"google map maker" like. need a good flash, or flex (better maybe) developer, to create a webapplication, like google map maker, one requirement, not use of any API like google map or yahoo or whatever, cause : the application will be use on a area not covert by google map or any of open source map engine. The application is tobe build from nearly scratch, but client will help provide digital maps and coordinate. the application will then enable user to enter data just like google map maker, such as street, monument, buildings ..... Application will be base on GIS technology ( multiple layer ).
