📉Query Ellipsis Drive layers from your application

Ellipsis Drive provides query capabilities that allow you to interact with raster and vector layers directly from your application, alongside the visualization capabilities.

These capabilities enable data retrieval, insights generation, and support dynamic visualisation without exporting datasets.

Raster queries

Common raster query operations include:

• Get statistics within a polygon

• Retrieve raster values at one or more points

• Create a visualization by combining multiple raster layers

• Apply dynamic styling using a custom style object instead of a predefined style ID

Custom style objects allow runtime control over how raster data is visualised.

Vector queries

Common vector query operations include:

• Retrieve features at a specific location

• Find recently updated features

• Edit existing features

• Query features by spatial extent (bounding box)

• Query features by feature ID

• Apply dynamic styling using a custom style object instead of a predefined style ID

These operations support both data retrieval and direct feature manipulation.
