I am part of application development team. We are writing an application which takes several geographic files (shape files) and finds where a coordinate intersects with each of the files
I would like to allow the user to enter an arbitrary amount of geographics files. e.g. he could find the intersection with 1 to 10 shape files.
I wanna know what is the best practice of choosing several files. Currently I give the user to choose a directory where all the shape files are located however it doesnt feel right.
