Choropleth Graph

• A choropleth chart is a thematic chart in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the graph.

• Since we have many measurements such as NDVI, NDWI, NDMI, BSI and AVI, we use Choropleth to represent these measurements on the graph.

• In order to relate each measurement with its actual meaning, we select appropriate color to show on the Graph.

• For example, NDVI represent the health of plants so we choose to use Divergence of Orange and Green.

• Blue for Water, brown for soil, so on and so forth.
