  • ModelCatalog to discover generic and plugin model classes. PR #202

  • Support for 2-dimensional tabular data through the new DataFrameAdapter. PR #153

  • API calls to get info about model components and dataset for the dashboard. PR #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

  • Direct import of xarray.core.resample. Issue #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 (4 August 2022)#

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.

  • 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.

  • improved flw.reproject_hydrography_like and flw.dem_adjust methods

  • file handlers of loggers are replaced in Model.set_root

  • log.setuplog replaces old handlers if these exist to avoid duplicates.

  • setup_basemaps method no longer required for build method

  • data catalog yml entries get priority over local files or folders with the same name in the data_adapter.get_* methods multi-file rasterdatasets are only supported through the data catalog yml file

Fixed#

  • fix incorrect nodata values at valid cells from scipy.griddata method in raster.interpolate_na

Deprecated#

  • workflows.basemaps methods (hydrography and topography) moved to hydromt_wflow

v0.4.4 (19 November 2021)#

Added#

  • flw.d8_from_dem to derive a flow direction raster from a DEM

Changed#

  • bumped hydromt-artifacts version to v0.0.6

  • In model API build and update functions, if any write* are called in the ini file (opt), the final self.write() call is skipped. This enables passing custom arguments to the write* functions without double writing files or customizing the order in which write* functions are called. If any write* function is called we assume the user manages the writing and a the global write method is skipped.

  • default GTiff lwz compression with DataCatalog.export_data method

  • rename DataAdapter.export_data to DataAdapter.to_file to avoid confusion with DataCatalog.export_data method

  • allow “alias” with attributes in DataCatalog yml files / dictionaries

  • Bugfix in basin_mask.get_basin_geometry when using bbox or geom arguments

  • Bugfix DataAdapter.__init__ setting None value in meta data

  • Bugfix DataAdapter.resolve_paths with argument in root

Deprecated#

Added#

  • Small patch for geoms/bbox regions when upscaling flow dir.

  • Mask option in merge.merge method for improved open_raster_from_tindex.

Changed#

  • New import of model plugins. Before plugins were only loaded when import MODELS or xxxModel from hydromt.models and not when importing hydromt as before.

  • Dropped dask version pins

v0.4.0 (23 April 2021)#

This is the first stable release of hydroMT. Noticeable changes are the addition of the deltares-data flag, improvements with basin masking functionnalities, and the creation of examples notebooks available in the documentation and in Binder.

Added#

  • Support the use of data stored at Deltares by introducing the ==deltares-data flag to the CLI and according property to the DataCatalog and Model API.

  • Added outlet_map and stream_map functions in flw.py.

  • Added mask function to raster.py for RasterDataArray and RasterDataset class.

  • Binder environment to run examples notebooks.

Changed#
