             <p>Drag the handle to adjust the minimum tree cover canopy (TCC) density for Hansen/UMD/Google/USGS/NASA tree cover and tree cover loss displayed in the graphs and rankings. TCC density represents the estimated percent of a pixel that was covered by tree canopy in the year 2000, as determined from the analysis of satellite imagery. For the tree cover loss data, TCC density therefore corresponds to the density of tree cover <u>before</u> loss occurred.</p>
  -          <p>Adjustments to the minimum TCC density will only affect Hansen/UMD/Google/USGS/NASA tree cover and tree cover loss. This feature does not pertain to Hansen/UMD/Google/USGS/NASA tree cover gain or to other GFW data layers or statistics. Hansen/UMD/Google/USGS/NASA tree cover gain is displayed with a set minimum TCC density greater than 50%.</p>
  -          <p>This feature is also available for the map visualization, analysis, and for individual country profiles. The TCC density minimum selected for the overview graphs and rankings will not be applied automatically to other areas of the website.</p>

positive.code:         <p>The graph and rankings visualize tree cover data from Hansen/UMD/Google/USGS/NASA. Due to variation in research methodology and/or date of content, this data cannot be compared accurately against tree cover loss and gain. Accordingly, current (or post-2000) tree cover cannot be determined by subtracting annual tree cover loss from year 2000 tree cover.  For more information on this data set, please visit the <a href="http://data.globalforestwatch.org/datasets/7876b225f8034a0ebba79fad4afb80ad" target="_blank">Open Data Portal</a>.</p>
  
          <p>Please also note that “tree cover” does not equate to “forest cover.” “Tree cover” refers to the biophysical presence of trees, which may be a part of natural forests or tree plantations.</p>
