Kaukokartoitusaineistojen (remote sensing data) are information collected from a distance, typically from aircraft or satellites. This data is used to monitor and analyze various environmental and geographical features. The primary sources of remote sensing data include optical sensors, which capture visible and near-infrared light, and radar sensors, which use microwaves to penetrate clouds and darkness. Optical sensors provide detailed images of the Earth's surface, useful for applications like land use mapping and vegetation monitoring. Radar sensors, on the other hand, offer data on surface structure and moisture content, valuable for flood mapping and soil analysis. Remote sensing data is processed and analyzed using specialized software to create maps, models, and other geospatial products. These products are essential for urban planning, disaster management, and environmental conservation efforts. The data can be collected at different resolutions, from high-resolution images for detailed analysis to low-resolution images for broader coverage. The frequency of data collection can vary, with some sensors providing daily updates and others offering less frequent but more detailed information. Remote sensing data is a critical tool in modern geography and environmental science, enabling researchers and practitioners to study and manage the Earth's resources effectively.
