v0.3.0

Release Notes

Changed

• Refactor the package to run in Jupyter notebooks without using nest-asyncio. This is
  done by creating and initializing a single global event loop thread dedicated to
  only running the asynchronous parts of this package. As a result, nest-asyncio is
  no longer needed as a dependency.
• Remove the out_crs option from get_map since the 3DEP service returns inconsistent
  results when the output CRS is not its default value of 3857. This is a breaking
  change since this value cannot be configured and the default value has changed from
  5070 to 3857.

v0.2.3

Release Notes

Changed

• Use aiohttp and aiofiles for more performant and robust handling of service calls
  and downloading of 3DEP map requests. This should limits the number of connections
  made to the dynamic 3DEP service to avoid hammering the service and can reduce the
  memory usage when downloading large files. As a results, aiohttp and aiofiles
  are now required dependencies and urllib3 is no longer needed.
• More robust handling of closing VRTPool at exit by creating a new class method
  called close. This method is called by the atexit module to ensure that the
  pools are closed when the program exits.

v0.2.2

Release Notes

Changed

• Considerable improvements in making service calls by creating connection pools using
  urllib3.HTTPSConnectionPool and rasterio.open. This should improve performance
  and robustness of service calls, and reduce the number of connections made to both
  the static and dynamic 3DEP services. As a results, urllib3 is now a required
  dependency.
• Add a new private module called _pools that contains the connection pools for making
  service calls. The pools are lazily initialized and are shared across threads.
  Especially the VRT pools are created only when a specific resolution is requested,
  and are reused for subsequent requests of the same resolution. As such, the VRT info
  are loaded only once per resolution without using lru_cache.

v0.2.1

Release Notes

Changed

• Improve downloading of 3DEP map requests in get_map by streaming the response
  content to a file instead of loading it into memory. Also make exception handling
  more robust. The function has been refactored for better readability and
  maintainability.
• Change the dependency of build_vrt from gdal to libgdal-core as it is more
  lightweight and does not require the full gdal package to be installed.
• Improve documentation.

v0.2.0

Release Notes

Changed

• Since 3DEP web service returns incorrect results when out_crs is 4326,
  get_map will not accept 4326 for the time being and the default value
  is set to 5070. This is a breaking change.
• Improve exception handling when using ThreadPoolExecutor to ensure that
  exceptions are raised in the main thread.
