| There is no way to create 100% accurate terrain for a great number of reasons. So striving to do the "best possible" based on accurate data is a worthy goal. Getting the general layout and "look and feel" will be more than enough! | There is no way to create 100% accurate terrain for a great number of reasons.

| + | ====== DEM Data ====== | ||
| + | |||
| + | Usually if no data can be obtained after querying Google a couple of times, chances are you're not going to strike gold. US NED data is available for free in: | ||
| + | |||
| + | 1 arc second (~30m) | ||
| + | |||
| + | 1/3 arc second (~10m) | ||
| + | |||
| + | 1/9 arc second (~3m) | ||
| + | |||
| + | The few rare instances where DEM data higher than 3 Arc Second (~90 meter) res is available is usually provided by the government of the specific country. | ||
| + | |||
| + | Q: //If not, can you use 90m DEM or is it just too low resolution?// | ||
| + | |||
| + | A: I guess that would be subjective, personally I would aim to use the 90m data as a template and add in finer details utilizing 'artistic freedom (like Avgani for example). | ||
