node-wmtiff's Issues

Segfault with unknown SRS

When running wmtiff with a tiff that has an unknown srs, we get a segmentation fault in gdal.suggestedWarpOutput, which isn't caught and leads to some nasty things upstream. I think it would be good to wrap the reprojection process here within a try/catch, which is pretty standard for node-gdal.

Uncaught error:

Hit an uncaught error with the gdal.open() method earlier today:

/Users/mapsam/mapbox/node-wmtiff/node_modules/gdal/lib/gdal.js:546
			return driver.create.apply(driver, args);
			                     ^

Let's add a try/catch around this so we can return something more useful.

Reproject function should not accept a callback function

The reproject function is not asynchronous, and hence it should not accept a callback function.

If it does, it would be anticipation of asynchronous support in node-gdal, and in that case it needs to try/catch errors that could arise from node-gdal calls and provide those to the callback.

Vague [Error] during from gdal.reprojectImage()

When running gdal.reprojectImage() with a particular file, the error returned is simple [Error] and is missing a message. Perhaps these GDAL operations aren't producing errors as expected?

Here's the gdalinfo from the file:

I'll work on creating a test fixture
