Last week I was sent a Shape File which defined the outline of a block.

I was asked if I could provide the coordinates of the corner points.

Whilst there are some obscure ways to do this, it is difficult without a full blown GIS application.

As the question seems to be a fairly common one, I wrote ShapeReader to extract coordinates and various other information from Shape Files.

More VAPSDB3 Updates

Saturday, April 21st, 2018

A bunch of updates to VAPSDB3.
The biggest being the addition of an Export facility, where you can select desired attributes based on various criteria.

The other big change is the ability to output Shape Files.
This is especially useful for anyone using GIS packages for further displays.
