Our intelligent systems leverage groundbreaking advancements in artificial intelligence to convert high-resolution imagery of our earth into HD vector maps. Leveraging AT-processed raw images, Ecopia compiles stereo aerial images in a 3D environment. The imagery is then processed through proprietary extraction and modelling software, hosted in a secure cloud environment, and then post-processed and Quality Controlled before delivery. The final deliverable is a comprehensive and accurate vector map. <\/SPAN><\/P> <\/P> Measure Name Threshold Across Impervious Polygons<\/SPAN><\/P> False Negatives <=5% All Polygons<\/SPAN><\/P> False Positives <=5% All Polygons<\/SPAN><\/P> Valid Interpretation >=95% All Polygons<\/SPAN><\/P> Minimum Area 100% All Polygons<\/SPAN><\/P> Valid Geometry 100% All Polygons<\/SPAN><\/P> <\/P> Measure Name Threshold Across Natural Polygons<\/SPAN><\/P> False Negatives <=5% All Polygons<\/SPAN><\/P> False Positives <=5% All Polygons<\/SPAN><\/P> Valid Interpretation >=90% All Polygons<\/SPAN><\/P> Minimum Area 100% All Polygons<\/SPAN><\/P> Valid Geometry 100% All Polygons<\/SPAN><\/P> <\/P> Landcover Details and Minimum Mapping Units:<\/SPAN><\/P> 1.
