# Northern Evia Fire Recovery — Sentinel-2 Change Detection

## Question

How did satellite-observed vegetation condition change after the 2021 northern
Evia wildfire, and how spatially uniform was the subsequent recovery?

## Event and study area

[Document EMSR527, AOI01, product version, delivery date and the exact filtered
feature used as the fire perimeter.]

## Data

[Record the Earth Engine collection, dates, bands, scale factors, licences and
retrieval date.]

## Method

[Summarise masking, compositing, analysis grid, indices, recovery denominator,
strata, summary statistics, exports and checks.]

## Main findings

[Populate only after executing and reviewing the analysis. Do not invent
quantitative results.]

## Limitations

[State what the spectral analysis can and cannot establish.]

## Reproduce

[Link the Earth Engine script, uploaded perimeter asset, manifest and outputs.]

## Skills demonstrated

Sentinel-2 surface reflectance; Google Earth Engine; cloud/shadow QA; NBR;
dNBR; NDVI; multi-year change detection; spatial stratification; uncertainty;
reproducible environmental communication.
