A work in progress that is well worth the money – iGIS Review

For anyone who has GIS data they would like to display on an iphone this is the app. Their data upload is very slick. Initially I had difficulty getting the projection that we use at work to execute, but the support was very responsive and I was able to get it going in short order. For those who use WGS84, you will have no difficulties. Since I bought it there have been several good updates and the developers seem to be actively upgrading the app. Hopefully they will continue to add more options for symbology and labeling. Some of the earlier comments indicate difficulty with exported shapefiles and the like. I too ran into a problem with one shapefile, but I sent it to the developer and they found the problem and updated the app. (FYI: I work on a water distribution system and the program easily handled 14 different point and line shapefile sets, each with 1,000 to 6,000 features (I did use zoom levels to help with performance.))
