karttatietoaineistossa

Karttatietoaineisto refers to the data used in cartography and geographic information systems. It encompasses a wide range of digital information that describes the Earth's surface and its features. This data can include vector data, which represents geographic features as points, lines, and polygons (e.g., roads, rivers, buildings), and raster data, which represents geographic features as a grid of pixels, often used for imagery like satellite photos or elevation models.

The collection and management of karttatietoaineisto are crucial for various applications, including urban planning, environmental monitoring, navigation, emergency response, and resource management. Data sources can be diverse, including aerial photography, satellite imagery, GPS surveys, existing maps, and sensor networks. Accuracy, currency, and completeness are key quality attributes for karttatietoaineisto.

Geographic Information Systems (GIS) are software systems designed to capture, store, manipulate, analyze, manage, and present all types of geographically referenced data. They are the primary tools used to work with karttatietoaineisto, enabling users to visualize, query, and analyze spatial relationships and patterns. The development and maintenance of comprehensive and reliable karttatietoaineisto are ongoing processes that support informed decision-making and a deeper understanding of our spatial world.
