Generic (User Defined) Raw Data

Generic Raw data files are text files that contain field data like point labels, angles and distances. They are similar to ASCII coordinate files which contain coordinates only.

Rules for Generic Raw Data Files

The files can have any combination of point number (alpha or numeric), northing, easting, elevation and description. The following rules apply to all files imported by TPC:

Default CSV Settings

By default, TPC uses comma delimiters and the CSV file extension for the Generic Raw Data files in order to match the CSV files used by Microsoft Excel. You can write a Generic Raw Data file using the default settings and open it directly with Microsoft Excel.

Importing a Generic Raw Data File

TPC will import the file and put all the imported points into a traverse.

Determining the Format of an Import File

Before importing a file, it is important to determine the file's format.

If you do not know the file format, Choose Preview File. Examine the file format, looking for the pattern or format of the data.

Telling TPC which format to use

The backslash ( \ ) at the end of the data line is for a “line break.” You must enter the correct delimiters (commas, spaces, +, -, or quotation marks).

What if you specify the wrong format?

If you specify a format that doesn't match the format of the imported Generic Raw Data file, TPC will still try to read the file. It will do the best job it can with the format you tell it to use. The file will come in with errors though, such as zeroes for coordinates and almost anything for field notes. If the imported data is wrong or unusable, you can specify the correct format, and go through the above steps again.

Importing Geodetic vs Coordinate Positions

If an imported point includes just the geodetic position, TCP will give the resulting survey point geodetic preference. Now you can modify the survey's CRS and recompute coordinates for the point based on it's preferred Latitude and Longitude.

If an imported point includes just coordinates, TPC will hold the coordinates of the resulting survey point and generate the corresponding latitude and longitude based on the survey's CRS.

If you import both coordinates and latitude/longitude for the same point, the latitude/longitude will take preference over the coordinates for that point. If however, you are overwriting existing survey points, the geodetic preference of the existing surveys points will be retained.

Using the imported data

Once the data is in TPC, you can reconstruct a survey, print the field data, balance coordinates, plot the traverses, inverse points, or whatever else you want to do. When you are finished, you can export the same points to any other generic file format, or save all your work as a TPC file.

Exporting Generic Raw Data Files

TPC can export generic data files for use with other computer programs. The steps for exporting a file are similar to the steps for importing a file, with the exception that you may need to include file delimiters and quotation marks when you specify the format of the export file. The following rules apply to all files exported by TPC:

Exporting the entire survey

Exporting selected traverses or points
