Their ability to operate in constellations enhances data coverage and revisit rates, offering a dynamic and responsive approach to monitoring changes on Earth's surface. The advancements in miniaturized sensors and imaging technologies aboard these satellites contribute to high-resolution and real-time data acquisition, making them valuable tools for a variety of scientific and commercial purposes. They work they do side by side with larger satellites like Landsat or Sentinel, to help accentuate data collection, by not having to rely on the bigger satellites as frequently.

The adoption of drones for mapping and surveying using high-resolution cameras and LiDAR sensors is rapidly increasing. The ability to quickly deploy and cover hard-to-reach areas, whilst not compromising on the data quality, is one of the biggest advantages, followed by the lower cost of utilisation and the lack of carbon emissions if using all-electric systems. Unfortunately, regulations are holding back the potential of drones in this sector, as most operators are limited to the extent they can fly and the areas they can cover i.e. urban areas. It's also worth noting, that the correct qualifications should be required if you are collecting and analysing important datasets used for mapping.

This is quite fascinating! I recently launched a tech podcast called Geohabari, and in this week's episode I had a very insightful conversation with a GeoAI Engineer and where he seats within what I like to refer to as the Remote Sensing Matrix. A few takeaways from that conversation: - AI is definitely having a moment without which the construction of highly accurate models through deep learning would have been unimaginable. - UAVs, along with the concurrent deployment of these deep learning models, collectively generate such a wide array of use cases and endless possibilities. - It's intriguing to witness how these advancements have revolutionised tasks and processes that were once inconceivable.

Drones are also making it possible to collect data that traditionally would have taken longer, at a higher cost in resources, and at a lower data quality. For example, for utility power pole inspections drones can document a power pole and the electrical components at a resolution and view angle that only a human on a bucket lift truck could attain alternatively. All while being faster, safer, more cost effective, and with a high resolution dataset that can be stored for future review.

Drone mapping is evolving in various industries, carrying multiple types of sensors and other payloads. It helps to achieve high-resolution, near-real-time, and accurate data on-demand with flexibility of angle for data capture.

Drone Mapping is revolutionizing the way we perceive and interact with our physical environment. Drones can generate high-resolution data. They are unlocking unprecedented levels of precision in mapping and analysis. From land use planning and infrastructure monitoring to agriculture and environmental conservation, the utility of drones is expanding across a multitude of domains. Drones are potent tools in the field of remote sensing. With their flexibility in operation and high-resolution data collection capabilities, drones are redefining the landscape of spatial analysis. However, the more data they generate the greater the need for the incorporation of additional technologies such as artificial intelligence and cloud computing.

AI and ML are quite a match made in heaven and how their combination can lead to great insights when discovering trends in remote sensing data. They can be used to create deep-learning models for precise classification, especially in vegetation. Example you could create a deep learning model that can be used to distinguish coconut trees from other vegetation and trees and proceed to count the number of trees present in your AOI. Let's embrace AI and take advantage of its capabilities
