I'm having real problems with Batchgeo at the moment, specifically the 'calculate straight line distance' feature. I'm trying to work out the distance from an initial post code (UK) to all subsequent post codes in my dataset. I'm setting the parameters correctly. I run the same dataset through twice and each time around 15% of the results are different, and different by quite a noticeable margin. I don't understand why the same set of post codes is yielding such different results and it's making me question the reliability of the distance calculation function. Has anyone had the same problem and how did you solve it?
Please send me your data set at firstname.lastname@example.org so we can test. When you send your data, send a couple of examples of where the data was different. Thank you for your information.
