<div>Dear Ruth,</div>
<div> </div>
<div>thanks for your brief description.</div>
<div>My fault was to load the raster to be georeferenced into the view as usual. Thus having the cadastral vector as well as the raster image in the view the georeferencing module did not work properly (I guess).</div>
<div>So I was wrong at step number 1 already. </div>
<div>Oh well, now it works perfectly.</div>
<div>Many thanks!</div>
<div> </div>
<div>Best,</div>
<div> </div>

<div text="#000000" bgcolor="#ffffff">Dear Johannes, <br><br>here is a small description of the way I do georeferencing with gvSIG 1.9 USB.<br>Maybe there´s some helpful hint between the lines?<br><br>1) First load the reference layer (cadastral map) to gvSIG view.<br>
2) Start the georeferencing tool, choose "with reference cartography" and select as "georeferencing file" the raster image (aerial photograph).<br>(georeferencing algorithms (afin, polinominal transformation, pixel size, etc.) can also be defined later)<br>
3) After accepting the window for settings the two data sources will be displayed as the following: <br><br>- on the left side: reference layer (e.g. your cadastral map)<br>- on the right side: georeferencing file (e.g. aerial photograph)<br>
<br>Try to work with the navigation tools (especially pan and zoom in) on the right side of each window, to get the two extents of the data sources displayed correctly side by side. Maybe your cadastral map is already displayed in the left window, but yet too small to recognize?<br>
<br>4) The control points can be set very similar to gvSIG 1.1.2, by selecting the tool "New" at the GCP panel and placing them (first the pixel point, second the real coordinate) into the georeferencing windows or the small zoom windows on the right and left bottom of the screen. <br>
<br>5) RMS will be displayed with 3 GCP<br><br>6) It is possible to test the georeferencing first (green tool in GCP panel) <br><br>Good luck and best regards!<br>Ruth<br><br><br>Am 26.04.2010 15:08, schrieb Johannes Valenta:

<div>Hi list,</div>
<div> </div>
<div>trying to georeference a raster image (aerial photograph) I get stuck with the georeferencing module.</div>
<div>
<div>I'd like to use a cadastral map (shapefile) as referencing source but compared to gvSIG 1.1.2 I cannot set points on both layers (image and shp) within gvSIG 1.9.</div>
<div>By starting the georeferencing module two windows are displayed with one showing the image whilst the second (where I was expecting to be able to zoom to the cadastral map) stays empty.</div>
<div>What am I missing?</div>
<div> </div>
<div>Hints/ideas are appreciated.</div>
