PostGIS

Making spatial data work for real business applications

Location data is everywhere: delivery routes, service areas, utility lines, customer addresses, traffic zones, and emergency coverage maps. And when that data matters to your operations, you can’t afford to treat it like an afterthought.

PostgreSQL isn’t built to handle geospatial logic. Basic location queries can become slow and imprecise. Writing spatial logic in application code or offloading it to third-party GIS systems often leads to sync issues, added complexity, and scattered data ownership.

However, PostGIS brings native spatial capabilities into PostgreSQL. That means the database you’re already using can now store, query, and analyze geographic data efficiently and at scale. You’re not just adding a new feature. You’re unlocking an entirely new category of insight that would otherwise require separate tools or painful workarounds.

With PostGIS, your database can answer questions like:

  • Which customers are within five miles of this location?
  • What delivery zones overlap with this zip code?
  • Is this route passing through a restricted area?
  • What’s the nearest service center to a given coordinate?

These aren’t edge cases. They’re everyday questions for industries like transportation, logistics, utilities, healthcare, telecom, and government, especially when accuracy, auditability, and performance matter.

Why PostGIS is essential for enterprise workloads

1. It keeps spatial queries fast, even at scale

PostGIS includes specialized spatial indexes that are purpose-built for geodata. You can sort, filter, and analyze millions of records without watching your queries grind to a halt. That’s a huge step up from trying to force standard indexes to do spatial work they weren’t designed for.

2. It cuts out system sprawl

PostGIS keeps everything inside your PostgreSQL environment, from your spatial data to your business logic to your operational monitoring. No external GIS tools, no extra infrastructure, and no separate systems to secure, sync, or troubleshoot.

3. It fits cleanly into modern infrastructure

Traditional GIS solutions often feel clunky in cloud-native environments. PostGIS plays nicely with containerized PostgreSQL and Kubernetes-based deployments, making it easy to scale as part of your broader platform strategy.

4. It supports secure, regulated environments

For industries with compliance requirements, PostGIS offers a way to keep geospatial data in the same secure, auditable database environment as the rest of your business-critical information. No need to push sensitive location data into a third-party system.

5. It avoids hidden costs and licensing headaches

PostGIS is fully open source, so there’s no separate licensing, no usage restrictions, and no premium tiers that limit what your team can do. You scale as your data grows, without surprise fees down the line.

Your options for running PostGIS

PostGIS is widely supported and available, but how you deploy it matters, especially if you're planning for scale, compliance, or long-term maintainability.

Option 1: Manual installation

You can install PostGIS yourself using standard package managers. This gives you control but also adds operational overhead. Your team is responsible for compatibility checks, upgrades, extension conflicts, and integration with HA, backups, and monitoring tools. If you’re already managing multiple extensions, the DIY approach can introduce risk and complexity quickly.

Option 2: Commercial PostgreSQL vendors

Some proprietary PostgreSQL vendors bundle PostGIS into their paid offerings. While this may reduce setup time, it often comes with trade-offs: gated features, licensing fees, cloud lock-in, or limits on how and where you can run your database. You get spatial functionality but at the cost of long-term flexibility and potentially higher TCO.

Option 3: Use PostGIS as part of an open source PostgreSQL solution

PostGIS is included in Percona’s enterprise-ready PostgreSQL solution and has been tested to work alongside other critical components like HA, backup, and observability tools. There are no additional license fees, and it’s ready to run in modern infrastructure, including Kubernetes environments. Your spatial workloads get first-class support, without the integration or lock-in headaches.

Ready for real-world demands

PostGIS turns PostgreSQL into a powerful spatial database capable of answering complex location-based questions right where your business data lives. Whether you’re supporting logistics, infrastructure, or compliance-heavy use cases, it’s the piece that makes geospatial data fast, accurate, and actionable without adding complexity to your stack.
