Just port of https://github.com/jiawlu/OSM2GMNS in Golang.

This tool allows to prepare routable graph of a given OSM road network with three levels of detalization:

1. Macroscopic + movements layer;

   • Images: W.I.P.
   • Data and fields description: W.I.P.

2. Mesoscopic;

   • Images: W.I.P.
   • Data and fields description: W.I.P.

3. Microscopic.

   • Images: W.I.P.
   • Data and fields description: W.I.P.

Stage: W.I.P.

• How to use as binary executable W.I.P.

• How to use as a package

  • Get latest version of the package

    go get github.com/LdDl/osm2gmns@latest 

  • Prepare *.osm (XML) or *.pbf (Protobuf) file with OSM data
  • Code:

    package main
    
    import (
        "fmt"
    
        "github.com/LdDl/go-gmns/generators"
        "github.com/LdDl/go-gmns/gmns/types"
        "github.com/LdDl/osm2gmns"
    )
    
    func main() {
        // Explicitly set global variables for logging (those are defaults actually)
        osm2gmns.VERBOSE = true
        osm2gmns.SUPPRESS_WARNINGS = false
    
        parser := osm2gmns.NewParser(
    	    "./sample.osm",
    	    osm2gmns.WithPreparePOI(false),
    	    osm2gmns.WithStrictMode(false),
    	    osm2gmns.WithVerbose(true),
    	    osm2gmns.WithAllowedAgentTypes(types.AGENT_TYPES_DEFAULT),
        )
        fmt.Println(parser)
    
        osmData, err := parser.ReadOSM()
        if err != nil {
    	    fmt.Println(err)
    	    return
        }
        macroNet, err := osm2gmns.GenerateMacroscopic(osmData, false)
        if err != nil {
    	    fmt.Println(err)
    	    return
        }
        fmt.Println("macro nodes num", len(macroNet.Nodes))
        fmt.Println("macro links num", len(macroNet.Links))
    
        movements, err := generators.GenerateMovements(macroNet)
        if err != nil {
    	    fmt.Println(err)
    	    return
        }
        fmt.Println("movements_num", len(movements))
    
        mesoNet, err := generators.GenerateMesoscopic(macroNet, movements)
        if err != nil {
    	    fmt.Println(err)
    	    return
        }
    
        fmt.Println("meso nodes num", len(mesoNet.Nodes))
        fmt.Println("meso links num", len(mesoNet.Links))
    }

• Test:

  # Load some OSM file to root of folder
  # Call this file sample.osm
  # Run:
  go test -timeout 30s -run '^TestParser$' ./*.go
  # After you will see some files in test_data folder
