I have extracted EGM2008 1x1 degree grid geoid for Peru. This can be used instead of EGM96 with higher accuracy. Just extract it and copy as egm08_25.gtx file to Contextcapture\data\gdal and you will have now it as option from vertical coordinate system override. communities.bentley.com/.../4540.egm2008peru.gtx.zip
