When I blogged about the official end of zigGIS last week, I included a mention of PgMap, a free extension to ArcMap for direct read/edit of PostGIS data. Judging from outbound links, there seems to be a good bit of interest in it so I decided to take a look.
To recap, Abe decided to pull the plug on zigGIS due to the fact that ESRI will support direct read/edit of spatial databases (as simple features) in 10.1. In my opinion, this is a good development. With native support coming, there was no need to continue with zigGIS. That support, however, will only exist in ArcGIS 10.1. Users of older versions will need to find alternatives. Based on our experience with zigGIS (as well as download data I’ve seen for the WeoGeo toolbar), there are a lot of people (especially outside the US) still using ArcGIS 9.x so demand for an alternative will probably be high for some time.
