4.2.1 Summary of Steps for Offering a GeoTiff dataset

We are assuming that geoserver is correctly installed in your machine, if not, we recommend you to follow the steps described in www.geoserver.org

4.2.1.1 Case 1: How to publish a single GeoTIFF data wth geoserver

Step 1. Create a New Workingspace.
In order to serve GeoTIFF data, we need to create a new Working Space where we are going to store all our project

Step 2. Create a New Store.

Step 3. Add a New Source.
When adding a new Source we are going to specify wich kind of layer we want to upload. We are going to Add a New raster Layer choosing the option of GeoTIFF images on the New Data Source.

Step 4. Add a New Layer.
Here we are going to fill in all the required parameters that describes our new layer. Geoserver is going to generate all the files needed. Ones we Save all the information,we should be able to view the new layer on the list of layer of our geoserver

4.2.1.2 Case 2: How to publish a GeoTIFF mosaic wth geoserver

Start your Geoserver and log in into your geoserverweb Administration interface.

Important Note: All GeoTIFF images that will be part of the mosaic must be stored in a single foulder for geoserver to use correctly the ImageMosaic Plugin.

Step 1. Create a New Workingspace.
In order to serve GeoTIFF data, we need to create a new Working Space where we are going to store all our project

Step 2. Create a New Store.

Here is where the mosaic will be held.

Step 3. Add a New Source.
When adding a new Source we are going to specify wich kind of layer we want to upload. To generate a mosaic we are going to select the ImageMosaic Plugin on the Add a New Data Source.

Step 4. Add a New Layer.
Here we are going to fill in all the required parameters that describes our new layer. This Plugin will automatically generate the Index.shp file, the .proj file and the configuration.properties file needed. When Adding the new Layer, we are going to fill in all the information required and Save it. This new image-mosaic should be visible on your geoserver list of layers.

Finally we are going to test the server.

4.2.2 Summary of Steps for TRMM Precipitation Data with GMU CSISS’s WCS

4.2.2.1 Install GMU WCS package

The first step is to get the GMU WCS open-source package, and install the package correctly. The related software and libraries need to be downloaded and configured correctly, and the software development environment is also required to set up.

4.2.2.2 Configure GMU WCS to serve TRMM data

In order to serve TRMM data through GMU WCS, the WCS developers need to download TRMM data and archive the data to WCS server, and then modify WCS configuration file accordingly.

4.2.2.3 Extend GMU WCS to support other data type

In this release, GMU WCS supports HDF-EOS2, HDF-EOS5, GeoTIFF and NetCDF dataset coverage. The WCS developer could extend GMU WCS based on existing framework to support other data format.

4.2.2.4 Register GMU WCS to GEOSS CSR system

Once the GMU WCS has been installed and configured well, the developer could serve the data which supported by GMU WCS package, or extend it to support more data types. After the testing, the developer could register its WCS instance to GEOSS CSR system, to make it accessible through GEO portal.

4.2.3 Summary of Steps for Multidimensonal data with Rasdaman

Following the installation of the rasdaman, data can be ingested.

Data upload to rasdaman can be done by WCS-T (more in the lines of the OGC) or by cloning an existing SQL

Adding new objects through request

Stablishing a new coverage in the server

Registration with the GEOSS components
