Description
A 5.5 KB Excel dataset by Zahra Omidighalehmohammadi, last updated in April 2026, details landscape metrics used to analyze urban heat islands in Tehran, Iran. The underlying study processed Landsat satellite data from 2015 to 2023 in Google Earth Engine, quantifying changes in green space connectivity and temperature zones. Results indicate a 1,400-hectare decrease in cold areas and a 1,618-hectare increase in hot zones over the study period.
Use Cases
Modeling connectivity flows between urban cool islands based on electrical circuit theory metrics.
Analyzing spatiotemporal fragmentation of green spaces based on landscape morphology metrics.
Identifying optimal NDVI thresholds for land classification based on ROC and TSS metrics.
Mapping resistance surfaces for ecological connectivity based on inverse NDVI data.
Strengths
Specific spatial and temporal coverage for Tehran, Iran from 2015 to 2023.
Results quantify changes with specific hectare measurements (e.g., 1,400 ha decrease in cold areas).

Limitations
Row count and column-level documentation are absent; field semantics must be inferred after download.
The dataset is very small (5.5 KB), indicating it likely contains summary metrics rather than raw observational data.
