Let´s start mapping

For your first mapping with iD editor it is very useful to complete the provided Walkthrough (Fig. 21). The walkthrough will explain how to navigate around the map, how to zoom in and out and how to mark points, areas, lines and building into the map. When you are familiar with mapping these features, you are ready to move on to mapping the real objects. Click “Start Editing”.

Setting the imaginery

First of all, it is very important to set the imaginery according to previous instructions. In this case, we need to set imaginery for “Maxar Premium Imagery” (Fig. 22).

Finally mapping

You are ready to map! Zoom in so you can see the features clearly.

• Click to “Area” to start mapping the buildings.

• Start by clicking on the corner of the building and continue to mark other corners. By clicking on the last corner again you can finish the process. Walls of the building will be red (Fig. 23).

Selecting feature type

Now it’s important to select a feature type. This window will pop-up automatically after marking the building (Fig. 24):

• choose “Building” as a feature type

Squaring the corners

After selecting the feature type you can square the corners of the feature by pressing “Q” on your keyboard (Fig. 25). All other useful shortcuts are visible after clicking on the map with right-click (Fig. 26).

Saving the changes

That’s it! After finishing the mapping you can save your changes and upload them to OpenStreetMap (Fig. 27).

• Click „Save“ - the window with Changeset Comment and Hashtag will pop-up (Fig. 28)

At the bottom (Fig. 29), there is an option of reviewing the edits. If you are unsure with your edits, check the box and let someone more experienced check your work. Click “Upload” and your changes will be added to OpenStreetMap.

Marking the stage of the task

After finishing your mapping session it is important to mark the stage of the task:

• if you mapped the task completely, check “Yes”

• if there are still some buildings left, or you are not sure, check “No”

• if you can not identify the buildings because of poor imaginery, check “The imagery is bad” (Fig. 30)

There is also a possibility of writing a comment about the task. If the task is too big and contains too much features, there is an option to split it and share with other participants by clicking „Split task“ (Fig. 31).
