Habitually referred to as old satellite maps, historical imagery from satellites ( satellite images ) is one of the most significant factors that influence the way GIS operates today. In addition to supplying real-time geographic data, through analysis of the past Earth's conditions, we can make long-term plans, monitor our environment, and manage spatial decisions. This article provides an overview of historical imagery from satellites, its sources, and how it continues to serve a major...

Sentinel-2 is one of the most widely used Earth observation missions for GIS, remote sensing, and environmental monitoring. Operated by the European Space Agency (ESA) under the Copernicus Programme, Sentinel-2 provides high-resolution, multispectral imagery that is freely available and ideal for land, vegetation, water, and urban analysis. Sentinel-2 Bands for GIS and Earth Observation What Is Sentinel-2? Sentinel-2 consists of two satellites (Sentinel-2A and Sentinel-2B) flying in the same...

The Dead Sea coordinate map is a critical geospatial resource for professionals working in GIS, remote sensing, surveying, environmental science, and spatial analysis. Located at the lowest exposed elevation on Earth, the Dead Sea presents unique cartographic and geodetic challenges that require precise coordinate systems, accurate projections, and consistent spatial referencing. This technical guide explores how Dead Sea coordinate maps are used in GIS and geospatial applications, covering...
