So you will want to choose a coordinate system that matches the goals of your project.įor example, if the goal is to have polygons with the correct area but are not so worried about their shape getting distorted somewhat, an Equal-Area coordinate system would be a good choice. There is no coordinate system that preserves all 4 instead, each coordinate system is set up to preserve some of the factors at the expense of others. Essentially all coordinate systems are a trade off between 4 factors: shape, area, distance, and direction. That said, there are likely several available and it will not be obvious at first which one to choose. Instead, you want a projected coordinate system that covers the whole state. To build on what Micah Babinski stated, since Texas has multiple UTM zones, picking one UTM standard zone to try to use for the whole state won't work that well.
