Post-tornado mapping in Google Maps and Earth

This past week, several devastating tornadoes struck across a wide swathe of the southern United States. Our Crisis Response team is activating to provide data and imagery we hope will be useful to first responders and the general public.

In cooperation with our satellite partner GeoEye, we have imagery of the aftermath of several tornadoes, including in Tuscaloosa, Alabama as shown below. We have created several before-and-after comparisons in a Picasa album.

Left: Google imagery from late 2010. Right: GeoEye imagery from Thursday, April 28.

Top: Charleston Square Apartments, Tuscaloosa, Alabama. Bottom: Towns of Pleasant Grove, Concord, and Hueytown, Jefferson County, Alabama. Click to see enlarged.

This imagery, as well as data sets such as Red Cross shelter locations and tornado touchdown reports, are available in this collection on Google Maps. We will continue to add imagery and data as it comes available.

Our heart goes out to everyone affected by this tragic event.

Update: You can now access the satellite imagery directly in Google Earth. Make sure the Places layer is enabled, then go to Alabama. Click the image of a tornado to find links to load the images.

Haiti, one year after the earthquake

[Cross-posted from the Official Google Blog]

It’s been one year since the 7.0 magnitude earthquake struck Haiti, and governments and NGOs are continuing to respond, many using high-resolution images of the area. To support these efforts, we’ve updated our aerial imagery in Google Earth of the Port-au-Prince area to include images from before and after the earthquake, as well as made updates throughout 2010. These pictures provide an evolving view of the movement of people, supplies and rubble.

To access this imagery directly, use the Historical Imagery feature of Google Earth.

Complementing our online efforts with this imagery, a webpage and crisis response tools such as Person Finder, Google has made an effort to contribute to relief in Haiti by providing technical and financial support to NGOs. These organizations such as Doctors Without Borders and Partners in Health and specific technology NGOs such as Samasource and Frontline SMS continue to help the Haitian people. We’ve looked to them to help us guide our ongoing response to this crisis.

In November, we gathered updated aerial imagery, and sent a second wave of Google teams to Haiti to evaluate our earlier response efforts and see where Google could continue to provide help. We met with local Haitians and technology NGOs under tents, in trailers, in Internet cafes and at restaurants.

From these visits we witnessed the difficulty involved in using our mapping tools under the unpredictable nature of the Internet in Haiti, and so have focused on developing better offline capabilities and have proposed ideas for improving overall Internet access in Haiti. We also ran training for aid workers on our collaborative tools like Google Apps, which can help coordinate resources. While there, we spent time understanding how NGOs are combating the cholera epidemic, and brainstorming tools that could help aid workers produce specialized maps of epidemic case data and chlorination levels at water points, which are critical for planning and prevention.

If you’re interested in helping with Google’s efforts in Haiti, you can:

• Support our open source Crisis Response projects such as Person Finder or attend conferences like the Random Hacks of Kindness.
• Volunteer with NGOs working on Crisis Response technology such as Crisis Commons and Ushahidi.

Our experience and the updated imagery demonstrate that there are still significant needs on the ground in Haiti. We’re continuing our efforts to support locals and NGOs and look forward to seeing how technology will continue to help both Haitians and victims of disasters worldwide.

Mission Blue: Return to the Gulf of Mexico

With support from Google, the Waitt Foundation, Hope Spots LLC and the National Geographic Society, Sylvia Earle and Mission Blue are embarking on an expedition to the Gulf of Mexico that will take a deep look at how the region is recovering from the five million gallons of oil spilled from the BP Deep Horizon Oil Spill last year. Follow along with the expedition by checking back daily and clicking on the blue ship icon in Google Earth located off of the US coast near Pensacola, Florida, where the expedition begins (make sure the Places layer is turned on). The science team will share updates and media from the expedition, including photographs, videos and links to Google maps on the National Geographic News Watch blog here.

Click on the blue ship icon near Pensacola, Florida in Google Earth
to see the most recent post from the expedition.

"Our goal is to identify areas with potential for Gulf ecosystem recovery," said Dr. Earle, founder of SEAlliance and recipient of the 2009 TED Prize that developed into Mission Blue, an international ocean conservation movement. "That is going to require protection of places healthy enough to replenish and rebuild populations. What’s happened here is far from over for the clams and oysters and other sea life critical to a healthy Gulf of Mexico."

The fate and impact of the spilled oil, gas and dispersants applied following the blowout into the Gulf are the subject of intense discussion by experts. The expedition team, assembled under the broad banner of the Mission Blue initiative, seeks answers to questions about the current status of key species and ecosystems.

Other research participants include: Dr. Thomas Shirley, Larry McKinney, Douglas Weaver and Harriet Nash from the Harte Research Institute at Texas A&M University-Corpus Christi; Edith Widder and Brandy Nelson, Ocean Research & Conservation Association and Carl Safina, Blue Ocean Institute. Research dives are planned using a Dual Deepworker submersible made available to the expedition by the Waitt Institute.

You can also experience the expedition for yourself by downloading this KML for viewing in Google Earth.

Earthquake motivates New Zealanders to model their town

Last week, local volunteers in Christchurch and Dunedin New Zealand invested a day of their time learning how to create 3D models using Google SketchUp. The workshops focused on learning how to geo-model, a process that involves creating 3D models of buildings from photographs for display in Google Earth.

The workshop was led by local architect and geo-technology expert Jason Mill of ZNO, who was inspired to organize the events following the recent earthquake in his hometown of Christchurch. As an architect, Jason recognized the value of having a publicly accessible digital model of the city, and has invested considerable time over several years modeling the central business district of Christchurch.

The value of these models took on new meaning when many of the heritage buildings in town disappeared, leaving the community to decide what should stand in their place.

Five hours away, the city of Dunedin was unaffected by the earthquake, but given its large number of heritage buildings, local residents there decided that it shouldn’t assume that they will be there forever. They suddenly felt a greater sense of urgency around creating a historical record of these buildings.


Historic preservation and city planning are two reasons that many people model their town, but there are numerous other benefits. Local business owners are keen to be represented on the 3D map, enabling virtual tourists another means to locate them on the Internet. Downtown organizations responsible for promoting their city are other beneficiaries. Exploring a destination virtually, whether for business or leisure, is becoming as common as reading a web site.

Google supports these workshops because it aligns with our mission to build a comprehensive atlas of the world online. This atlas is a dynamic, collaborative, open platform for visualizing, sharing, and searching geographic information—whether it’s in your local neighborhood or on the other side of the globe.

By providing free authoring tools like SketchUp and Building Maker, we’re making it easy to introduce 3D buildings to the map. Maps are no longer just 2D static images on paper, they’re living reflections of the local world around us. Everyone has the ability to help shape the map and contribute their local knowledge, experiences and points of view. Adding 3D buildings to the map is just one way to achieve that.

Local residents such as those in Christchurch and Dunedin are doing more than just putting their cities on the map, they’re contributing to an atlas of the world, and becoming the curators of the special places that their cities have to offer.

Google Map Maker and UNITAR Collaboration Shines at Shanghai World Expo

This past weekend at the 2010 World Expo, UN Institute for Training and Research (UNITAR) and Google gave a joint presentation and informational session about their recent work together in global humanitarian mapping.

Illustrating his remarks with information about the Pakistan 2010 flood relief efforts, UNITAR Geospatial Analyst Josh Lyons explained how Google Map Maker helps his organization quickly and accurately produce geospatial products and emergency response maps. By leveraging the high quality, up-to-date information provided by users in Google Map Maker, UNITAR is able to produce and distribute helpful composite map products using tools such as UNITAR’S Operational Satellite Applications Programme (UNOSAT). These products played a key role in facilitating modern humanitarian relief for the recent disaster in Pakistan.

UNITAR/UNOSAT map for Pakistan flood analysis, with transport data from Google Map Maker

Dr. Carlos Lopes, United Nations Assistant Secretary-General and Executive Director of UNITAR, expressed his excitement both to work with Google and that UNITAR/UNOSAT resources that had previously been spent on mapping data collection could now be invested directly into analysis. He remarked that users and beneficiaries aided by this collaborative effort include operational UN agencies, international NGOs and national entities from government and civil societies, and of course, the people directly affected by disasters and other crises.

We hope that the interest and increased awareness that the Shanghai World Expo event generated about Google Map Maker helps to build an even stronger user community. It’s the online mapping contributions of volunteers across the globe that enable Map Maker to be a valuable tool for humanitarian activities like this as well as a source of quality maps in the developing world. Let’s continue mapping the world together!

Imagery of Four Mile Canyon fire in Boulder, CO

This Labor day brought Colorado its most destructive wildfire to date, as measured in structures lost. 169 homes were destroyed and 6,181 acres of mountain terrain were scorched as the Four Mile Canyon fire blazed its way through our hillside.

Community members worked together to create a collaborative map to show the location of the fire and track its progress. The map was open for anyone to contribute information as soon as it became available. For many, this was a primary source for the most up-to-date information available about the fire.

Additionally, new imagery from GeoEye of the burn area is now available as a KML overlay. We will be adding this to our base layer soon. When viewed in 3D using Google Earth, this image vividly illustrates the extent and magnitude of the damage.

Our profound gratitude goes to the fire fighters who worked tirelessly to subdue the fire in the face of high winds and difficult terrain. If you would like to help, you can learn more here.

New imagery of the San Bruno fire

One of the most common requests we get from users--literally thousands of times each month--is that we update or improve the imagery of a certain location in Google Earth and Maps. In order to provide the freshest, highest quality data possible, we partner with different organizations such as GeoEye, Spot Image, Infoterra, DigitalGlobe, the USDA, as well as national, city and county governments. At times we also collect our own imagery using planes equipped with aerial mapping cameras.

We collect imagery to improve overall quality--especially when we want to refresh data very quickly, for example after disasters, to complement data provided by our partners. To date we’ve collected imagery in the U.S. and in Haiti following the earthquake. This past Saturday we collected imagery over the parts of San Bruno devastated by last week’s terrible gas explosion. Google's data and tools are used by many government and non-governmental organizations to assist in post-disaster recovery, as well of course by our millions of users. This San Bruno imagery is now live in Google Earth through a KML overlay link and will be part of the base layer soon.

We are committed to providing the most accurate and up-to-date data in our maps at all times and especially in post-disaster situations.

Responding to the fires in San Bruno

Update at 6:27pm: We now have updated satellite imagery (from GeoEye) of the area. You can download it here and view it in Google Earth.

Like many friends in the Bay Area and across the country, I’ve been stunned by the images of raging fires in San Bruno. Nearly 40 structures have been destroyed and 120 damaged, with several fatalities and multiple injuries after the explosion of a gas line. More than 100 people have been evacuated to nearby shelters.

This disaster strikes close to home; our YouTube offices are about two miles away from the main gas explosion. We’re thankful that no Google employee was hurt, but remain concerned for the well-being of our neighbors in the area.

We are donating an initial amount of $50,000 to the American Red Cross Bay Area Chapter to help with relief efforts. We’re directing Googlers to the local blood drives today and will be hosting blood drives in our San Bruno, Mountain View and San Francisco offices early next week.

We’ve created this map to show the location of the explosion and highlight nearby shelters and resources. The map is open for collaboration and welcomes additional useful information. We encourage you to embed it in your website or blog. We are also exploring the possibility of obtaining updated imagery of the area to help responders visualize the scope of the disaster.

Remembering Hurricane Katrina

Before coming to Google, I worked at a non-profit organization that responded to Hurricane Katrina by sending mobile health clinics to the Gulf Coast, where there was critical shortage of medical and mental health care providers. I traveled through the region regularly for nearly two years following the storm and each time I would visit the same spots, trying to get a sense of how they were recovering. In some places I saw rapid change and in others hardly any.

Since moving to California I haven’t been able to get back to the Gulf, but I think about that time often. I was excited back in 2008 when we made Street View imagery of New Orleans available, and I’ve kept track of updates to our overhead imagery of the area in Google Earth and Maps.

With the fifth anniversary of Hurricane Katrina approaching, my mind has been with the hardworking and resilient residents of coastal Louisiana and Mississippi. I used the Historical Imagery feature in Google Earth to look back at some of the places I used to visit, and created these slideshows to show the change over time.

These by-now-familiar images of the Lower Ninth Ward are no less heartbreaking today than they were when we first saw them.



The Biloxi Bay Bridge, which connects Biloxi to Ocean Springs, MS, was heavily damaged in the hurricane and had to be rebuilt. The new bridge opened to traffic in November, 2007.

Seeking map data in response to Pakistan floods

According to the UN, the recent floods in Pakistan have affected over 4 million individuals - and the human toll continues to grow. Disease is an ever-increasing risk as relief agencies rush to the aid of those who have been hurt or displaced.

Google’s Crisis Response team has provided satellite imagery and KML layers to assist relief efforts in past disasters, including the Haiti earthquake and recent Gulf of Mexico oil spill. In Pakistan, however, the cloud cover over the impacted areas has inhibited our ability to make this valuable content available. The Crisis Response team is looking to collect and aggregate imagery and user generated KML, or other map data, with the goal of making this content more accessible to both crisis responders and the general public. We’re hoping you can help. You can submit links to KML and map data via the following form. We’ll contact you if we are able to publish your content.

Further, we’ve released a version of our Person Finder tool in Urdu. We realize many of the victims of this disaster lack any connectivity to the Internet, but remain hopeful that tools like this can assist the diaspora and general disaster community in collecting and dispersing information on the well-being of those impacted.



Your data might help relief efforts; we appreciate you sharing it with the world.

Map Makers respond to the Pakistan landslides

In January 2010, a series of landslides hit Atta Abad, in the Gilgit-Baltistan semi-autonomous region of Pakistan, causing loss of lives and blocking the Hunza River. Since then, the region and its 500,000 people are under continual threat from the rising height of the lake formed due to the landslide. Lake waters have already displaced about 20,000 residents; some villages are completely submerged while downstream communities are at risk from flood waves.

This event took the work of Omer Sheikh and Jabran Rafique -- dedicated individuals, exceptional Google Map Maker users & advocates -- to another level.

Omer currently lives in Lahore while Jabran resides in London. They live thousands of kilometers apart but have a shared commitment to map their country and assist their people as they cope with this disaster situation.

“From the onset of the disaster, the international community seemed to be hardly aware of the situation. Worst...I was unable to locate on a map where Atta Abad was! As a mapper, my first appeal went out to the Google Map Maker team, and Google Maps Pakistan,” recalled Omer.

Together, Jabran and Omer created a website, http://www.local.com.pk/hunza/, that uses the Map Maker API -- for raising awareness about the importance of this emergency and making disaster data more accessible and useful. The publishing of post-disaster imagery, made available by Google, is also allowing Map Maker users to provide unique mapping contributions (i.e. shelters, health centers, flood prone areas, etc), all to be brought online in near-realtime. The website is now recognized as a primary source of information for the Hunza disaster, and as such is being listed on the UN-Spider knowledge portal.

Jabran describes their mapping process: “The gap in information available to the public was obvious. After getting the latest imagery, we started mapping the area. We used Map Maker as our baseline data and started adding other feature of interested such as locations of towns, the extent of the lake, submerged bridges & highway sections.”

When asked about his motivations for becoming so involved in this effort, Omer explains: “We hope that our effort to make reliable information more widely available will help disaster relief managers and decision makers save lives and prevent more damage to the fragile economy of this remote region. In contributing to Map Maker, my desire is to establish a basic framework around which we can document, understand and bring transparency to the events taking place around me. We, as a mapping community, need to better demonstrate the benefits of online collaboration and the utility of tools such as Map Maker for rapid dissemination of information.”

This is the journey of two mappers who have used the Map Maker community as a basis to connect the ideas & skills of dedicated individuals -- for the better good of their own community. To contribute to the Hunza Landslide Relief Support please visit this website.

Keeping up-to-date on the Gulf of Mexico oil spill

[Cross-posted with the Official Google Blog]

It is estimated that at least 6 million gallons of oil have leaked into the Gulf of Mexico since the Deepwater Horizon explosion a month ago. Cleanup efforts are underway, but the oil has spread extensively around the Gulf and along the southern U.S. coastline. Oil has begun washing up on the beaches of Louisiana and the delicate wetlands along the Mississippi River, and can spread to Florida and throughout the Gulf as weather conditions change. This sequence of images, coming from NASA’s MODIS satellites, illustrates the movement and growth of the oil slick over the past few weeks:

April 25, 2010

April 29, 2010

May 9, 2010

The last image, taken earlier this week (on May 17), shows the coastal areas currently at risk from the spreading oil, and can help those working on the wide range of relief efforts.


You can view this and other MODIS imagery in Google Earth by downloading this KML. You can also view additional imagery and find other resources and news at our oil spill crisis response page.

Imagery for Qinghai, China earthquake

On Tuesday, April 13, a powerful 6.9 earthquake shook the province of Qinghai, China, resulting in widespread destruction and the loss of more than 1,700 lives. Working closely with GeoEye, we’ve been able to acquire some high resolution post-earthquake imagery, which vividly illustrates the magnitude of this tragic event.

(click image to view full-size; click here to view in Google Earth)

To see more of this imagery, you can download the KML here and open it in Google Earth.

In addition, an international team, including many of our Chinese Googlers, have worked to create a Crisis Response page for the earthquake with several additional resources:

• The China Person Finder tool, which can be used to submit or search for information about individuals who may have been affected. It is available in Simplified Chinese, Traditional Chinese and English, and is accessible on mobile. We encourage organizations and media sites to embed the gadget on their sites and help spread the word.
• Google News and real-time search, which features posts to Twitter and other sources. This provides the latest information from authoritative sources and people on the ground.
• A My Map to help users contribute data about Qinghai, such as the conditions in specific areas and rescue efforts underway.

The Chinese version of this page can be accessed from a link on our homepages on google.com.hk and google.com.tw, and we will continue to update the pages as more materials become available.
