Question 1

What satellite data does GeoVerdant use?

Accepted Answer

We primarily utilize NASA's Harmonized Landsat Sentinel-2 (HLS) dataset, which provides high spatial resolution (30m) surface reflectance imagery. This combined dataset ensures a high revisit frequency, allowing you to monitor changes more consistently.

Question 2

Do you automatically handle clouds and shadows?

Accepted Answer

Yes, our processing pipeline automatically applies cloud and cloud-shadow masks using the Fmask algorithm provided within the HLS QA layers, ensuring your vegetation indices are computed only on clear pixels.

Question 3

How long does it take to process an Area of Interest (AOI)?

Accepted Answer

Processing times vary based on the size of the AOI, the selected date range, and the number of indices requested. However, our distributed architecture dynamically scales to handle large requests, splitting them into manageable sub-jobs for faster turnaround.

Question 4

Can I export my data for offline use?

Accepted Answer

Absolutely. You can export time-series data as CSV files for further statistical analysis or reporting in your own tools.

Question 5

What is the maximum AOI size I can process at once?

Accepted Answer

Currently, you can define an AOI of up to 500 km². For areas larger than this, we recommend breaking your request into multiple smaller regions to ensure the system processes them efficiently.

Question 6

What indices are supported out-of-the-box?

Accepted Answer

We support NDVI (Normalized Difference Vegetation Index), EVI (Enhanced Vegetation Index), NDWI (Normalized Difference Water Index), SAVI (Soil Adjusted Vegetation Index), NDRE (Normalized Difference Red Edge), and LAI (Leaf Area Index).
