Build a geospatial lakehouse on Databricks with native spatial SQL and H3 for vector work, governed file workflows for raster, and one catalog over all of it.

Most spatial teams already have working pipelines, databases, files, and specialist tools. The difficulty appears when those systems apply different access rules, maintain separate lineage, or make spatial results hard to combine with business data. A [geospatial lakehouse](https://lakegeo.ai/learn/what-is-a-geospatial-lakehouse/) brings those workloads under the same governance and operating model without requiring every workload to use the same processing tool.

On Databricks, the practical task is deciding where each kind of work belongs. Vector analysis can move into shared tables and compute, while imagery and point-cloud processing can remain file-based workflows with explicit owners. The result depends on placing each capability within the platform rather than forcing every capability into one engine.

_One platform: the native vector path and the operated raster path side by side, under one catalog, one lineage, and one access model._

## Which spatial work belongs inside the platform?

The dividing line is what Databricks can represent natively. Delta tables, the platform’s governed table format, support native GEOMETRY and GEOGRAPHY columns. GEOMETRY uses a planar coordinate model. GEOGRAPHY uses a spherical coordinate model. The ST\_ family of spatial SQL functions operates on those columns, including optimized spatial joins.

The platform also provides native H3 functions. H3 is a hexagonal discrete global grid system that assigns locations to cells at multiple resolutions. Its functions support cell assignment, coverage, neighborhood analysis, hierarchy operations, and joins that first use grid cells to reduce the locations that must be compared.

Raster and point-cloud work take a different route. Unity Catalog volumes hold the governed files, while Delta tables record metadata and lineage. Distributed Python workflows run rasterio and the Geospatial Data Abstraction Library (GDAL) across those files. These workflows remain part of the governed platform even though the platform does not provide native raster or point-cloud types.

This arrangement can replace separate PostGIS servers, desktop geographic information system handoffs, and contractor-operated imagery pipelines when those systems duplicate governance or isolate spatial results from business data. Specialist engines can remain where they supply a missing capability. Their inputs, outputs, access rules, and operational owners should still connect to the shared catalog.

## How do the six platform layers fit together?

The [Geospatial Lakehouse Stack](https://lakegeo.ai/learn/what-is-the-geospatial-lakehouse-stack/) separates the architecture into six layers. On Databricks, each layer maps to a specific group of services.

The ingestion layer brings data into the platform. Auto Loader monitors arriving files, Lakeflow Connect handles managed data sources, and Structured Streaming processes live feeds.

The storage and governance layer establishes the system of record. Delta tables store tabular data and native spatial columns. Unity Catalog provides discovery, lineage, and access control. Unity Catalog volumes hold raster and point-cloud files. Delta Sharing and Marketplace distribute governed products to other users and organizations.

The spatial compute layer performs analysis. Native spatial SQL handles geometry operations and joins, while H3 supports grid-based analysis. GraphFrames provides graph analytics. Distributed Python workflows use rasterio and GDAL for raster processing.

The machine learning and AI layer builds from the same governed products. Feature Engineering in Unity Catalog manages reusable features. MLflow and Models in Unity Catalog track and govern models. Mosaic AI Model Serving runs registered models for consumers. Databricks Vector Search supports retrieval over indexed content.

The orchestration layer keeps work repeatable. Lakeflow Declarative Pipelines manages transformations. Lakeflow Jobs handles schedules, dependencies, retries, and operational control.

The consumption layer gives users and applications access to results. AI/BI Dashboards and Genie support analysis. Databricks Apps provides custom interfaces, while Lakebase serves applications that need low-latency access. Delta Sharing supplies governed data to partners.

## How does data move from arrival to use?

The [Geospatial Medallion Architecture](https://lakegeo.ai/learn/what-is-the-geospatial-medallion-architecture/) begins with acquisition. Lakeflow Connect collects managed sources, Auto Loader receives delivered files, and notebooks or jobs interact with provider catalogs and ordering interfaces.

The bronze stage preserves source material. Files remain in write-once Unity Catalog volume paths. Tabular sources enter bronze Delta tables without changing source values in place.

The silver stage prepares data for analysis. Rasterio and GDAL convert raster files into cloud-optimized layouts. Vector workflows validate and transform geometry. They can also add spatial indexes, which are structures that reduce the locations a downstream join must compare.

The gold stage publishes governed products with defined business meaning. Delta tables hold those products, while Unity Catalog registers reusable features and models.

The serving stage connects products to their consumers. Dashboards and Genie support analysis. Databricks Apps and Lakebase support applications. Delta Sharing and Marketplace handle external distribution. Together, these stages carry data from provider acquisition to consumer serving through services that share governance and lineage.

## What changes when spatial work shares the platform?

Databricks is strongest when spatial work must connect directly to other production data. Spatial SQL, H3 analysis, graph processing, and distributed raster workflows can use the same compute platform. Teams do not have to copy vector results into a separate spatial database before joining them to customer, asset, or operational tables.

Unity Catalog also governs spatial tables and raster files together. Access rules, discovery, and lineage can therefore cover both native columns and file-based workflows. Optimized spatial joins and native H3 functions keep large vector enrichment jobs inside the platform.

The benefit continues beyond spatial processing. Machine learning workflows use the governed products created by the spatial pipelines. Dashboards, custom applications, and sharing services consume those same products. This keeps spatial analysis connected to the platform’s established data, model, and application practices.

## What limits require explicit decisions?

Databricks has no native raster, point-cloud, topology, or weighted-routing type. Teams must build and operate those workflows through files, Python functions, or external engines. Each workflow needs a named owner for failures, upgrades, cost, and output quality.

Long-distance calculations require a deliberate choice between GEOMETRY and GEOGRAPHY. The correct choice depends on the coordinate model and the functions required by the workload.

Large raster jobs and machine learning jobs need workload-specific cost and performance testing. General platform capacity does not remove the need to test representative data and processing patterns.

Some applications may also require a dedicated low-latency serving store. Lakebase can fill that role while Delta tables remain the governed source, but the serving design should follow the application’s response requirements.

## Where should a team begin?

A build that begins with a flagship pipeline usually discovers its platform decisions too late. Begin instead by classifying existing workloads according to the primitives they require. Put vector operations that fit spatial SQL into native spatial columns and functions. Use H3 where grid assignment, coverage, neighborhoods, hierarchy, or grid-filtered joins match the analysis.

Keep raster, point-cloud, topology, and routing work in governed file workflows or specialist engines. Record their metadata and outputs in Delta tables where appropriate. Assign an operational owner to every workflow that the platform does not manage natively.
