案 追蹤 如果說定位是一個不斷確定物體所處位置的過程，那么追蹤則是一個監(jiān)控移動物體的過程。 貿(mào)易依賴于運輸系統(tǒng)將貨物和服務(wù)運輸?shù)匠鞘械母鱾�角落以及全國各地。因此有效的物流管理至少要做到：告訴顧客包裹已經(jīng)運到，調(diào)度大巴車泊車時間以維持最佳的服務(wù)程序，指揮最近的救護車趕到現(xiàn)場，幫助油輪避開危險。 GPS用于聯(lián)結(jié)通訊鏈和電腦，為農(nóng)業(yè)，大規(guī)模transit，城市運輸，公共安全，船舶汽車跟蹤提供了系統(tǒng)骨架。所以警察，救護車和火警部門都接受了像trimble的基于GPS的車輛定位系統(tǒng)，這沒什么奇怪的。他能夠在一張計算機地圖上精確定位重大事故的位置和最近的應(yīng)急車輛位置。有了這么詳細(xì)的，形象的圖像信息，調(diào)度員可以迅速，自信地作出反應(yīng)。 芝加哥開發(fā)了一種GPS追蹤系統(tǒng)，用于監(jiān)控特勤車輛在街道的位置，從而節(jié)省了回應(yīng)991呼叫的寶貴時間。在商業(yè)前沿，澳大利亞的兩家出租車公司通過這種系統(tǒng)來追蹤他們的出租車已獲得更多的利潤并提高安全性。 地圖 它們都在哪里？ 世界如此之大，各方面對地圖的需求又是如此迫切，應(yīng)用GPS去測量和繪制地圖將會節(jié)省大量的時間和金錢。今天,trimble GPS使一個測繪員就能夠在一天之內(nèi)完成過去一只隊伍需要數(shù)個星期才能完成的任務(wù)。并且它們能夠在一個更精確的層次上完成任務(wù)。 trimble在這一技術(shù)上領(lǐng)先，現(xiàn)在它已經(jīng)成為實現(xiàn)測繪控制的首選，其在測繪上所取得的成效也是可觀的。 我們已經(jīng)見識了GPS對定點定位，道路定位，車隊定位的能力。繪圖已經(jīng)成為一門藝術(shù)一門科學(xué)：首先用GPS定位物體，生成地圖或世界上所有物體的模型。我們將標(biāo)注一切：山脈，河流，森林和其它的地形。道路，街道，城市街道。無害動物，珍貴的礦藏和所有的資源。自然災(zāi)害，事故，交通意外和考古遺跡。 GPS正在繪制世界之圖。 Tracking If navigation is the process of getting something from one location to another, then tracking is the process of monitoring it as it moves along. Commerce relies on fleets of vehicles to deliver goods and services either across a crowded city or through nationwide corridors. So, effective fleet management has direct bottom-line implications, such as telling a customer when a package will arrive, spacing buses for the best scheduled service, directing the nearest ambulance to an accident, or helping tankers avoid hazards. GPS used in conjunction with communication links and computers can provide the backbone for systems tailored to applications in agriculture, mass transit, urban delivery, public safety, and vessel and vehicle tracking. So it's no surprise that police, ambulance, and fire departments are adopting systems like Trimble's GPS-based AVL (Automatic Vehicle Location) Manager to pinpoint both the location of the emergency and the location of the nearest response vehicle on a computer map. With this kind of clear visual picture of the situation, dispatchers can react immediately and confidently. Chicago developed a GPS tracking system to monitor emergency vehicles through their streets, saving precious time responding to 911 calls. And on the commercial front, two taxi companies in Australia track their cabs for better profit and improved safety. Mapping "Where is everything else?" It's a big world out there, and using GPS to survey and map it precisely saves time and money in this most stringent of all applications. Today, Trimble GPS makes it possible for a single surveyor to accomplish in a day what used to take weeks with an entire team. And they can do their work with a higher level of accuracy than ever before. Trimble pioneered the technology which is now the method of choice for performing control surveys, and the effect on surveying in general has been considerable. We've seen how GPS pinpoints a position, a route, and a fleet of vehicles. Mapping is the art and science of using GPS to locate items, then create maps and models of everything in the world. And we do mean everything. Mountains, rivers, forests and other landforms. Roads, routes, and city streets. Endangered animals, precious minerals and all sorts of resources. Damage and disasters, trash and archeological treasures. GPS is mapping the world.
