I'm working on the Atlantic ocean for my research and I need to create an animation of movement of few islands in the Atlantic from their past locations to their present locations that moved due to plate tectonics. Input will be a postscript file of that region.

enter image description here

Are there any tools which can do this task?

  • There are many GIS programs that can create animations based on a Time attribute or multiple attributes. Postscript files are not typically associated with GIS. Can you tell us more about the postscript file? How was it created? With what software? – Fezter Mar 12 '15 at 5:47
  • The file was created from satellite altimeter data using Generic Mapping Tools(GMT). I can give jpeg file as output(if that helps) – Thoram Mar 12 '15 at 6:06
  • Can you post an image of one of your outputs? I'm thinking you could use the open source GIMP program to produce animations of your images. – Fezter Mar 12 '15 at 6:59

My usual method is to use the convert utility from either ImageMagick or GraphicsMagick to convert a sequence of still images from a variety of formats, including PostScript, and output a variety of other formats, such as an animated GIF or MNG.

For example, from a directory with several PostScript files, make an animated GIF with 0.2 seconds between each frame:

$ convert -delay 20 map*.ps map.gif

ImageMagick's version has many more options, such as -layers method, which can be used to control how a GIF animation is constructed. There are also plenty of options to control how the PostScript files are converted too. You may want to pre-process each PostScript still files into individual .png frames if this step is complicated.

Also, make sure your file names are sequenced correctly, like map0001.ps, map0002.ps, ..., map0365.ps, otherwise you might have odd jumps of frames.
