Olá, Estou a dar os meus primeiros passos com servidores de mapas, como é de esperar, ando um pouco perdido. Vou tentar explicar as minhas "peripécias" destes últimos dias e assim tratar de encontrar algumas luzes.
Estou a utilizar o seguinte ecossistema: - Ubuntu Server 10.4 LTS - sun-java6-jdk - Tomcat6 - Geoserver 2.0.2 (*.war)* [Native JAI] [Native JAI ImageIO]* - Postgresql_8.4/Postgis_1.5.0 *[**proj-bin libproj-dev gdal-bin postgresql-server-dev-8.4 libgdal-dev libgeos-dev build-essential libxml2-dev**]* - GDAL Estes são os passos mais importantes que estou a realizar, vou focar a explicação numa das layers (linhas) para simplificar mas acontece o mesmo com a outra layer de pontos que tenho. Qualquer detalhe que achem importante e esteja a esquecer/omitir, não duvidem em pedir!!!: - Importo o shape para Postgresql_8.4/Postgis_1.5.0, utilizando o Plugin do QGIS. Tabela que cria o Plugin: CREATE TABLE eixos_via_peniche ( gid integer NOT NULL, "ID" integer, "TOPONIMIA" character varying(254), the_geom geometry, CONSTRAINT eixos_via_peniche_pkey PRIMARY KEY (gid), CONSTRAINT enforce_dims_the_geom CHECK (st_ndims(the_geom) = 2), CONSTRAINT enforce_srid_the_geom CHECK (st_srid(the_geom) = 20791) ) WITH ( OIDS=FALSE ); ALTER TABLE eixos_via_peniche OWNER TO postgres; Dados que insere o Plugin na tabela geometry_columns *17673*;"''";"*public*";"*eixos_via_peniche*";"*the_geom*";*2*;*20791*;"* MULTILINESTRING*" - Publico a tabela no Geoserver 2.0.2 * *Todo corre aparentemente bem, todos os parâmetros por defeito, mmmh só “apenas” um ***warning no momento de fazer o publish (ao fim desta mensagem segue o texto do warning), mas depois se consegue visualizar a layer sem problemas via WMS utilizando o Layer Preview. - Experimento de fazer una transacção via Demos Request. <wfs:Transaction service="WFS" version="1.0.0" xmlns:wfs="http://www.opengis.net/wfs"; xmlns:topp="http://www.openplans.org/topp"; xmlns:gml="http://www.opengis.net/gml"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.0.0/WFS-transaction.xsd http://www.openplans.org/topp http://localhost:8080/geoserver/wfs/DescribeFeatureType?typename=topp:eixos_via_peniche "> <wfs:Insert> <topp:eixos_via_peniche> <topp:the_geom> <gml:MultiLineString srsName=" http://www.opengis.net/gml/srs/epsg.xml#4326";> <gml:lineStringMember> <gml:LineString> <gml:coordinates decimal="." cs="," ts=" "> 494475.71056415,5433016.8189323 494982.70115662,5435041.95096618 </gml:coordinates> </gml:LineString> </gml:lineStringMember> </gml:MultiLineString> </topp:the_geom> <topp:TYPE>alley</topp:TYPE> </topp:eixos_via_peniche> </wfs:Insert> </wfs:Transaction> Resultado da transacção: <wfs:WFS_TransactionResponse version="1.0.0" xsi:schemaLocation=" http://www.opengis.net/wfs http://192.168.58.173:8080/geoserver/schemas/wfs/1.0.0/WFS-transaction.xsd";> <wfs:InsertResult> <ogc:FeatureId fid="eixos_via_peniche.5134"/> </wfs:InsertResult> <wfs:TransactionResult> <wfs:Status> <wfs:*SUCCESS*/> </wfs:Status> </wfs:TransactionResult> </wfs:WFS_TransactionResponse> Verifico via WMS utilizando o Layer Preview, se consegue visualizar a layer e a linha inserida, também na tabela Postgis foi inserido o registo, tudo parece correr bem... - Agora chega o momento de experimentar o mesmo utilizando Openlayers. Para isto modifico o ficheri wfs-t.html que o Geoserver utiliza para mostrar um exemplo de utilização de WFS-T. <script type="text/javascript"> OpenLayers.IMAGE_RELOAD_ATTEMPTS = 3; var map; function init(){ map = new OpenLayers.Map('map'); var political = new OpenLayers.Layer.WMS( "State", "/geoserver/wms", {layers: 'topp:peniche', format: 'image/png'} ); *var roads = new OpenLayers.Layer.WFS(* *"Roads", * *"/geoserver/wfs",* *{typename: 'topp:eixos_via_peniche'},* *{* *typename: 'eixos_via_peniche', * *featureNS: 'http://www.openplans.org/topp', * *extractAttributes: false* *}* *);* *roads.style = OpenLayers.Util.applyDefaults({strokeColor: "#ff0000"}, * *OpenLayers.Feature.Vector.style["default"]);* var cities = new OpenLayers.Layer.WFS( "Cities", "/geoserver/wfs", {typename: 'topp:pontos_interese_peniche'}, { typename: 'pontos_interese_peniche', featureNS: 'http://www.openplans.org/topp', extractAttributes: false } ); cities.style = OpenLayers.Util.applyDefaults({strokeColor: "#0000ff"}, OpenLayers.Feature.Vector.style["default"]); map.addLayers([political, roads, cities]); var panel = new OpenLayers.Control.Panel( {displayClass: 'olControlEditingToolbar'} ); *var drawLine = new OpenLayers.Control.DrawFeature(* *roads, OpenLayers.Handler.Path,* *{displayClass: 'olControlDrawFeaturePath'}* *);* *drawLine.featureAdded = function(feature) {* *feature.layer.eraseFeatures([feature]);* *// cast to multilinestring* *feature.geometry = new OpenLayers.Geometry.MultiLineString(* *feature.geometry* *);* *feature.style.strokeColor = "#ff0000";* *feature.state = OpenLayers.State.INSERT;* *feature.layer.drawFeature(feature);* *}* var drawPoint = new OpenLayers.Control.DrawFeature( cities, OpenLayers.Handler.Point, {displayClass: 'olControlDrawFeaturePoint'} ); drawPoint.featureAdded = function(feature) { feature.layer.eraseFeatures([feature]); // cast to multipoint feature.geometry = new OpenLayers.Geometry.MultiPoint( feature.geometry ); feature.style.strokeColor = "#0000ff"; feature.state = OpenLayers.State.INSERT; feature.layer.drawFeature(feature); } *panel.addControls(* *[new OpenLayers.Control.Navigation(), drawLine, drawPoint]* *);* map.addControl(panel); map.addControl(new OpenLayers.Control.LayerSwitcher()); map.zoomToExtent( new OpenLayers.Bounds(-9.516,39.279,-9.255,39.421) ); } </script> </head> <body onload="init()"> <a href="# <view-source:file:///C:/Users/oscar/Desktop/wfs-t2.html#>" onclick="map.layers[1].commit();return false">Save Roads</a><br /> <a href="# <view-source:file:///C:/Users/oscar/Desktop/wfs-t2.html#>" onclick="map.layers[2].commit();return false">Save Cities</a> <div id="map"></div> </body></html> - Até agora tudo bem... tento visualizar o mapa resultante, e.., *não se conseguem visualizar as layers definidas como WFS*!!! só apenas a base layer definida como WMS. Mas, o surpreendente é que sim* se conseguem realizar transacções WFS-T com sucesso, inserindo novas linhas no mapa (e na base de dados), mas só conseguindo visualizar apenas as linhas acrescentadas com a interface do Openlayers*. Experimentando, observo que *só consigo visualizar todas as linhas via WMS utilizando o Layer Preview.* - Depois de todo isto decido aceder ao serviço WFS utilizando outro cliente, o uDig, e fico mesmo surpreendido ao ver que o resultado e totalmente o contrario que utilizando Openlayers, pois só consigo visualizar as linhas originais da layer e ano as que foram acrescentadas via WFS-T. Com tudo isto, insisto, e vou ao QGIS para tentar visualizar via WMS, também só consigo visualizar as linhas originais da layer, e voltando ao ponto anterior, só consigo visualizar todas linhas via WMS utilizando o* **Layer Preview *do geoserver. - Não estou seguro que seja importante, mas nos registos da *tabela eixos_via_peniche* é possível observar o seguinte: *Definição da tabela* gid integer NOT NULL, "ID" integer, "TOPONIMIA" character varying(254), the_geom geometry, CONSTRAINT eixos_via_peniche_pkey PRIMARY KEY (gid), CONSTRAINT enforce_dims_the_geom CHECK (st_ndims(the_geom) = 2), CONSTRAINT enforce_srid_the_geom CHECK (st_srid(the_geom) = 20791) *Linhas originais* *...* 5126;1606803;"";"010200002037510000020000005DB5847C877AFAC0284A598..." 5127;1606804;"";"010200002037510000030000005DB5847C877AFAC0284A598..." 5128;1606805;"";"010200002037510000040000007A7EFB3A6075FAC02844CF6..." *...* *Linhas acrescentadas mediante WFS-T*. O campo ID não contem nada e o campo TOPONIMIA esta como "" 5130;;"";"01050000203751000001000000010200000002000000DDC32973..." 5131;;"";"01050000203751000001000000010200000002000000DDC32973..." 5133;;"";"010500002037510000010000000102000000020000003E378941..." Até aqui chega a minha explicação, claramente omiti informações mas não queria que fosse eterno e cansar ao pessoal...qualquer informação que precisarem, digam!!! Agradeço qualquer *ajuda*, critica, ponto de vista... Desde já, muito obrigado!!! ====================================================== **warning* Oops, something went wrong...
