[Gvsig_english] View Frame Properties of Map Buggy

Wed Jan 6 02:28:03 CET 2010

Hi Enrique Lorenzo,

Thank you very much for the feedback. Your workaround was successful in 
avoiding the problems previously encountered.

A couple of points though...

1. I found that I could open already prepared MAPS and just change the 
settings in the way outlined below to get the program to work properly 
(that is I did not have to start afresh).
2. I found it was not necessary to uncheck the LIVE LINK. This is 
desirable as I wanted changes to the reference VIEW to reflect in the 
various MAPS.
3. All I needed to do to get the VIEW FRAME to behave in the MAP was to
      (a) select the VIEW,
      (b) select "keep constant" in the scale drop down list,
      (c) leave the edit box requesting the scale value as is or specify 
a scale,
      (d) select "maintain view scale" in the scale drop down box, and then
      (e) select accept.
Once this was done I was able to pan, zoom in and zoom out. I also tried 
to separate the grid from the view by zooming in and was unable. In all 
I adjusted my 13 maps in about 1 hour. Not bad.

SO ALL THE LATEST ISSUES RELATED TO MAP PRODUCTION HAVE DISAPPEARED** -- 
Enrique Lorenzo you are genius, how in the world did you discover this 
quirk?

[** inserting an image on a map still triggers an error as described in 
previous posts]

So the upshot is...
1. I have one reference VIEW, which I can change the legend values to 
generate site maps, historic vegetation maps and current vegetation 
maps. The effects are reflected in the appropriate maps.
2. In the absence of having a way to consistently zoom to the same spot 
(e.g. with regions of interest or spatial bookmarks as recommended by 
Jorge Gasper) I have created a MAP for each reserve or section of 
reserve. All MAPS point to the same VIEW. The MAPS retain the same 
extent as setup using the pan/zoom tools irregardless of what the extent 
of the reference VIEW is. This is expected behaviour.

FURTHER SUGGESTIONS FOR IMPROVED FUNCTIONALITY IN  MAP VIEW PROPERTIES 
DIALOG

1. LIVE LINK should be renamed to REFLECT CHANGES TO REFERENCE VIEW'S 
LEGEND; or alternatively...

2. It would be useful and clearer if a set of three controls were 
established. The reference view is the view that the map frame points to.

(a) REFLECT CHANGES TO REFERENCE VIEW'S EXTENT

checked = map's view frame moves with reference view. Move the reference 
view the map moves. Move the map the reference view moves. Both have the 
same extent (to void problems with different sized views and map frames; 
this would best be described as same scale and centre point).

unchecked = the extent of the map's view remains the same.

(b) REFLECT CHANGES TO REFERENCE VIEW'S LAYERS

checked = the layers shown in the map's view frame are the same as the 
view. Changes in what layers are visible in the view are reflected in 
the maps view frame.

unchecked = the layers visible in the maps frame are fixed (not changes 
to the layers symbology though; see 'c')

(c) REFLECT CHANGES TO LAYER'S LEGEND IN REFERENCE VIEW

checked = changes to a layer's symbology is reflected the the map (if 
'b' above is 'checked' or if 'b' above is 'unchecked' the layer was 
visible at the time the frame was fixed)

unchecked = all the legends of the layers visible in the map's view 
frame are fixed. This means that if the symbology in the reference view 
is changed for any particular layer it will not automatically be 
reflected in the maps.

If (a), (b) and (c) are unchecked then the map is a static once-off map 
that will never change.

(3) The property dialog for the map view frame should be fixed so that 
you can enter it and all the currently set options are apparent and they 
will only change if you make a change and press accept. As noted if you 
have more than one view in the project and you enter the properties 
dialog box, change the scale and don't remember to point to the actual 
view you want the map's view will change.

> You stated they using "maintain viewing scale" froze the map. The is the case if you can use the navigate tools to move the map to the right location. Using zoom in/out and pan does not work. On occasion I have fluked getting the map in the right  location you can freeze the zoom, but this only works when you only have one map for a view. Add another to the mix and gvSIG gets confused and the "freezing" is lost.
