ESRI's viewer isn't scammy or malware-infested. I don't use it much but when I do it's as a third source. Layers include their own topo maps, street maps, and aerials, plus OSM and Bing products.jondrush wrote:Yes, I'm trying to avoid third party vendors or viewers so we don't run afoul of any licensing issues. I know there are free GIS data viewers out there, but the one's I've looked at seem scammy or malware-like.
In case anyone feels reluctant to use this private company's viewer, the list identifies the states who use it. IANAL, but since these states license it for public use, I don't think there's an issue. Here's the disclaimer from Mississippi's viewer:
