I'm starting to develop an application for iPad which should enable the users to go to the field and acquire georeferenced information. The idea is to enable acquisition of points and polygons, and the filling of a set of attributes for the geometry. Also important is the ability to connect to externals geo-referenced databases, such as a PostGIS one.

Ideally, I would want to be somewhat similar to the ArcGis for iOS application, which has a good user interface.

Can you guys point me to other applications similar to what I am developing? I already know the following ones:

  • Geo-jot
  • pcMapper
  • iGIS
  • GISRoam
  • field_assets
  • Geopaparazzi

Possibly you can point me to something with similar functionality to the ArcGis for iOS?

OR

Interesting programming frameworks to achieve the desired functionality on iOS?

ExtMap and iExtMap may meet this requirement.

iExtMap is a mobile GIS Viewer for iOS. (for IPhone, IPod and IPad) It is different than ExtMap Web because Ext JS (or Sencha) is not used in this project, but the same name "ExtMap" is used for familarity.

iExtMap is developed as native application for iOS devices and it can be available at App Store for free. iExtMap is a hybrid application that uses both native and web features of iOS. All the forms and structure are built on iOS platform and mapping part is based on Google Maps API v3.

iExtMap is simple a GIS Viewer for iOS so that there is no identify or query features like in ExtMap Web. It shows the ArcGIS Server Services, WMS, KML/GeoRSS and Static Tile Services on Google Maps base maps with bookmarking and geolocation features.

However, as pointed out in the comments there has only been one version released, and that was in 2010, but it is still available from the Apple Store.

That app appears to be basically dead. 1.0 release in 2010, and no updates since then. – Jesse Crocker Aug 26 '14 at 23:04

I like GISKit from Garafa, though it too seems to have been forgotten about for a while. the developers have updated it over time, but it seems its festure set has not expanded and longstanding bugs still stand.

That said they did a good job with the interface and I find it very intuitive. I wish it were not an extra $200 just to get access to SHP files and be able to share projects between tablets though.

However, they do support building picklists and customized symbology, the map renders very fast with smooth navigation, offline caching is available too, and recently they added some feature server connectability.

Still, any time I've emailed them in the last 2 years asking about longstanding bugs or if the app's features are going anywhere new, I don't get a lot of positive feedback from the developer's replies. They had a huge headstart on other GIS apps on tablets, but seem to have lost the lead. Still, worth checking out.
