How to save a raster and vector into a single PNG file in GRASS?

Question

I am trying to save a raster and vector into a PNG file. The vector is overlayed on top of the raster map. I was only able to save the raster file into a png using r.out.png but without the vector.

Answer 1

Compose your map and export using d.out.file http://grass.osgeo.org/gdp/html_grass64/d.out.file.html

Answer 2

Try this:

d.mon start=png
d.rast RASTER
d.vect VECTOR
d.mon stop=png

This will basically render VECTOR layer on top RASTER layer to a file called map.png.

Other things you could do with d.mon start=png - d.mon stop=png:

• Type d.erase to wipe the slate clean before committing with d.mon stop=png

• Include the legend with d.rast.leg:

  d.mon start=png
  d.rast.leg RASTER
  d.vect VECTOR
  d.mon stop=png
  

• Put the legend to a separate image with d.legend:

  d.mon start=png
  d.legend RASTER
  d.mon stop=png

I think this is going to depend on what software you're using.

Also, I think that in saving them as a .png, you're going to be losing any distinction between the two, as far as being able to use them separately.

Anyways, in the case that you're using Arcgis, you should be able to go:

File --> Export Map, where you can save your current view as a .png.

Maybe use ps.map1 to export vectors and the raster to a *.ps. Then just convert the *.ps into *.png (convert out.ps out.png)

Answer 5

The simplest way, I guess. Display the desired layers to elaborate your map and simply make a screenshot. Then, save as png.
