<div dir="ltr">Mike,<br>Here is a good tutorial overview of the georeferencing tool in QGIS:<br><a href="http://qgis.spatialthoughts.com/2012/02/tutorial-georeferencing-topo-sheets.html" target="_blank">http://qgis.spatialthoughts.com/2012/02/tutorial-georeferencing-topo-sheets.html</a><br> <br>If the image is not in coordinate space, it will not line up with your other data. so this operation will be necessary.<br> <br>Also, just as a side, I would think that an export from Powerpoint would degrade image quality (depending on the original). I would look at and maybe try for future use The Gimp (which is an open source, free Photoshop-type application). It will give you more control on export of not only various output formats but also pixel and color depth, and the like. The official site is <a href="http://www.gimp.org/" target="_blank">http://www.gimp.org/</a>.<br> <br>Best Regards,<br>James<br> <br><br><div><hr id="ecxstopSpelling">Date: Mon, 3 Feb 2014 19:59:14 -0500<br>From: tmike.elhoa@comcast.net<br>To: tech@wildintellect.com; etourigny.dev@gmail.com<br>CC: qgis-user@lists.osgeo.org<br>Subject: Re: [Qgis-user] How do I register a Google Map?<br><br>
<div class="ecxmoz-cite-prefix">OK, I installed the Open Layers plugin
and it works very nice but it won't do what I need, so let me be
more specific and see if there might be a remedy. <br>
<br>
The contour lines that I want were actually obtained using a hand
held Garman GPS. The Garman data was overlaid on the Google map,
(with water depths), special integration, then that map was
exported as a Jpeg, then imported to PowerPoint where a visual
interpolation was done to make the final set of contour lines for
the various lake water depths.<br>
<br>
My desire is the <u>digitize</u> these contour lines as a set of
separate layers. ie 5' deep, 10' deep, etc. There are many good
uses for these layers, but they must be accurate as to location
and size. I don't think I necessarily need spacial info on the
"map"/Jpeg if I can get the whole map in the right position, and
size, so I can do the digitizing (which would then have the
spacial info). Then I can discard the Jpeg.<br>
<br>
Is it hopeless?<br>
