Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

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

v0.2.6 - 2019-08-28

Added

  • Support for in operator on property fields
  • 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.

Added

  • New ids parameter added for searching by IDs
  • New collections parameter added for searching list of specific collections

Changed

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

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.

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

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

v0.2.2 - 2019-01-21

Fixed

  • Fix error handling of single Items written to Elasticsearch.

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.

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

v0.1.0 - 2018-09-18

Fixed

  • Fixed broken ingests for Landsat and Sentinel

v0.0.2

Added

  • Added support for STAC specification
  • The following packages are released
    • @sat-utils/api
    • @sat-utils/api-lib
    • @sat-utils/ingest
    • @sat-utils/landsat
    • @sat-utils/sentinel
    • @sat-utils/manager
  • A new document is added on how to configure and deploy and instance of sat-api

Changed

  • All lambdas and packages moved to /packages and lerna is used for managing them
  • npm packages are published under @sat-utils org on npm

Removed

  • /geojson endpoint
  • /count endpoint

legacy-v2.0.0 - 2018-01-01

  • Moves all the metadata indexing logics to the same repo
  • Uses CloudFormation for full deployment
  • Includes a better ApiGateway support
  • Use streams to read, transform, and write into elasticsearch
  • Use batches of lambdas to speed up processing
  • Refactor several modules: metadata, landsat, sentinel
  • Refactor and improve splitting
