Observation Instance – Django REST framework

Get a list of Observation objects.

### Available end points:

- `/observations/` - Will list all Results in the database
- `/observations.json` - Will return all Results in json format. This can
also be achieved by using the accept header. `application/json`
- `/observations/<object_id>/` - Returns Results object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

- `title`
- `uuid`
- `keywords`
- `status`
- `result_field`
- `discoveryKeywords`
- `updateFrequency`
- `nonGeographicFlag`
- `publicationState`
- `permissions`

### How to use filters:

These filters can be used like django query filters using __ for related model relationships.

- `/observations/?uuid=d594d53df2612bbd89c2e0e770b5c1a0`
- `/observations/?status=completed`
- `/observations/?results_field__dataPath__startswith=/neodc/esacci`
- `/observations/?discoveryKeywords__name=ESACCI`
- `/observations/?nonGeographicFlag=True`

Filters can be stacked to build an 'AND' relationship. E.g.

- `/observations/?publicationState__in=published,citable&nonGeographicFlag=True`
- `/observations/?publicationState__in=published,citable&discoveryKeyword__name=NDGO0003`

This product is a Beta version and should be used for testing purposes only.\r\n\r\nThe BETA MERGED Fire_cci Burned Area (BA) product v0.1 (also called FireCCIM01 for short) was obtained using machine learning techniques to obtain a FireCCI51-like (https://catalogue.ceda.ac.uk/uuid/3628cb2fdba443588155e15dee8e5352) burned area product based on the FireCCILT11 (https://catalogue.ceda.ac.uk/uuid/62866635ab074e07b93f17fbf87a2c1a) grid product.\r\n\r\nIt is available for the years 1982 to 2018 (with a gap in 1994 due to lack of FireCCILT11 information) in grid (0.25 degrees) format.\r\n\r\nThe files in these directories include Burned area information with 2 layers: Sum of burned area and Uncertainty (as obtained from the Deep Neural Network results).  A global coverage of 0.25 x 0.25 degrees grid resolution is stored in a single file for each monthly period.",
