Geospatial Machine Learning Workflows in Databricks

As the volume of geospatial data increases exponentially, the need for scalable and efficient machine learning workflows in distributed environments becomes essential. Databricks, with its unified analytics platform and built-in support for big data processing, has emerged as a powerful tool for developing, training, and deploying geospatial machine learning (GeoML) models.

Why Geospatial ML Needs Scalable Infrastructure


When working with high-resolution remote sensing, telemetry, or Internet of Things datasets, traditional GIS tools frequently fail. Workloads requiring geospatial machine learning are intrinsically data- and compute-intensive and include:


  • Ingestion of raster/vector data at the petabyte scale

  • Indexing, tiling, and spatial joins

  • Engineering features across space-time grids

  • Training models with spatial autocorrelation-aware techniques

  • Real-time and batch inference across dispersed spatial domains


These issues are resolved by Databricks using Delta Lake storage, parallelized computation (Spark), and smooth machine learning integration.


Core Components of a Geospatial ML Workflow in Databricks


1. Preprocessing and Data Ingestion


Databricks supports scalable geospatial format ingestion and includes:


  • Shapefiles, GeoJSON, and KML (via GDAL or GeoMesa)

  • Raster data (using Xarray-PySpark or RasterFrames for GeoTIFF, HDF5, and NetCDF)

  • Data streaming from IoT sensors and Kafka (with spatial-temporal keys)


Data can be spatially indexed and partitioned using Apache Sedona (formerly known as GeoSpark) or H3. Through partition pruning, Delta Lake facilitates effective spatial querying and ACID transactions.


2. Engineering Spatial Features


One way to incorporate spatial context is by using:


  • Satellite imagery's NDVI and SAVI (using RasterFrames)

  • Features based on proximity using spatial joins

  • Aggregations based on the H3 hex


Utilizing sliding window functions for temporal aggregations


3. Experimentation and Model Training


Models can be trained at scale with Databricks Runtime ML by using:


  • For scalable pipelines, Spark MLlib

  • HorovodRunner, LightGBM, and XGBoost

  • For deep spatial models, such as CNNs on tiles, TensorFlow/PyTorch


4. Model Assessment Using Spatial Measures


The i.i.d. premise is broken by spatial autocorrelation. Apply validation that is spatially aware:


  • Block cross-validation (test tiles that are not adjacent)

  • Geary's C and Moran's I for testing spatial residuals

  • Visual examination using confusion matrices over map tiles or heatmaps


5. Inference in Batch and Real-Time


Apply models across wide geographic areas using Databricks:


  • Using transform() to score Delta tables in batches

  • Inference streaming from IoT or UAV data

  • Real-time serving with Databricks Model Serving + REST APIs


Advanced Use Cases


  • Using thermal images to detect urban heat islands

  • Monitoring deforestation with temporal NDVI change

  • Predicting traffic accidents with point-in-polygon joins.

  • Estimating soil moisture using combined sensor and satellite data


Best Practices for Geospatial ML on Databricks


  • Optimize spatial reads by using the Delta Lake ZORDER BY H3 index.

  • To prevent recomputation, cache intermediate tiles and features.

  • Use Databricks Jobs + Notebooks to automate processes.

  • Track model drift using MLflow Data versioning and the Model Registry


A production-grade, scalable platform for creating geospatial machine learning processes is offered by Databricks. It enables data scientists and spatial analysts to transcend conventional GIS silos and advance toward real-time, AI-powered geospatial intelligence with native support for Spark, Sedona, RasterFrames, MLflow, and deep learning libraries.
