GISManager

Publish Your GIS Data(Vector Data) to PostGIS and Geoserver

How to install:
- go get -v github.com/hishamkaram/gismanager

Usage:

testdata folder content:

./testdata/
├── neighborhood_names_gis.geojson
├── nested
│   └── nyc_wi-fi_hotspot_locations.geojson
├── sample.gpkg

create ManagerConfig instance:

manager:= gismanager.ManagerConfig{
  Geoserver: gismanager.GeoserverConfig{WorkspaceName: "golang", Username: "admin", Password: "geoserver", ServerURL: "http://localhost:8080/geoserver"},
  Datastore: gismanager.DatastoreConfig{Host: "localhost", Port: 5432, DBName: "gis", DBUser: "golang", DBPass: "golang", Name: "gismanager_data"},
  Source:    gismanager.SourceConfig{Path: "./testdata"},
  logger:    gismanager.GetLogger(),
}

get Supported GIS Files:

files, _ := gismanager.GetGISFiles(manager.Source.Path)
for _, file := range files {
  fmt.Println(file)
}

output:

<full_path>/testdata/neighborhood_names_gis.geojson
<full_path>/testdata/nested/nyc_wi-fi_hotspot_locations.geojson
<full_path>/testdata/sample.gpkg

read files and get layers Schema:

  for _, file := range files {
    source, ok := manager.OpenSource(file, 0)
    if ok {
      for index := 0; index < source.LayerCount(); index++ {
        layer := source.LayerByIndex(index)
        gLayer := gismanager.GdalLayer{
          Layer: &layer,
        }
        fmt.Println(layer.Name())
        for _, f := range gLayer.GetLayerSchema() {
          fmt.Printf("\n%+v\n", *f)
        }
      }
    }
  }

output sample:

neighborhood_names_gis

{Name:geom Type:POINT}

{Name:stacked Type:String}

{Name:name Type:String}

{Name:annoline1 Type:String}

{Name:annoline3 Type:String}

{Name:objectid Type:String}

{Name:annoangle Type:String}

{Name:annoline2 Type:String}

{Name:borough Type:String}
...

add your gis data to your database:

  for _, file := range files {
      source, ok := manager.OpenSource(file, 0)
      targetSource, targetOK := manager.OpenSource(manager.Datastore.BuildConnectionString(), 1)
      if ok && targetOK {
        for index := 0; index < source.LayerCount(); index++ {
          layer := source.LayerByIndex(index)
          gLayer := gismanager.GdalLayer{
            Layer: &layer,
          }
          newLayer, postgisErr := gLayer.LayerToPostgis(targetSource, manager, true)
          if postgisErr != nil {
            panic(postgisErr)
          }
          logger.Infof("Layer: %s added to you database", newLayer.Name())
        }
      }
  }

output:

INFO[14-10-2018 17:28:37] Layer: neighborhood_names_gis added to you database 
INFO[14-10-2018 17:28:38] Layer: nyc_wi_fi_hotspot_locations added to you database 
INFO[14-10-2018 17:28:38] Layer: hwy_patrol added to you database

update the previous code to publish your postgis layers to geoserver

 for _, file := range files {
   source, ok := manager.OpenSource(file, 0)
   targetSource, targetOK := manager.OpenSource(manager.Datastore.BuildConnectionString(), 1)
   if ok && targetOK {
     for index := 0; index < source.LayerCount(); index++ {
       layer := source.LayerByIndex(index)
       gLayer := gismanager.GdalLayer{
         Layer: &layer,
       }
       if newLayer, postgisErr := gLayer.LayerToPostgis(targetSource, manager, true); newLayer.Layer != nil || postgisErr != nil {
         ok, pubErr := manager.PublishGeoserverLayer(newLayer)
         if pubErr != nil {
           logger.Error(pubErr)
         }
         if !ok {
           logger.Error("Failed to Publish")
         } else {
           logger.Info("published")
         }
       }

     }
   }
 }

done check you geoserver or via geoserver rest api url http://localhost:8080/geoserver/rest/layers.json :

 {
   "layers": {
     "layer": [..., {
       "name": "golang:hwy_patrol",
       "href": "http:\/\/localhost:8080\/geoserver\/rest\/layers\/golang%3Ahwy_patrol.json"
     }, {
       "name": "golang:neighborhood_names_gis",
       "href": "http:\/\/localhost:8080\/geoserver\/rest\/layers\/golang%3Aneighborhood_names_gis.json"
     }, {
       "name": "golang:nyc_wi_fi_hotspot_locations",
       "href": "http:\/\/localhost:8080\/geoserver\/rest\/layers\/golang%3Anyc_wi_fi_hotspot_locations.json"
     }]
   }
 }

Todo:

backup postgis as geopackage
