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.

v0.4.5

Added

• New skill scores: KGE 2012, KGE non-parametric (2018), KGE non-parametric flood (2018).
• new rasterio inverse distance weighting method ("rio_idw") in raster.interpolate_na
• Add option to add placeholders in yml file to explode a single yml entry to multiple yml entries (useful for e.g. climate datasets).
• general Model.setup_region method

Changed

• stats.py is now in stats/skills.py in order to include more and different type of new statistics later.
• 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
• improved interbasin regions in workflows.get_basin_geometry
• drop non-serializable entries from yml file when writing data catalog to avoid it getting corrupt
• 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

Added

• flw.d8_from_dem to derive a flow direction raster from a DEM
• flw.reproject_hydrography_like to reproject flow direction raster data
• flw.floodplain_elevation method which returns floodplain classification and hydrologically adjusted elevation
• raster.flipud method to flip data along y-axis
• raster.area_grid to get the raster cell areas [m2]
• raster.density_grid to convert the values to [unit/m2]
• gis_utils.spread2d method (wrapping its pyflwdir equivalent) to spread values on a raster
• gis_utils.nearest and gis_utils.nearest_merge methods to merge GeoDataFrame based on proximity
• river_width to estimate a segment average river width based on a river mask raster
• river_depth to get segment average river depth estimates based bankfull discharge (requires pyflwdir v0.5.2)

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 writting files or costumizing 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

Fixed

• DataCatalog.to_yml Path objects written as normal strings
• 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

• flw.gaugemap is replaced by flw.gauge_map for a more conistent interace of flw.*map methods
• flw.basin_shape is redundant

v0.4.3

New

• log hydromt_data.yml with write_datata_catalog (needs to be implemented in various plugins)

Fixed

• Fix bug in io.open_vector and io.open_vector_from_table with WindowsPath fn
• Fix data_libs usage from [global] section of config in cli/main.py

Added

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

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
• read-only check in write_config; dropped write_results
• results objects of Model API can also contain xarray.Dataset. To split a Dataset into DataArrays use the split_dataset option of set_results.

Deprecated

• Importing model plugins via "hydromt import xxxModel" or "import hydromt.xxxModel" will be deprecated. Instead use "from hydromt.models import xxxModel"
  or "from hydromt_xxx import xxxModel".

Fixed
