Yeah, that’s not news to a lot of you, but it is to me. My last significant exposure to ESRI’s ArcGIS Explorer digital globe software (Windows only) was back when it came out, quite a few years ago. I tried it, and found it inferior to Google Earth in performance in 3D, and too complicated to bother learning it, since then, I’ve stuck strictly with Google Earth. A recent post on the free Garmin Tool application, which creates Garmin Custom Map overlays using ArcGIS Explorer, forced me to look at it again, and I was surprised to discover that it’s turned into a pretty cool, and pretty useful tool. Not perfect – the 3D performance is still pretty weak compared to Google Earth, and the out-of-the-box configuration isn’t as strong. But it has it’s own very strong set of features, and when used in 2D mode, is a good addition to any geography toolbox. Nice re-organization of tools/features in a MS-Word-like ribbon format, much better than the original interface. What date was this published? Or another way, what version of AGX are you commenting on? I think Build 1500 is the current version. I’ve had mixed success with AGX so far: in theory it’s great but seems to crash a lot on a lot of different computers we have here, especially when trying to utilize layer files pointing to geoDBs in SDE. I’m using Build 1500 as well, haven’t seen the problems you’ve had, though I haven’t connected to geoDBs. Source.
