Terrain Tiles gridded elevation tiles data library

Hosted on AWS S3 https://registry.opendata.aws/terrain-tiles/

Description: Gridded elevation tiles
Resource type: S3 Bucket
Amazon Resource Name (ARN): arn:aws:s3:::elevation-tiles-prod
AWS Region: us-east-1

Documentation: https://mapzen.com/documentation/terrain-tiles/

Parameters:

zoom (int) – Zoom level of tiles. Defaults to 6.
tile_format (str) – One of [‘geotiff’, ‘terrarium’, ‘normal’]. Defaults to ‘geotiff’ PODPAC node can only evaluate ‘geotiff’ formats. Other tile_formats can be specified for download() No support for ‘skadi’ formats at this time.
bucket (str) – Bucket of the terrain tiles. Defaults to ‘elevation-tiles-prod’

Alternative Constructors

`from_definition`(definition)	Create podpac Node from a dictionary definition.
`from_json`(s)	Create podpac Node from a JSON definition.

Methods

`__init__`(**kwargs)	Do not overwrite me
`composite`(coordinates, data_arrays[, result])	Composites data_arrays (tiles) into a single result.
`create_output_array`(coords[, data, attrs, ...])	Initialize an output data array
`download`([path])	Download active terrain tile source files to local directory
`eval`(coordinates, **kwargs)	Wraps the super Node.eval method in order to cache with the correct coordinates.
`eval_group`(group)	Evaluate the node for each of the coordinates in the group.
`find_coordinates`()
`from_name_params`(name[, params])	Create podpac Node from a WMS/WCS request.
`from_url`(url)	Create podpac Node from a WMS/WCS request.
`get_bounds`([crs])	Get the full available coordinate bounds for the Node.
`get_cache`(key[, coordinates])	Get cached data for this node.
`get_source_data`([bounds])	Get composited source data, without interpolation.
`get_ui_spec`([help_as_html])	Get spec of node attributes for building a ui
`has_cache`(key[, coordinates])	Check for cached data for this node.
`init`()	Overwrite this method if a node needs to do any additional initialization after the standard initialization.
`iteroutputs`(coordinates[, _selector])	Summary
`load`(path)	Create podpac Node from file.
`probe`([lat, lon, time, alt, crs])	Evaluates every part of a node / pipeline at a point and records which nodes are actively being used.
`put_cache`(data, key[, coordinates, expires, ...])	Cache data for this node.
`rem_cache`(key[, coordinates, mode])	Clear cached data for this node.
`save`(path)	Write node to file.
`select_sources`(coordinates[, _selector])
`trait_defaults`(names, *metadata)	Return a trait's default value or a dictionary of them
`trait_has_value`(name)	Returns True if the specified trait has a value.
`trait_is_defined`(name)
`trait_values`(**metadata)	A `dict` of trait names and their values.
