An excellent 3D Campus Map in Duke University

 

Similar to other colleges we’ve shown you in the past, such as Northeastern University, Duke University has just unveiled their new 3D campus map and it’s quite impressive.

With the help of concept3D, the map has become an excellent source of information for the school. Powered by the Concept3D “CampusBird Atlas” CMS, Duke staff can edit the map and publish new information on their own. In addition, all data is mirrored between the Google Earth Plugin API and the Google Maps API on the site; it appears seamless to the end user, but it’s a tricky piece of work on the back end.

The map includes 3D models of 325 buildings across the campuses. The map also includes satellite views and traditional two-dimensional street maps and offers overlays that display details such as dining locations and parking permit requirements, photos related to the buildings and videos linked to specific campus locations.

The maps are only accessible via the Plugin (no downloadable KML), and you can view the new map here on the Duke website. In addition, the map is fully functional on mobile devices.

Google Earth layers – NASA’s Earth Observation

NASA’s Earth Observation site dozens of layers of the global scientific data is formatted for viewing with Google Earth.

These are grouped into the ocean, atmosphere, energy, land, and the Life category. The layers are too many to list, but they include:

Sea surface temperature
Chlorophyll concentrations (MODIS)
Snow cover and sea ice extent
Cloud water content (MODIS)
Total precipitation (TRMM)
Water vapor (MODIS)
The temperature of the land surface
radiation
Active Fires (MODIS)
Land cover classification (MODIS)
permafrost
Vegetation index [NDVI] (MODIS)
The population density

The layers are highlighted in red above were combined into a single network link, which you can download the screenshot below. This will give you a preview of some of the available data. Visit NASA’s Earth Observing site other overlays the data.

How the Google Maps API limits affect your site

Several weeks ago we shared an update about the introduction of usage limits to the Google Maps API. Today I’d like to provide additional details about these limits, the types of sites that may be affected, and as promised, equip you with the means for measuring your site’s Maps API usage.

Usage limits and affected sites

Usage limits are being introduced to secure the long term future of the Maps API, while minimising the impact on developers. We have purposefully set the usage limits as high as possible – at 25,000 map loads per day – to minimise the number of affected developers, while ensuring that the service remains viable going forward. Based on current usage, only the top 0.35% of sites will be affected by these limits, meaning that the Google Maps API will remain free for the vast majority of sites.

We recognise that sites may occasionally experience spikes in traffic that cause them to exceed the daily usage limits for a short period of time. For example, a media site that uses a map to illustrate a breaking news story, or a map-based data visualization that goes viral across social networks, may start to generate higher traffic volumes. In order to accommodate such bursts in popularity, we will only enforce the usage limits on sites that exceed them for 90 consecutive days. Once that criteria is met, the limits will be enforced on the site from that point onwards, and all subsequent excess usage will cause the site to incur charges.

Please be aware that Maps API applications developed by non-profit organisations, applications deemed by Google to be in the public interest, and applications based in countries where we do not support Google Checkout transactions or offer Maps API Premier are exempt from these usage limits. We will publish a process by which sites can apply for an exemption on the basis of the above criteria prior to enforcement of the limits commencing. Non-profit organizations are also encouraged to apply for a Google Earth Outreach grant, which provides all the additional benefits of a full Maps API Premier license.

Evaluating API usage by your site

To help you measure your site’s Maps API usage, we have now added the Maps API to the Google APIs Console. The Google APIs Console is a centralised dashboard for Google’s developer offerings, and we encourage all developers, no matter how big or small your application, to create an APIs Console account.

We are initially introducing the limits for Maps API v2 and Maps API v3 map loads. The Maps Image APIs, and differentiated pricing and limits for Maps API v3 Styled Maps, are not currently included in the APIs Console, but will be added in the future. Once you’ve created an APIs Console account, please follow the instructions in the Maps API documentation to enable Maps API v2 or Maps API v3 on your APIs Console Project, and update your application to provide your APIs Console key when loading the Maps API.

After updating your Maps API application, you will begin to see your usage reported in the APIs Console.

Pacific Crossing in Google Earth

Join a journey of discovery virtually in Google Earth, as Liquid Robotics launches four wave-powered robotic gliders to cross the Pacific ocean in their Pacific Crossing (PacX) Challenge Expedition. The wave gliders are attempting to set a new world record for the longest distance ever attempted by an unmanned vehicle and will be collecting data about the Pacific ocean for use by scientists and students back on dry land. These R2D2s of the sea will cross 25,000 miles over 300 days and collect over 2 million data points, helping build the record of oceanic knowledge.

Wave glider robots await launch from San Francisco in this first expedition blog post in Google Earth.
To follow the wave gliders in Google Earth, download the expedition KML file or open the PacX Gallery page and click on the ship icon. You will be able to read updates from scientists sharing the latest robotic observations, from wave height in storms to weather measurements like barometric pressure, wind speed and air temperature. The ship icon will represent the location of the wave gliders, starting in the San Francisco bay.

Google Earth: Canada’s largest intact forest

In just three minutes, you can take a non-stop, coast-to-coast Google Earth narrated tour of Earth’s “green halo:” the boreal forest. The Pew Environment Group takes you over the vast northern forests and waterways and unveils an ecosystem that stores twice as much carbon per acre as tropical rainforests, holds more freshwater than any other continental-scale ecosystem and teems with wildlife. Watch the tour below or download the KML file to view in Google Earth.

The Pew Environment Group is the conservation arm of The Pew Charitable Trusts, a nongovernmental organization that works globally to protect our oceans, preserve wild lands and promote clean energy. Pew and its sister organization, the Canadian Boreal Initiative, developed this tour to illustrate the nature of the blue forest and its ability to store massive amounts of carbon, primarily in its soil and wetlands. The tour is featured at the launch of Google Earth Outreach in Canada, happening this week.

Viewers will see bears, wolves, and caribou that still roam this vast landscape, learn about aboriginal communities that depend on the boreal, view the Peace-Athabasca Delta, one of the most important wetlands in the world, and the last refuges for North American Atlantic salmon.

The Peace-Athabasca Delta viewed in the Pew Environmental Group’s new Google Earth tour.

Unfortunately, Canada’s boreal forest is increasingly affected by large-scale industrial activities. A rapidly expanding footprint of development already includes 180 million acres (728,000 km²) affected by forestry, road building, mining, oil and gas extraction, and hydropower.

Pew and CBI have worked with aboriginal communities, conservation groups, federal, provincial and territorial governments to protect the boreal, resulting in 185 million acres set aside from development to date, including key wetland and river areas. That total represents more than 12% of Canada’s 1.2 billion-acre (nearly 4.9 million km²) boreal forest.

Visit us online to learn more about the steps we can take together to protect this global treasure.
