    • An image-based georeferencing system comprises an image receiver, an image identification processor, a reference feature determiner, and a feature locator. The image receiver is configured for receiving a first image for use in georeferencing. The image comprises digital image information. The system includes a communicative coupling to a georeferenced images database of images. The image identification processor is configured for identifying a second image from the georeferenced images database that correlates to the first image. The system includes a communicative coupling to a geographic location information system. The reference feature determiner is configured for determining a reference feature common to both the second image and the first image. The feature locator is configured for accessing the geographic information system to identify and obtain geographic location information related to the common reference feature.

    • An electronic distance meter comprises an integrated circuit from a GPS navigation receiver having a local pseudo-random number code generator for code demodulation that is connected to modulate either a polychromatic or a monochromatic light source. An optical system focuses the light on a distant target with an unknown range. Reflections from the distant target are focused on a light detector that produces a phase-delayed copy of the original pseudo-random number code. The time-of-flight to and back from the distant target is a function of the distance. The GPS receiver integrated circuit computes the range based on the code-phase delay to a precision better than one centimeter. The position of a remote target can be triangulated from several electronic distance meters each having known positions, e.g., determined by included GPS navigation receivers. Conversely, the position of a single electronic distance meter can be determined by triangulation by ranging to several remote targets each having known positions.
    • 电子距离计包括来自GPS导航接收机的集成电路,该导航接收机具有连接到调制多色或单色光源的用于码解调的局部伪随机数码发生器。 光学系统将光聚焦在远距离的目标上,范围是未知的。 来自遥远目标的反射集中于产生原始伪随机数码的相位延迟拷贝的光检测器。 距离遥远目标的飞行时间是距离的函数。 GPS接收机集成电路将码相延迟的范围计算为精度高于一厘米。 远程目标的位置可以从具有已知位置的几个电子距离测距仪进行三角测量,例如由所包含的GPS导航接收机确定。 相反,单个电子距离计的位置可以通过测距到几个具有已知位置的远程目标的三角测量来确定。
