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 STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN>Measure Name Threshold Across Impervious Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>False Negatives <=5% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>False Positives <=5% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>Valid Interpretation >=95% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>Minimum Area 100% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>Valid Geometry 100% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN>Measure Name Threshold Across Natural Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>False Negatives <=5% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>False Positives <=5% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>Valid Interpretation >=90% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>Minimum Area 100% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>Valid Geometry 100% All Polygons</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN>Landcover Details and Minimum Mapping Units:</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>1.
