I currently import a kmz file created in ArcMap 9 (via a very convoluted process using Google Earth) to my Garmin Oregon GPS. I do this so that I can view an aerial photo with town tax parcel map info and other specific features on my GPS. Due to a recent upgrade to Google Earth I can no longer use it on my (very old) computer. We plan to upgrade to ArcMap 10 in the not-too-distant future, and I'm wondering if this will solve my problem, or if I need to purchase a new computer. Does anyone know whether I'll be able to do this with ArcMap 10 and the Garmin Oregon GPS? Pointers to instructions would be much appreciated!
More about why I do this, and how: I work for a land trust, and often need to find boundaries on individual parcels of land. I sometimes can find either a shape file for the parcels or find the parcel information on Google Earth, but not often, so I go into ArcMap and create a .jpg, then go into Google Earth and add the .jpg as an image overlay. I then find the coordinates of the corners of the .jpg in ArcMap, add these to Google Earth, then click on Save Place As to create a .kmz file which I can move over to my Garmin Oregon device. It's cumbersome but it works (or did, until Google Earth stopped working on my computer!).
