North Property Line measures 3925.405' when in fact the survey indicates it is <br />3898.68'. <br />B. South Property Line measures 3189.69' when in fact the text on the line is 3164.95'. <br />Drawing ZC-4G <br />When the drawing is scaled so that the north property line (A) measures the same as the <br />survey text (3898.68) then the south property line (B) and the bar scale are not accurate. <br />Graphic Scale: I"= 198.44' <br />A. North Property Line measures 3898. 68' and the survey indicates it is 3898.68'. <br />B. South Property Line measures 3167.78' and the text on the line is 3164.95'. <br />Maps are only as good as the data used and the accuracy with which they can be assembled (or <br />not). <br />Sheet LHVC 912115-04 also contains inaccuracies because of the nature of the medium used to <br />assemble the maps. It is not that LHVC intentionally created maps that were inherently <br />inaccurate. There are simply limitations to accuracy based on limitations of the data used. <br />There is nothing more accurate than having original vector data (mathematical calculations from <br />one point to another creating a line) vs. raster (images made up of pixels as contained in Bit <br />Maps, PDFs, JPEGs and paint programs). <br />Vector graphics are resolution independent. Here is a picture that explains their accuracy better <br />The 4 plans submitted by the applicant at the public hearing on 9.21.16 (ZC-4A, ZC-4B, ZC-4C <br />and ZC-4D) are examples of plans that used a raster image for the Metro Plan (the official <br />adopted plan is on paper and therefore could only be a raster image) merged with the surveyed <br />referents (ACAD vector data). <br />It is the most accurate method of merging the Metro Plan with the surveyed referents. <br />Schirmer Satre Group . 375 West 41" Avenue, Suite 201, Eugene, OR 97401 • (541) 686-4540 <br />
