radius interval.

Step 3. Set radius interval

In the Radius interval window,

Subdivisions field means how many radius areas in different levels will be calculated based on the selected object. Here we choose 3 intervals.

Value means the interval range.

The other fields are for the radius color style settings.

Click generate_button button to save the interval settings. You can also insert or delete intervals, or change their covering color orders in Actions column of the interval grid.

Step 4. Select Target layer

Note: In order to save the radius data, 4 data fields must be created within the layer type: Area Color, Color Edge, Opacity and Border size.

System: If any layer of the current mapview contains the 4 required data fields, then vMAP will automatically match and save the data in it.

Customized: Select one layer, and choose its four fields to match and save the 4 data fields.

You can also create a new layer which will be automatically added with the 4 required data fields by clicking auto_create_layer_icon icon.

If the checkbox of Overwrite is checked, the radius on the target layer will be named after the selected object, then the object with the same name on the same layer will be overwritten and deleted.

Step 5. Generate radius

Click generate_button button to save the settings. After the generating process completes, you can view the radius result on the newly created layer on the mapview.
