Reservoir Characterization Map: A topographic map of an area, with various colors used to represent different elevations and features. The colors range from orange in the lower left corner to teal in the upper right corner, with red, pink, purple, blue, and other colors in between. The map appears to be of a mountainous region, with many peaks and valleys visible. There are also several bodies of water present on the map, including lakes and rivers. In the center of the image, there is a large body of water that resembles a lake or reservoir. This lake is surrounded by land that has been colored pink and red, suggesting that it may be an area of interest for geochemical analysis. To the left of the lake, there appears to be a river or stream running through the landscape. The map also includes several symbols and markings, which are likely used to indicate different features such as roads, trails, and landmarks. Overall, the image suggests that this is a topographic map created using geospatial data analysis techniques, specifically designed for reservoir characterization via geochemistry.
