I am new to GIS and developing an application that generates a 3D grid with (latitude, longitude, elevation) or (x, y, z) metric triplets, and I would like to add an exporting feature that ensures compatibility with the most GIS software.
In case of several possibilities, I'd love to understand the pros and cons considering the current industry standards and also the "efficiency" of the format, as I'd like to reach the largest number of users.
UPDATE: I did a bit of homework but I am still a bit lost with the variety of formats. What I have come accross which seem interesting: GRD (Surfer), KML (Google), DXF (AutoCad), WRL (seems cool but not used anymore), SHP (ArcView - closed format?)
Anyone could help me choose?
