Concise monthly summary for 2026-05 highlighting key features delivered, major bugs fixed, impact, and technologies demonstrated across GeoNet/delta and GeoNet/base-images.

April 2026 performance summary for GeoNet/delta. Focused on delivering robust improvements to the marking workflow and data integrity across deployments. Implemented enhancements to support multiple mark locations and multiple time-bound marks per location, added overlap checks, and updated constraints to improve flexibility and accuracy. Also resolved legacy constraints that limited marks per code, enabling richer marking scenarios and more reliable analytics.

March 2026: Delivered foundational database infrastructure and strengthened code quality across two repos. Established a Seiscomp PostgreSQL base image to standardize and accelerate database builds. Updated code to satisfy newer lint checks, replaced deprecated functions, and enhanced error handling, improving reliability and maintainability. This work reduces onboarding and build time, minimizes runtime errors, and supports future releases. Technologies demonstrated include Docker-based image creation, PostgreSQL deployment, static code analysis, and robust error handling.

Month: 2025-11 — GeoNet/delta focused on security posture and dependency compatibility by upgrading the Go runtime. The change addressed vulnerability checks and ensured alignment with dependencies, reducing risk and keeping the stack current.

October 2025 monthly summary for GeoNet/base-images focusing on expanding Docker image synchronization to support RisingWave and MQTT test deployments. No major bugs fixed this month. Delivered two image synchronization enhancements with clear version pinning, improving environment parity and repeatable deployments.

GeoNet/base-images Sep 2025: Delivered observability base-image enhancements by adding vmagent, Alertmanager, and vmalert images, updated CI/CD integration and documentation, enabling faster rollout and improved self-monitoring for downstream services.

August 2025: Delivered a key observability enhancement by integrating Victoria Logs through a new image in the synchronization configuration for the GeoNet/base-images repository. The addition of the victoria-logs image (v1.28.0) enables logging integration within the Victoria Metrics ecosystem, supporting improved monitoring and faster issue resolution. All changes were feature-driven with careful consideration to maintain backward compatibility; no user-facing regressions observed.

July 2025 performance summary for GeoNet/delta focused on reliability, configuration completeness, and data integrity across import, sensor configuration, camera validation, and network date generation. Delivered targeted fixes and enhancements that improve data quality, network recognition, and processing efficiency.

May 2025 monthly summary for GeoNet engineering: Summary of work focused on data model modernization, site-specific data processing workflows, data quality improvements, and deployment automation. Delivered cross-repo features that unify location data representation, enable configurable gauge processing, standardize sensor naming, extend the schema with a notes capability, and strengthen deployment consistency for Victoria Metrics. Key outcomes include a more discoverable and analyzable data model, robust site-specific processing configurations, improved data quality across CSV datasets, and streamlined deployment processes.

This month (April 2025) for GeoNet/delta focused on improving camera metadata presentation and hardening sensor configuration validation. The team delivered a refined caption for the Taranaki volcanic camera view to more accurately reflect location (New Plymouth) and added boundary checks to ensure cameras are positioned within their designated views and within mount bounds. The changes reduce mislabeling, prevent out-of-scope captures, and improve data quality and maintenance traceability, aligning with business goals of accurate data display and reliable surveillance capabilities.

January 2025 (2025-01) monthly summary: Delivered core platform reliability and data quality enhancements across base-images and delta. Key features delivered include Ringserver image synchronization support (4.0.0) and upgrade to 4.0.1 in CI/CD, plus a critical typo fix in the sync config. Platform stability improvements were achieved via Go toolchain upgrades and protobuf dependency updates. Data integrity and configuration accuracy were improved through dataset naming, timing windows, and installation timing refinements. Database initialization was hardened with a robust Init flow and delta.DB type. These changes collectively reduce deployment risk, improve cross-service compatibility, and enhance data accuracy for operations and analytics.

November 2024 (GeoNet/delta) focused on strengthening the core Deltadb storage layer to deliver real business value through stronger data integrity, transactional guarantees, and maintainability. Key work spanned core database enhancements, reliability improvements, and documentation/ownership updates, with a clear path to easier onboarding and faster iteration on data features.

GeoNet/delta 2024-09 monthly summary: Delivered core data-model enhancements to enable structured data management and future integration with tilde, with concrete schema changes and test coverage, and no major bug fixes this period.

July 2024 — GeoNet/delta: Delivered key improvements focusing on maintainability and data integrity. Removed deprecated RINEX XML generation to reduce technical debt and simplify the codebase, and introduced robust equipment installation date validations to prevent incorrect status changes. These changes enhance data reliability in the delta repository and reduce maintenance overhead for future features, supporting more predictable deployments and downstream analytics.

June 2023 Monthly Summary for GeoNet/delta focusing on delivering core data capabilities and strengthening data governance. The primary delivery was Environmental Notes Management, introducing a new Note data structure with encoding/decoding and integrating environmental notes storage and management into the data handling workflow. This work lays the foundation for richer environmental data capture, traceability, and analytics.
