Vector

Warning

This low-level client has been replaced with the object-oriented Tables client.


class Vector(url=None, auth=None)[source]

Client for storing and querying vector data.

The Descartes Labs Vector service allows you store vector features (points, polygons, etc.) with associated key-value properties, and query that data by geometry or by properties.

It works best at the scale of millions of features. For small amounts of vector data that easily fit in memory, working directly with a GeoJSON file or similar may be more efficient.

Concepts:

  • “Feature”: a single geometric entity and its associated metadata (equivalent to a GeoJSON Feature).

  • “Product”: a collection of related Features, with a common id, description, and access controls.

This client currently returns data as dictionaries in JSON API format.

Parameters

  • url (str) – A HTTP URL pointing to a version of the storage service (defaults to current version)

  • auth (Auth) – A custom user authentication (defaults to the user authenticated locally by token information on disk or by environment variables)

  • retries (urllib3.util.retry.Retry) – A custom retry configuration used for all API requests (defaults to a reasonable amount of retries)

  • readers (list(str)) – User, group, or organization IDs that can read this product. Each ID must be prefixed with user:, group:, or org:.

  • writers (list(str)) – User, group, or organization IDs that can edit this product. Each ID must be prefixed with user:, group:, or org:.

  • name (str) – (Deprecated) Will be removed completely in future versions.

Return type

DotDict

Returns

Replaced vector product, as a JSON API resource object. For a description of the keys, please see get_product().

Raises

  • BadRequestError – Raised when the request is malformed, e.g. the owners list is missing prefixes.

  • NotFoundError – Raised if the product cannot be found.

  • RateLimitError – Raised when too many requests have been made within a given time period.

  • ServerError – Raised when a unknown error occurred on the server.

search_features(product_id, geometry=None, query_expr=None, query_limit=None, **kwargs)[source]

Iterate over vector features within an existing product.

At least one of geometry, query_expr, or query_limit is required.

The returned iterator has a length that indicates the size of the query.

Parameters

  • product_id (str) – (Required) The ID of the product within which to search.

  • geometry (dict) –

    Search for Features intersecting this shape. This accepts the following types of GeoJSON or Shapely geometries:

    • Points

    • MultiPoints

    • Polygons

    • MultiPolygons

    • LineStrings

    • MultiLineStrings

    • GeometryCollections

  • query_expr (Expression) – Expression used to filter features by their properties, built from dl.properties. You can construct filter expression using the ==, !=, <, >, <= and >= operators as well as the like() and in_() methods. You cannot use the boolean keywords and and or because of Python language limitations; instead you can combine filter expressions with & (boolean “and”) and | (boolean “or”). Example (assuming from descarteslabs import properties as p): query_expr=(p.temperature >= 50) & (p.hour_of_day > 18). More complex example: query_expr=(100 > p.temperature >= 50) | ((p.month != 10) & (p.day_of_month > 14)). If you supply a property which doesn’t exist as part of the expression that comparison will evaluate to False.

  • query_limit (int) – Maximum number of features to return for this query, defaults to all.

Return type

Iterator of DotDict instances

Returns

Features satisfying the query, as JSONAPI primary data objects. For a description of the keys, please refer to create_feature() under the data key.

len() can be used on the returned iterator to determine the query size.

Raises

  • BadRequestError – Raised when the request is malformed, e.g. the query limit is not a number.

  • NotFoundError – Raised if the product cannot be found.

  • RateLimitError – Raised when too many requests have been made within a given time period.

  • ServerError – Raised when a unknown error occurred on the server.

update_product(product_id, name=None, title=None, description=None, owners=None, readers=None, writers=None)[source]

upload_features(file_ish, product_id, max_errors=0, fix_geometry='accept')[source]

Asynchonously upload a file or stream of Newline Delimited JSON features. Note that the file may not contain empty lines or lines containing anything but the feature (including e.g. a trailing comma), or such lines will cause errors.

It is recommended that the IOBase object is a byte-oriented (not text-oriented) object, although Python 3 allows io.StringIO to be used.

This is an asynchronous operation and you can query for the status using get_upload_result() with the upload_id returned by this method.

Parameters

  • file_ish (str or io.IOBase) – an open io.IOBase object, or a path to the file to upload.

  • product_id (str) – (Required) The ID of the Vector product to which these features will belong.

  • max_errors (int) – The maximum number of errors permitted before declaring failure.

  • fix_geometry (str) – String specifying how to handle certain problem geometries, including those which do not follow counter-clockwise winding order (which is required by the GeoJSON spec but not many popular tools). Allowed values are reject (reject invalid geometries with an error), fix (correct invalid geometries if possible and use this corrected value when creating the feature), and accept (the default) which will correct the geometry for internal use but retain the original geometry in the results.

Return type

str

Returns

The upload id.

Raises

  • NotFoundError – Raised if the product cannot be found.

  • RateLimitError – Raised when too many requests have been made within a given time period.

  • ServerError – Raised when a unknown error occurred on the server.
