Bathymetry Data Analysis in Lake Sarangan: From Raw Data to Visualization in R -part 1

In this video, I walk you through the complete process of analyzing bathymetry data from Telaga Sarangan (Lake Sarangan), Magetan, East Java, Indonesia. We'll start by loading and preparing the spatial data, including shapefiles for the lake, roads, and rivers. Then, we'll dive into processing bathymetry data using R, performing IDW (Inverse Distance Weighting) interpolation, and creating beautiful visualizations of the depth zones.

Here's what you'll learn:

How to load and clean spatial data in R using sf and dplyr.
How to plot bathymetry data on a map using ggplot2.
Step-by-step guide on performing spatial interpolation using IDW.
Classifying depth zones (shallow, medium, deep) based on the interpolated data.
Visualizing the depth distribution with pastel colors and creating a histogram of depth categories.
