Geoconda is a collection of python packages that facilitate the development of python scripts for geoinformatics applications. It includes following python packages:

  • ArcGIS Python API - provides simple and efficient tools for sophisticated vector and raster analysis, geocoding, map making, routing and directions.
  • boto3 - for working files in S3 storage, for example Allas. Example.
  • cartopy - for map plotting.
  • dask - provides advanced parallelism for analytics, enabling performance at scale, including Dask-ML and Dask JupyterLab extension
  • descartes - use Shapely or GeoJSON-like geometric objects as matplotlib paths and patches.
  • fiona - reads and writes spatial data files.
  • gdal - reads and writes spatial data files, and GDAL/OGR data manipulation tools.
  • geoalchemy2 - provides extensions to SQLAlchemy for working with spatial databases, primarily PostGIS.
  • geopandas - GeoPandas extends the datatypes used by pandas.
  • igraph - for fast routing.
  • jupyter - Jupyter Notebooks and JupyterLab, CSC RStudio and Jupyter Notebooks tutorial describes how to use these with Puhti
  • laspy
  • laxpy
  • networkx - for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.
  • pyproj - performs cartographic transformations and geodetic computations.
  • osmnx - download spatial geometries and construct, project, visualize, and analyze street networks from OpenStreetMap's APIs.
  • pysal - spatial analysis functions.
  • pdal - for lidar data
  • rasterio - access to geospatial raster data.
  • rasterstats - for summarizing geospatial raster datasets based on vector geometries. It includes functions for zonal statistics and interpolated point queries.
  • rtree - spatial indexing and search.
  • sentinelsat - downloading Sentinel images
  • shapely - manipulation and analysis of geometric objects in the Cartesian plane.
  • scipy - inc pandas, numpy, matplotlib etc
  • scikit-learn - machine learning for Python.
  • skimage - algorithms for image processing.
  • swiftclient, keystoneclient - for working with SWIFT storage, for example Allas.
  • xarray - for multidimensional raster data.
  • And many more, for retrieving the full list in Puhti use: list-packages

Additionally geoconda includes:

  • spyder - Scientific Python Development Environment with graphical interface (similar to RStudio for R).
  • GDAL/OGR commandline tools 3.2.1 in geoconda-3.8.8, 3.0.4 in geoconda-3.8 and 3.0.2 in geoconda-3.7
  • GMT The Generic Mapping Tools in geoconda 3.8 and 3.8.8.
  • PDAL 2.2.0 in geoconda-3.8.8, 2.1.0 in geoconda-3.8 and 2.0.1 in geoconda-3.7
  • QGIS only in geoconda 3.8 and 3.7, latest version in own qgis module.
  • LasTools only in geoconda 3.8 and 3.7, latest version in own lastools module.
  • ncview for visualizing netcdf files
  • proj4, geos and many more, see /appl/soft/geo/geoconda/miniconda3/envs/geoconda-3.x/bin or /appl/soft/geo/conda/singularity/geoconda/2021/bin for full list.


If you want to use Spyder, ncview or other tools with graphical user interfaces, you should connect to Puhti using NoMachine and start an interactive session for best performance. You can also edit and run Python code remotely with some code editors like Visual Studio Code

Python has multiple packages for parallel computing, for example multiprocessing, joblib and dask. In our Puhti Python examples there are examples how to utilize these different parallelisation libraries.

(If you think that some important GIS package for Python is missing from here, you can ask for installation from


The geoconda module is available in Puhti:

  • 3.8.8 (Singularity installation with wrappers, so should be hidden from users in normal use-cases)
  • 3.8
  • 3.7

Version number is the same as Python version.


For using Python packages and other tools listed above, you can initialize them with:

module load geoconda

By default the latest geoconda module is loaded. If you want a specific version you can specify the version number of geoconda:

module load geoconda/[VERSION]

For using the Spyder IDE give:


To check the exact packages and versions included in the loaded module:


You can add more Python packages to Geoconda, see instructions from CSC Python page.

Using Allas from Python

There are two Python libraries installed in Geoconda that can interact with Allas. Swiftclient uses the swift protocol and boto3 uses S3 protocol. You can find CSC examples how to use both here. With large quantities of data in Allas, virtual rasters should be considered. More information on how to create and use virtual rasters can be found here.
