题目内容
根据国家测绘地理信息局与××省测绘地理信息局要求，计划建设“××省地理信息公共服务平台”。平台基于面向服务的架构(SOA)，由分布式节点组成。各节点由在线地理信息数据、在线地理信息服务系统和运行支持系统组成。 (1)在线地理信息数据构成。 利用现有数据资源(包括矢量数据、影像数据、模型数据、地理监测数据、实时传感数据)，按照地理信息公共服务平台相关数据规范，经整合处理后，形成在线地理信息数据(包括地理实体数据、地名地址数据、电子地图数据)。 (2)地理实体数据处理要求。 地理实体数据是对地理实体的描述与表达，采用实体化数据模型，以地理要素为空间数据表达与分类分层组织的基本单元。地理实体数据遵循的技术标准是《地理信息公共服务平台地理实体与地名地址数据规范》(CH/Z 9010—2011)。 (3)地名地址数据处理要求。 地名地址数据是以地理位置标志点来表达地名与地址的数据，包含结构化地名地址描述、地名地址代码等信息。地名地址数据遵循的技术标准是《地理信息公共服务平台地理实体与地名地址数据规范》(CH/Z 9010—2011)。 (4)电子地图数据处理要求。 电子地图数据是针对在线浏览和标注的需要，以各类数据源为基础，经过内容选取组合、符号化表达、图面整饰后形成的各类视屏显示地图。电子地图数据遵循的技术标准是《地理信息公共服务平台 电子地图数据规范》(CH/Z 9011—2011)。 问题： 在电子地图数据生产过程中，地图分级时每级要素内容选取应遵循哪些原则

Thanks to the GPS, the apps on your phone have long been able to determine your general location. But what if they could do so with enough precision that a supermarket, say, could tempt you with digital coupons depending on whether you were hovering near the white bread or the bagels It may sound far-fetched, but there’s a good chance the technology is already built into your iPhone or Android device. All it takes for retailers to tap into it are small, inexpensive transmitters called beacons. Here’s how it works: using Bluetooth technology, handsets can pinpoint their position to within as little as 2cm by receiving signals from the beacons stores install. Apple’s version of the concept is called iBeacon; it’s in use at its own stores and is being tested by Macy’s, American Eagle, Safeway, the National Football League and Major League Baseball. Companies can then use your location to pelt (连续攻击) you with special offers or simply monitor your movements. But just as with GPS, they won’t see you unless you’ve installed their apps and granted them access. By melding your physical position with facts they’ve already collected about you from rewards programs, brick-and-mortar businesses can finally get the potentially profitable insight into your shopping habits that online merchants now take for granted. The possibilities go beyond coupons. PayPal is readying a beacon that will let consumers pay for goods without swiping a card or removing a phone from their pocket. Doug Thompson of industry site Beekn.net predicts the technology will become an everyday reality by year’s end. But don’t look for stores or venues to call attention to the devices. "People won’t know these beacons are there," he says. "They’ll just know their app has suddenly become smarter." The GPS on your phone can ______.
Directions: Read the following text. Choose the best word(s) for each numbered blank and mark A, B, C or D on the ANSWER SHEET. It sounds like a real-life version of Lost: a 272-ton Boeing 777 1 from Kuala Lumpur International Airport and 2 less than an hour into a flight to Beijing, disappearing from air-craft radar screens and triggering a massive search 3 high-tech warships, nimble supersonic jets, all-seeing satellites—the combined technological resources of 26 countries. Days 4 without a trace of the airliner. Big Brother looks high and low—and finds 5 . The world lost 6 with Malaysia Airlines Flight 370 in the early hours of March 8, somewhere in no-man’s-sky 7 Malaysia and Vietnam. Every day that followed brought new theories of what might have happened as dark turned to dawn. Was the plane hijacked to some remote landing strip and, if so, where are the passengers 8 had the jet malfunctioned and 9 into the ocean-and if so, where was the debris As search team looked for answers to these questions, the millions of people worldwide who were 10 for updates about MH370 were left wondering how, in 2014, technology could come up so short, 11 a 209-ft. (64m) airliner carrying 239 people to 12 for the longest period of time in modern commercial aviation history. The 13 story of MH370 doesn’t fit into the narrative of our omniscient (无所不知的) era. The world’s intelligence agencies can watch and 14 to millions of us as we go about our lives. 15 we nonspies have plenty of tracking technology at our disposal.

How, then, with our 17 infrastructure of bits and bytes, did we fail to 18 a jumbo jet The answers are disturbing. For all the post-9/11 security protocols we submit to every time we get on a plane, much of the basic 19 that is meant to track our progress through the sky is full of holes. And even our most modern 20 can be rendered invisible by the human hand.
In the past 35 years, hundreds of millions of Chinese have found productive, if often exhausting, work in the country’s growing cities. This extraordinary mobilization of labour is the biggest economic event of the past half-century. The world has seen nothing on such scale before. Will it see anything like it again The answer lies across the Himalayas in India. India is an ancient civilization but a youthful country. Its working-age population is rising by about 12m people a year, even as China’s shrank last year by 3m. Within a decade India will have the biggest potential workforce in the world. Optimists look forward to a bumper "demographic dividend", the result of more workers per dependant and more saving out of income. This combination accounted for perhaps a third of the East Asian miracle. India "has time on its side, literally," boasted one prominent politician, Kamal Nath, in a 2008 book entitled "India’s Century". But although India’s dreamers have faith in its youth, the country’s youngest have growing reason to doubt India. The economy raised aspirations that it has subsequently failed to meet. From 2005 to 2007 it grew by about 9% a year. In 2010 it even grew faster than China (if the two economies are measured consistently). But growth has since halved. India’s impressive savings rate, the other side of the demographic dividend, has also slipped. Worryingly, a growing share of household saving is bypassing the financial system altogether, seeking refuge from inflation in gold, bricks and mortar. The last time a Congress-led government liberalized the economy in earnest—in 1991—over 40% of today’s Indians had yet to be born. Their anxieties must seem remote to India’s elderly politicians. The average age of cabinet minister is 65. The country has never had a prime minister born in independent India. One man who might buck that trend, Rahul Gandhi, is the son, grandson and the great-grandson of former prime ministers. India is run by gerontocrats (老年统治者) and epigones (子孙): grey hairs and groomed heirs. The apparent indifference of the police to the way young women in particular are treated has underlined the way that old India fails to protect new India. China is mentioned in order to ______.
