SnakeGrid PointWise is the basic tool for converting coordinate sets between ellipsoidal (latitude and longitude) systems and SnakeGrid Eastings and Northings. Input/Output is in a variety of pre-set formats and the required SnakeGrid parameter file is loaded up by the user.
The formats supported include different variations on decimal or degrees/minutes/seconds, and versions with or without ID strings, or accompanying height values (output without transformation), and with optional text strings. However, it is emphasised that this tool is for simple coordinate lists (or single point manual entry) and not for structured data.
For many users, the latitude/longitude coordinates will not necessarily be of interest in themselves, but these can then be transformed into another coordinate system – for example a different SnakeGrid where one project meets another, or a national coordinate system such as Ordnance Survey National Grid.
The current version of SnakeGrid PointWise is v4.1.1.
The previous version of the software was 4.0.1, but was just branded SnakeGrid. The main change was the ability to accept ASA parameter files as well as standard v4 files.
There are no licence fees associated with this software, and we are happy for clients to share copies or to pass on to sub-contractors and other associates. There is a simple licence acceptance screen on start-up. Copies of SnakeGrid PointWise can be downloaded from here.
