Digitizer

The Digitizer element allows building editing-interfaces. Currently you can build up your interface for point, line and point editing with a YAML-definition. Right now PostgreSQL is supported as a database. Oracle and SpatialLize can be used experimentally. The development of the data-sources allow other data sources so that it can be extended to support - for example - OGC WFS services.

The Digitizer-Element offers complex editing functionality:

  • move objects
  • add vertices (lines, polygons)
  • generation of enclaves, exclaves, circles and ellipses

You can define very complex formss for the attributes. This follows the capabilities of Mapbender 2.x.

../../../../../_images/digitizer1.png

The following option for the construction of the forms are available:

  • define more then one feature types for digitalisation. You can switch from one feature type to the other with a select box
  • use a table as source. You can also define a filter to get a subset of the table
  • Textfields
  • Selectboxes, Multiselectboxes
  • Radiobuttons, Checkboxes
  • Textareas
  • Datepicker
  • File upload
  • Definition of tabs
  • Definition breaklines
  • Definition of Text
  • Mandatory fields, regular expressions to valida the content are possible
  • Help textes

Configuration

../../../../../_images/digitizer_configuration1.png

You can use the element in the sidepane or as a dialog with a button.

The Ditigitzer needs access to a database where the editable tables are. You have to define a new database configuration to be able to connect with the geo database. Read more about this at http://doc.mapbender3.org/en/book/database.html

The definition of the digitizer is done in YAML syntax in the textarea configuration at schemes. Here you define the database connection, the editable table, the form to display the table, the attribute form and other behaviour.

Definition of the feature table

The Digitizer provides a feature table to navigate to features and select features for editing. The columns are sortable by default. You can define width (% or px) for each column.

  • tableFields - define the columns for the feature table.

  • all - lists all features in the table
  • currentExtent - list only the features displayed in the current extent in the table (default)
