Скачать или смотреть Event Based Fire Hotspot Analysis and Mapping using NASA FIRMS Data and ArcGIS

1. Download Fire Hotspot Data
Select appropriate sensor (MODIS or VIIRS). Website Link- https://firms.modaps.eosdis.nasa.gov/
Video Link-   • Process to download data from FIRMS for Fi...  
Choose area of interest and time period.
Download data in shapefile format.

2. Import Data into GIS
Add the downloaded shapefile into ArcGIS.
Export a working copy if necessary.
Project the data into an appropriate coordinate system (e.g., UTM Zone suitable for Nepal).

3. Integrate Nearby Fire Points
Use an integration tool to merge fire points within a selected threshold distance (e.g., 500 m or 1 km).
This removes duplicate or very close detections.

4. Collect Events
Use the “Collect Events” tool.
Generate a new dataset containing incident counts (ICOUNT field).
This represents fire frequency per location.

5. Test for Spatial Clustering
Perform Spatial Autocorrelation (Moran’s I).
Use the incident count (ICOUNT) field.
Determine whether fire occurrences are clustered, dispersed, or random.
Proceed only if clustering is statistically significant.

6. Perform Hotspot Analysis
Use Getis-Ord Gi* Hotspot Analysis.
Select the incident count field.
Apply an appropriate distance band.
Identify statistically significant hotspots and cold spots.

7. Interpolate Hotspot Surface
Use IDW interpolation.
Select the GiZScore field as input.
Generate a continuous raster surface representing hotspot intensity.

8. Reclassify the Interpolated Raster
Classify raster values into categories (e.g., low, moderate, high hotspot).
Use appropriate threshold ranges.

9. Prepare Final Map Layout
Add title, legend, scale bar, north arrow.
Include projection information.
Mention data source.
Export final hotspot map.
