Custom data entry forms

The following article will document the process for generating and editing custom .glc files in order to create custom data entry forms in iGIS.

You can import: a .glc with your shapefile; and export it from iGIS.


To start using customized forms, we recommend that you follow the following steps:

  • Step 1. Download the below linked sample glc shapefile data and become familiar with the format by; investigating the file in a text editor, importing it into iGIS, editing the shapefile in iGIS.
  • Step 2. Export your shapefile layer from iGIS to automatically create the *.glc.
  • Step 3. Edit your iGIS created *.glc template file with a text editor to add lookup code lists. Use the sample *.glc file from step 1 as a syntax reference.
  • Step 4. Import your shapefile into iGIS with your *.glc file, and begin editing your data with codelists.
