#142: WinGRASS Native: Ground Control Points Usability
-----------------------------------------------------+----------------------
Reporter: RRosario | Owner: grass-dev@lists.osgeo.org
Type: enhancement | Status: new
Priority: major | Milestone: 6.4.0
Component: Tcl | Version: 6.3.0 RCs
Keywords: wingrass ground control point usability |
-----------------------------------------------------+----------------------
There are several usability issues with the current ground control points
dialog on WinGRASS:
1. When a point is selected in the map display, the cursor in the GCP
dialog does advance to a new field to record the next point clicked. The
user must manually click on a new field to select a new point, otherwise,
the same point coordinates are overwritten and there will be more points
selected than there are recorded GCPs entered.
2. There should be a visual divider that separates each entry column:
Coordinates, Geographic Coordinates etc. Currently, some users experience
errors because they attempt to use the spacebar to move to the next field.
3. When the user clicks on a point in the map display, the decimal
precision of the clicked point can fill in the entire field up to the next
column, confusing the user into thinking that there is no way to advance
to the next field (geographic coordinates). This is resolved by simply
clicking in the second column, but the cursor appears in the same
location. This could also be resolved by resolving #2 above.

Comment (by mlennert):
1. is not limited to WinGRASS, but 2+3 are (although the limit between the
fields is not very easily visible either, depending on the screen, but it
is not nearly as bad as in winGRASS).

Comment:
1. In the new GCP Manager, there are several ways to navigate through
points: "Go to GCP No." in the statusbar, clicking on a row in the list,
or using up/down arrow keys when a row is selected/active. Helps?
2. Probably no longer applies because there is an extra dialog for
manually editing coordinates. If a point in the list is selected and the
spacebar is pressed, this dialog appears (both Georectifier and GCP
Manager).
3. Does this refer to a different layout? The ticket is 2 years old, maybe
something changed. Advancing to the next field (column) is not (no
longer?) possible in the list, a particular entry is edited with the
editing dialog or by clicking in the maps.
