Flight safety starts long before the drone ever takes off.

One of the most important parts of mission planning is understanding how the terrain around you can affect your operation. How can you be sure that, while conducting a survey, you won't suddenly lose signal because of a ridge, hill, or other terrain obstacle?

In this video, I demonstrate how viewshed analysis can be used during the planning phase to identify potential line-of-sight limitations before arriving on site. By understanding the terrain in advance, RPA operators can make better decisions, improve safety, and reduce the risk of unexpected signal loss during flight.

Good planning isn't just about efficiencyโ€”it's an essential part of safe RPA operations.

Someone recently asked how it is possible to produce ๐จ๐ซ๐ญ๐ก๐จ๐ฆ๐จ๐ฌ๐š๐ข๐œ๐ฌ, ๐ƒ๐ข๐ ๐ข๐ญ๐š๐ฅ ๐„๐ฅ๐ž๐ฏ๐š๐ญ๐ข๐จ๐ง ๐Œ๐จ๐๐ž๐ฅ๐ฌ (๐ƒ๐„๐Œ๐ฌ), ๐š๐ง๐ ๐Ÿ‘๐ƒ ๐ฉ๐จ๐ข๐ง๐ญ ๐œ๐ฅ๐จ๐ฎ๐๐ฌ using a consumer drone.

The short answer is: ๐ญ๐ก๐ž๐ฒ ๐œ๐š๐ง ๐š๐›๐ฌ๐จ๐ฅ๐ฎ๐ญ๐ž๐ฅ๐ฒ ๐›๐ž ๐ฉ๐ซ๐จ๐๐ฎ๐œ๐ž๐ ๐ฐ๐ข๐ญ๐ก ๐œ๐จ๐ง๐ฌ๐ฎ๐ฆ๐ž๐ซ ๐๐ซ๐จ๐ง๐ž๐ฌ. The differences lie more in efficiency, workflow, and the level of accuracy required than in whether it is possible at all.

Here's a bit of an explanation:

Important distinction that is often overlooked is the difference between geometric accuracy and absolute positional accuracy.
Enterprise drones equipped with RTK, high-end cameras, and, where applicable, LiDAR are designed to produce highly accurate survey data. Their superior optics, larger sensors, accurate positioning, and professional workflows allow them to produce excellent results, often with fewer flights than a consumer drone.

Naturally, if you apply that same optimized workflow to an enterprise drone, it will generally produce even better results because it starts with higher-quality data.

In other words, if your goal is the most accurate geographic positioning possible, well-surveyed GCPs are still the gold standard.
Another major advantage of enterprise drones is their camera hardware. A typical 4/3-inch sensor has a surface area of approximately 225 mmยฒ, compared with about 116 mmยฒ for a 1-inch sensor. That gives the 4/3 sensor nearly twice the light-collecting area, resulting in better dynamic range, lower image noise, and improved image quality, particularly under less-than-ideal lighting conditions.

Enterprise cameras also generally feature higher-quality lenses with better sharpness, lower distortion, reduced chromatic aberration, and more consistent image quality across the frame.

These improvements allow you to fly faster while maintaining image quality. If the drone is equipped with LiDAR, it gains an additional advantage because LiDAR actively measures distances using laser pulses and is largely unaffected by shadows or poor surface texture. This allows reliable data collection in situations where photogrammetry may struggle, such as dense vegetation or low-texture surfaces.

Overall, enterprise systems allow survey work to be completed faster and under more challenging conditions.

An enterprise drone will generally produce cleaner imagery and more robust datasets, particularly under difficult conditions, but under good conditions the practical difference may only become noticeable when examining the imagery at very high zoom levels or in challenging environments.

The biggest advantage of enterprise equipment is productivity.
What might take a consumer drone many hours of flying and careful planning can often be completed much faster with an enterprise system because of RTK, superior cameras, automated workflows, and, where applicable, LiDAR.

One thing, however, does not change regardless of what drone you fly: if your client requires survey-grade absolute accuracy, someone still has to establish or verify GCPs on the ground. Enterprise drones reduce field time, but they do not eliminate the need for proper survey control.

Suppose an employee costs US$3 per hour, and a two-person survey crew using a Mini requires about six hours to collect the data needed for each project. Over 240 working days per year, that's approximately 2,880 labor-hours, or around US$8,640 in annual labor costs.

Now assume an enterprise drone allows the same work to be completed ten times faster. Your annual labor cost drops to roughly US$864.

Over two years, that's approximately US$17,280 in labor using the Mini workflow versus about US$1,728 using the enterprise workflow.

Even after purchasing a US$15,000 enterprise drone, you've essentially recovered your investment in around two years through labor savings alone.

Many people tell me they're interested in mapping, but they're afraid of making mistakes or think it's too complicated to get started.

In this video, I explain why it doesn't have to be complicated and show a very simple example of how anyone can make their first map edit.

In fact, when my sons were 6-year-old, they learned the basics surprisingly quickly under my supervision. If they can do it at that age, chances are good you can too.

๐Ÿ“DGPS vs RTK vs PPK โ€“ Which GNSS Surveying Method is Best?

Choosing the right positioning technology is essential for achieving accurate survey results. DGPS (Differential GPS) provides sub-meter accuracy using real-time code corrections, making it suitable for road construction, hydrographic surveys, and general mapping. It is cost-effective but less precise than RTK and PPK.

RTK (Real-Time Kinematic) delivers 1โ€“5 cm accuracy through real-time carrier-phase corrections from a nearby base station or CORS network. It is widely used in land surveying, civil engineering, construction layout, drone mapping, and machine control. RTK requires a continuous communication link throughout the survey.

PPK (Post-Processed Kinematic) also achieves centimeter-level accuracy, but corrections are applied after fieldwork using recorded GNSS data. Since it doesn't require a live correction signal during data collection, it is ideal for drone surveys, remote locations, forests, mountainous terrain, and areas with poor network coverage.

Quick Comparison:

DGPS: 0.5โ€“2 m accuracy, economical, real-time, general surveying.

RTK: 1โ€“5 cm accuracy, real-time, requires continuous correction signal.

PPK: 1โ€“5 cm accuracy, post-processed, excellent for signal-challenged environments.

Understanding these technologies helps engineers and surveyors choose the most efficient method for their project based on accuracy, cost, and field conditions.

Establishing GCPs in rural or difficult-to-access terrain can be time-consuming, especially when you're carrying GNSS equipment and are unsure whether a footway, path, track, or set of steps actually leads to your intended location.

A practical approach is to plan ahead by first conducting a quick, low-detail, low-accuracy RPA survey to produce an orthographic overview of the area. While not suitable as a final mapping product, this preliminary orthomosaic provides valuable situational awareness, helping you identify access routes, terrain obstacles, and suitable GCP locations before heading into the field.

A small investment in reconnaissance can save significant time, effort, and unnecessary fieldwork.

I was recently asked by one of our BCPO officers PS9 about the no-fly zones in and around Baguio.

While the Civil Aviation Authority of the Philippines (CAAP) does not currently provide an official no-fly zone map, I quickly created a simple reference map using QGIS to give a general visual representation.

If you intend to operate a remotely piloted aircraft (RPA) in or near a no-fly zone, I strongly recommend ๐œ๐จ๐จ๐ซ๐๐ข๐ง๐š๐ญ๐ข๐ง๐  ๐ฐ๐ข๐ญ๐ก ๐‚๐€๐€๐ beforehand to ensure compliance with applicable regulations and to avoid any unnecessary legal issues.
