Hi

I'm trying to import in google earth pro, more than 5000 line segments compose from (X, Y) lon/lat coordinates. So for each line segment I am having 2 lon/lat coordinate.

I want those line segments be represented a straight line in Google Earth Pro. So I probably need to convert them into vector ??? Correct me if i'm wrong?

Any one has a idea how to process andhow to cenvert multiple records in once?

Here's an example of my data

Line_Segment_Name From_Lon From_Lat To_Lon To_Lat
Line Segment A -66.9397 47.9746 -66.7737 47.9848
Line Segment B -66.9397 47.9746 -66.7027 48.0352
Line Segment C -66.9397 47.9746 -67.0392 48.028

Thanks

How do you have the data - is it in a text file or database? I find the easiest is to create the KML file from scratch (using something like python). That would give you most control over the output.

To get a template for what you want - create a dummy file in GE and export it as KML, then modify it and use it as a template.

My data is stored in an Access database, but I can easily move it to Excel spreadsheet or a text file without a problem, but I wasn't able able to find on the net any formula that will convert multiple from / to coordinates (lon/lat) into straight line.

Better to plot the xy data as line work, i have done that this earlier for routing assignment using autocad, its works well..try.

Thanks and Regards

If you have access to ArcGIS, you can use their Points to Line tool (link for add-on script, though I think it's standard in the latest version 10.1). Just see that each vector has a unique identifier (maybe your Line_Segment_Name already does that?), and the tool can construct a unique line for each unique identifier, using the vertices that belong to that identifier.
