1. To locate the tool most easily, just search for ‘feature class to feature class’. Select the tool that is highlighted in the image below.
2. Select the shapefile that contains the 3D features, and load it into the ‘Input Features’ dropdown box. Enter the ‘save’ location for the new shapefile.
3. Select the ‘Environments…’ button to access the ‘Z Values’ settings. This is where you will disable the z-value of your shapefile to create a 2D shape (see the two images following). Repeat for ‘M Values‘.
4. Click ‘OK’ and you are ready to load your new 2D shapefile into iGIS.

Some users have reported discrepancies with the location of their data over the basemap imagery in iGIS and/or a desktop GIS tool (such as ArcMap). If you are noticing a shift in your layers, this article may help you.
All vector data in iGIS is stored in the common coordinate system: WGS84 EPSG:4326. All raster data in iGIS (pre-processed through MapTiler software) is stored in the common coordinate system: EPSG:900913. Using these coordinate systems for all source data speeds up rendering in iGIS’s map display.
iGIS uses the open source proj4 library ( http://trac.osgeo.org/proj/ ) to support:
the reprojection of vector data on import/export from its original defined input coordinate system to WGS 84 (EPSG:4326)
re-projection of displayed iGIS project map centre coordinates from the WGS84 coordinate system into the projection defined for a particular project.
If you are unsure which coordinate system to use when you create a new project, we recommend you use the default EPSG:4326 WGS84 Lat/Lon for vector data. This will ensure your data collection is not affected by reprojection within the application.
If you find that your points don’t line up with your basemap imagery as expected, it is likely that there is a bug with the proj4 library. Bugs in the library can be submitted at the Proj4 website http://trac.osgeo.org/proj/ We incrementally update iGIS’s version of the Proj4 library with the latest available version, so when a fix becomes available in the library it will make its way into iGIS. Until then, the only workaround is to transform your data into a supported coordinate system, i.e. EPSG 4326 – WGS 84, with third party software like ArcGIS, prior to iGIS import.
UPDATE 2: This guide was updated in July 2017 to include instructions for iFunbox. The old instructions for iPhone Explorer/iExplorer may be outdated.
UPDATE: The pro version of iGIS is now able to export projects via the Data manager. At this stage, it will not export imagery layers.
If you need to restore your iPhone or iPad, or you wish to transfer your projects to a new phone, it is possible to save your projects and settings in their current state.
iGIS uses two sqlite databases in its backend; spatial-store.sqlite and Projects.sqlite. In most cases data can be restored to your iPhone after from these files using free third party software as described in the steps below.
Get a copy of these backend database files off your device using third party software like iPhone Explorer or iFunbox. The development team uses iFunbox.
Method 1: Using iFunbox
Download and install iFunbox on your computer. The development team uses version 1.8 on Mac. At the time of writing, this version was working with all iOS devices.
Connect your iOS device via USB to the computer you installed iFunbox on.
When you launch iFunbox, you should see something like the screenshot below.
Click on “App File Sharing” or the left arrow to expand the folder. In here, you should see folders for all the applications on your iPad that support file transfer. Go into the folder for the version of iGIS you are using (iGID HD for iPad, iGIS for iPhone).
Inside this folder, you may see a number of blue folder icons. For the purpose of restoring projects, you need to go into the .database folder.
Inside the .database folder, there will be two database files. spatial-store.sqlite stores the layer data and features. Projects.sqlite stores the information about what projects you have and what is in each project.
Copy both of these files to your computer by selecting them and right clicking. You should see an option to copy these files to your Mac or PC. You can also drag and drop them from iFunbox.
If you want to have a look at what is in these files, you can use an SQLite browser. The development team uses SQLite Manager for Firefox.
Replace these two files if you want to restore your projects from another device. Simply copy the version of the files that you want, which overrides the old version. You can drag and drop into iFunbox to do this. Do not use iGIS at the same time you are replacing files.
When you restart iGIS, it will read the new files instead and your projects and layer data will be the replaced version.
Method 2: Using iPhone Explorer/iExplore (old guide)
Device 1 (or, prior to restoring your device)
Using iExplore, with your iPhone/iPad connected to your computer, navigate to: <*Your Device Name*>\Apps\iGIS\Documents\
Copy the ‘.database’ folder to your desktop.
Note: You can simply copy the entire ‘Documents’ folder if you would prefer.
Disconnect your device.
2. Device 2 (or, after restoring your device)
Install iGIS and run once.
Quit the app (iOS7: double tap the home button and flick the app window away; iOS6: double tap home button, hold iGIS icon, then remove with red button).
Connect your device to your computer and open iExplorer. Navigate to the same folder as before: <*Your Device Name*>\Apps\iGIS\Documents\
Overwrite the existing folder with the folder that you saved to your desktop.
