Data acquisition from text file

[JulianHeinz]

Hi!

I have the following problem to solve and would like to know if Measurement Studio for VC++ can help:

I would like to read data from a text file with NMEA strings (see example below) and plot them. For instance, the text file contains latitude and longitude values form a GPS which I would like to visualize. Thus, does MS offer an method to read values from a text file, store and plot them?

Here is the example data:

Hi Julian,

of course it is possible to use Measurment Studio for this application. I did not found any example which solves your task. Did you already start programming? A XY graph is available. The NMEA strings are officially documented. You have to do some parsing work on your own.

In general your question is a Visual C++ topic and not Measurement Studio specific. Perhaps somebody else published the solution on the web. Did you do some research?

Kind Regards,

VanS

Hi Julian,

i am also working on NMEA data and facing the same problem. I have used Marine-api and using netbeansIDE for Testing my java code.  i have extracted the required TalkerIDs and SentenceIDs for obtaining the Position parameters from the received GPS data. Now i want to plot a grid view and show the latitude and longitude point on that Grid. 

can you help me regarding this problem. 

thank you in advance.

regards,
