Wepi now includes a geolocation variable and a statistics tab.
The left side shows the count for missing values and the right side shows the basic "code book" information for each variable. You can filter either by anonymous guest or by the invited surveyor.
The GPS variable is either the type of question, "Where did the event take place?" (left) which allows the person filling in the questionnaire to place a pin on a map. Or one can use the GPS variable for "Where are you now?" type questions (right) which, when used on a smartphone or tablet, gets the position of the person through the GPS on-board hardware.
