1. Core Functionalities of Drone Spraying Software
   Drone spraying software acts as the operational backbone of aerial application systems, combining automation, precision, and compliance tools. Its key features include: a. Mission Planning and Navigation

• 3D Mapping: Generates detailed field maps using satellite imagery or LiDAR data to identify terrain, crop health zones, and restricted areas.
• Flight Path Automation: Designs optimized routes for drones, ensuring full coverage with minimal overlaps and adherence to no-fly zones.
• RTK/PPK GPS Support: Ensures centimeter-level accuracy for precise nozzle control and compliance with regulatory buffer zones. b. Smart Spraying Controls
• Variable Rate Application (VRA): Dynamically adjusts spray flow rates based on real-time data, such as crop density or soil moisture, to minimize chemical waste.
• Obstacle Avoidance: Integrates with onboard sensors (e.g., cameras, LiDAR) to navigate physical obstructions and avoid off-target spraying.
• Weather Adaptation: Monitors environmental conditions (wind, humidity, temperature) to pause operations during unfavorable scenarios. c. Data Integration and Analytics
• IoT Connectivity: Syncs with soil sensors, weather stations, and farm management systems for data-driven decision-making.
• Spray Monitoring: Tracks chemical usage, droplet size, and coverage efficiency through real-time dashboards and post-operation reports.
• AI-Driven Insights: Identifies pest hotspots, nutrient deficiencies, or disease outbreaks using multispectral or thermal imagery. d. Compliance and Reporting
• Regulatory Alerts: Notifies operators of airspace restrictions, pesticide application deadlines, or no-spray zones.
• Audit Trails: Generates logs of flight paths, spray times, and chemical volumes for regulatory compliance and certification processes.
