  1. enable source map to be rotated

    enable the source map to be rotated (preferably in increments of say 10o) so that north is at the top.

  2. make it more obvious how to delete a control point, because I can't work it out

    Also, if a control point is heavily skewing the map (and is thus probably inaccurate) it should be pointed out to the user.

  3. Indicate maximum image size

    Message says source image is too big. File is .png format and does save, however, will not save as cropped.

  5. Allow multiple crop areas per source page

    Sometimes there are multiple maps on a source page. if you allowed multiple crop areas or had a way to flag that there is additional information that was not captured, that would help

  6. add functionality for dealing with alternative map projections

    I was working on georeferencing a map of the Arctic and surrounding regions done in an azimuthal projection, but attempting to fit it to the OSM/MapQuest cylindrical projection simply did not work out. Also, a means of adding notes about a map might be nice too as there was no way to flag or otherwise indicate a (currently) un-georeferenceable map.

  8. Compare two old maps next to / over each other without deformation

    We should add a mode to display two maps without deformation - either synchronized (when panning/zooming on one the other is displayed too) or overlayed...

  10. Detect automatically points which will form wrong georeference and warn users

    The Georeferencer should display a warning in case a user is trying to save georeference which is going to be for sure not accurate.

    Typical problems:


    • Less then minimal amount of control points (two/three/four points - to decide)

    • All points are in one line (affine transformation is not possible to calculate then).

    • All points are very close together - the points should be ideally spread around the whole map.

    • There are points with a very high calculated error

  11. Downloadable georeferenced maps

    For example, the Blais maps of Los Angeles are viewable in the Georeferencer which means the which means the info is there. So let us download a GeoTIFF or similar. Thanks for listening.

  12. synchronised zoom-in

    allow synchronised zoom-in across two maps when georeferencing based on points already georeferenced/saved. When one point is clicked, show approximate location of other in the other map.

  13. Integrate MapAnalystOnline directly into the georeferencing window

    It would be nice to see the results of one's work directly. When I saw that the MapAnalyst mesh does not cover the whole area of a map I felt obliged to add more points to the map :-)

    It would be nice if it was possible to just switch the mesh on ond off during the georeferencing process. Also, seeing the shift of some of the points might help spot incorrectly placed points.

  14. saving crop outline when no points present

    When the georeferencing starts with the creation of a crop outline it is impossible to save the outline - georeferencer wants at least 3 points first.

  15. Distortion live preview and initial placement, scale and rotation marker.

    A lot of reference points in maps without rigid or rotated CRS or of insurance map type only become easily apparent after transformation in map overlay. Would be great to have a live preview of the referenced map (preferably realized in 2D-Canvas) to continue referencing with the information already entered.

    There might also be a complex initial marker type with interactive handles for position scale and rotation to get started with maps of unknown or known non-north orientation.

    draggable handles would be O,N and Scale where O is the position(x,y), N the orientation, or rotational…

  16. add a button: Report Problem with Map

    I just tried to georeference and ended up with this map: http://britishlibrary.georeferencer.com/map/cUPNM96sjanZDMSmwY5oRu/201407062019-NNjMnZ/ which is a composition of two different maps in an image. I would like to have a button where I can report problems like these to a curator which will then take the appropriate steps (in this case split the image into two different maps, which can then be georeferenced). A button like this could prompt a form where the user can maybe enter the type of problem from a preselected list and add free text describing the problem. Also the possibility to enter an email address to…

  17. Export Geotiff

    It doesn't seem like it's possible to obtain a world file for the original image any longer. This is disappointing, as it prevents use of the georeferenced result without an internet connection. It also prevent things like using the image in processes that might automate the extraction of data, etc...

  18. enable anonymous viewing

    Allow read-only access to the results. Sometimes I want to send a link to someone - either "View in 3D", "OGC WMS in OpenLayers" or "Accuracy via MapAnalyst". It should be possible to view all of them without logging in.

  19. to give me a chance to get my password back and send the activation eMail again, because it did not appear in my inbox!

    I want to register, but I did not get an activation E-Mail. Now I do not even have the chance to contact anybody. That is bad!
