+# Dataset Card for SAVMAP (Enhanced Annotations)
+
+## Dataset Summary
+
+The SAVMAP dataset comprises ultrahigh-resolution aerial imagery captured by unmanned aerial vehicles (UAVs) over semi-arid savanna landscapes in Namibia. Originally released in 2015, the dataset includes raw JPEG images with embedded EXIF metadata (timestamp, latitude, longitude, altitude) and annotations identifying animals in the imagery.
+
+⚠️ **This version of the dataset includes improved annotations** to address issues found in the original Micromappers campaign, which was known to include many false positives. The updated annotations were curated and validated by **Paul Allin**, a PhD candidate at **Stellenbosch University (South Africa)**, providing a more accurate basis for training and evaluating computer vision models in ecological monitoring tasks.
+
+## Supported Tasks and Use Cases
+
+- **Object Detection**: Training and evaluation of animal detection models in ultrahigh-resolution aerial imagery.
+- **Remote Sensing for Ecology**: Analyzing habitat use and wildlife distributions in savanna environments.
+- **Biodiversity Conservation**: Informing sustainable land-use strategies and conservation interventions.
+
+## Languages
+
+Non-linguistic (imagery and geospatial data); metadata and documentation are provided in English.
+
+## Dataset Creation
+
+### Curation Rationale
+
+The original SAVMAP dataset was developed to demonstrate the use of UAV imaging for near real-time ecological monitoring and sustainable land-use planning. However, the reliance on crowdsourced annotations introduced quality issues. To make the dataset more useful for machine learning and conservation efforts, a new set of expert-curated annotations has been developed.
+
+### Source Data
+
+- **Imagery**: Captured in May 2014 over a Namibian savanna reserve using EPFL-designed UAVs.
+- **Expert Annotations**: Created by Paul Allin (Stellenbosch University), focusing on accuracy, removing false positives, and validating animal locations.
+
+## Annotation Process
+
+- **Enhanced (Paul Allin)**: Bounding boxes were created and reviewed manually by an ecologist with domain expertise, ensuring significantly improved data quality. The dataset has 379 positive samples (image with annotations) and 3545 negative samples (images without annotations).
+
+## Licensing Information
+
+The dataset is released under the **Academic Free License v3.0**. Please cite the original dataset creators and acknowledge the enhanced annotations as described below.
