Time Manager — Animation of temporal vector layers

Principle

You can create animations of your vectors, provided you have at least a layer with a column with a valid date/time.

Example

A video tutorial is available here: https://vimeo.com/83845949. It shows all the steps to use the functionality.

Prerequisites

The layer must be published as WFS (see WFS/OAPI) and the primary key must be published as well in the Layer properties.

Configuring the tool

After the configuration, your web application will display the symbol of a watch; clicking on it will open a small panel that will allow you to move between steps, or paly the entire animation. At startup, the application will load the entire table, so if you have thousands of objects you may need to wait for several seconds before the application is available.

Примечание

Several different formats for date/time are acceptable (those supported by the JavaScript library DateJS). You can check whether your format is supported by entering it in this page: https://github.com/datejs/Datejs

At the layer level

• For setting the time manager with one layer:

  1. Click the button.

  2. One layer with date/time capabilities.

  3. The start column with date/time. It can any kind of fields.

  4. The end column with date/time. This is optional.

  5. Date/time resolution of the chosen attribute(s).

  6. For not database based layer, you must compute the minimum and maximum values.

Предупреждение

Date/time resolution can have a different value than Frame type. You might select years for Frame type but your date field could have a Days resolution.

• To edit a layer in the table, select it and click the button or double click on the row.

• To remove a layer from the table, select it and click the button.

• To move a layer up or down, select it and click or buttons. The order will change in Lizmap too.

At the project level

Options:

• Time frame size

• Frame type

• Animation frame length
