Stein
Stein Kobben developed advanced 3D mapping and filtering features for the Tailormap/tailormap-viewer repository, focusing on robust user experience and maintainable architecture. Over 11 months, he engineered dynamic 3D map integration using Angular, TypeScript, and CesiumJS, enabling terrain management, CRS-aware controls, and seamless 2D/3D synchronization. He improved admin workflows with multi-layer filtering, localization, and performance optimizations, while refining UI components for clarity and accessibility. Stein’s work included backend API integration, state management with NgRx, and rigorous unit testing, resulting in faster feature delivery, reduced configuration errors, and a scalable codebase that supports complex geospatial data visualization and editing.

Oct 1, 2025October 2025 monthly summary for Tailormap/tailormap-viewer: Delivered a set of high-impact improvements to the filter subsystem and UI, focused on accessibility, localization, and maintainability. Implemented a top-aligned filter UI with a reset button, improved button placement for better UX, and added a confirmation step for deleting filters. Enhanced localization with translations and Dutch text updates, and improved spatial and attribute filtering behavior. Consolidated filter state into core state to simplify development and reduce inconsistencies. Cleaned up code and strengthened type safety, while also improving test isolation and stability. Fixed critical merge issues in the filters module and protected non-configured filters from unintended changes, reducing risk of regressions in production.

Aug 1, 2025Month: 2025-08 — Key feature delivered: Filter Tool UI Enhancement in Tailormap/tailormap-viewer. Reordered the Preset filter option to the bottom of the admin core filter tool options and set the default to null (no tool selected). This improves user experience by providing a clearer initial state and more logical ordering. Implementation commit: 1b765b8adfb1cf36c42faaf1c2c9287738b2d6b9. No major bugs fixed in this module this month. Impact: smoother admin UI, faster command setups, and reduced misconfiguration. Technologies/skills: frontend UI/UX design, React/JS state management, commit hygiene, and repository discipline.

Apr 1, 2025April 2025 – Tailormap/tailormap-viewer: Key performance and stability improvements with significant feature refinements and refactors in on-demand loading, 3D rendering, and layer management. Business value achieved through faster startup, leaner runtime, and a clearer path for future enhancements. Key features delivered: - 3D and terrain rendering performance improvements and layer synchronization: implemented selective terrain updates, 3D layer re-render guards, simplified layer IDs, and ensured 3D view re-renders when 2D layers change to keep visuals in sync. This reduces rendering overhead and improves user-perceived performance. - On-demand Cesium.js loading and startup performance: Cesium.js is now loaded on demand and 3D map initialization is deferred until needed, cutting initial load times and resource usage. - CesiumManager enhancements: layer type handling and code quality: refactored CesiumManager to support terrain and 3D Tiles layers with clearer structure, improved error handling, and cleaned-up related functions; renamed create3dLayer to create3dTilesLayer for clarity. Major bugs fixed: - Eliminated unnecessary 3D re-renders by verifying layer changes before adding layers, reducing flicker and CPU usage. - Fixed terrain rendering triggers to update only when the terrain layer changes, improving stability and performance. - Addressed startup timing issues through on-demand Cesium.js loading and clarified CesiumManager error paths. Overall impact and accomplishments: - Faster startup and lower resource consumption due to on-demand loading; smoother 3D/2D synchronization and reduced rendering overhead. - More maintainable and scalable codebase with explicit layer-type handling and clearer function names, enabling faster delivery of future features. - Improved reliability of the visualization pipeline with targeted performance optimizations and robust error handling. Technologies/skills demonstrated: - CesiumJS 3D rendering optimization, on-demand module loading, performance profiling, and rendering synchronization. - Code refactoring for clarity and maintainability, including explicit layer-type handling and improved error handling.

Feb 1, 2025February 2025 (2025-02) monthly summary for Tailormap/tailormap-viewer. Delivered end-to-end 3D map capabilities with a robust Switch3D UX, EPSG:28992 compatibility, and improved 3D click processing. Implemented dynamic substitution of Web Mercator layers when switching to 3D, including layer-group substitutions. Revamped the Layer Selection UI from a checkbox to radio buttons to enforce mutual exclusivity and enhance UX. Improved code quality and stability through lint fixes and component deregistration cleanup, supported by enhanced test coverage and setup improvements. Technically, the work spanned Cesium/OpenLayers integration, 3D projection handling, 3D event management, and helper utilities for 3D protocol detection; it also involved maintaining and extending WebMercator layer substitutions and ensuring 3D readiness across multiple views.
