2. CM93 "per cell" offset dialog.
Each cm93 cell contains one or more MCOVR objects, describing the datum and possible offsets which apply to objects within the boundaries of that MCOVR region. What is new here is that we have implemented programmable "user offsets" for each MCOVR object as well, so that individual coverage regions may be fine tuned by users so that they may better align with observed georgraphy or other (presumably more accurate) charts. User offsets will apply only to the MCOVR region(s) selected, and not to the entire folio of cm93 charts as is done in Version 2.3.1.
Here is how to use this feature.
1. Go to single
chart (i.e. non-quilted) mode, with cm93 charts displayed.
2. Zoom/Pan to the region of interest.
3. Right click, activate "CM93 Offset Dialog"
4. In the list of cells/MCOVR IDs, selected the one MCOVR of interest. The coverage area for this MCOVR object will be outlined
with a heavy yellow border.
5. Use the spin controls on the right side of the dialog to adjust the desired user offsets.
6. The offsets are automatically saved in the binary MCOVR cache files found in the program data directory as CM93/...
In order to use this feature effectively, one needs a geographically known reference point. As an example, say there is a NAVAID present on the chart cell with known wgs84 lat/lon, as from a light list. In this case, one can drop a waypoint on the chart, edit the waypoint properties to the known lat/lon, and then use the CM93 Offset Dialog to slew the cell/MCOVR so that the dropped waypoint coincides with the NAVAID feature on the cm93 cell (chart).
You may also use a geographical feature such as a cape or point whose location is absolutely known, as by reference to observation, or by rendering on another, more accurate chart such as a trusted scanned raster chart or georeferenced photo
3. TMerc charts are quilted with other TMerc charts. This should work well in areas (e.g. Sweden) where there are multiple overlapping
North-up TMerc charts. It will not work in South Pacific
, where there seem to be isolated (NZ?) TMerc charts.
4. By request, we allow more charts on the viewport to be added to the quilt. We add charts of an appropriate scale range to the quilt, even if they do not overlap with the center of the screen
. Of course, this will cause some performance issues for some locations and some systems. So, it is configurable in Toolbox.
14. PlugIn API Version 104: This will be transparent, but will enable the BSB4 and other PlugIns coming soon.
Good Luck testing, and keep those Flyspray tasks coming.
Don't forget to update "your" Flyspray tasks with with test results. That way we can close the tasks as appropriate.
Sorry about the temporary un-availability of the Windows installer. Should be uploaded soon.
