<div dir="ltr">Hello Danuvius,<br><br>I believe you could use qgis (<a href="http://www.qgis.org">www.qgis.org</a>) to save the open file as a screenshot.<br>quantum GIS would actually be a good start for you, that GADM shapefile is a vector file.<br>
<br>Now speaking of getting the whole lot into a PNG raster file, be careful, a vector of 600Mb would translate in a raster of a couple of Gbs at that original resolution.<br><br>Basically what you are looking for is a vector to raster converter. V2R<br>
<br>I would like to direct you to Quantum GIS as a start. GRASS is a Quantum GIS plugin, you will get what you need there. GRASS plugin has a straight forward Vector to Raster converter. <br><br>Unfortunately, I have not experienced using such a large vector file before, so I cannot guarantee it works, but you have a start here.<br>
I will send you separately my Quantum GIS introduction manuals, if any other person is interested, i'll send to them separately (big pdfs, step by step screenshots, easy).<br><br>Cheers and good luck,<br>Yann <br><br>

<div dir="ltr">Hi, Yann!<br><br>This is absolutely amazing. It is quite what I was fantasizing about, but never expected to be freely available.<br><br>I am however finding myself to be an unexpected dummy with GIS software. I am a pretty apt dabbler in all sorts of things hardware and software related, but GIS is really making me feel like an idiot. Is it genuinely so complex, or does it just employ a lot of jargon?<br>
<br>Long story short: Can you point me toward some specific way I could create a PNG (at however high resolution I choose) or an SVG out of the shape file (or better yet the ESRI geodatabase file, which I am yet to even be able to open)? All I've managed thus far is to save images of parts of the shape file currently displayed on the screen.<br>

<br>
have you tried GADM dataset? It has very high spatial resolution<br>
(originally 30m landsat pixels i believe)<br>
shapefile is here (careful it is huge!)<br>
<a href="http://biogeo.berkeley.edu/gadm/data/gadm_v0dot9_shp.zip" target="_blank">http://biogeo.berkeley.edu/gadm/data/gadm_v0dot9_shp.zip</a><br>
main website is here: <a href="http://biogeo.berkeley.edu/gadm/" target="_blank">http://biogeo.berkeley.edu/gadm/</a><br>
Any GIS software can do a buffer of 10 Km on a vector of following<br>
coastlines, choose your tool, then export to PNG for Marble to have<br>
it.<br>
<br>
good luck,<br>
Yann<br>
