In the resulting "Combine Data Files" window, press "Browse" to bring up a list of files in the folder. Note that as you highlight a file name by […] Examining GPS Data (GPS and GIS) Part 4 An Aerial Photo That Can Be Used as a Map:The Digital Orthophoto A digital orthophoto image is an aerial photograph, in digital form, with a very useful special property: It has been calibrated so that it may be used as a map; the coordinates of the map are precisely specified. As you may know, most […] Differential Correction (GPS and GIS) Part 1 IN WHICH we take a closer look at the subject of GPS accuracy and explore techniques that reduce errors. OVERVIEW GPS Accuracy in General When you record a single position with a good GPS receiver, the position recorded will probably be within 5 to 15 meters horizontally of the true location of the antenna. When […] Differential Correction (GPS and GIS) Part 2 Making Differential Correction Work From a practical point of view, a number of conditions have to be satisfied for the process to work. The base and rover have to be taking data at the same time, and the base has to be taking data frequently. If the base station is to serve the rover, wherever […] Differential Correction (GPS and GIS) Part 3 PROJECT 4C—McVey Waypoint Waypoints—Using One to Check Your Work {_} The McVey monument is a good candidate for a waypoint since it is a known reference point. We will do this in order to see another way of calculating the distance from a corrected average point to a known point. Still in the __:\GPS2GIS\McVey_NGS directory […] Differential Correction (GPS and GIS) Part 4 PROJECT 4F—The OK Campus More GPS Files and DOQs In this Project we verify again that
