🗺️ What is Digitizing in GIS?
Digitizing is a fundamental GIS process where real-world features are converted into digital map data by tracing them from satellite images, aerial photos, or scanned maps.
📌 Why is Digitizing Important?
✔ Converts raw imagery into usable spatial data
✔ Helps in creating accurate maps for analysis
✔ Essential for urban planning, disaster management & environmental studies
📌 Types of Digitizing:
🔹 Point → Wells, trees, landmarks
🔹 Line → Roads, rivers, pipelines
🔹 Polygon → Buildings, land use areas, lakes
📌 How it works:
1️⃣ Load satellite image (e.g., Google Earth)
2️⃣ Create a new layer in GIS software
3️⃣ Trace features manually using tools
4️⃣ Save as shapefile or GeoJSON
📌 Popular Tools:
✔ QGIS
✔ ArcGIS
