I am a conservation biologist (with 15 years international experience) who is now working in the Spatial industry. One of my projects was awarded the GITA Australia and New Zealand Spatial Excellence award for 2013 and Highly Commended at QSEA. I have presented at several GIS and Disaster Management conferences in Australia since I moved in 2010.

I am focused on automating large processes using python along with ESRI/Mapinfo and open source GIS tools that complement the strengths of each other. I also work in Disaster Management and risk mitigation.

comment Calculate length of line across zones with at least m accuracy
I created the points using GDA94 and not MGA. It is for pigeon racing from start point to the loft. We were just concerned by the different distances but if we use one method then the relative distances will be the same.

Google Earth gives 467.28 which is closest to the GDA94, Shape.length value.

comment Calculate length of line across zones with at least m accuracy
Thanks. I am now getting 465.360 which is much lower than the values in GDA94. It is a methodology and projection based issue - I want to figure out what the best system to use is.

Thanks @PolyGeo -when the dataset is converted to 3577 (Australian Albers) and I now get 468.467, that's now a 2km difference between the GDA94 based calculations

comment Draw line between points from multiple datasets
We don't have business analyst. One issue is that the points are across the 54S and 55S boundary and I am using GDA94 but then arcgis won't Calculate Geometry of the line as it's Geographic. I looked at ET Geowizards but can't find an appropriate tool. The Mapinfo distance tool suggested does the same as the point distance tool.

thanks but the 2 tools are giving errors. See updated q. Do you know what I should do to fix this?

Mapinfo would be fine as well...
