The following geophysical data layers are included in this service:<\/font><\/span><\/p>
Total Magnetic Intensity<\/strong><\/span> - <\/span>Georeferenced Image of Total Magnetic Intensity. Pink represents high magnetic intensity, while blue represents background fields, low magnetic values, or zones of strongly reversed polarity.<\/font><\/li>
Reduced-to-pole Magnetic Intensity<\/strong><\/span> - <\/span>Georeferenced Image of Reduced-to-pole Magnetic Intensity. Pink represents high magnetic intensity, while blue represents background fields, low magnetic values, or zones of strongly reversed polarity.<\/font><\/li>
First Vertical Derivative<\/strong><\/span> - <\/span>Georeferenced Image of First Vertical Derivative. Pink highlights strong magnetic boundaries and shallow structures, while blue represents low values and background fields.<\/font><\/li>
Ternary (K, eTh, eU<\/strong><\/span>) -<\/span> Georeferenced Image of Radiometric Ternary map. Red = Potassium, Green = Thorium, Blue = Uranium. <\/span><\/font><\/li>
Potassium (K)<\/strong><\/span> - <\/span>Georeferenced Image of Radiometric Potassium map. Pink is high, blue is low potassium concentration.<\/font><\/li>
Thorium (eTh)<\/strong><\/span> - <\/span>Georeferenced Image of Radiometric Thorium map. Pink is high, blue is low thorium concentration.<\/font><\/li>
Uranium (eU)<\/strong><\/span> - <\/span>Georeferenced Image of Radiometric Uranium map. Pink is high, blue is low uranium concentration.<\/font><\/li><\/ul>
Data downloaded from USGS have in some cases been minimally modified (e.g., clipped to spatial extent, projected, shaded) but have not been formally reviewed or altered by the WSGS. Users are encouraged to visit the USGS data release to download the original dataset.<\/span><\/div>
