For utility corporations equivalent to Xcel Vitality, wildfire mitigation is vital to defending electrical infrastructure and minimizing the chance of utility-related ignition occasions. Typical mitigation methods embody vegetation administration, grid hardening, threat assessments, public security energy shutoffs (PSPS), and leveraging superior applied sciences like AI and sensors. A standard problem for this use case is the evaluation of geospatial knowledge at the side of the structured knowledge out there. Geospatial evaluation includes learning knowledge linked to particular areas on Earth, which is essential for understanding varied phenomena and interactions. Frequent examples embody navigation apps, geotagged images, and climate maps. Nonetheless, working with geospatial knowledge presents challenges concerning knowledge privateness and placement monitoring, the necessity for advanced software program instruments to deal with varied knowledge codecs (like GeoJSON and Shapefile), and the administration of enormous datasets that may be computationally intensive. Moreover, challenges round accuracy and distortion can come up when merging knowledge from totally different sources on account of various coordinate programs and measurement models. Regardless of these complexities, geospatial knowledge performs an important position in Xcel Vitality’s technique and operations. To completely leverage this important knowledge, an answer that overcomes these challenges is required to allow efficient integration and evaluation of geospatial insights to handle wildfire dangers.
Use Case:
Wildfire Mitigation is a serious initiative for Xcel Vitality, with $500 million invested in wildfire mitigation actions since 2020. Xcel Vitality has proposed a multifaceted technique in its 2025-2027 Wildfire Mitigation Plan for Colorado, which incorporates system upkeep and upgrades, operational preventative measures, and broad situational consciousness. These efforts depend on superior geospatial and machine studying fashions to calculate wildfire threat metrics based mostly on real-time climate forecasts. In collaboration with Nousot, Xcel Vitality makes use of the Databricks Information Intelligence Platform and geospatial libraries like H3 indexing to remodel advanced climate knowledge into simplified tabular outputs.

Performing Geospatial Analytics on the Databricks Platform
The ability of performing geospatial analytics on the Databricks Platform is within the resolution’s excessive efficiency, accuracy, and scalability. Xcel Vitality can extra effectively course of and analyze a whole bunch of enormous climate information—many containing a number of knowledge bands—in underneath an hour. This feat would have been nearly unattainable with legacy GIS programs. Such functionality permits meteorology and asset administration stakeholders to make well timed, knowledgeable selections to mitigate the chance of wildfires sparked by electrical belongings. In 2025, Xcel Vitality plans to leverage the tabular outputs of this course of to coach machine studying fashions that may assist predict hearth dangers and energy outages.
The next instance demonstrates how the Databricks Platform helps geospatial analytics, utilizing the Wildland Hearth Potential Index (WFPI) as calculated by the US Geological Survey (USGS). USGS releases 7 days of WFPI forecasts day by day, which Xcel Vitality makes use of as part of their arithmetic and AI wildfire threat modeling. A map of WFPI measurements in the US is proven in Determine 1 beneath. Yellow and purple pixels point out excessive hearth threat, inexperienced reveals decrease threat, and gray/white areas symbolize unmeasured areas like agricultural land or snow. Contemplating the delicate nature of Xcel Vitality’s asset knowledge, this instance makes use of the State of Oregon as a proxy (Xcel Vitality doesn’t function in Oregon).
Geospatial picture knowledge typically covers monumental areas, as proven in Determine 1. Performing H3 indexing at fine-grain resolutions over such a big space could be computationally costly and sometimes pointless; Xcel Vitality solely must course of the geographic areas during which their belongings reside. To handle this, the following step is to “crop” the preliminary picture and concentrate on areas of curiosity. We then calculate Wildland Hearth Potential Index (WFPI) values for every H3 hexagon on the desired decision throughout the space of curiosity. These H3 values can then be saved in Delta Reside Desk or visualized with Python libraries. Staying with theState of Oregon instance, Determine 2 is a visualization of the cropped and listed WFPI threat ranges for a specific summer season day. Word that the visualization could be generated in a Databricks Pocket book or on Databricks Apps.
For example the spatial decision of H3, let’s zoom in on the realm highlighted by the inexperienced field.
At H3 decision 7, every hexagon covers roughly 5.16 sq. kilometers with a facet size of about 1.41 km.
Many options of the visualization are customizable; on this instance, the measured hearth potential values are mapped to the identical colours as the unique picture. Discover the sharp contrasts in colour between bordering hexagons. These variations in WFPI spotlight the accuracy enabled by the H3 indexing system.
This similar course of is repeated for quite a few climate forecasts and observations, together with a number of Xcel Vitality asset sorts. The result’s a set of environmental and asset knowledge, all in the identical H3 area. This knowledge serves as a robust basis for coaching ML and GenAI fashions. There are a number of areas of impression for Wildfire AI. These embody utilizing Massive Language Fashions (LLMs) to evaluation work order notes and outage experiences from subject crews to find out if an ignition occasion occurred, equivalent to sparking. Sparking is often on account of contact with dry vegetation, downed wires, or malfunctioning gear, and will probably begin fires. The LLMs are logged in MLflow for improvement, experiment monitoring, and administration. The LLMs could be productionized for real-time inference with Mosaic AI Mannequin Serving. This GenAI powered method achieves 100% knowledge completeness for outage occasions, a transformative enchancment over the earlier handbook course of, which captured solely 30%—eliminating vital knowledge gaps, saving workers hours, and enhancing operational capabilities. A number of different AI/ML fashions are at the moment being designed to foretell and simulate a variety of eventualities, together with predicting asset ignition chance.Interactions with H3 knowledge utilizing pure language are made straightforward with Databricks instruments equivalent to AI/BI Genie and AI Features.
This method simply scales on Databricks and unlocks AI by accelerating ML mannequin supply.

Superior Geospatial Evaluation
Rasters (equivalent to climate forecast maps and satellite tv for pc photos) could be tougher to work with. In a raster every pixel within the picture represents a measurement over a particular geospatial space. For instance, the ERA5 climatology dataset comprises estimates of atmospheric, land, and oceanic local weather variables at a spatial decision of 30km per pixel. The NOAA Operational Mannequin Archive and Distribution System (NOMADS) mission permits sharing of information and fashions from a number of companies and establishments, equivalent to atmospheric forecasts in a number of totally different resolutions. Rasters from these companies can include a number of layers or bands of information in the identical file, which means that there could be separate bands for floor temperature, wind velocity, and relative humidity, and be in a variety of file codecs together with GeoTIFF, NetCDF, GRIB, and HDF4/5.
The databricks-mosaic library from Databricks Labs helps interplay with these advanced file sorts in addition to rising raster assist from a successor mission, spatial-utils. Databricks-mosaic is a scalable geospatial extension for Apache Spark™ that brings collectively the capabilities of a number of open-source frameworks. The library has capabilities to learn file and band metadata, extract the specified bands, and carry out H3 indexing on rasters in addition to take measurements (min, max, common, or median) of pixel values inside every H3 cell. This course of turns advanced rasters into easy tabular knowledge.
