comment Data types for storing lng/lat in MySQL
Thanks for the answer - I've read through the MySQL Spatial Extensions documentation, but how do you start to use them? I just have a default MySQL DB on GoDaddy; I don't know where I should start.

comment Using multivalue output parameter with ArcPy?
There is a question on esri forums forums.arcgis.com/threads/… (with no answer). Could you add some code to make it a little clearer? I'm not sure I understand the question still (having read this one, and the esri forum one)

comment Finding nearest raster cell value based on vector point?
@Seen you can clip a raster to a polygon. I'm not sure if you can reduce the raster area that you need to convert, before converting it to points.
