GeoServer를 사용하여 PostGIS 래스터를 어떻게 게시합니까?
Image Mosaic JDBC를 사용하여 Raster 데이터 소스를 만들려고 많은 시간을 보냈지 만 운이 없습니다.
수행 된 단계 :
1. JDBC Image Mosaic 확장 프로그램 다운로드 및 설치 (정상 작동)
2. "연결 매개 변수"파일을 작성하십시오.
connect.postgis.xml.inc :
<connect>
<dstype value="DBCP"/>
<username value="postgres" />
<password value="password" />
<jdbcUrl value="jdbc:postgresql://localhost:5432/db1" />
<driverClassName value="org.postgresql.Driver"/>
<maxActive value="10"/>
<maxIdle value="0"/>
</connect>
mapping.postgis.xml.inc :
<spatialExtension name="postgis"/>
<mapping>
<masterTable name="mosaic" >
<coverageNameAttribute name="name"/>
<maxXAttribute name="maxX"/>
<maxYAttribute name="maxY"/>
<minXAttribute name="minX"/>
<minYAttribute name="minY"/>
<resXAttribute name="resX"/>
<resYAttribute name="resY"/>
<tileTableNameAtribute name="tiletable" />
</masterTable>
<tileTable>
<blobAttributeName name="rast" />
</tileTable>
</mapping>
osm.postgis.xml :
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE ImageMosaicJDBCConfig [
<!ENTITY mapping PUBLIC "mapping" "mapping.postgis.xml.inc">
<!ENTITY connect PUBLIC "connect" "connect.postgis.xml.inc">]>
<config version="1.0">
<coverageName name="gfm"/>
<coordsys name="EPSG:25832"/>
<!-- interpolation 1 = nearest neighbour, 2 = bilinear, 3 = bicubic -->
<scaleop interpolation="1"/>
<verify cardinality="false"/>
&mapping;
&connect;
</config>
여기서 "mosaic"은 하나의 행을 포함하는 테이블 (열 : name, titletable, minX, minY, maxX, maxY, resX, resY)입니다. "gfm, testrastertable,,,,,,,"
3. 구성 파일을에 저장했습니다. ./geoserver/data_dir/coverages/
4. 이미지 모자이크 JDBC 데이터 저장소를 추가하는 중에 다음 오류가 발생합니다.
Error: Could not list layers for this store, an error occurred retrieving them: Unable to acquire a reader for this coverage with format: ImageMosaicJDBC
