Isarithmic Mapping: Washington Annual Precipitation

 

The core of this project utilized the PRISM interpolation method, which incorporates physiographic factors such as elevation and topographic orientation to predict precipitation values. This method proved to be invaluable, especially in areas with varied terrain, providing an understanding of how the geography of an area influences its climate.

My map was enhanced by techniques like hypsometric tinting and continuous tone symbology. Hypsometric tinting was particularly useful in depicting elevation, while continuous tones smoothly illustrated the gradation of precipitation levels. This approach not only aids in professional meteorological studies but also serves utility companies and urban planners in managing water resources and infrastructure planning.
