PROFILE
Naoto Akiyama
Over the past year, contributed to the reearth-flow repository by engineering robust geospatial data processing workflows and automated quality assurance pipelines. Leveraging Rust, YAML, and XML, developed and maintained features for 3D data conversion, validation, and CityGML processing, while implementing modular, test-driven approaches to ensure code reliability and maintainability. Enhanced CI/CD pipelines, improved schema handling, and introduced secure configuration management to support scalable, production-ready deployments. Addressed complex data validation challenges, expanded output formats, and strengthened documentation for developer onboarding. The work emphasized code hygiene, workflow automation, and security, resulting in more reliable data pipelines and streamlined contributor collaboration.

Jan 1, 2026January 2026 (2026-01) monthly summary for reearth-flow focusing on delivering robust data workflows, fixing quality checks, and expanding output formats. Key features delivered include WaterBody Quality Check Workflow Improvements with enhanced geometry validation, surface error handling, multi-file summary outputs, and comprehensive tests; 3D Tiles (construction data) and MVT (bridge geometry) outputs generation with associated tests and workflow examples; and PLATEAU v5 compatibility updates to ensure forward compatibility and smoother migrations. Major bugs fixed include QC error counting corrections to align with FME behavior by excluding adjacent surface overlaps in tran QC and excluding invalid holes in DEM QC. Workflow and testing improvements include adding a new 05-fld target to the generate-examples-cms-workflow, enhancing 06-fld QC workflow output naming with tests, migrating workflow test configurations, and addressing flaky tests with version bumps across Cargo.toml to improve reliability. Overall impact includes higher data integrity, more reliable and scalable data pipelines, expanded output formats for downstream ecosystems, and stronger engineering discipline around testing and versioning. Technologies/skills demonstrated include Rust-based engine work, test-driven development, cargo-make automation, workflow scripting, data schema and codelist corrections, 3D Tiles/MVT pipelines, and cross-repo compatibility with PLATEAU v5. The month delivered tangible business value by reducing downstream data quality risks, enabling richer data products, and accelerating deployment readiness for PLATEAU v5 and related workflows.

Sep 1, 2025September 2025 monthly summary for reearth/reearth-flow focusing on delivering business value through robust surface validation, data quality improvements, and QA automation. Key milestones include consolidating 2D/3D surface validation into a unified framework, expanding validation coverage with 2D duplicate-points checks and a 3D sub-workflow, and centralizing surface validation configuration across the engine (with tests and attribute handling). Added PLATEAU4.DestinationMeshCodeExtractor to compute and store legitimate regional mesh codes and validate assignments. Strengthened QA with dedicated data for PLATEAU quality checks and a new test-wf sub-command, plus reorganization of test data directories. Documentation updated to require Python 3.11+ for Python-based actions and to streamline OS-specific install steps, removing py2wasm as a main dependency. These efforts deliver higher data quality, improved validation reliability, faster QA feedback, and clearer contributor guidance.
