Hi, I would like to interpolate irregularly placed points representing the height of a surface (actually it is a geological surface underground, but the same should apply to terrain). However, my point data comes from 2 different sources that do not have the same confidence levels. - The first group are more or less exact measurements of the height of this surface (in boreholes) having a very low error level. Hence, my calculated surface should honor these points more or less exactly. - The second group of points comes from estimations and have significantly higher and variable error levels (increasing with depth actually). Of cours, points of this group would not have to be honored as precisely. In the interpolation process, I would like to give a different weight to these 2 groups of points. How would I do this? Thank you for any helpful suggestions, Robert ... View more

Hi, The new function for direct import of geotagged photos in ArcGIS Explorer Desktop seems really nice, but I ran into an accuracy problem while using it for the first time: I imported several photos with GPS coordinates in the EXIF data from a GPS Camera. All photos are taken right on the edge of a highway. The thumbnails show up without error, but are placed at nearly 500 meters (to the SW) from the point they were taken. Same with other photos. (Do test this further, I opened Google Earth from my Picture Viewer Program and the dot showed up in the rightplace. When I exported these Google Earth 'temporary locations' to a kmz file and import the latter into ArcGIS Exlporer, the point is in the right place this time. ) I attach one example photo and would be happy if someone could try to reproduce this error or tell me what could have gone wrong in my case. Thanks for any help or suggestions, Roby Attached: 11-08-26-A13-21_r.JPG (geotagged photo) and 11-08-26-A13-21.zip, (containing the corresponding knz file exported from Google Earth) ... View more
