4.1 How to install geosapi in R

For now, the package can be installed from Github

install.packages("devtools")

Once the devtools package loaded, you can use the install_github to install geosapi. By default, package will be installed from master`` which is the current version in development (likely to be unstable).

require("devtools")
install_github("eblondel/geosapi")

4.2 Connect to GeoServer REST API

The main entry point of geosapi is the GSManager. To configure it, enter the following line, specifying the base URL of your GeoServer, and your credentials:

gsman <- GSManager$new(
    url = "http://localhost:8080/geoserver", #baseUrl of the Geoserver
    user = "admin", pwd = "geoserver", #credentials
    logger = NULL #logger, for info or debugging purpose
)

By default, the geosapi logger is deactivated. To enable the logger, specify the level of log you wish as parameter of the above R code. Two logging levels are available:

INFO: will print the geosapi logs. Three types of messages can be distinguished: INFO, WARN, ERROR. The latter is generally associated with a stop and indicate an blocking error for the R method executed.
DEBUG will print the above geosapi logs, and report all logs from HTTP requests performed with cURL

The GSManager inherits all methods of resource dependent managers, to provide the users with a single R interface to GeoServer REST API operations. In addition, the GSManager allows accessing the different resource managers through specific methods. The following managers are available:

GSNamespaceManager: Manage namespaces
GSWorkspaceManager: Manage workspaces
GSDataStoreManager: Manage dataStores

4.3 Manipulate GeoServer `workspaces`

GeoServer API doc: http://docs.geoserver.org/stable/en/user/rest/api/workspaces.html

4.3.1 Get a (list of) `workspace(s)`

  #get workspace objects
  wslist <- gsman$getWorkspaces()

  #get workspace names only

GeoServer API doc: http://docs.geoserver.org/stable/en/user/rest/api/datastores.html

4.5.1.1 Get a (list of) `dataStore(s)`

  #get datastore objects
  dslist <- gsman$getDataStores("topp")

  #get datastore names only
  dsnames <- gsman$getDataStoreNames("topp")

  #get datastore by name
  ns <- gsman$getDataStore("topp", "states_shapefile")

4.5.1.2 Create a new `dataStore`

4.5.1.2.1 Create a Shapefile dataStore

  ds = GSShapefileDataStore$new(dataStore="topp_datastore",
                                description = "topp_datastore description",
                                enabled = TRUE,
                                url = "file:data/shapefiles/states.shp")
  created <- gsman$createDataStore("topp", ds)

4.5.1.2.2 Create a Shapefiles Directory dataStore

  ds = GSShapefileDirectoryDataStore$new(dataStore="topp_datastore",
                                description = "topp_datastore description",
                                enabled = TRUE,
                                url = "file:data/shapefiles")
  created <- gsman$createDataStore("topp", ds)

4.5.1.2.3 Create a GeoPackage dataStore

  ds = GSGeoPackageDataStore$new(dataStore="topp_datastore",
                                description = "topp_datastore description",
                                enabled = TRUE,
                                database = "file:data/somefile.gpkg")
  created <- gsman$createDataStore("topp", ds)

4.5.1.3 Update an existing `dataStore`

  dataStore <- gsman$getDataStore("topp", "topp_datastore")
  dataStore$setDescription("topp_datastore updated description")
  dataStore$setEnabled(FALSE)
  
  updated <- gsman$updateDataStore("topp", dataStore)

4.5.1.4 Delete an existing `dataStore`

  deleted <- gsman$deleteDataStore("topp", "topp_datastore", recurse = TRUE)

The recurse parameter allows to delete all layers published under the deleted datastore.

4.5.2 Upload features/vector data

The geosapi offers methods to upload vector data to configured datastores. A generic method gsman$uploadData allows to upload any kind of data type supported by GeoServer, by specifying the file extension. To upload data, several parameters have to be specified including:

ws: the workspace in which the datastore is configured
ds: the datastore in which data has to be uploaded
endpoint: choice among file (use a local file content as body), url (use a file URL), or external (path to a file). Important note: So far only file was tested and is supported.
extension: the data file extension
configure: either none (upload only, with no featuretype/layer configured by default), first (upload and configure featuretype/layer over the uploaded vector data)
update: update strategy, either append (upload that will fails in case data was already uploaded), or overwrite (overwrite the already uploaded data if existing)
filename: filename of the data resource to upload
charset: character set of the data resource
`contentType: data content type

To simplify the upload, several data-specific methods were designed targeting specific data file extensions. These methods share the same parameters as above except the extension and contentType that will be pre-set according to the data upload format:

uploadShapefile: upload a shapefile
uploadProperties: upload a properties file
uploadH2: upload a H2 database
uploadSpatialite: upload a spatialite file
uploadAppSchema: upload an app schema
uploadGeoPackage: upload an OGC GeoPackage

Example with an OGC Geopackage upload

  uploaded <- gsman$uploadGeoPackage(
	ws = "my_workspace", ds = "my_gpkg_datastore",
	endpoint = "file", configure = "first", update = "overwrite",
	charset = "UTF-8", filename = "myfile.gpkg"
  )

4.5.3 Manipulate GeoServer `featureType`

GeoServer API doc: http://docs.geoserver.org/stable/en/user/rest/api/featuretypes.html

4.5.3.1 Get a (list of) `featureType(s)`

  #get featureType objects
  ftlist <- gsman$getFeatureTypes("topp", "taz_shapes")

  #get featureType names only
  ftnames <- gsman$getFeatureTypeNames()

  #get featureType by name
  ft <- gsman$getFeatureType("topp", "taz_shapes", "tasmania_cities")

4.5.3.2 Create a new `featureType`

  #create featuretype object
  featureType <- GSFeatureType$new()
  featureType$setName("tasmania_cities2")
  featureType$setNativeName("tasmania_cities")
  featureType$setAbstract("abstract")
  featureType$setTitle("title")
  featureType$setSrs("EPSG:4326")
  featureType$setNativeCRS("EPSG:4326")
  featureType$setEnabled(TRUE)
  featureType$setProjectionPolicy("REPROJECT_TO_DECLARED")
  featureType$setLatLonBoundingBox(-180,-90,180,90, crs = "EPSG:4326")
  featureType$setNativeBoundingBox(-180,-90,180,90, crs ="EPSG:4326") 
  
  md1 <- GSMetadataLink$new(type = "text/xml", metadataType = "ISO19115:2003", content = "http://somelink.org/xml")
  featureType$addMetadataLink(md1)
  md2 <- GSMetadataLink$new(type = "text/html", metadataType = "ISO19115:2003", content = "http://somelink.org/html")
  featureType$addMetadataLink(md2)

  #create the feature type in GeoServer
  created <- gsman$createFeatureType("topp", "taz_shapes", featureType)

How to set a Geoserver SQL View

With geosapi, it is also possible to configure a Geoserver SQL View, possibly with dynamic parameters. For this, GeoServer uses the concept of VirtualTable. The code below explains how to configure such virtual table with geosapi:

##virtual table
vt <- GSVirtualTable$new()
vt$setName("view name")
vt$setSql("select * from mydataset where flag = '%flag%' and year between %start_year% and %end_year%")

## incase of spatial virtual table, specify the geometry column name, type and SRID
vtg <- GSVirtualTableGeometry$new(name = "the_geom", type = "MultiPolygon", srid = 4326)
vt$setGeometry(vtg)

##in case of dynamic parameters handled in your sql (bound with %)
vtp1 <- GSVirtualTableParameter$new(name = "flag", defaultValue = "FRA", regexpValidator = "^[\\w\\d\\s]+$")
vtp2 <- GSVirtualTableParameter$new(name = "start_year", defaultValue = "2000",regexpValidator = "^[\\d]+$")
vtp3 <- GSVirtualTableParameter$new(name = "end_year", defaultValue = "2010",regexpValidator = "^[\\d]+$")
vt$addParameter(vtp1)
vt$addParameter(vtp2)
vt$addParameter(vtp3)

##add virtual table to featureType
featureType$setVirtualTable(vt)

4.5.3.3 Update an existing `featureType`

  #fetch featureType and update some properties
  featureType <- gsman$getFeatureType("topp", "taz_shapes", "tasmania_cities2")
  featureType$setAbstract("abstract updated")
  featureType$setEnabled(FALSE)
  
  #update featureType in GeoServer
  updated <- gsman$updateFeatureType("topp", "taz_shapes", featureType)

4.5.3.4 Delete an existing `featureType`

  deleted <- gsman$deleteFeatureType("topp", "taz_shapes", "tasmania_cities2", recurse = TRUE)

The recurse parameter allows to delete the layer published for the deleted featureType.

4.5.4 Manipulate GeoServer `layers`

GeoServer API doc: http://docs.geoserver.org/stable/en/user/rest/api/layers.html

4.5.4.1 Get a (list of) `layer(s)`

  #get layer objects
  layers <- gsman$getLayers()

  #get layer names only
  layerNames <- gsman$getLayerNames()

  #get layer by name
  layer <- gsman$getLayer("tasmania_cities")

4.5.4.2 Create a new `layer`

This method shows how to publish a created featureType (as created in 4.5.3 Create a new FeatureType)

  layer <- GSLayer$new()
  layer$setName("tasmania_cities2")
  layer$setDefaultStyle("capitals")
  layer$addStyle("generic")
  created <- gsman$createLayer(layer)

4.5.4.3 Update an existing `layer`

  lyr <- gsman$getLayer("tasmania_cities")
  lyr$setDefaultStyle("generic")
  updated <- gsman$updateLayer(lyr)

4.5.4.4 Delete an existing `layer`

  deleted <- gsman$deleteLayer("tasmania_cities2")

4.5.5 Publication of GeoServer feature layer

GeoServer manages feature data layers by means of two different types of resources: the featureType and the layer. When created, the latter will publish the former. Hence, in order to publish a complete feature data layer, two GeoServer resources should be created. The below methods allow the user to do both creation through a single method. To distinguish them from the above API methods and avoid confusion, we don't use the terminology create / delete but publish / unpublish.

4.5.5.1 Publish Geoserver feature layer

The method publishLayer will sequentially do two requests to GeoServer:

Create featureType
Create layer

  #create featuretype
  featureType <- GSFeatureType$new()
  featureType$setName("tasmania_cities2")
  featureType$setNativeName("tasmania_cities")
  featureType$setAbstract("abstract")
  featureType$setTitle("title")
  featureType$setSrs("EPSG:4326")
  featureType$setNativeCRS("EPSG:4326")
  featureType$setEnabled(TRUE)
  featureType$setProjectionPolicy("REPROJECT_TO_DECLARED")
  featureType$setLatLonBoundingBox(-180,-90,180,90, crs = "EPSG:4326")
  featureType$setNativeBoundingBox(-180,-90,180,90, crs ="EPSG:4326") 
  md1 <- GSMetadataLink$new(type = "text/xml", metadataType = "ISO19115:2003", content = "http://somelink.org/xml")
  featureType$addMetadataLink(md1)
  md2 <- GSMetadataLink$new(type = "text/html", metadataType = "ISO19115:2003", content = "http://somelink.org/html")
  featureType$addMetadataLink(md2)
  
  #create layer
  layer <- GSLayer$new()
  layer$setName("tasmania_cities2")
  layer$setDefaultStyle("capitals")
  layer$addStyle("generic")
  
  #try to publish the complete layer (featuretype + layer)
  published <- gsman$publishLayer("topp", "taz_shapes", featureType, layer)

4.5.5.2 Unpublish Geoserver feature layer

The method publishLayer will sequentially do two requests to GeoServer:

Delete layer
Delete featureType

  #try to unpublish the complete layer (featuretype + layer)
  published <- gsman$unpublishLayer("topp", "taz_shapes", "tasmania_cities2")

4.5.6 Manipulate GeoServer `layer groups`

GeoServer API doc: http://docs.geoserver.org/stable/en/user/rest/api/layergroups.html

4.5.6.1 Get a (list of) `layer group(s)`

  #get layer groups objects
  layerGroups <- gsman$getLayerGroups()

  #get layer group names only
  layerGroupNames <- gsman$getLayerGroupNames()

  #get layer group by name
  layerGroup <- gsman$getLayerGroup("test_layergroup")

4.5.6.2 Create a new `layer group`

  lyr <- GSLayerGroup$new()
  lyr$setName("test_layergroup")
  lyr$setTitle("title")
  lyr$setAbstract("abstract")
  lyr$setMode("SINGLE")
  lyr$addLayer(layer = "tasmania_cities", style = "generic")
  lyr$setBounds(-180,-90,180,90,crs = "EPSG:4326")
  gsman$createLayerGroup(layerGroup = lyr)

4.5.6.3 Update an existing `layer group`

  lyr <- GSLayerGroup$new()
  lyr$setName("test_layergroup")
  lyr$setTitle("title")
  lyr$setAbstract("abstract 2")
  lyr$setMode("SINGLE")
  lyr$addLayer(layer = "tasmania_cities", style = "generic")
  lyr$setBounds(-180,-90,180,90,crs = "EPSG:4326")
  gsman$updateLayerGroup(layerGroup = lyr)

4.5.6.4 Delete an existing `layer group`

  deleted <- gsman$deleteLayerGroup("test_layergroup")

4.6. Manage raster data with GeoServer

4.6.1 Manipulate GeoServer `coveragestores`

GeoServer API doc: http://docs.geoserver.org/stable/en/user/rest/api/coveragestores.html

  cs = GSGeoTIFFCoverageStore$new(name="sfdem_new", description = "sfdem_new description", enabled = TRUE)
  created <- gsman$createCoverageStore("sf", cs)

4.6.1.2.2 Create a WorldImage coveragestore

  cs = GSWorldImageCoverageStore$new(name="sfdem_new", description = "sfdem_new description", enabled = TRUE)
  created <- gsman$createCoverageStore("sf", cs)

4.6.1.2.3 Create a ArcGrid coveragestore

  cs = GSArcGridCoverageStore$new(name="sfdem_new", description = "sfdem_new description", enabled = TRUE)
  created <- gsman$createCoverageStore("sf", cs)

4.6.1.2.4 Create a ImageMosaic coveragestore

  cs = GSImageMosaicCoverageStore$new(name="sfdem_new", description = "sfdem_new description", enabled = TRUE)
  created <- gsman$createCoverageStore("sf", cs)

4.6.1.3 Update an existing `coveragestore`

  cs <- gsman$getCoverageStore("sf", "sfdem")
  cs$setDescription("sfdem updated description")
  cs$setEnabled(FALSE)
  
  updated <- gsman$updateCoverageStore("sf", cs)

4.6.1.4 Delete an existing `coveragestore`

  deleted <- gsman$deleteCoverageStore("sf", "sfdem", recurse = TRUE)

The recurse parameter allows to delete all coverages published under the deleted coveragestore.

4.6.2 Upload coverage/raster data

The geosapi offers methods to upload coverage data to configured coveragestores. A generic method gsman$uploadCoverage allows to upload any kind of coverage data type supported by GeoServer, by specifying the file extension. To upload data, several parameters have to be specified including:

ws: the workspace in which the datastore is configured
ds: the datastore in which data has to be uploaded
endpoint: choice among file (use a local file content as body), url (use a file URL), or external (path to a file). Important note: So far only file was tested and is supported.
extension: the data file extension
configure: either none (upload only, with no coverage/layer configured by default), first (upload and configure coverae/layer over the uploaded data)
update: update strategy, either append (upload that will fails in case data was already uploaded), or overwrite (overwrite the already uploaded data if existing)
filename: filename of the data resource to upload
charset: character set of the data resource
`contentType: data content type

To simplify the upload, several coverage-specific methods were designed targeting specific data file extensions. These methods share the same parameters as above except the extension and contentType that will be pre-set according to the data upload format:

uploadGeoTIFF: upload a GeoTIFF file
uploadWorldImage: upload a WorldImage file
uploadArcGrid: upload an ArcGrid file
uploadImageMosaic: upload an ImageMosaic

Example with a GeoTIFF upload

  uploaded <- gsman$uploadGeoTIFF(
	ws = "sf", cs = "sfdem_new",
    endpoint = "file", configure = "none", update = "overwrite",
    filename = system.file("extdata/sfdem_new.tif", package = "geosapi")
  )

4.6.3 Manipulate GeoServer `coverages`

GeoServer API doc: http://docs.geoserver.org/stable/en/user/rest/api/coverages.html

4.6.3.1 Get a (list of) `coverage(s)`

How to set a Geoserver Coverage View

With geosapi, it is also possible to configure a Geoserver Coverage View. For this, GeoServer uses the concept of CoverageView. The code below explains how to configure such coverage view with geosapi:

  ##coverage view
  coview <- GSCoverageView$new()
  coview$setName("sfdem_new")
  coview$setEnvelopeCompositionType("INTERSECTION")
  coview$setSelectedResolution("BEST")
  coview$setSelectedResolutionIndex(-1)
  coviewband <- GSCoverageBand$new()
  coviewband$setDefinition("sfdem_new@0")
  coviewband$setIndex(0)
  coviewband$addInputBand(GSInputCoverageBand$new( coverageName = "sfdem_new", band = 0))
  coview$addBand(coviewband)

  ##add coverage view to coverage
  cov$setView(coview)

4.6.3.3 Update an existing `coverage`

  #fetch coverage and update some properties
  cov <- gsman$getCoverage("sf", "sfdem", "sfdem")
  cov$setAbstract("abstract updated")
  cov$setEnabled(FALSE)
  
  #update coverage in GeoServer
  updated <- gsman$updateCoverage("sf", "sfdem", cov)

4.6.3.4 Delete an existing `coverage`

  deleted <- gsman$deleteCoverage("sf", "sfdem", "sfdem", recurse = TRUE)

The recurse parameter allows to delete the layer published for the deleted featureType.

4.7. Manage styles with GeoServer

4.7.1 Get a (list of) `style`(s)

  styles <- gsman$getStyles()
  stylenames <- gsman$getStyleNames()
  style <- gsman$getStyle("capitals")

From GeoServer 2.2, it is also possible to get the content of a style, ie the SLD body:

  sld <- gsman$getSLDBody("capitals")

4.7.2 Create a new `style`

  sldFile <- system.file("extdata", "mystyle.sld", package = "geosapi") #to use 'file' argument of gsman$createStyle
  sldStyle <- xmlParse(sldFile) #to use 'sldBody' argument of gsman$createStyle
  created <- gsman$createStyle(file = sldFile, name = "mystyle")

4.7.3 Update a new `style`

  sldFile2 <- system.file("extdata", "mystyle2.sld", package = "geosapi") #to use 'file' argument of gsman$updateStyle
  sldStyle2 <- xmlParse(sldFile2) #to use 'sldBody' argument of gsman$updateStyle
  updated <- gsman$updateStyle(sldBody = sldStyle2, name = "mystyle")

4.7.4 Delete an existing `style`

  deleted <- gsman$deleteStyle("mystyle", recurse = TRUE, purge = TRUE)

All methods describe here above also support a ws argument where a workspace can be specified.

4.8. Manage workspace settings with GeoServer

Geoserver allows to activate settings by workspace. In such case, this will overwrite the global Geoserver settings. Activating these settings is required to set-up specific OGC service capabilities par workspace (see next section).

4.8.1 Create a workspace settings

Creating a workspace settings is equivalent to check the "Enabled" checkbox in the Settings section of a workspace edition page in the GeoServer UI. To create it (assuming a workspace named geosapi), run the following code:

settings <- GSWorkspaceSettings$new()
settings$setNumDecimals(5) #custom number of decimals for data published in this workspace
created <- gsman$createWorkspaceSettings("geosapi", settings)

4.8.2 Get a workspace settings

To get a workspace settings, use the following code:

geosapi_settings <- gsman$getWorkspaceSettings("geosapi")

This method can be used in view of updating a workspace settings.

4.8.3 Update a workspace settings

Similar method can be used for updating the workspace configuration:

settings <- gsman$getWorkspaceSettings("geosapi")
settings$setNumDecimals(9) #change number of decimals
created <- gsman$updateWorkspaceSettings("geosapi", settings)

4.8.4 Delete a workspace settings

The settings can be deleted (equivalent of unchecking the "Enabled" checkbox in a workspace settings section):

deleted <- gsman$deleteWorkspaceSettings("geosapi")

4.9 Manage OGC Service (WMS/WFS/WCS) settings with GeoServer

4.9.1 Get an OGC service (WMS/WFS/WCS) settings

To get an OGC service settings (global, or workspace specific), geosapi offers a generic method that can be used as follows:

#get WMS global settings
wms_global_settings <- gsman$getServiceSettings(service = "WMS")

#get WMS geosapi settings
wms_geosapi_settings <- gsman$getServiceSettings(service = "WMS", ws = "geosapi")

Shortcut methods can also be used as follow:

#get WMS global settings
wms_global_settings <- gsman$getWmsSettings()

#get WMS geosapi settings
wms_geosapi_settings <- gsman$getWmsSettings(ws = "geosapi")

Analog methods are available for WFS and WCS.

4.9.2 Update an OGC service (WMS/WFS/WCS) settings

OGC service settings can be updated, for example to activate/deactivate the service and fill minimum metadata (name, title, abstract). The following examples shows how to do update WMS global configuration and by workspace:

Update the WMS global configuration:

wmsSettings <- gsman$getWmsSettings()
wmsSettings$setTitle("Tile for my global WMS")
updated <- gsman$updateServiceSettings(wmsSettings, service = "WMS")

Shortcut update methods are also available. The last code line above can be replaced by:

updated <- gsman$updateWmsSettings(wmsSettings)

Update WMS workspace configuration

wmsSettings <- GSServiceSettings$new(service = "WMS")
wmsSettings$setTitle("Tile for my workspace WMS")
wmsSettings$setAbstract("This WMS is set-up specifically for the workspace geosapi")
updated <- gsman$updateServiceSettings(wmsSettings, service = "WMS", ws = "geosapi")

The last code line above could be replaced by the shortcut method:

updated <- gsman$updateWmsSettings(wmsSettings, ws = "geosapi")

4.9.3 Enable/Disable an OGC service (WMS/WFS/WCS)

To make OGC service enabling/disabling easier for users, additional shortcut methods were set-up in geosapi. The following code examples show you how to enable/disable WMS/WFS/WCS

Enable/Disable Global OGC services

#disable global WMS
gsman$disableWMS()
#enable global WFS and WCS
gsman$enableWFS()
gsman$enableWCS()

Enable/Disable OGC services at workspace level

#activates WMS for workspace 'geosapi'
enabled <- gsman$enableWMS("geosapi")

#deactivates WMS for workspace 'geosapi'
disabled <- gsman$disableWMS("geosapi")

Analog functions are available for WFS and WCS:

#enable WFS and WCS for geosapi workspace
gsman$enableWFS("geosapi")
gsman$enableWCS("geosapi")

#disable WFS and WCS for geosapi workspace
gsman$disableWFS("geosapi")
gsman$disableWCS("geosapi")
