Slope Map Preparation in ArcGIS 10.8 | Step-by-Step Slope Analysis Tutorial for Beginners (2025)

Welcome to Part 1 of the Slope Map Making Series!
In this video, you’ll learn how to prepare a slope map in ArcGIS 10.8 — step by step, from data preparation to final map layout. This beginner-friendly tutorial will help you understand each process clearly, including projection changes, raster clipping, slope generation, reclassification, and area calculation.

🔹 What You’ll Learn in This Video:
1️⃣ Prepare your study area shapefile and visualize the data
2️⃣ Download and import DEM (Digital Elevation Model)
3️⃣ Change coordinate system from GCS to PCS
4️⃣ Project raster and clip the study area
5️⃣ Generate and reclassify slope categories
6️⃣ Calculate slope area and export results
7️⃣ Create a professional slope map layout in ArcGIS
