0.3.0

[v0.3.0] - 2019-10-16

Added

• /stac/search linked to from /stac
• New ids parameter added for searching by IDs
• New collections parameter added for searching list of specific collections
• SATAPI_COLLECTION_LIMIT environment variable added for the number of collections to return at the /stac and /collections endpoints. Since pagination is not supported at these endpoints this should be set higher than the number of collections available. Defaults to 100.

Changed

• Fields parameter changed to search on any fields rather than just fields under properties. Field under properties must now be referenced by properties.<fieldname>
• collection now a top level field rather than a property

0.2.6

[v0.2.6] - 2019-08-28

Added

• Support for in operator on property fields

0.2.5

[v0.2.5] - 2019-06-21

Fixed

• Added missing dependency (through2)

Removed

• Removed gzip compression which caused problems with APIGateway. Use APIGateway to enable compression instead rather than in the library.

0.2.4

[v0.2.4] - 2019-06-02

Added

• Add fields filter to return only specific fields
• Added SATAPI_URL environment variable for defining a custom root URL used for creating hierarchical links. Otherwise, the root URL will try to be inferred from the headers.
• Gzip compression added for clients that support it (via Accept-Encoding)
• Added SATAPI_ES_PRECISION environment variable to change the precision for underlying intersection geometry queries. This will have an adverse impact on performance and storage size. If changed after ingestion, a reindex operation will need to be performed. It defaults to '5mi' (5 miles).

Fixed

• Fix datetime range to be inclusive (i.e., gte and lte)
• Fixed next links to properly stringify geometries

0.2.3

[v0.2.3] - 2019-01-29

Fixed

• Proper handling of bounding box passed as string

Changed

• De-normalize Item properties to include all properties from collection
• Flattened elastic search to simplify query logic
• Items returned will now include all 'Common' properties that are in the Items Collection

0.2.2

[v0.2.2] - 2019-01-21

Fixed

• Fix error handling of single Items written to Elasticsearch.

0.2.1

[v0.2.1] - 2019-01-17

Fixed

• Error handling of Items failing to get written to Elasticsearch (such as when unable to parse geometry). Now will continue traversing catalog.

0.2.0

[v0.2.0] - 2019-01-16

Changed

• Implemented the changes in STAC 0.6.0
• All functionality relating to handling a STAC API path and query parameters has been moved into a the api.js module. The simplified lambda handler now passes query parameters or POST body through to the api.js module.
• API now only supports STAC compliant query parameters and filters.
• All functionality and references relating to Elasticsearch have been migrated into the es.js module to faciltate separation of concerns and abstract data storage.
• Refactored Elasticsearch queries and ES mappings to search and share fields with the properties nested type. Now, only fields under a Collections properties are inherited by the Item.
• Elasticsearch queries have been updated to use non-scoring filters to improve performance and return more intuitive results.
• Elasticsearch writing has been modified to use bulk updates whenever possible to improve throughput.
• Ingest has been updated to use concurrent file requests (to a user defined limit) to improve throughput.
• Ingest now supports a Fargate mode to run as a Fargate task rather than as a Lambda.
• API documentation generation now uses OpenAPI definitions processed by widdershins and shins.
• Unit and integration test coverage for all modules.

Removed

• Manager module: Removed in favor of Kibana for Elasticsearch administration and management tasks.
• Landsat and Sentinel lambda functions: Data is now ingested via the ingest Lambda. It can be invoked with individual SNS messages or run in batch mode to ingest larger catalogs.
• Deployment files: Deployment related templates and code have been migrated to https://github.com/sat-utils/sat-api-deployment
