Free GIS Book - Mapping Math Chapter Update

I missed my last two Free GIS Book writing sessions on Sunday morning. But I took some time out on my lunch break today to catch up. I’ve added a little more content to my Mapping Math Chapter of the Free GIS Book. You can find the new content here:

The new content on this page includes a definition of a point, and finally a definition of a distance. In the next section I hope to talk about some techniques commonly used to measure the distance of straight line segments, and then I’ll talk about how you can calculate or indirectly measure the distance of curved line segments.

My progress is slow, only about 5 or 6 paragraphs a week, but it is steady. I will try to be patient and persistent in my efforts. Hopefully, after several months, I’ll have something worth reading!

As always, I welcome comments and suggestions on the content, style, and format of the material in this chapter.
