reporting
Until now, equivalent tools were existing for other programming languages (e.g. Java, Python) but not in R. geosapi intends to provide R native interface to the GeoServer REST API, in order to facilitate publication of geographic data resources from R to GeoServer.
Package distributed under MIT license.
If you use geosapi
, i would be very grateful if you can
add a citation in your published work. By citing geosapi
,
beyond acknowledging the work, you contribute to make it more visible
and guarantee its growing and sustainability. You can get the preferred
citation by running citation("geosapi)
in R.
For now, the package can be installed from Github
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).
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

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

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$setVirtualTable(vt)
featureType
#fetch featureType and update some properties
featureType <- gsman$getFeatureType("topp", "taz_shapes", "tasmania_cities2")
featureType$setAbstract("abstract updated")
featureType$setEnabled(FALSE)
#update featureType in GeoServer
updated <- gsman$updateFeatureType("topp", "taz_shapes", featureType)
layers
GeoServer API doc: https://docs.geoserver.org/stable/en/user/rest/api/layers.html
layer(s)
layer
This method shows how to publish a created
featureType
(as created in 4.5.3
Create a new FeatureType
)
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.
The method publishLayer
will sequentially do two
requests to GeoServer:
featureType

#create featuretype
featureType <- GSFeatureType$new()
featureType$setName("tasmania_cities2")
featureType$setNativeName("tasmania_cities")

The geosapi
offers methods to upload coverage data to
configured coveragestores
. A generic method

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)
style
(s)From GeoServer 2.2, it is also possible to get the content of a style, ie the SLD body:
style
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).
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:
To get a workspace settings, use the following code:
This method can be used in view of updating a workspace 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.
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:
wmsSettings <- gsman$getWmsSettings()
wmsSettings$setTitle("Tile for my global WMS")
updated <- gsman$updateServiceSettings(wmsSettings, service = "WMS")
Shortcut update methods are also available. The last code line above can be replaced by:
wmsSettings <- GSServiceSettings$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")
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
#disable global WMS
gsman$disableWMS()
#enable global WFS and WCS
gsman$enableWFS()
gsman$enableWCS()
#activates WMS for workspace 'geosapi'
enabled <- gsman$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")
