Colour postcodes inside travel areas

Turn your travel areas into coloured postcode territories with one button. The matching areas take the coverage colours and appear in your normal map key. There is no list to find, copy or import first.

1. 1

   Set up your coverage

   Choose the starting point you want to use and press Create or Update on map first. Only that starting point’s calculated travel bands are used. Check the position, sizes, colours and labels before colouring. Hiding the coverage does not remove it from this calculation.

2. 2

   Colour postcodes

   Click Colour postcodes. On an uncoloured map the result appears straight away. On a map with existing territory colours you choose what to keep. This uses the shapes already on your map; it does not make another travel-service request.

3. 3

   Add to existing

   Keeps every postcode that already belongs to a coloured territory, even where the new coverage overlaps it. Only uncoloured matching postcodes receive the new colours. Your existing key entries and notes stay in place.

4. 4

   Replace colouring

   Clears all existing territory colouring and its key entries, then colours only the matching postcodes. Areas outside the coverage become unassigned. Your circles, dots, travel areas, images, text and other map artwork stay in place. Cancel or the close button leaves everything unchanged.

5. 5

   What counts as inside?

   The tool tests the representative centre of each polygon at your map’s postcode level. It colours the whole area, district or sector when that centre falls inside the coverage. A polygon may extend beyond the edge, or partly overlap the coverage without being selected. This is not a list of individual addresses or an exact clipped boundary.

6. 6

   Colours, labels and overlaps

   Travel band colours and labels become the territory colours and key names, prefixed by the starting-point name. Where bands overlap, the inner band wins.

7. 7

   Undo, save and refresh the result

   Undo reverses the whole colouring operation in one step; Redo restores it. Save keeps the new territory colours and key. Colouring is a snapshot: moving coverage or changing its labels later does not recolour the territories automatically. Click Colour postcodes again and choose Replace colouring to rebuild just this coverage, or Add to existing to fill only uncoloured gaps.
