Core Features

  • Collections & Indexing

    • Define a geographic area and date range to create a custom collection.

    • Ready-to-use collections of open imagery.

  • Similarity Search

    Find visually or semantically similar locations across satellite imagery with geo-embeddings.

    • Search by chip ID to find visually similar tiles.
    • Use text descriptions to find features by concept (e.g. "solar farm").
    • Constrain results spatially with a GeoJSON polygon and configure top_k.

  • Change Detection

    Compare historical and current imagery to detect semantic or visual change in any region.

    • Detect change using text descriptions or chip-based visuals.
    • Combine positive and negative examples to tune detection.
    • Results scored and ranked by degree of change.
