Geographic data

Geographic data can be of different type: a point (single location) or a polygon (area). This field captures such geometric features in GeoSON format. It is possible to capture multiple geographic data (of the same type).

Preview

Some controls are available on the map:

• the +/- buttons to zoom in/out,

• the fullscreen button,

• the trash icon to delete all the selections,

• the target icon to center the map.

Single location selection on the map.

Multiple locations selection on the map.

Selection of an area on the map.

Example of geographic data (a point in GeoJSON format):

{
   "type": "Feature",
   "geometry": {
     "type": "Point",
     "coordinates": [
       -74.18465727715618,
       46.03587230951427
     ]
   },
   "properties": null
}

Design

Definition

The standard properties apply:

Property	Definition
Type	The type of item (see above).
Name	The name of the item is not visible. It is a “variable” name that will be associated to the data collected. You will refer to this variable name when writing condition and/or validation scripts.
Label	The label is usually a question or a title.
Description	The description gives some guidance about how to enter data, what are their meaning etc.
Required	Whether an input is mandatory. Note that this does not apply when the visibility Condition is not satisfied.

The following dynamic properties apply:

Property	Definition
Condition	The condition makes an item visible or not, depending of other data. It is a small script which returns a logical value: true when item is visible. When no condition is specified (which is the default), the item is visible. See How to make fields conditional?
Validation	The validation specifies whether the data entry is correct. It is a small script which returns a logical value: true when item value is valid. Note that this validation script is not evaluated when the visibility Condition is not satisfied. See How to validate field values?
Validation error message	The validation error message to be displayed when validation fails.

Settings

Property	Definition
Default	The default value. When Multiple choices is set, an array of GeoJSON objects is expected, otherwise a single GeoJSON can be provided.
Geometery type	As per the GeoJSON standard: Point or Polygon.
Map center	Position of the center of the map, using format: [longitude,latitude]. Default is [0,0]. When clicking on the target icon, the map will be repositioned at that location. If the geo location is activated, the starting point will be the map center, then the current position as reported by the device will be used.
Zoom	Zoom to apply when the map center is defined.
With geo location	The device will report the current position (usually a combination of positions from GPS, mobile network, internet entry point).
Multiple choices	When selected, the captured data is a list of geometric features. Default is false, i.e. a single value is captured.

Style

Property	Definition
Label class	CSS class to apply to the field label. See How to style a form item?
