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

- How to install:
- `go get -v github.com/hishamkaram/gismanager`
- Usage:
- 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(),
}
```
- `testdata` folder content:
```
./testdata/
├── neighborhood_names_gis.geojson
├── nested
│   └── nyc_wi-fi_hotspot_locations.geojson
├── sample.gpkg
```
- 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")
}
}
}
}
}
```
- output:
```

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