publishing spatial data to the web• Fast, flexible, reliable, and highly integratable• Support of various OGC standards: WMS, WFS,

WCS, SLD, SOS, etc.• Current release: 6.0.3; 6.2 in preparation• 16+ active developers; ~300k LoC;

Overview MapServer

INSPIRE View Service in MapServer

• Available with MapServer 6.2 release

• WMS 1.3.0

• Based on Technical Guidance in version 3.0

• Documentationhttp://mapserver.org/trunk/ogc/inspire.htmlwith 6.2 release http://mapserver.org/ogc/inspire.html

• Implementation tracked as RFC 75http://mapserver.org/development/rfc/ms-rfc-75.html

• Validates against INSPIRE schemas

• Tested against WMS INSPIRE testerhttp://inspire_tester.neogeo-online.net

Activation of INSPIRE support

• scenario 1: external metadata: "url"• scenario 2: embedded metadata: "embed"

WEB METADATA "wms_inspire_capabilities" "url" ... ENDEND

Multi-language support (1/3)

• Provisioning of all supported languages• Values according to ISO 639-2/B• First value is default language

WEB METADATA … "wms_languages" "eng,ger,ita" ... ENDEND

Multi-language support (2/3)

WEB METADATA "wms_title.eng" "Transport Network" "wms_title.ger" "Verkehrsnetz" "wms_abstract" "myabstract" ... ENDEND

...&REQUEST=GetCapabilities&LANGUAGE=eng

Multi-language support (3/3)

• Run-time substitution (only CGI)• DATA & CONNECTION metadata

LAYER NAME TN.RoadTransportNetwork.RoadArea DATA "road_%language%.shp" ...END

...&REQUEST=GetMap&LANGUAGE=eng

INSPIRE specific metadata - Scenario 1

"wms_inspire_metadataurl_href" "http://..."

"wms_inspire_metadataurl_format" "application/vnd.ogc.csw.capabilities.response_xml"

"wms_keywordlist_vocabulary" "ISO"

"wms_keywordlist_ISO_items" "infoMapAccessService"

"wms_fees" "conditions unknown"

"wms_accessconstraints" "None"

"wms_contactorganization" "MapServer"

"wms_contactposition" "owner"

...

INSPIRE specific metadata - Scenario 2

Additional metadata:"wms_inspire_temporal_reference" "2012-05-22""wms_inspire_mpoc_name" "mympocname""wms_inspire_mpoc_email" "mympoc@e.mail""wms_inspire_metadatadate" "2012-05-22""wms_inspire_resourcelocator" "http://resource"

• Values are not validated• Some metadata is hard-coded

Named group layers (1/2)

• Via wms_layer_group• Arbitrary depth• Named vs. Unnamed• Supported in GetMap,

GetFeatureInfo, etc.

LAYER NAME RoadArea METADATA "wms_layer_group" "/RoadTransportNetwork" …

Named group layers (2/2)

MAP NAME TN …LAYER NAME RoadTransportNetwork ...LAYER NAME RoadArea METADATA "wms_layer_group" "/RoadTransportNetwork" …

• Only TN and RoadArea can be requested

• RoadTransportNetwork only used for grouping

unnamed
