74				<h3 class="about-header">Overview</h3>
75				<p>LanDAT is a vegetation monitoring tool for assessing whether landscape change is leading to de

75sirable outcomes, and for understanding landscape resilience in a quantitative and integrative way.</p>
76				<p>The map viewer lets users explore regularly updated data and graphical information describing landscape dynamics over short and long terms.</p>
77				<p>LanDAT works from the premise that measuring and interpreting these dynamics improves informed decision-making in natural resource management and ecosystem service conservation.</p>
78				<h3 class="about-header">Map Layers</h3>
79				<p>This section lets users view landscape information on the map &mdash; both LanDAT datasets and ancillary layers from other providers (in addition to reference maps; ancillary landscape data are located in the ‘Landscape and Climate Characteristics’ group).</p>
80				<ul class="about-list">
81				  <li>To put a layer on the map click the checkbox next to its label.</li>
82				  <li>To expand or collapse a group of related layers click the group's bar.</li>
83				  <li>To view a layer's description click <img src="imgs/more-info-icon-64x64.png" class="about-icon" alt="Representative descriptive icon" title="Representative descriptive icon">.</li>
84				  <li>To adjust a layer's transparency move the slider marked by <img src="imgs/opacity-icon-closed-64x64.png" class="about-icon" alt="Representative transparency icon" title="Representative transparency icon">.</li>
85				</ul>
86				<h3 class="about-header">Vegetation Index Graphs</h3>
87				<p>This section visualizes the change over time in vegetation greenness &mdash; the Normalized Difference Vegetation Index (NDVI) &mdash; at locations you specify.</p>
88				<p>NDVI data are gathered daily by two satellite-based moderate resolution sensors (MODIS). These daily data are filtered and smoothed to generate an 8-day composite time series that spans the peri

88od of MODIS record from 2000 until present*.</p>
89				<p>The LanDAT map layers quantify annual and multi-annual phenological patterns present in these data**. (See our detailed <a href="https://unca.maps.arcgis.com/apps/MapJournal/index.html?appid=ed63f137bb474972a4acb0df32f46e6d" target="_blank">Overview</a> for more information).</p>
90				<ul class="about-list">
91				  <li>To create a graph for a location, click the location on the map.</li>
92				  <li>To center the map on a graph's location, click the "Show On Map" button.</li>
93				  <li>To scroll the list of graphs to an existing location's marker &mdash; <img src="imgs/blue_icon.png" class="about-icon" alt="Representative map marker" title="Representative map marker"> &mdash; click that marker on the map.</li>
94				  <li>To remove a graph and its marker, click <img src="imgs/close-icon.png" class="about-icon" alt="Representative close button" title="Representative close button">.</li>
