Google’s Cloud-based Earth Builder

Maintaining and scaling a GIS server can be challenging. In today’s economy, state and local governments and non-governmental organizations struggle with shrinking public budgets and fewer resources. Rod Erickson of Next Tier Concepts provides provides a solution using Software-as-a Service (SaaS).

A GIS requires the following components: hardware, software, databases, and people. A GIS server facilitates the storing and sharing of geospatial information such as imagery and vector data. Maintaining and scaling a GIS server can be challenging. In today’s economy, state and local governments and non-governmental organizations struggle with shrinking public budgets and fewer resources available to support a GIS; while concurrently incurring a greater demand from an increased number of users requesting map data and imagery as a web-based service. Google’s Earth Builder eliminates multiple layers of infrastructure and allows GIS data provider’s to focus on data without maintaining hardware, software, or databases.


The Earth Builder is a cloud-based Software-as-a-Service (SaaS); it eliminates the need for highly-trained information technology staff to administer and maintain a GIS server. As a result, users of Earth Builder such as United States Forest Service (USFS) and the Department of Defense can focus on their missions and support their users without the concerns, costs and overhead of maintaining a traditional GIS. Earth Builder enables organizations to pool resources and collaborate, which facilitates data sharing and reduces duplication of data hosted on multiple servers.

The Google Earth Builder SaaS interface and approach is based on the successful, intuitive Google Applications model for services such as Gmail and Documents already familiar to many users. Many consumers of geospatial data and imagery take advantage of products like Google Earth, and as professionals we may encounter the need to leverage a common and reliable geospatial base map as a resource. As of October of 2011, over one billion users have downloaded Google Earth. Regardless of user type, affiliation or service needs we all consume Google Earth from the same, single web-based resource.

The Earth Builder solution by Google is an innovative approach to storing and sharing geospatial data. Using this alternative to a traditional GIS solution, data managers and stewards such as NIFC reduce time and budgets required to serve geospatial data, imagery and a common base map. Expensive middleware and complex administration processes are replaced by a simple, intuitive Google Applications interface. It is time to stop serving the same pixels and vectors over and over again. Serve once and share many, many times.

The India-WRIS project

The India-WRIS project is a joint venture of Indian Space Research Organisation and Central Water Commission.It aims to develop an online, user friendly application that shall bring all information related to the water resources of the nation at single window wherefrom all the interested users can obtain it and make use of it. The vision of the project is to make available all water resources related data in standardized GIS form to the user community by achieving the objectives of creating and collecting all such data available through various sources. It's scope includes the generation and collection of data pertaining to 30 geospatial layers whose comprehensive information will be provide to the end user. This information will be dessiminated to the end user through a web based geo-spatial application which forms an integral part of the deliverables. The proposed web application will be released in a 2D-application form and also with the 3D View.

Maps give Europeans close-up picture of emissions from industrial facilities

Online maps published by the European Pollutant Release and Transfer Register (E-PRTR), allow users to pinpoint the key environmental data and the main sources of air pollution from industrial facilities across Europe. The European Pollutant Release and Transfer Register (E-PRTR) is the a Europe-wide register that provides easily accessible key environmental data from industrial facilities in European Union Member States and in Iceland, Liechtenstein, Norway, Serbia and Switzerland. It replaces and improves upon the previous European Pollutant Emission Register (EPER). The register contains data reported annually by some 28,000 industrial facilities covering 65 economic activities across Europe. The interactive map shows where certain pollutants are released from individual industrial plants. . The Europe-wide register aims to help Europeans actively engage in decisions affecting the environment. The map search option provides a geographical approach to the E-PRTR data. The map can even be viewed here in maximized version.

Landsat Time Enabled Imagery


View Larger Map
This map includes a variety of Landsat services which have been time enabled and can be explored using the Time Slider in the ArcGIS.COM Map Viewer or Explorer. Each layer has a predefined useful band combination already set on the services.

Data Source: This map includes image services compiled from the following Global Land Survey (GLS) datasets: GLS 2005, GLS 2000, GLS 1990, and GLS 1975. GLS datasets are created by the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) using Landsat images. These global minimal-cloud cover, orthorectified Landsat data products support global assessments of land-cover, land cover-change, and ecosystem dynamics such as disturbance and vegetation health.

Hazards Map (Japan)


View Larger Map
This web map shows active hazards, including earthquakes and volcanoes, near Japan. The web map features a live map service of global active hazards from the Pacific Disaster Center.
The web map also includes a map notes layer showing the location of a few active events with links for more information.  The map notes include the epicenter of the 9.0 magnitude earthquake and the location of the Fukushima nuclear plant that was damaged during the earthquake.
