Delivering Professional Results
Why It Matters
You can fly perfectly and process flawlessly, but if your client experience is sloppy, you will not get called back. The surveyors who win repeat contracts do so because they deliver consistent, professional results from first contact through final file handoff. That consistency comes from systems, not talent.
Pre-Flight Checklist for Surveying Missions
Before you leave the shop, verify:
- Battery count: Minimum 6 charged batteries for a 40-acre site at 80% overlap
- Memory cards: 2+ cards, formatted, 128GB minimum each
- GCPs: Minimum 5 for sites under 50 acres, plus 1 per additional 20 acres
- Base station (if using RTK): Firmware updated, known coordinate loaded
- Equipment log: Camera lens clean, gimbal calibrated within past 30 days
- Site access: Gate codes, POC phone number, parking instructions confirmed
Field Workflow
Arrive and Assess (15 minutes): Walk the site perimeter. Look for new obstacles, check for active machinery, identify no-fly zones near the boundary.
Set GCPs (20-40 minutes): Place at corners and center. Avoid slopes exceeding 15 degrees, metal fences, or tree canopy. Photograph each GCP location.
Fly the Mission: Execute your planned flight path. Monitor battery voltage and signal strength. If you notice anomalies, complete the mission and re-fly the affected section.
Verify Data On-Site: Check images on a tablet before packing up. Look for blur, missing overlap, sun glare, and incomplete flight paths. Re-fly problem sections while you are still on site.
Pack Up: Collect all GCPs. Account for every piece of equipment.
Data Backup: The 3-2-1 Rule
- 3 copies of your data
- 2 different storage types (SSD, HDD, cloud)
- 1 offsite location (cloud storage or physical drive stored elsewhere)
Back up raw files before processing. Never process from your only copy. A corrupted SD card on a 200-acre survey costs $2,000-4,000 to reshoot, plus the client relationship.
Processing Quality Control
After processing, run through these checks:
- Geometric accuracy: Compare at least 3 GCP locations to known coordinates. RMSE should be within your stated tolerance (typically 2-5 cm for RTK surveys)
- Visual inspection: Scroll through the orthomosaic at 100% zoom for stitching artifacts, blur, and color issues
- Elevation verification: Check known elevation points against your DEM
- Completeness: Verify no data gaps, especially along flight path edges
Report Template
Every deliverable should include:
- Project summary: Date, location, weather, equipment, flight parameters
- Accuracy statement: Methodology, expected accuracy, RMSE values
- Deliverables list: Files included with formats and resolutions
- Limitations: Areas of reduced accuracy
- Coordinate reference system: Datum, projection, vertical datum
- GCP documentation: Location photos, coordinates, placement notes
Client Communication
Send three touchpoints minimum:
- Pre-flight confirmation: 24 hours before, confirm access and weather backup date
- Field completion update: Same day, confirm data collection is complete
- Delivery notification: Include accuracy statement and limitations upfront
Quick Check
Q: How many GCPs should you place on a 70-acre survey site? A: Minimum 8 (5 base + 1 per additional 20 acres = 5 + 3 = 8)
Q: What does the 3-2-1 backup rule require? A: 3 copies of data, on 2 different storage types, with 1 copy offsite.
Q: Why verify data on-site before leaving? A: Reshooting a problematic section while still on-site costs minutes. Returning days later costs hours, money, and client trust.
