Full Changelog: v0.7.0...v0.7.1

v0.7.0

This release contains several major updates of the code. These following updates might require small changes to your code:

• Most noticeable is the change in the hydromt build CLI, where made the region argument optional and deprecated the resolution option. Futhermore, the user has to force existing folders to be overwritten when building new models.
• We also did a major overhaul of the GeoDataset and the associated .vector assessor to support any type of vector geometries (before only points).

More new features, including support for rotated grids, new cloud data catalogs and (caching of) tiled raster datasets and more details are listed below.

Changed

• Removed resolution ('-r', '--res') from the hydromt build cli, made region (now '-r') an optional argument. PR #278
• If the model root already contains files when setting root, this will cause an error unless force overwrite (mode='w+' or --fo/--force-overwrite from command line). PR #278
• Revamped the GeoDataset (vector.py) to now work with geometry objects and wkt strings besides xy coordinates. PR #276
• GeoDataset can write to .nc that is compliant with ogr. PR #208
• Support for rotated grids in RasterDataset/Array, with new rotation and origin properties. PR #272
• Removed pygeos as an optional dependency, hydromt now relies entirely on shapely 2.0 PR #258
• Changed shapely to require version '2.0.0' or later. PR #228
• strict and consistent read/write mode policy PR #238
• do not automatically read hydromt_data.yml file in model root. PR #238
• RasterDataset zarr driver: possiblility to read from several zarr stores. The datasets are then merged and preprocess can
  be applied similar to netcdf driver. PR #249

Added

• New methods to compute PET in workflows.forcing.pet using Penman Monteith FAO-56 based on the pyet module. Available arguments are now method = ['debruin', 'makkink', 'penman-monteith_rh_simple', 'penman-monteith_tdew'] PR #266
• New get_region method in cli/api.py that returns a geojson representation of the parsed region. PR #209
• write raster (DataArray) to tiles in xyz stucture with the RasterDataArray.to_xyz_tiles method. PR #262
• add zoom_level to DataCatalog.get_rasterdataset method. PR #262
• new write_vrt function in gis_utils to write '.vrt' using GDAL. PR #262
• new predefined catalog for cmip6 data stored on Google Cloud Storage cmip6_data. Requires dependency gcsfs. PR #250
• new predefined catalog for public data stored on Amazon Web Services aws_data. Requires dependency s3fs. PR #250
• new DataCatalog preprocess function harmonise_dims for manipulation and harmonisation of array dimensions. PR #250
• experimental: support for remote data with a new yml data source filesystem attribute. Supported filesystems are [local, gcs, s3].
  Profile information can be passed in the data catalog kwargs under storage_options. PR #250
• experimental: new caching option for tiled rasterdatasets ('--cache' from command line). PR #286

Fixed

• bug related to opening named raster files. PR #262
• All CRS objects are from pyproj library (instead of rasterio.crs submodule). PR #230

Full Changelog: v0.6.0...v0.7.0

v0.6.0

v0.6.0 (24 October 2022)

In this release, we updated the Model API by renaming staticgeoms to geoms, adding a new maps object and removing abstract methods. We also added new general subclasses to Model: GridModel, LumpedModel, MeshModel, NetworkModel. These new subclasses have their own objects (e.g. grid for GridModel representing regular grids which replaces the old staticmaps object). More details in the list below:

Added

• ModelCatalog to discover generic and plugin model classes. PR #202 <https://github.com/Deltares/hydromt/pull/202>_
• Support for 2-dimensional tabular data through the new DataFrameAdapter. PR #153 <https://github.com/Deltares/hydromt/pull/153>_
• API calls to get info about model components and dataset for the dashboard. PR #118 <https://github.com/Deltares/hydromt/pull/118>_
• New submodelclasses in hydromt: GridModel, LumpedModel, MeshModel, NetworkModel
• Added entrypoints for lumped_model, mesh_model, grid_model
• New mixin classes created for model specific object: GridMixin for self.grid, LumpedMixin for self.response_units, MeshMixin for self.mesh,
  MapsMixin for self.maps
• New high-level object: self.maps for storing regular rasters data (which can have resolution and / or projection).
• Maps generic setup methods: MapsMixin.setup_maps_from_raster and MapsMixin.setup_maps_from_rastermapping
• Mesh generic setup methods: MeshModel.setup_mesh, MeshMixin.setup_maps_from_raster and MeshMixin.setup_maps_from_rastermapping

Changed

• self.staticgeoms object and methods renamed to self.geoms
• self.staticmaps object and methods renamed to self.grid and moved into GridModel and GridMixin

Fixed

• Bug in backward compatibility of staticgeoms (not read automatically). Issue #190 <https://github.com/Deltares/hydromt/issues/190>_
• Direct import of xarray.core.resample. Issue #189 <https://github.com/Deltares/hydromt/issues/189>_
• Bug in dim0 attribute of raster, removed instead of set to None if no dim0 Issue #210 <https://github.com/Deltares/hydromt/issues/210>

Deprecated

• self.staticgeoms and self.staticmaps are deprecated.

v0.5.0

v0.5.0 (4 August 2022)

We now use rioxarray to read raster data. We recommend reinstalling your hydromt environment including the rioxarray package.
Furthermore, we have changed some internals to support multiple predefined data catalogs and data archives. A detailed overview of all changes is shown below.

@IMarth and @xldeltares made their first contributions 🎉

Added

• New raster method for adding gdal_compliant() attributes to xarray object.
• Function to_datetimeindex in available preprocess functions for xr.open_dataset in the data adapter.
• Function remove_duplicates in available preprocess functions for xr.open_dataset in the data adapter.
• New DataCatalog.from_predefined_catalogs and DataCatalog.from_archive to support predefined data catalogs and archive
  in a generic way through the data/predefined_catalogs.yml file.
• Optional formatting for year and month variables in path of data sources.

Changed

• splitted data_adapter.py into a data_catalog and data_adapter submodule with py scripts per adapter
• Add rioxarray dependency to read raster data
• In build or update methods, the setup_config component is not forced to run first anymore but according to order of the components in the ini config (opt dict).
• In DataCatalog.get_RasterDataset & DataCatalog.get_GeoDataset methods, variables can now also be a str as well as a list of strings.
• In DataCatalog.get_RasterDataset & DataCatalog.get_GeoDataset methods, automatic renaming of single variable datasets based on the variables argument will be deprecated
• Interpolate missing values based on D4 neighbors of missing value cells only. This largely improves the performance without loosing accuracy.
  Changes have been observed when nearest method is used but this should not impact quality of the interpolation.
• New source_names argument to DataCatalog.to_yml

Fixed

• Fixed DataAdapter.resolve_paths with unknown keys #121
• Fixed the WGS84 datum in the gis_utils.utm_crs method.
• In merge.merge the grid is now aligned with input dataset with the largest overlap if no dst_bounds & dst_res are given.
• Fixed the predicate not being passed in get_geodataframe method.
• Removed deprecated xr.ufuncs calls.

Deprecated

• Automatic renaming of single var dataset if variables is provided in get_rasterdataset. Data catalog should be used instead.
• DataCatalog.from_artifacts. Use DataCatalog.from_predefined_catalogs instead.
