pyramids - GIS utility package

pyramids is a GIS utility package using gdal, ....

pyramids

Main Features

• GIS modules to enable the modeler to fully prepare the meteorological inputs and do all the preprocessing needed to build the model (align rasters with the DEM), in addition to various methods to manipulate and convert different forms of distributed data (rasters, NetCDF, shapefiles)

Future work

• Developing a DEM processing module for generating the river network at different DEM spatial resolutions.

Installing pyramids

Installing pyramids from the conda-forge channel can be achieved by:

conda install -c conda-forge pyramids=0.5.1

It is possible to list all of the versions of pyramids available on your platform with:

conda search pyramids --channel conda-forge

0.5.0 (2023-10-01)

Dataset """""""

• The dtype attribure is not initialized in the init, but initialized when using the dtype property.
• Create band_names setter method.
• add gdal_dtype, numpy_dtype, and dtype arrtibute to change between the dtype (data type general name), and the coresponding data type in numpy and gdal.
• Create color_table attribure, getter & setter property to set a symbology (assign color to different values in each band).
• The read_array method returns array with the same type as the dtype of the first band in the raster.
• add a setter method to the band_names property.
• The methods (create_driver_from_scratch, get_band_names) is converted to private method.
• The no_data_value check the dtype before setting any value.
• The convert_longitude used the gdal.Wrap method instead of making the calculation step by step.
• The to_polygon is converted to _band_to_polygon private method used in the clusters method.
• The to_geodataframe is converted to to_feature_collection. change the backend of the function to use the crop function is a vector mask is given.
• the to_crs takes an extra parameter "inplace".
• The locate_points is converted to map_to_array_coordinates.
• Create array_to_map_coordinates to translate the array indices into real map coordinates.

DataCube """"""""

• rename the read_separate_files to read_multiple_files, and enable it to use regex strigs to filter files in a given directory.
• rename read_dataset to open_datacube.
• rename the data attribute to values

FeatureCollection """""""""""""""""

• Add a pivot_point attribure to return the top left corner/first coordinates of the polygon.
• Add a layers_count property to return the number of layers in the file.
• Add a layer_names property to return the layers names.

• Add the file_name property to store the file name.
• Add the dtypes property to retrieve the data types of the columns in the file.
• Rename bounds to total_bounds.
• The _gdf_to_ds can convert the GeoDataFrame to a ogr.DataSource and to a gdal.Dataset.
• The create_point method returns a shapely point object or a GeoDataFrame if an epsg number is given.

0.5.1 (2023-11-27)

Dataset """""""

• revert the convert_longitude method to not use the gdal_wrap method as it is not working with the new version of gdal (newer tan 3.7.1).
• bump up versions.
