How do I create a .zip file?

iGIS currently uses .zip files to import and export data.

A zip file  is a compressed folder that saves on space, allowing faster transfers. A zip can be created naturally on modern desktop operating system.  Usually this is done by selecting the items you want to zip, right clicking on them and selecting the option along the lines of “compress” or “send to>compressed (zipped) folder”.


For iGIS to use spatial data, the .dbf, .shp and .shx must not be contained in a subfolder within the zip.

Clashing .glc files?

If you have had trouble with your projects using the wrong .glc files, it may be because you have CodeLists that are repeated across multiple .glc files.

It is necessary to ensure all names in the CodeList are unique.

For example, if you have two projects with unique .glc files, that contain the ‘same’ CodeLists (with unique values).

In this case, the .glc will associate with the wrong projects.

To remedy, provide each CodeList name with a unique identifier.



Retrieving data from iGIS

If you need to recover the data stored in iGIS you can retrieve it from your iPhone or iPad.

iGIS uses two sqlite databases; spatial-store.sqlite and Projects.sqlite. If you retrieve these files they can be used as a permanent backup or sent to Geometry for fault finding purposes.

Get these database files off your device using third party software like iFunBox

Using iFunBox, with your iPhone/iPad connected to your computer, open iTunes File Sharing:

Select iGIS (or iGIS HD) and select Open Sandbox


Select the .database directory and copy both the Projects.sqlite and spatial-store.sqlite to your PC


What field types are supported for iGIS *.glc files?

When the iGIS WiFi import page tool is used to create a *.glc file for shapefile data, each field will be described as one of the below types;






iGIS also supports a number of special field types which can be used to replace these default types. When special types are defined the application will auto populate values on feature creation/edit.

iGIS Features

UPDATE: This article has been updated to reflect new features as of 24-6-16.

True GIS functionality is finally available for the iPad or iPhone! Your data, your maps, your device. Overlaid on satellite and map imagery, you can now import your spatial data and view it wherever you are.

Importing data into iGIS is easy. You can import spatial data using Dropbox, email or via USB on iTunes. Only ESRI Shapefiles (.shp) are supported at the moment.

Your spatial data is stored on the iPad, so there’s no need for an Internet connection to see your data – great for field work. We also support over 3000 projections, so no need for conversion.

We include support for multiple layers or points, lines or polygons – all styled as you like.

You can edit your data also – points, lines and polygons can be added. Track the GPS , use it to set waypoints or touch the screen – there are may ways to capture spatial data with iGIS.

Once you’ve collected the spatial data, you can add attributes in a data entry form. Even better, you can set the format of this form to suit your needs. Code lists, time stamps auto increment fields, default values, field ordering, feild hiding, etc, are supported. All data can be exported as an ESRI shapefile for your use back in your enterprise.

Look at the list of features:

  1. Unique menu system, with map icons – set your own icon from the map!
  2. Create lines, polygons and points
  3. Advanced editing on shape features, even once they have been saved
  4. Use inbuilt GPS for tracking logs and waypoints.
  5. Data entry forms can be customized with code lists, timestamps, etc.
  6. Import and export using ESRI Shapefiles
  7. Shows current GPS location on iPad + compass.
  8. Zoom to current location or data extent
  9. Pan, zoom in, zoom out on maps
  10. Changeable drawing styles for a layer: size, color, transparency
  11. Can arrange layer order and turn layers on/off easily
  12. Can set when a layer is shown using sliders
  13. Select and interrogate layer information via a point and click
  14. Shows the selected data on the map
  15. Show current coordinate in any chosen projection

This application is designed for GIS professionals and an understanding of some basic GIS concepts such as layers, shapefiles, projections etc, would make using iGIS simpler. Please let us know if concepts in iGIS are unclear.

Please let us know what features you’d like to see added or improved.
