If there isn’t enough new snow-fall over the accumulation zone during thewinter or if too much snow consistentlymelts from that upper-most area duringthe summer, the glacier has crossed acritical threshold and is usually doomedto disappearance.

  • 5 Automating the Process “With some glaciers disappearing in the study areas and others remaining stable, Dr. Pelto’s Planet Action project confirmed the importance of monitoring the ice masses individually,” said Spot Image’s de Chassy. It also verified that disappearance indicators can be found in multi-temporal Spot scenes. Pelto says the next step is to automate the glacier monitoring process. Automated change detection algorithms can be written to continually monitor Spot scenes over mountainous regions to pinpoint emerging outcrops and thinning upper margins. Once enough disappearing glaciers have been studied, scientists will be able not only to identify those with no future, but also to forecast how long until they’re gone. This will be a crucial advantage for areas that depend on glaciers for fresh water. “For glacier disappearance, we’ll make water management decisions 20-30 years out,” said Pelto. Currently, temperate alpine glaciers in the Andes, European Alps, Himalayas, Norway, Iceland, Western Canada and the U.S. Pacific Northwest supply fresh water to drainage basins at lower elevations. In these areas, glaciers provide vital summer run-off that supplies up to 30 percent of river water upon which fish hatcheries, agricultural irrigation, hydroelectric power plants and drinking water reservoirs depend. Knowing a decade or more in advance that a third of the water supply will disap- pear will give these areas significant advantages to take management steps that will F ig u r e 5 .

  • tricity, mainly through large dams. One key advantage of hydropower over other types of “intermittent” renewable energy is its ability to store energy and therefore to manage peak load demand. However, one major drawback of large dam infra- structures is often their large impact on the environment (creation of large flooding areas, damaging of ecosystems, fragmentation of wildlife habitat), and on local communities (displacement of population). This makes the construction of some dams a very controversial issue, as stakeholders have begun to question whether their positive effects (electricity, availability of water, control of floods) outweigh their negative social and envi- ronmental impacts. To address this question, it is impor- tant to assess the environmental impact (negative and positive) of large hydro- power infrastructures, not only prior to the construction of the dam (to get a building permit), but also after construction on a continuing basis. In this context, a pilot project has been set up at the Cana Brava hydro- power plant in Brazil, in partnership with international industrial groups, such as GDF SUEZ, Tractebel Engi- neering, and Tractebel Energia, to explore how EO-based SD indicators can help to assess the cumulative envi- ronmental impact of the dam.

EO pilot projects focusing on the private sector and addressing some of the key themes of SD, such as the sustainable exploitation of energy and natural resources, have highlighted the value and limitations of EO data to objectively assess changes in the envi- ronment and the cumulative footprint of global business activities. These projects provide stakeholders with rapid “third party” checks on sustainability of operations, even in the most remote or difficult-to-access regions. They also help SD managers to opti- mize resources and deployment of in-situ surveys by identifying “hot-spots” of change, where more detailed information is needed. Also, the consistency in time and space of EO data, associated with a transparent processing, offers a useful guarantee of quality of the data, which is critically needed as stakeholders (some- times with diverging interests) across the globe can have different views on the posi- tive or negative impact of business activi- ties.

  • requirements, requirements to products, products to observations, and all of these to system components. By introducing this simple but very flexible data model of “knots” and “links,” the construction and analysis of value chains, networks of value chains, dependency networks, and so on, are possible. The URR helps connect the processes, individuals, and dependencies that support decision making through Earth observations. The system performance specifications allow the matching of the user- and system- related components against each other to facilitate a gap analysis. In the next stage of URR development, algorithms for gap analysis will be added to the registry, and 5 the output of these algorithms can provide a basis for informing decisions on GEOSS SS Figure 5 .

Linking GEOSS to the Users As a user-driven system, GEOSS 6 needs to engage users. The URR is designed to be one of the key entry points for user engagement. GEO is discussing a registration system for users of GEOSS. Most likely, the registration will be global and scalable, so that any user can register in any of the GEOSS components and is then known globally in GEOSS. Combining this registration system with the URR will open many new opportunities for social and expert networking, which will further increase the versatility of the URR. The best way to test the URR is by entering information. Thus, users can assist in the further development of the URR in two ways: (1) by publishing infor- mation in the various URR forms; and (2) by providing comments on the overall URR design and logic flow. A comments field is available on each URR form to provide feedback on individual entries and a questionnaire is available online to provide more overall comments. The potential of GEOSS is signifi- SS Figure 6 . The URR provides forms to publish user-related information (blue boxes) and cant for supporting sustainability and vocabulary (green).

Either way, the next year will prove to be a crucial time for RapidEye as it intensifies marketing efforts through every channel to get noticed, builds its brand recognition, and continues to demonstrate the quality and reliability of its products and services to generate a broader customer base.

  • an obstacle or two. More than likely, RapidEye’s largest imagery project to date would be described by the team that executed and delivered it as a great success preceded by a series of challenges. The Ministry of Land and Resources (MLR) for the People’s Republic of China has been utilizing remote sensing and satellite imagery to map and monitor their country for over ten years. For a ministry overseeing a country with a land mass stretching 9.6 million km², it would surprise no one that the MLR had never been able to acquire imagery of the entire area within one year. They were looking for a system that could deliver, and RapidEye nego- tiated through their Chinese distributor Beijing Earth Observation (BEO) to be able to take on the project. RapidEye’s Head of Operations would tell you that the challenges of taking on a task of that magnitude were not even apparent when the contract was signed to cover China. The contract was renegotiated over a matter of months, and eventually stipulated that the MLR wanted 80% of China (7.8 million km²) delivered within a 6-month time frame with a maximum of 10% cloud cover. Of course there were also specific areas that the MLR needed absolutely cloud free. For a satellite imagery and solutions company that had been commercially operational for only six months when the project began, this requirement can be described only as an ambitious under- F ig u r e 2 .

Getting the low data, which RapidEye hadn’t dealt with 40% of their requested area, and by the or no cloud covered image of an area that needed to be obtained occasionally 3 required three, four or even five passes to capture an acceptable image. As one would suspect with the preceding statistics about the RapidEye system delivery, the project exceeded everyone’s expectations (including those of the team that created the initial collection plan). One month before the end of the collection window, the MLR had received 99.8% of their requested area with an average cloud cover of less than 6%. The Ministry of Land and Resources was suitably impressed by the RapidEye collection and delivery approach and will find themselves over the next months deciding whether it is necessary and within their budget to repeat the project. If so, RapidEye expects to be at the top of the list of considered providers, hoping that having completed the collection of China so well the first time will make them a shoo-in for round two. Making a Difference Early in the morning of Saturday, February 27, 2010, an earthquake and resulting tsunami hit the western coast of South America. With the epicenter south of the capital of Santiago, Chile, the quake measured 8.8 on the moment magnitude scale (MMS), causing the deaths of over 530 people near the epicenter, which included the town of Concepción. Knowing that this would prove to be a large natural disaster and that rescue, at this early stage. Luckily, the team end of the third month, over 75% of the recovery and future rebuilding efforts worked diligently to solve these steps imagery had been collected (5.85 million could benefit from the use of RapidEye’s in the delivery process, and an in-house km²).
