This post will cover creating an ImageMosaic data store with GeoServer.<\/p>\n\n\n\n

If you have image files prepared, you can skip the “Prepare Files” section below.<\/p>\n\n\n\n

Prepare files<\/strong><\/p>\n\n\n\n

We will use the London GeoTIFF image from PlanetSAT geospatial-data-samples<\/a> to create our mosaic. <\/p>\n\n\n\n

Create new directory ‘london’ in your GeoServer data\/data directory.<\/p>\n\n\n\n

su - tomcat\ncd \/home\/tomcat-version\/webapps\/geoserver\/data\/data\nmkdir london\ncd london\nwget https:\/\/demo.planetobserver.com\/PlanetObserver_PlanetSAT_10m_UK_London_UTM30.zip\nunzip PlanetObserver_PlanetSAT_10m_UK_London_UTM30.zip \nrm -f PlanetObserver_PlanetSAT_10m_UK_London_UTM30.zip <\/pre>\n\n\n\n
Now, still in our ‘london’ directory, let’s use gdal to create our tiles:<\/p>\n\n\n\n
mkdir tiles\ngdal_retile.py -v -r bilinear -levels 1 -ps 512 512 -co \"TILED=YES\" -co \"COMPRESS=JPEG\" -targetDir tiles PlanetObserver_PlanetSAT_10m_UK_London_UTM30.tif\n<\/pre>\n\n\n\n
After this we can remove the large TIFF file. <\/p>\n\n\n\n
Note:<\/strong> gdal_retile.sh is part of the gdal-bin package in Ubuntu.<\/p>\n\n\n\n
Create a Workspace<\/strong><\/p>\n\n\n\n
We’ll create a workspace, called “mosaic” as below.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Optional: Use PostGIS<\/strong><\/p>\n\n\n\n
The ImageMosaic plugin generates a shape file for use with the Mosaic. <\/p>\n\n\n\n
If we wish to store this information in a PostGIS database, we can do so by adding a  datastore.properties file to the Mosaic directory.<\/p>\n\n\n\n
You will need an existing PostGIS database or to create a database (it will not be created for you).<\/p>\n\n\n\n
The contents of the  datastore.properties file should look as below.<\/p>\n\n\n\n
SPI=org.geotools.data.postgis.PostgisNGDataStoreFactory\nhost=localhost\nport=5432\ndatabase=mydb\nschema=public\nuser=mydbuser\npasswd=SuperSecret\nLoose\\ bbox=true\nEstimated\\ extends=false\nvalidate\\ connections=true\nConnection\\ timeout=10\npreparedStatements=true<\/pre>\n\n\n\n
Create the Data Store<\/strong><\/p>\n\n\n\n
Go to Data \/ Stores\/ Add New<\/p>\n\n\n\n
Click on ImageMosaic in Raster Data Sources<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Select our workspace (mosaic) and enter “london<\/strong>” as store name<\/p>\n\n\n\n
Browse to the $MOSAIC_DIR\/ as URL.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Click OK and then click Save<\/p>\n\n\n\n
Create a New Layer<\/strong><\/p>\n\n\n\n
Go to Data \/ Layers \/ Add a new layer<\/p>\n\n\n\n
Select the mosaic:london<\/strong> entry<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Click on Publish. <\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
You will be taken to the “Edit Layer” menu, where you can change some parameters.<\/p>\n\n\n\n
You can edit various layer properties, as title, abstract, etc. In “Coverage Parameters” you can set ‘Multithreaded granule loading’, if you have multi-core CPU.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
When ready, click the Save button.<\/p>\n\n\n\n
View the Mosaic<\/strong><\/p>\n\n\n\n
Go to Data \/ Layer Preview<\/p>\n\n\n\n
Find the “mosaic:london<\/strong>” in Name column. You can use the search box on top<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
<\/p>\n\n\n\n
Click on OpenLayers to view it. You can zoom in\/out and move around the map.<\/p>\n\n\n\n
