Data and information management is fundamental for land survey professionals to ensure precise and reliable project outcomes. In Kenya, where land disputes and development projects hinge on accurate land data, understanding how to handle data and convert it into meaningful information is critical. This chapter explores the core concepts of data and information, their relevance in land surveying, and how surveyors can leverage these resources to enhance decision-making, reporting, and compliance with regulatory requirements.
In the context of land surveying, distinguishing between data and information is essential because each plays a distinct role in the survey process. Data refers to raw, unprocessed facts collected from the field, while information is the refined, interpreted output that supports analysis and decision-making. Grasping these concepts enables surveyors to handle field measurements, map coordinates, and legal descriptions effectively, transforming them into actionable insights for clients and government agencies.
Data consists of raw, unorganized facts or figures collected during land surveying activities. This includes measurements such as distances, angles, elevations, GPS coordinates, and photographs taken on site. For example, a surveyor measuring the boundary of a parcel of land records numerical values from a total station or GPS receiver; these values constitute data before any analysis. Data by itself lacks context and meaning until it is processed or interpreted.
Information is data that has been processed, organized, or structured to have meaning and relevance for a specific purpose. In land surveying, this could be a cadastral map, a survey report, or a topographic model created by analyzing raw data. Information supports decision-making, such as determining land ownership boundaries or planning construction layouts. Without converting data into information, survey results would be unintelligible to stakeholders like county land registries or property developers.
Understanding the distinction between data and information clarifies their roles in the surveying workflow. Data is unprocessed, while information is processed and contextualized. Data requires validation and analysis to become useful; information is the end product that aids understanding. For instance, GPS coordinates (data) become information when plotted on a map to show a land parcel’s exact location. This transformation is vital for legal documentation and dispute resolution.
Land surveyors encounter various data types that must be accurately recorded and managed. These include numerical data (distances, angles), spatial data (coordinates, elevations), textual data (notes, descriptions), and visual data (photographs, sketches). Each type requires different tools and techniques for collection and processing. For example, spatial data collected via drones or GPS devices is critical for creating digital maps and geographic information system (GIS) databases used by county governments.

It examined the different types of internet services such as communication, information retrieval, file transfer, web services, and ecommerce, illustrating how these services support digital interaction and business activities. The discussion then moved to types of internet access applications, emphasizing their role in connecting users to online resources. Key web browsing concepts were introduced alongside essential security and safety considerations to protect users while navigating the internet. Practical aspects of web browsing covered the use of browsers, managing tools and settings, clearing cache and cookies, understanding URIs, and organizing bookmarks to enhance user experience. The chapter also addressed web-based information management, focusing on effective search techniques, critical evaluation of online content, and the importance of copyright and data protection. Finally, it covered the management of downloads, strategies for performing digital data backups both online and offline, and concluded with emerging issues in internet technology that influence how data and information are handled today.
