Understanding the nuances of commercial property assessment has historically been a complex and time-consuming process. Before the digital age, professionals relied on physical site visits, manual measurements, and paper-based records to evaluate properties. This not only limited the speed and scope of assessments but also introduced a high potential for human error. In the era before widespread data availability, insights into property conditions, such as the state of the roof, window conditions, and access to buildings, were hard to come by. The reliance on antiquated methods meant that significant changes or damages could go unnoticed for extended periods, affecting valuation accuracy and investment decisions.

The advent of sensors, the internet, and connected devices has revolutionized the way we gather and analyze data on commercial properties. The proliferation of software and the move towards digitizing every event have made it possible to access detailed property insights in real-time. This shift has not only improved the accuracy of property assessments but has also significantly reduced the time required to obtain actionable insights.

The importance of data in understanding commercial properties cannot be overstated. Previously, professionals were in the dark, waiting weeks or months to understand changes in property conditions. Now, with the help of advanced data collection methods, changes can be understood in real-time, allowing for more informed decision-making and investment strategies.

Among the most transformative data types in this field are satellite imagery and real estate data. These datasets provide a bird's eye view of properties, offering insights that were previously impossible to obtain without physical presence. The following sections will delve into these data types, exploring their history, examples, and how they can be leveraged to gain better insights into commercial property assessment.

Satellite Data

History and Evolution

Satellite imagery has come a long way since the first Earth-observing satellite was launched in the 1960s. Initially used for environmental monitoring and military surveillance, the application of satellite data has expanded to include commercial property assessment. Technological advances have improved the resolution of satellite images, allowing for the detection of objects as small as passenger cars and large trees. This has opened up new possibilities for assessing property conditions from a top-down perspective.

Examples and Uses

Modern satellite data providers offer imagery with resolutions ranging from 1.5m to 5m, enabling the assessment of vegetation, access to buildings, and physical boundaries. While limitations exist in assessing roof or window conditions directly, satellite data can still provide valuable insights into property layouts, the presence of large trees, and potential hazards such as electricity pylons.

Applications of satellite data in commercial property assessment include:

  • Vegetation assessment: Identifying large trees that may pose risks to property structures.
  • Access analysis: Evaluating the accessibility of buildings for potential developments or emergency response planning.
  • Boundary identification: Determining the presence of physical boundaries such as fences and walls that may affect property valuation.
  • Catastrophe assessment: Rapidly assessing damage from natural disasters to inform insurance claims and recovery efforts.

Technology Advances

The integration of computer vision algorithms and machine learning with satellite imagery has enhanced the ability to automatically detect and classify objects within images. This has significantly increased the efficiency and accuracy of property assessments, reducing the need for manual analysis.

Real Estate Data


Real estate data encompasses a wide range of information related to properties, including satellite imagery services. This data type provides real-time images of specific locations anywhere in the world, offering a comprehensive view of commercial properties.


Real estate data can be used to:

  • Monitor property conditions: Keeping track of changes in property conditions over time.
  • Assess property features: Evaluating features such as roof material, building height, and property type (commercial or residential).
  • Support investment decisions: Providing detailed property insights to inform investment strategies and valuation.

Technology Integration

The use of platforms like Nearmap, Maxar, and Airbus has facilitated access to up-to-date satellite imagery, enabling more accurate and timely property assessments. The integration of these technologies with real estate data platforms has streamlined the process of obtaining and analyzing property information.


The importance of data in commercial property assessment cannot be overstated. The advent of satellite and real estate data has transformed the way professionals understand and evaluate properties. These data types offer unprecedented insights into property conditions, enabling more informed decision-making and investment strategies.

As organizations become more data-driven, the ability to discover and leverage diverse data types will be critical to success. The future of commercial property assessment lies in the continued advancement of data collection and analysis technologies, including the potential for AI to unlock value from decades-old documents and modern government filings.

Corporations are increasingly looking to monetize useful data that they have been creating for decades. The field of commercial property assessment is no exception, and we can expect to see new types of data being sold in the future, providing additional insights into property conditions and valuation.


Industries and roles that could benefit from satellite and real estate data include investors, consultants, insurance companies, and market researchers. These professionals face challenges in accurately assessing property conditions and values, and data has transformed their ability to make informed decisions.

The future of commercial property assessment is bright, with AI and machine learning poised to unlock even greater insights from data. As technology continues to evolve, the value hidden in historical documents and modern filings will become increasingly accessible, driving innovation and efficiency in the industry.
