HOW TO MAKE A MAP LIKE THIS ONE USING ARCMAP, QGIS & A LITTLE BIT OF EXCEL:

1. Follow this amazing tutorial until you reach 15:29: https://www.youtube.com/watch?si=o3KlbA0VqjK5Rd-K&v=D_uYjqZ1nYw&feature=youtu.be

2. Export your map to a folder you will be able to locate. It will be exported as a raster layer.

3. Download the SRTM DEM data for your region of interest from https://earthexplorer.usgs.gov/. In QGIS, add the data as a raster layer.

4. Open QGIS and add the raster layer you exported in step 2.

5. Name this raster layer & gight-click on it and select "Properties". Rename the LULC classes following the order with which they are named in ArcMap. And give the respective classes their suitable colors.

6. Right-click on this layer again and open the Raster Attribute Table.

7. Copy the data in the Raster Attribute Table to Excel and make a bar and a pie chart. Match the bar and pie chart colors from the colors you created in step 5.

8. Right-click on each chart and select "Save as Picture" to a folder which you will be able to locate.

9. Back in QGIS, Add all other vector layers you might want to add, like the layers of provinces, districts, etc. This step is optional.

10. Click on the "Processing Toolbox" and search for "Hillshade". Select the "Hillshade" under "GDAL".

11. For the Input layer, select the DEM data layer which you added in step 3, and then click on " Run".

12. Right-click on the Hillshade layer and select " Properties". On "Color gradient" under "Band Rendering", select "Black to White".

13. On " Blending mode" under "Layer Rendering", select "Multiply".

14. On " Brightness" under "Layer Rendering", give a value of 100 or 110. Click "Apply" and then "OK".

15. Click on "Project" on the top-left corner and select "New Print Layout". Give this layout your preferred name.

16. Add a "Fixed table", and copy all the values from the data you entered in Excel in step 7, making it look like the one shown in the attached map.

17. Add your

Understanding Spatial Resolutions: ASTER, Landsat, Sentinel & UAVs

In Remote Sensing, spatial resolution refers to the smallest object that a sensor can detect. Choosing the right dataset often depends on the balance between resolution, cost, and coverage. Here's a quick comparison:

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)

Sentinel-2

➡️ Multispectral: 10 m, 20 m, 60 m (depending on the band)

UAVs (Drones)

➡️ Extremely high resolution: \~2–20 cm, depending on flight altitude and sensor.

🎯 Key takeaway:

👉🏼 Use ASTER and Landsat for regional studies (e.g., land cover, geology).

👉🏼 Sentinel-2 is ideal for medium-scale environmental monitoring with frequent revisit times.

👉🏼 UAVs offer ultra-high detail for site-specific studies like precision agriculture, infrastructure inspection, or conservation mapping.

🛰️ From meters to centimeters, the choice of spatial resolution can make or break your analysis.

💬 Which of these platforms do you use most often in your work?
