Let's dive in!
Why Use PostGIS for Your Geospatial Data?
PostGIS extends PostgreSQL to handle spatial data, offering significant advantages over file-based systems such as storing data as loose GeoJSONs in your filesystem. Let’s go over some of the advantages:
- Scalability and Performance: PostGIS efficiently manages large datasets with spatial indexing, enabling fast queries even as your data grows. With a file based system, your system’s performance might slow down with each addition.
- Advanced Spatial Analysis: Leverage PostGIS's extensive suite of spatial functions and SQL capabilities for complex geospatial operations. PostGIS has been built from the ground up to understand and operate on geospatial data; with a file-based system, you’ll have to write your own code.
- Multi-user Collaboration: PostGIS supports concurrent access, allowing team members to work simultaneously on the same dataset.
- Data Integrity and Security: Benefit from PostgreSQL's robust data validation, access controls, and transaction management. Storing your data in a database will make sure all your data is structured similarly, significantly lowering your costs down the line.
- Cloud-Ready Architecture: PostGIS is designed for cloud environments, facilitating scalable, distributed GIS operations crucial for platforms like Felt.
By adopting PostGIS, you're not just changing data storage – you're upgrading your entire GIS infrastructure to be more robust, scalable, and ready for modern, cloud-based workflows.
Why Choose a Cloud PostGIS Solution?
Opting for a cloud PostGIS solution offers several advantages over self-hosting:
- Simplified setup and maintenance: No need to worry about server configuration, software installation, or database administration tasks.
- Automatic updates and security patches: Providers ensure your database is always running the latest, most secure version.
- Scalability and performance optimization: Easily scale your resources as your needs grow, with optimizations handled by experts.
- Built-in backups and disaster recovery: Regular backups and point-in-time recovery options protect your valuable data.
- Cost-effectiveness: Often more economical, especially when considering the total cost of ownership including maintenance and operations.
Key Considerations When Choosing a Cloud PostGIS Solution
When evaluating cloud PostGIS options, keep these factors in mind:
- Performance and scalability: Consider database size limits, query performance, and the ability to handle concurrent connections.
- Geospatial features support: Check the PostGIS version and supported functions, as well as spatial indexing capabilities.
- Security and compliance: Look for data encryption at rest and in transit, as well as relevant compliance certifications (e.g., GDPR, HIPAA).
- Integration capabilities: Ensure easy connection with Felt and compatibility with other tools in your stack.
- Pricing model: Compare pay-per-use vs. fixed pricing, and check for additional costs like backups or data transfer.
- Management features: Evaluate monitoring and analytics tools, and the ease of performing common database operations.

Setting Up Your Chosen PostGIS Solution for Felt
Once you've selected a cloud PostGIS solution, follow these steps to set it up for optimal use with Felt. We'll pay special attention to security and monitoring considerations that are particularly important when integrating with external services like Felt.
- Create your database: Follow the provider-specific instructions to create your PostgreSQL database.
- Enable PostGIS: Connect to your database and run:
- Create a Felt-specific user: Creating a dedicated user for Felt is crucial for security and monitoring. Here's why:
- Enhanced Security: A dedicated user with limited permissions reduces the risk of unauthorized data access or modifications.
- Easier Monitoring: You can track all database activities specific to Felt, making it easier to optimize performance and troubleshoot issues.
- Simplified Auditing: In case of any data discrepancies, you can quickly audit actions performed by the Felt user.
Create the user with read-only permissions.
Note: We are not adding write permissions just yet; Felt does not write data to your cloud. However, always start with the principle of least privilege and only add permissions as necessary.
- Set up your data: Create tables with geometry or geography columns as needed. For example:
- Connect Felt to your database: In Felt, navigate to the data source configuration and enter your PostGIS connection details:
- Host: Your database server address
- Port: Typically 5432 for PostgreSQL
- Database: Your database name
- Username: felt_user
- Password: your_secure_password
- Implement additional security measures: While creating a dedicated user is a good start, consider these additional security measures:
- SL Connections: Ensure that all connections between Felt and your database are encrypted using SSL.
- Regular Password Rotation: Implement a policy to regularly update the felt_user password. Remember to update the connection details in Felt when you do this.
- IP Allowlisting: Restrict database access to only Felt's IP addresses. This significantly reduces the risk of unauthorized access attempts. Felt can provide you with their IP ranges for this purpose.
Example for PostgreSQL (in pg_hba.conf):
Remember to consult your hosting provider's documentation for specific instructions on implementing these security measures, as the exact steps may vary between providers.
Best Practices for Using Cloud PostGIS with Felt
To get the most out of your cloud PostGIS and Felt setup:
- Regularly monitor performance: Use your provider's monitoring tools to keep an eye on database performance and resource usage.
- Optimize your queries: Use EXPLAIN ANALYZE to understand and improve your query performance, especially for complex spatial operations.
- Keep your PostGIS version up-to-date: Stay current with the latest PostGIS version supported by your provider to access new features and optimizations.
- Manage costs effectively: Monitor your usage and adjust your plan or resources as needed to optimize costs.
- Use appropriate indexes: Create spatial indexes on your geometry columns to speed up spatial queries:
Summary
Choosing a cloud PostGIS solution for use with Felt can significantly simplify your GIS workflow, allowing you to focus on analysis and visualization rather than database management. By considering factors like performance, scalability, and integration capabilities, you can select the right solution for your needs.
Remember, the best choice will depend on your specific use case, existing technology stack, and scalability requirements. Whichever solution you choose, the combination of PostGIS and Felt provides a powerful foundation for your geospatial projects in the modern GIS stack.
