Description: 坐标转换 从经纬度坐标到大地坐标
利用网络上开源的资料，可以很容易的实现从经纬度坐标向各种投影坐标的转换，美国地质调查局开发USGS的GCTP就是很好的东西-Coordinate transformation from the latitude and longitude coordinates into geodetic coordinates the use of open source information network can be very easy to achieve from the latitude and longitude coordinates to a variety of projection coordinates conversion, the United States Geological Survey USGS developed the GCTP is a very good thing

Description: ：World Wind是NASA发布的一个开放源代码的地理科普软件，由NASA Research开发，NASA Learning Technologies来发展，它是一个可视化地球仪，将NASA、USGS以及其它WMS服务商提供的图像通过一个三维的地球模型展现，还包含了火星和月球的展现。软件用C#编写，调用微软SQL Server影像库Terrain Server来进行全球地形三维显示。它通过将遥感影像与SRTM高程（航天飞机雷达拓扑测绘）叠加生成三维地形。-: World Wind is NASA released an open source geographic science software developed by the NASA Research, NASA Learning Technologies to develop, it is a visual globe, will be NASA, USGS and other WMS services provided by a three-dimensional image Earth model shows, also includes display of Mars and the moon. Software written using C#, call the Microsoft SQL Server Image Database Terrain Server to display the global three-dimensional terrain. It is through the elevation of remote sensing images and SRTM (Shuttle Radar Topology mapping) stack generate three-dimensional terrain.

Description: The purpose of this lab exercise is to introduce the student to geometric correction of digital imagery (see Figure A-
6, in appendix). The lab exercise involves the collection of two sets of reference points from the following sources:
(1) GPS receivers and (2) USGS 7.5 minute topographic maps. The reference points are collected in units of latitude
and longitude and will serve as the ground control points (GCP) and check points (CP). An input image of Blacksburg is matched to the reference coordinates collected above to reduce positional errors. This process is called image registration. -The purpose of this lab exercise is to introduce the student to geometric correction of digital imagery (see Figure A-
