Worked on the geoadmin/web-mapviewer repository to address rendering fidelity issues with Cloud Optimized GeoTIFF (COG) layers in high-zoom scenarios. Focused on eliminating native-resolution interpolation artifacts by implementing a two-pronged fix that disabled interpolation for WebGLTileLayer and adjusted source-level settings in OpenLayersCOGTiffLayer.vue. This approach ensured that COG layers consistently rendered at their native resolution across WebGL backends, resulting in clearer map visuals and reducing artifact-related support requests. The work involved front end development using Vue.js and JavaScript, demonstrating attention to detail in resolving a nuanced rendering bug rather than introducing new features during the period.
