Welcome to our RU-vid tutorial on estimating the surface volume of a lake using ArcGIS! 🌊 If you're a GIS enthusiast or a water resource manager looking to analyse and understand the water bodies in your area, you've come to the right place.
In this video, we'll walk you through a step-by-step guide on how to harness the power of ArcGIS, a leading geospatial software, to accurately calculate the volume of a lake. You'll learn about the necessary tools, techniques, and data sources, so whether you're working on environmental research, urban planning, or simply satisfying your curiosity, you'll gain valuable insights.
Here's what you can expect to learn:
📌 Introduction to ArcGIS and its capabilities in hydrology
📌 Data preparation: acquiring digital elevation models (DEMs) and Landsat 8 data
📌 Building a comprehensive workflow for lake surface volume calculation
📌 Using the 3D Analyst and Spatial Analyst tools effectively
📌 Interpretation and visualization of your results
