Now available for download: New spatial selection options with the Advanced Selection bundle

Ralf Hackmann January 28, 2016

map.apps already offers standard functions to select features via the selection tool by dragging a rectangle (or circle, etc...) or by "drawing" multiple graphic shapes on the map, and displaying the seleciton results in the Result Center.

A new bundle, "Advanced Selection", now enables advanced spatial selection options, which may be quite complex in nature. Different selection methods are provided in a central selection widget. These are intuitive and optimized to be able to perform more complex selection methods with a few clicks, which till now may have required several operations.

Questions that can be answered quickly with the "Advanced Selection" Bundle include:

  • "Select all hospitals, which are within a radius of 5 km around a location (by clicking on the map)"
  • "Select all sections of road that are in a particular ring-zone of a location (by clicking on the map), or cut these"
  • "Select all branch locations that are within an area marked by clicking on the map sales area (zip-Region, Statistical County, State) ."
  • "Select all house connections that fall within an already-drawn object in the map view (eg planning area), which I select interactively by clicking on the graphical elements ..."
  • "Select all building areas based on a calculated travel time of 30 minutes from a location set by clicking on the map."
  • ...

The principle is always the same:

  1. In the first step you select from a list of the selection options; So the theme, from which the the objects are to be selected.
  2. The second step is to specify whether the objects completely inside a selection polygon (see Step 3) are to be included ("Include"), or whether the objects can also extend over the border of the selection polygon addition ("Touches")

  1. In the third step, different options are available to generate the selection polygon:
     
    1. Area
      You choose from a selection list, a theme that provides appropriate polygons/areas (for example, postal code areas, county boundaries, sales regions, planning areas, conservation areas, etc.), and by clicking on the map, a polygon is marked and a selection on the basis of this polygon is automatically executed.
    2. Freehand graphics
      You draw a freehand graphics; after completion of the graphic, the selection on the basis of this graphic is automatically executed.
    3. Predefined graphics
      By clicking on a graphic/drawn element already existing in the map, this is marked and a selection on the basis of this graphic is automatically carried out .
    4. Distance
      Using a slider, a circle or ring distance  is adjusted and the centre set by clicking on the map. The resulting circle or ring polygon is marked and used to automatically performed the selection.
    5. Drivetime
      Using a slider control, a driving time is set and then located by clicking on the map. The resulting drive-time polygon is marked and automatically used to carry out the selection (requires routing service!).

Das Bundle „Erweiterte Selektion“ ist über den map.apps Manager sehr einfach jeder App per Bundle-Upload hinzufügbar. Anschließend steht in der live-Konfiguration die vollständige Konfiguration zur Verfügung.

The Bundle "Advanced Selection" is easily added to the map.apps Manager uploading the available Bundle. Compete configuration is then possible via the live configuration.
