<h1>Time Manager</h1>
<p>Time Manager filters your layers and displays only layers and features that match the specified time frame. Time Manager supports vector layers and raster layers (including WMS-T).</p>
<p>Timestamps have to be in one of the following formats:</p>
<ul>
<li class="mono">%Y-%m-%d %H:%M:%S.%f</li>
<li class="mono">%Y-%m-%d %H:%M:%S</li>
<li class="mono">%Y-%m-%d %H:%M</li>
<li class="mono">%Y-%m-%dT%H:%M:%S</li>
<li class="mono">%Y-%m-%dT%H:%M:%SZ</li>
<li class="mono">%Y-%m-%dT%H:%M</li>
<li class="mono">%Y-%m-%dT%H:%MZ</li>
<li class="mono">%Y-%m-%d</li>
<li class="mono">%Y/%m/%d %H:%M:%S.%f</li>
<li class="mono">%Y/%m/%d %H:%M:%S</li>
<li class="mono">%Y/%m/%d %H:%M</li>
<li class="mono">%Y/%m/%d</li>
<li class="mono">%H:%M:%S</li>
<li class="mono">%H:%M:%S.%f</li>
<li class="mono">%Y.%m.%d %H:%M:%S.%f</li>
<li class="mono">%Y.%m.%d %H:%M:%S</li>
<li class="mono">%Y.%m.%d %H:%M</li>
<li class="mono">%Y.%m.%d</li>
<li class="mono">%Y%m%d%H%M%SED</li>
<li>Integer timestamp in seconds after or before the epoch (1970-1-1)</li>
</ul>
<p>The layer list contains all layers managed by Time Manager.
To add a vector layer, press [Add layer].
To add a raster layer, press [Add raster].
If you want to remove a layer from the list, select it and press [Remove layer].</p>
<p>Below the layer list, you'll find the following <b>animation options</b>:</p>
<p><b>Show frame for x milliseconds</b>...
allows you to adjust for how long a frame will be visible during the animation</p>
<p><b>Play animation backwards</b>...
if checked, the animation will run in reverse direction</p>
<p><b>Display frame start time on map</b>...
if checked, displays the start time of the visible frame in the lower right corner of the map</p>
<h2>Add Layer dialog</h2>
<p>Here, you are asked to select the layer that should be added and specify the columns containing
start and (optionally) end time.</p>
<p>The <b>offset</b> option allows you to further time the appearance of features. If you specify
an offset of -1, the features will appear one second later than they would by default.</p>
<h2>Dock widget</h2>
<p>The dock was designed to attach to the bottom of the QGIS main window. It offers the following tools:</p>
<ul>
<li><img src="images/power_on.png" alt="power"/> ... On/Off switch, allows you to turn Time Manager's functionality on/off with the click of only one button</li>
<li><span class="hidden">[Settings]</span><input type="button" value="Settings"/> ... opens the Settings dialog where you can manage your spatio-temporal layers</li>
<li><span class="hidden">[Export Video]</span><input type="button" value="Export Video"/> ... exports an image series based on current settings (This button is only enabled if there are layers registered in Time Manager "Settings")</li>
<li><b>Time frame start: <span class="hidden">[2000-01-01 00:00:00]</span></b><input type="text" value="2000-01-01 00:00:00"/> ... shows the start time of the currently active frame. Allows you to precisely specify your desired analysis time.</li>
<li><b>Time frame size: </b><input type="text" value="1"/><span class="hidden">[x]</span><select><option value="days">days</option></select> ... allow you to choose the size of the time frame</li>
<li><img src="images/back.png" alt="back"/> ... go to the previous time frame</li>
<li><img src="images/forward.png" alt="forward"/> ... go to the next time frame</li>
<li><b>Slider</b> ... shows the position of current frame relative to the whole dataset and allows you to seamlessly scroll through the dataset</li>
<li><img src="images/play.png" alt="play"/> ... start an automatic animation based on your current settings</li>
</ul>
