SAS Planet and Satellite Image Resolution:
SAS Planet: This free and open-source software allows you to view and download satellite imagery from various sources. It's a popular tool for geographers, researchers, and anyone interested in exploring the world from above.
Satellite Image Resolution: This refers to the level of detail captured in the image. Higher resolution images show more detail, allowing you to zoom in and see individual objects like buildings, cars, or even people. Lower resolution images are better for larger-scale views.
Understanding Resolution in SAS Planet:
Available Sources: SAS Planet integrates with various satellite imagery providers, each offering different resolutions. Some well-known sources include:
World Imagery: Generally lower resolution (around 15-30 meters), good for regional overviews.
DigitalGlobe: Offers various resolutions, including high-resolution options of 0.3-0.5 meters, allowing you to see incredible detail.
Sentinel-2: Offers medium resolution (10 meters), useful for land cover analysis and environmental monitoring.
Viewing Resolution: Within SAS Planet, you can check the resolution of the current image by looking at the information bar at the bottom of the window. It's usually displayed in meters per pixel (m/px).
Zooming: You can zoom in and out of the image using the zoom controls or your mouse wheel. However, zoom beyond the native resolution won't reveal additional detail; the image will just become pixelated.
Tips for Exploring High-Resolution Imagery:
Explore different providers: Check the available options in SAS Planet and their resolution capabilities.
Focus on areas of interest: Don't download entire high-resolution images unless necessary. Instead, focus on specific areas you want to explore in detail.
Be aware of data costs: Downloading high-resolution imagery can use significant data depending on the provider and coverage area.
Check image dates: Remember that satellite images might not be the latest representation of an area.
