Layer:export

[pedro-andrade-inpe]

Allow exporting a Layer into a different format. Think about the required parameters for this function.

[pedro-andrade-inpe]

For example, one could export a tiff Layer into a NetCDF file.

For now, it will only be necessary to implement the following usage:

layer:export{file = "myfile.shp"}
layer:export{file = "myfile.geojson"}

The arguments need to be named because in the future we can add more parameters.

@hguerra, is it ok for you?

[hguerra]

it may be interesting can re-project CRS like GDAL does:

GDAL code:

ogr2ogr output.shp -t_srs "EPSG:4326" input.shp

layer:export{file = "myfile.shp"}
layer:export{file = "myfile.geojson"}
layer:export{file = "myfile.geojson", crs = "EPSG:4326"}

Once that many frameworks define a specific CRS to use, mostly WGS84 lat/lon.

@hguerra, in fact this is another requirement. We have not worked with projections yet. I will add another issue for this.

@pedro-andrade-inpe, is the exported layer must go to "project.tview" (to be a layer)?
