Time Manager Workshop at #QGIS2015 Conference in Nodebo

35,336 views

Published on

This talk presents QGIS visualization tools with a focus on efficient use of layer styling to both explore and present spatial data. Examples include the recently added heatmap style as well as sophisticated rule-based and data-defined styles. Additionally, we will have a special look at exploring and presenting spatio-temporal data using the Time Manager plugin. As a special treat, we will look into creating time-dependent styles using expression-based styling to access the current Time Manager timestamp.

The second part is a workshop about hands-on experience with Time Manager. Time Manager makes it possible to explore spatio-temporal data by creating animations directly in QGIS. We’ll cover data requirements, configuration, as well as time-dependent styling and creating animations.Visual exploration and presentation of spatial data using QGIS
