I'm trying to build a simulator which needs to know what the terrain looks like in front of a given location.
I know that we can get elevation data from the National Elevation Dataset, but once I have it.. I'm pretty lost.
I was reading through the comments on this question, and the answers make sense, but I can't run a Postgres server for the data on Android like they can for a website that needs the same information.
I need to be able to load the elevations for points a given distance in front of my current GPS lat/long, so I need to be able to search the dataset.
Additionally, I need this to work without a data connection, so it has to all be on the phone with no network needed other than a GPS connection.
Where should I start? I'm pretty much lost =\
I guess, what I need is.... I have the elevation data in ArcGRID or GRIDFLOAT format from the USGS. Now what? I can't find good examples of working with the data.
