Efficient interpolation for isohyetal maps
Understanding rainfall patterns becomes easier when a computer handles the points and plots the map at your chosen scale. This book shows how to translate rain-gage data into accurate, publication-ready isohyetal maps with a simple linear interpolation approach.
The text explains the computer program’s structure and workflow—from data checks to coordinates calculation and final plotting. It covers the interpolation network, handling multiple diagonals, and how the program can include or exclude interpolated points. You’ll see how input data are organized, how results are produced, and what the output looks like, including maps and tables.
- How linear interpolation is applied along lines between neighboring stations
- How the program manages networks, diagonals, and extrapolation
- The three divisions: data examination, data rearrangement, and plotting
- Practical examples and how to read the map output and accompanying tables
Ideal for readers of hydrology, watershed analysis, and geographic plotting, this edition explains both the method and its real-world results.
