Overview
This project involves capturing and processing drone imagery to generate a DSM and conceptual contour visualization of a municipal park using WebODM and QGIS. Deliverables are for portfolio development and are not certified survey products.
Objectives
Plan and execute an aerial flight over the park using a DJI drone
Capture high-resolution, overlapping RGB imagery
Process imagery into an orthomosaic and DSM using WebODM
Use QGIS to generate and style 2D contour lines
Tools & Methods
DJI Mavic Series – image capture
WebODM – photogrammetry, DSM, orthomosaic generation
QGIS – GIS analysis, contour creation, cartographic styling
Results
Orthomosaic map (GeoTIFF)
Digital Surface Model (DSM)
Contour shapefile with elevation intervals
Screenshot maps and exports for visualization
