Geospatial Soil Sampling Planner

Client Objective

Agronomists needed a way to convert hand-drawn field boundaries into systematic, optimized soil sampling plans. The goal was to automate the planning process — from boundary digitization to generating sampling point coordinates — reducing manual work and ensuring consistent, scientifically sound sampling strategies.

Challenges

• → Geospatial accuracy: Ensuring precise coordinate mapping from hand-drawn inputs
• → Complex boundaries: Handling irregular field shapes and multi-polygon areas
• → Performance: Processing large field datasets without lag
• → Usability: Making complex geospatial planning accessible to non-technical users
• → Interoperability: Exporting to formats compatible with field equipment and lab systems

DAAF's Approach

We developed a geospatial planning module that automates the entire workflow from boundary input to sampling plan generation. Our solution includes:

• → Intelligent boundary digitization and validation
• → Adaptive sampling algorithms (grid-based, zone-based, random stratified)
• → Constraint handling (exclusions, buffer zones, accessibility rules)
• → Multi-format export (Shapefile, KML, CSV, PDF maps)

Solution Snapshot

Key components of the developed module:

• → Boundary Tools: Draw, upload, or import field boundaries with validation
• → Sampling Strategies: Grid, zone-based, or custom pattern selection
• → Constraints: Define exclusion zones, buffer areas, and accessibility rules
• → ID & Labeling: Automatic point numbering and custom label generation
• → Exports: Shapefile, KML, CSV coordinates, and printable PDF maps

Outcomes

Measurable benefits achieved:

• → Consistency: Standardized sampling plans across all fields
• → Speed: Plans generated in seconds instead of hours
• → Accuracy: Geospatial precision ensures reliable field navigation
• → Operational Fit: Seamless integration with existing field and lab workflows
