Open Source Cloud GIS System Setup with Amazon EC2 and Geoserver

Follow these steps to set up the open source cloud based GIS mapping system.

1. Create an Amazon Web Services (AWS) account. You can find instructions for this step in the EC2 Getting Started Guide.

3. Create an Amazon EC2 instance. Instructions are also in the EC2 Getting Started Guide. When choosing an AMI make sure you choose a Windows server with IIS (and ASP.NET) already installed.

4. Connect to your Windows EC2 instance and install GeoServer. You can download GeoServer here. There are multiple setups available. Use the Windows installer. The instructions for the install are here.

5. Copy GIS data and configure map layers. The GeoServer user's manual will guide you through the steps of configuring GeoServer.

6. Start GeoServer on the EC2 instance server.

7. Seed the layers in GeoWebCache on the server. Instructions for this are here. Note that jpeg tiles are smaller than png and the default for base layers. Also png are better quality and will always be used for overlays because they can be transparent and overlays need to support transparency. Seed all layers for zoom levels 0 to 10 for EPSG:4326. If it is a base layer, seed it with jpeg files. If it is an overlay layer, seed it with png files.

8. Install the open source map application client built in OpenLayers or Leaflet on the server.

9. Test the application on a browser. If you receive an 'Access to the path is denied' error for any function, you will need to right click the folder and grant full control to the IIS_WPG user in the security tab.
