Maps
Route map
Shows actual or planned paths through geographic space.
- Map
- Geography
- Navigation
What it answers
Where does a route go?
- Shape
- Ordered geographic paths
- What it shows
- Path, stops and geographic detours.
Example
The question
Which route does today’s delivery van take?
Delivery route for van 3, 12 March (route map)
Illustrative data. It belongs to no company.
When to use it
Use it when
Actual or planned travel/navigation paths.
Avoid it when
When unordered coordinates are connected as if they were a route.
How to read it
Follow the ordered line and direction markers on a geographic base.
Note
Supply point order or complete line geometry.
The data you need
- Layout
- Ordered vertices or line geometry
- Fields
- RouteID: text; Sequence: integer; Longitude,Latitude: numbers
- One row is
- One ordered vertex along a route. What is the grain?
- Rules
- Sort vertices within each route and use a stated CRS. Coordinates alone do not establish a road-following route.
- Optional
- Alternative LineString geometry; optional Timestamp for movement.
- Preparation
- Validate the input grain and missing values. Sort vertices within each route and use a stated CRS. Coordinates alone do not establish a road-following route.
- Units
- State the mapped attribute unit, geographic level and boundary/coordinate reference. Rates need an explicit population or area denominator.
Worked example
RouteR1 has ordered vertices(18.00,59.30),(18.05,59.32),(18.07,59.33). Join in sequence; these vertices alone do not prove a road-following route.
| RouteID | Sequence | Longitude | Latitude |
|---|---|---|---|
| R1 | 1 | 18.00 | 59.30 |
| R1 | 2 | 18.05 | 59.32 |
| R1 | 3 | 18.07 | 59.33 |
