Uuit1 What is Geomatics? （什么是测绘学）

Geomatics Defined（测绘学定义）

Where does the word Geomatics come from?（Geomatics－测绘或地球空间信息学，这个名词是怎么来的呢？）GEODESY+GEOINFORMATICS=GEOMATICS or GEO- for earth and – MATICS for mathematical or GEO- for Geoscience and -MATICS for informatics. （大地测量学＋地理信息学＝GEOMATICS 测绘学或者geo 代表地球，matics 代表数学，或者geo 代表地球科学，matics 代表信息学）It has been said that geomatics is many things to many people.（据说测绘学这个词对不同的人有不同的理解）The term geomatics emerged first in Canada and as an academic discipline; it has been introduced worldwide in a number of institutes of higher education during the past few years, mostly by renaming what was previously called “geodesy” or “surveying”, and by adding a number of computer scienceand/or GIS-oriented courses.（这个术语【term 术语】作为一个学科【academic discipline 学科】第一次形成【emerge】于加拿大；在过去的几年里被全世界的许多高等教育研究机构所熟知，通常是以前的“大地测量学” 或“测量学”在引入了许多计算机科学和GIS 方向【或“基于GIS” 】的课程后重新命名的。）Now the term includes the traditional surveying definition along with surveying steadily increased importance with the development of new technologies and the growing demand for a variety of spatially related types of information, particularly in measuring and monitoring our environment.（随着新技术的发展和不断增长的对空间关系的信息类型的需求，尤其是在测量和监测我们的环境方面【环境监测】，现在，传统测量学定义连同【along with】日益【steadily 稳定的】增长的测量的重要性一起包含在这个术语里了。【逗号后面的句子修饰demand】）Increasingly critical are areas of expanding populations, appreciating land values, dwindling natural resources, and the continuing stressing of the quality of our land, water and air from human activities. （日益增长的危机来自人口扩张，地价上涨，资源紧缩【紧张】，还有由于人类活动引起的土地、水、空气质量的持续的压力【由人类活动带来的土地、水、空气质量的恶化】As such, geomatics bridges wide arcs from the geosciences through various engineering sciences and computer sciences to spatial planning, land development and the environmental sciences.（这样，测绘学在地球科学，各种工程学【engineering sciences 工程学】，计算机科学，空间规划，土地开发和环境科学相互之间架起了广泛的桥梁。）Now the word geomatics has been adopted by several international bodies including the International Standards Organization(ISO),so it is here to stay.（现在geomatics 这个词已经被包括ISO【国际标准化组织】在内的数个国际机构【international bodies】所采用，因此它就这样被普遍接受【be here to stay 习惯用语“被普遍接受” 】The term “surveyor” is traditionally used to collectively describe those engaged in the above activities. （surveyor 这个词按惯例用来总指（这换成“总称”较好）【collectively 全体的】那些从事上述活动的人。）More explicit job descriptions such as Land Surveyor, Engineering Surveyor or Hydrographic Surveyor for example, are commonly used by practitioners to more clearly describe and market their specialized expertise. （更具体的【explicit 清楚的、直接的】工作如土地测量员、工程测量员和水道测量员，【commonly 一般一般地】被业内人士【practitioners 从业者】用来更准确的描述他们的专门技术。【直译为：更清楚的工作描述就如如土地测量员、工程测量员和水道测量员，一般被从业者用来更准确的描述他们的专门技术。）】The term geomatics is a recent creation to convey the true collective and scientific nature of these related activities and has the flexibility to allow for the incorporation of
