Gee we encounter some unusual stuff on this list, such is the power and flexibility of CF. So here's something a little out of the ordinary that I hope someone may be able to provide some advice on. I'm putting together an app that allows entry of a grid reference (latitude and longitude) into a database that corresponds with the location of a given event. When someone clicks on the link I want it to interrogate the South Australian map server and produce a map. The problem is that the map server uses Lamberts Projection (which is based on meters from a given starting point, not degrees as lat and long is). It can be converted and there are formulae around but its a complex set of trigonometry and geometry. Has anyone had any experience with this type of maths in CF? Secondly, given the complexity of the maths, would I be better off doing the maths when an entry is created and storing it for retrieval, or doing the maths on the fly when the map is requested. From a single grid reference I have to create 4 "lambert" values that I can pass to the server so that it produces a given map of a given zoom. ******************************** Kevin Parker Service and Communication WorkCover Corporation [EMAIL PROTECTED] ph: +61 8 82332548 fax: +61 8 82332000 ******************************** **************************************************************************** This e-mail is intended for the use of the addressee only.
