 ### Technical Notes:
-* **Modifiable Parameters:** Models marked with **5** parameters support advanced dynamic environmental and reflected temperature adjustments. Models marked with **4** follow the standard DJI thermal metadata schema.
-* **EXIF Compatibility:** Models marked with ❌ store thermal data in encrypted proprietary structures that are not accessible via standard EXIF/XMP parsers; these require specific decryption/mapping via DJI's native libraries.
+* **Modifiable Parameters:** The standard 4 parameters are:
+  - `Object Distance`
+  - `Emissivity`
+  - `Relative Humidity`
+  - `Reflected Temperature`
+  
+  Newer models (H30T/M4T) support a 5th parameter:
+  - `Ambient Temperature`
+  
+* **EXIF Compatibility:** Models marked with ❌ store thermal data in encrypted proprietary structures; these require specific decryption/mapping via DJI's native libraries.
 * **Metadata Versioning:** All dataset metadata and telemetry extraction was performed using **ExifTool version 13.59**.

 ## 🚀 Use Cases
-* **Metadata Parsing:** Validate your software's ability to extract EXIF/XMP tags such as Emissivity, Relative Humidity, Target Distance, and Background Temperature specific to DJI's format.
-* **Radiometric Conversion:** Benchmark your algorithms that convert raw Digital Numbers (DN) into accurate Celsius/Fahrenheit temperature readings using DJI's thermal SDKs or custom formulas.
+* **Metadata Parsing:** Validate your software's ability to extract EXIF/XMP tags or handle SDK-based decryption.
+* **Radiometric Conversion:** Benchmark your algorithms that convert raw Digital Numbers (DN) into accurate temperature readings.
 * **Software QA:** Run automated stress tests for drone mapping and inspection applications.
 
-> 🔒 **Privacy & Data Protection Note:** All GPS coordinates, altitude data, and location-specific metadata have been intentionally stripped or disabled from the images in this dataset. This measure ensures the absolute privacy and security of the geographic locations where the data was captured, without affecting the core radiometric telemetry required for thermal calibration.

 ## 📁 Dataset Structure
-The dataset is organized by camera model. Inside each folder, you will find raw images formatted exactly as they come out of the drone's SD card (e.g., `DJI_M3T.JPG`, `DJI_H30T_T.JPG`, `DJI_M4T_R.JPG`).
-The EXIF metadata extraction is attached as .json
-The DJI Thermal SDK metadata is attached as .json
