Service Description: This service provides georeferenced high-resolution KH-9 HEXAGON satellite imagery acquired in 1975 and covering the High Tatras region of Slovakia and Poland. The original declassified satellite imagery was obtained from the U.S. Geological Survey (USGS), Earth Resources Observation and Science (EROS) Center. The imagery was georeferenced and processed by the Technical University in Zvolen within the RETROCHANGE project.
The service is dynamically rendered and is intended for flexible visualization, analysis, and use in GIS clients where dynamic map generation or reprojection is required.
The dataset is intended for retrospective analysis of forest and landscape change, historical land-cover mapping, forest monitoring, forest fragmentation and edge analysis, landscape structure assessment, and comparison with contemporary geospatial datasets.
Positional accuracy may vary spatially due to the characteristics of historical satellite imagery and the georeferencing process. The dataset is not intended for cadastral, legal, engineering, or survey-grade applications.
Alternative cached services are available in EPSG:5514 and EPSG:3857.
