|
|
|
|
|
|
**Routing queries using the ORS plugin**
|
|
|
|
- Add a background layer into your QGIS project:
|
|
|
|
- Under the „web“ tab, choose „Open Layers Plugin“
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- The queries can now be run with using the layer as a spatial reference.
|
|
|
|
|
|
|
|
**Isochrones- Accessibility/ Reachability Analyses: How far can I go in a specific time/ within a specifc distance?**
|
|
|
|
|
|
|
|
- open the „Batch Jobs“ menu
|
|
|
|
- Choose „Isochrones from Point“ if you would like to create an isochrone around a certain location on the map canvas in your QGIS project
|
|
|
|
- Mark your input point/location using the background layer
|
|
|
|
- Dimension: Choose „time“ or „duration“ as dimensions
|
|
|
|
- Comma seperated ranges: Choose the preferred intervals (if multiple seperate using a comma sign)
|
|
|
|
- As output, choose location where the output file should be stored on your computer
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- „Run“ the query
|
|
|
|
- The output file will appear as an extra layer, the attributes and, thus, chosen parameters can be checked in the attribute table
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- Choose „Isochrones from a layer“ if you would like to create isochones around points in a already existing layer
|
|
|
|
- Choose your input layer (or points within the layer using „selected features only“)
|
|
|
|
- Dimension: Choose „time“ or „duration“ as dimensions
|
|
|
|
- Comma seperated ranges: Choose the preferred intervals (if multiple seperate using a comma sign)
|
|
|
|
- As output, choose location where the output file should be stored on your computer
|
|
|
|
- „Run“ the query
|
|
|
|
- The output file will appear as an extra layer, the attributes and, thus, chosen parameters can be checked in the attribute table
|
|
|
|
|
|
|
|
**Matrix: Calculation of distances/ travel duration between input points (in one or two input layers)**
|
|
|
|
|
|
|
|
- Choose „Matrix“ in „Batch Jobs“
|
|
|
|
- Choose an „Input Start Point Layer“ and an „Input End Point Layer“ (can also be the same if you would like to calculate the distance/travel time between points within a single layer)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- Choose the „Travel mode“ in the dropdown menu
|
|
|
|
- „Run“ the query
|
|
|
|
- The result is a table providing information about the time/ travel distance between the points within a layer/ in two layers
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
**Fastest and shortest route**
|
|
|
|
|
|
|
|
- If you want to create a route based on points that you create in your QGIS project:
|
|
|
|
Advanced directions:
|
|
|
|
Go with:
|
|
|
|
- Choose your preferred mode of travel
|
|
|
|
- And choose between „fastest“ and „shorest“ route
|
|
|
|
- Click on „+“ sign to select points on the background layer
|
|
|
|
- Left click to add a point, double-click to finish
|
|
|
|
- When you added all points, click on „Apply“ on the bottom oft he window to run the routing query
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Optional:
|
|
|
|
- Advanced settings:
|
|
|
|
- Travelling salesman: Optimal route changing the order oft he given routepoints
|
|
|
|
- Avoid tags: Avoid certain road types
|
|
|
|
- Avoid countries: Potentially of relevance when creating international routes
|
|
|
|
- Avoid polygons: You can avoid specific areas. These can be provided in another layer in your QGIS project (load external data or draw the area to be avoided yourself)
|
|
|
|
|
|
|
|
- If you already have locations that you would like to run a route query for: Choose „Batch Jobs“
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- Choose the input according to your input layer (point or line)
|
|
|
|
- Choose your input file
|
|
|
|
- Like in „Advanced routing“, choose your preferred travel mode, shortest or fastest route and if the route should be optimized (travelling salesman)
|
|
|
|
- As output, choose location where the output file should be stored on your computer
|
|
|
|
- „Run“ the query
|
|
|
|
- The output file will appear as an extra layer, the attributes and, thus, chosen parameters can be checked in the attribute table
