[. . . ] For example, the corrected version of Tutdata1. ssf will be called Tutdata1. cor. In the Processing group, make sure the Smart Code and Carrier Phase Processing option is selected. This is the default setting and it is the most thorough type of processing. 72 GPS Pathfinder Office Getting Started Guide Tutorial 4 10. A series of progress bars indicates the status of the operation. GPS Pathfinder Office Getting Started Guide 73 4 Tutorial When the process is complete, the following message appears: 13. Click Close to remove the message without displaying the correction log. In real use, if not all of the positions were corrected, you can click More Details to display a log file to help you track down the source of the error. 74 GPS Pathfinder Office Getting Started Guide Tutorial 4 4. 1 Lesson 4: Viewing and Editing the Data You now need to visually check the data before you export it to a GIS or spatial database. This is to confirm that all the expected data is there, and to look for any unwanted positions. This lesson shows you how to: · · · · · · · · open the data files select a coordinate system display the Map window display the Time Line window load the background files configure the Map window view the attributes of a feature view the offset of a feature It takes approximately fifteen minutes to complete. GPS Pathfinder Office Getting Started Guide 75 4 41. 1 Tutorial Opening the data files You must open the data files in the GPS Pathfinder Office software to view them. You can open as many files as you like together, but you can only edit files if they are opened individually. The following dialog appears: The three files that were just created by the Differential Correction utility are selected by default. Click Open to confirm the selection. 76 GPS Pathfinder Office Getting Started Guide Tutorial 40. 1 4 Displaying the Map and Time Line windows There are two methods available to display the data. The first is the Map window, where the file appears along with any background files. The second is the Time Line window, which presents a visual display of when the data was collected along a linear time axis. The Time Line window appears: B Tip ­ If the Map window is not open and no files are loaded, select View / Map to automatically open the Open Data Files dialog. The same rule applies for the Time Line window. GPS Pathfinder Office Getting Started Guide 77 4 40. 1 Tutorial Loading the background files You can specify one or more background files, such as street maps and aerial photographs, for display in the Map window. There are two types of background files: · · Vector files (or drawings) Raster files (or images) Vector files A vector file loads and transforms into any coordinate system The vector file Streets. dxf has its coordinates stored as Latitude/Longitude (WGS-84), but the coordinate system for the project is currently set to UTM. We will need to specify that this file is set to the Latitude/Longitude coordinate system so that the GPS Pathfinder Office software can automatically transform the file from that coordinate system into UTM. Raster files Raster files must be displayed in the coordinate system to which they are `geo-referenced'. Geo-referencing involves matching the pixels in a raster file to real-world coordinates. All raster files must be geo-referenced before they can be loaded into the GPS Pathfinder Office software. The raster file Aerial. bmp is geo-referenced in the UTM coordinate system, and UTM is the coordinate system for the project. You will load the two background files one at a time so that you can see what each background file looks like individually. 78 GPS Pathfinder Office Getting Started Guide Tutorial 4 To load the background file Streets. dxf: 1. [. . . ] For OpenGIS, the Web Map Server coordinate system is described using the European Petroleum Survey Group (EPSG) standard EPSG codes. The most commonly used code is EPSG: 4326, which corresponds to WGS-84 (Lat/Long). The EPSG website (www. epsg. org) has a link to a Microsoft Access (. mdb) database that lists all the EPSG codes and a description of the corresponding coordinate system. Note ­ If you have problems opening the . mdb file provided, try importing the tables contained within the database into an empty . mdb database. Table A. 6 Symptom Web Map Server layers do not appear in the GPS Pathfinder Office software. Before you contact Trimble Support with any Web Map Server queries, work through the solutions described in this troubleshooting section. [. . . ]
