Point: A point form allows you to drop a point on a map which creates a feature/data point on the map. Creating new forms for the location of new potholes in your city or the location of animal sightings in your area are examples of use cases of a point form.
Polygon: A polygon form allows you to draw a polygon on a map which created a new feature/data area on a map. This is useful for when you want to draw the area to represent a plot of land, building, or area on a map.
Line: A line form allows you to draw a line on a map that creates a new feature/data on a map. When you would like to track a line or distance on a map, a line form would be useful in representing that. Examples of a line form would be when you want to show on a map how long a sandbag barrier is to prevent flooding.
Repeatable Section: Repeatable forms are a type of form that doesn't have it's own geometry, but can be nested within forms that do have geometries or used on it's own. Repeatable Sections allow users to create a set of form questions that can be repeated an infinite amount of times within the form that is being filled out. An example of when a repeatable form might be used is in housing inspection forms. In a section where it asks how many appliances the house has, there might be multiple types and amounts of appliances, so inside the form you can add as many entries as necessary that apply to that situation.
Data Form: Data forms allow you to input data into Lightship without having it's own geometry. An example of a data form would be if you want to keep track of your clients information (name, address, phone number etc.) through Lightship.
Form Linked to an Existing Layer: A linked form contains tabular data that has no geometry, but is instead associated, or linked, to a layer with geometry. One use case for linked tables is inspections and maintenance on assets. For example, you can create a linked form for your inspections data and attach it to a unique ID for each individual asset in the dataset. This enables you to attach inspections to assets without altering the original data.
