Mosme

Mosme has four touch tools. Other tools and Solar need a mouse.

Assign addresses

Shape buildings

Clean up

One click

Circle radius

Settings

Theme

A theme change reloads the app.

Imagery

Imagery source

The Imagery switch on the map, or M, shows or hides the source.

Stored Ontario imagery limit, MB

Enter a whole number between 50 and 10000, or leave blank for 500 MB. Changes save at once. One MB is 1,000,000 bytes.

Ontario tiles stay for up to 90 days. The size limit is per browser. Mosme still needs an internet connection.

OpenStreetMap

OAuth client ID for openstreetmap.org

Optional. Leave blank to use the default. Change it to use your own OSM application.

Redirect URI to register:

Building outlines

Tag for drawn buildings, building=

Searched areas

Import merges marks and never deletes them. Import reads the file in this browser. Nothing is uploaded.

Solar

Estimated power per area, W/m²

Enter a positive value or leave blank for 140 W/m². The estimate uses the mapped panel area and never uploads to OSM.

Show the Merge mode

Off by default. When on, Solar's mode bar shows Merge, which combines the existing areas of one installation into one. It changes no geometry.

Save applies the OAuth client ID, building outline and Solar fields. Theme, imagery and experimental feature changes apply at once.

Experimental features

These features may change or go away. Each one applies as soon as you change it.

Pre-fetch imagery mode

Off by default. When on, Ontario imagery does not load as you pan. You select the areas you need, and Mosme downloads them one after another at the imagery zoom levels you map at. The map shows imagery only inside those areas, and you delete an area when you are done. The stored imagery limit and the 90 days in the Imagery card apply to the automatic mode only.

Show the Survey mode

Off by default. When on, Solar's mode bar shows Survey, which shows an area one tile at a time so you can tap each solar installation that OSM is missing. On a phone or tablet, the page reloads, and Solar opens in Survey with no mode bar, because Survey is its only mode there.

Keys

W: Switch workspace. Queued edits stay and unfinished drafts cancel.
M: Show or hide the imagery. Drafts stay open.
Shift + M: Adjust the imagery offset. Drag the map or press the arrow keys to move the imagery in 0.25 metre steps. Zoom waits during a drag. Esc, Enter or Done finishes. Tools and map panning wait until then.
U: Upload. A dialog says what goes up. Enter confirms and Esc cancels.
B: One click: click an address to queue its assignment to the highlighted building. The app picks the building with the most area inside the circle.
D: Sweep: hold the button and drag the circle across addresses. Each address goes to the building the circle covered most when the address was nearest its centre. Space and a drag pans the map.
T: Two clicks: click an address, then its building.
X: Split: click a building, type the number of pieces, drag the cuts, then Enter or X again.
C: Cut: drag between two corners to cut a building.
A: Draw building: click each corner, then click the first corner or press Enter. The app squares the outline and queues it as building=yes, or the value you set in Settings. Backspace deletes the last corner.
I: Parallelize holes. Turn each hole about its centre to the walls of its direct outer ring.
E: Edit outline: click a building, drag a corner or a wall's middle handle, then Enter or E again. The app squares the outline when you queue it.
I: Remove interpolation: click an address interpolation line to queue its removal. The line turns purple until you upload it.
2 to 9, + -: While splitting, the number of houses per row. This puts the cuts back at equal widths.
Shift + 1 to 9: While splitting, the number of rows, for back-to-back townhouses. This puts the cuts back at equal widths and depths.
R: While splitting, turn the cuts 90 degrees.
Drag a cut: Move it parallel to itself. Focus a handle and use the arrow keys to move it by 0.25 metres, or hold Shift for 1 metre. Esc during a drag restores its previous position. Reset cuts restores the suggestion. Shift and drag across the building adds a cut at any angle. Delete deletes the cut under the pointer.
Drag an outline handle: While editing an outline, a corner handle moves that corner and a wall's middle handle adds a corner there. Delete deletes the corner under the pointer.
[ ], Shift + wheel: Change the circle radius for One click and Sweep.
Tablet: Tap where you would click. Drag one finger to sweep or to move a cut or an outline handle, and two fingers to pan and zoom. The floating map buttons do what Enter, Esc, Backspace and Delete do.
Map keyboard cursor: Use Skip to map, then arrow keys to move the cursor. Shift moves farther. Space applies the tool. Enter also applies One click, Two clicks and Remove interpolation. Sweep starts and finishes with Space. Draw building adds corners with Space and finishes with Enter.
Ctrl + Z: Remove the newest queued edit: an assignment, sweep, split, cut, interpolation removal, drawn building or outline edit.
Esc: Cancel the first click of two, the split, the building you are drawing, or the outline edit.

W: Switch workspace. Queued edits stay and unfinished drafts cancel.
M: Show or hide the imagery. Drafts stay open.
Shift + M: Adjust the imagery offset. Drag the map or press the arrow keys to move the imagery in 0.25 metre steps. Zoom waits during a drag. Esc, Enter or Done finishes. Tools and map panning wait until then.
U: Upload. A dialog says what goes up. Enter confirms and Esc cancels.
A: Draw the areas of a new installation in Replace or Add.
T: Toggle Track searched area in Add.
N: Centre the map on the nearest solar node, when no installation is open. It passes over skipped nodes.
S: Skip the solar node under the pointer, or restore it if you skipped it. Skips stay in this browser.
Click the map: Place a corner of the panels. A click on the first corner closes the ring. After a ring closes, a click starts another ring.
Space: Place a corner at the pointer.
Enter: Close the ring you are drawing. Closing a ring squares it. With no ring open, queue the installation. While drawing a building, close it. Otherwise, while you edit a building outline, finish the outline and go back to the installation.
Backspace: Delete the last corner of the ring you are drawing, or the selected corner.
Delete: Delete the selected corner.
D: Draw a missing building for the open installation. This enters Building outline mode. Close or delete any open ring first.
O: Edit the outline of the building under the installation, or go back to the installation.
P: Parallelize. Turn each outer ring and its descendants about the outer ring's centre to the walls of the building under it. A ring over no loaded building lines up with the other rings.
I: Parallelize holes. Turn each hole about its centre to the walls of its direct outer ring.
E: Equalize. Give every rectangular ring the median thickness of those rings.
Q: Square ring. While it is on, a click on a closed ring squares it again. Q or Esc turns it off.
R: Repeat last array. A copy of the newest ring follows the pointer by its top left corner, and each click places one. A hole copies as a hole. R or Esc turns it off.
C: Copy array. Click a ring to copy, then each click places a copy. A hole copies as a hole. C or Esc turns it off.
Ctrl + Z: While an installation is open, undo the last Parallelize, Parallelize holes, Equalize, Square ring, placed copy or building outline squaring.
Click a solar node: Select it for replacement by the new installation, or deselect it.
Tab, arrow keys: Focus a closed corner and move it one screen pixel. Hold Shift to move ten pixels.
Drag a handle: A corner handle moves that corner and a wall's middle handle adds a corner there. A click selects a corner.
Esc: Turn off Square ring, Repeat last array or Copy array, or cancel the installation.
Ctrl + Z: When no installation is open, remove the newest queued installation.
