1. Spatial Resolutions: ASTER, Landsat, Sentinel & UAVs

In EO, spatial resolution determines the size of the smallest object that can be detected by a sensor. Choosing the right dataset often depends on the balance between resolution, cost & coverage. Here's a quick comparison: 2. ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer)

➡️ VNIR: 15 m
➡️ SWIR: 30 m
➡️ TIR: 90 m

Landsat (e.g., Landsat 8/9)

➡️ Multispectral: 30 m
➡️ Panchromatic: 15 m
➡️ Thermal: 100 m (resampled to 30 m)

HOW TO MAKE A MAP LIKE THIS ONE IN QGIS:

1. Download the SRTM 1 Arc-Second Global data for your region of interest from the USGS Earth Explorer website ().

2. Build a virtual raster in QGIS if you have several tiles. lnkd.in/dhfrySmj 3. Clip the virtual raster by your region's boundary. At this point, we have a basic elevation map.

4. Style your elevation map in symbology to show the different elevation ranges.
