Chapter 3: Introducing the iD Editor

Objectifs d’apprentissage

  • Understanding iD Editor interface
  • Editing OpenStreetMap using the iD Editor
  • Saving and Uploading edits

You have succeeded on creating OpenStreetMap account and you’re eligible to edit OpenStreetMap. Now we will learn how to add your data and edit it using an editor that runs in the browser called the iD Editor.

iD Editor is a web based OpenStreetMap editor that allows you to add and make changes to the OpenStreetMap data easily and fast by using spatial data sources such as satelite imagerY, GPS, and FiledPapers.

3.1 STARTING ID EDITOR

Before you start, your computer must be connected to the internet. Open your browser, then go to OpenStreetMap website http://www.openstreetmap.org , log in to your account and zoom in to the area that you want to edit until the Edit menu is active. Click on the arrow sign next to the Edit ‣ Edit with iD (in-browser editor) as shown in the figure below.

../../_images/3_013.png Getting Help
  1. Information panel: At the very bottom of the image area, this panel shows some information such as those who have contributed map edits in this area, as well as attribution for imagery sources and other map data.

3.3 Setting the Map Background

  1. Before you start editing, you can change the map background. Now click on the layer button
../../_images/3_014.png
  1. Then a new panel will pop up like this:
../../_images/3_015.png

Background and brightness setting in iD Editor

There are several ways to adjust the background in iD Editor. They are:

  1. You can set the brightness of the satellite imagery by clicking on this box
../../_images/3_016.png

There are 3 brightness you can choose: 100%, 50%, and 0%. Try all of them to see the difference.

  1. You can also set the provider of satellite imagery depending on which one is available for your desired area (the standard choice is Bing Aerial Imagery). You can also set OpenStreetMap map as your background.
  2. Also, if you want to make a previously uploaded Field Papers to be your background, please click on the Custom choice and put the FieldPapers URL (for example: http://fieldpapers.org/snapshot.php?id=fdsbgzns#17/-6.20049/106.82533) on the column as seen below:
../../_images/3_017.png

Inserting Field Papers into iD Editor

  1. You can add your GPS tracks and waypoints that are saved on your computer (they must be in GPX file format). Just click on your GPX, hold, and drag it to the editor page.
  2. If there is a known satellite imagery offset, you can do a correction by clicking on Fix misalignment until a box seen below shows up:
../../_images/3_018.png
  1. You can set the correction by clicking on the navigation buttons
../../_images/3_019.png
  1. Click on
../../_images/3_020.png

to bring the imagery back to the initial position.

3.4 BASIC EDITING WITH ID EDITOR

Before we start practicing using iD Editor, first navigate to the desired area on the map that you want to edit. You can pan around the map by clicking on your mouse and dragging the map to your area of interest.

Adding a Point

To add a point feature, click on

../../_images/3_021.png

You will see the cursor change into a plus sign (+). Now, click on the object that you want to map. For example, you see a building on the map and you know that building is a hospital. Click on the building.

../../_images/3_022.png

Adding a point in iD Editor

Now, you can see there’s a new point. At the same time, the feature panel will be showing you attributes that you can choose depending on the object type. Now type Hospital on the Search section, and choose Hospital to add this feature to the map, as shown in the figure below.

../../_images/3_023.png

Adding information to a point in iD Editor

The point symbol will change automatically, and the feature panel will change into a form which can be filled with information about the hospital, such as the name of the hospital, the address, and other information about this feature.

Note

Features may have a different forms - points, lines, or polygons. It will depends on the type of the feature, the mapping scale, and the quality of imagery.

If you want to move the location of that point, you can click on the object then hold it and move it to the new location. If you want to delete the object, click on the object, a delete button will show up.

../../_images/3_024.png

Click on that button to delete the object.

Adding a Line

Click on:

../../_images/3_025.png

And again you will see the cursor change into a plus sign (+). Suppose you want to draw a road. To do this, first click at one of the ends of the road, then just move your cursor to and keep clicking along the way of the roads and follow it until a road line formed. Double click to end the line and the feature panel will appear again on the left side of the window.

../../_images/3_026.png

Adding lines in iD Editor

The feature panel will display some attributes for you to choose from, depending on the type of your line. You can also move the points in the line by clicking on a point and move it. The other thing you can do is move the line by clicking on it, holding down the mouse button, and moving the line. Also, when you click on a point (vertex) on the line, you will find some additional functions as shown in the figure below:

../../_images/3_027.png Deleting/removing the point from the line
../../_images/3_028.png Separating a point that is attached to other object.
../../_images/3_029.png Spliting a line into two different parts. It is useful when there are different attributes in a long line (For example, different road names)

Also, when you click on the line (in between points), you will find additional functionality as shown in the figure below:

../../_images/3_030.png Removing the line
../../_images/3_031.png Forming the line into a circle
../../_images/3_032.png Moving the line position
../../_images/3_033.png Creating the angles of the line into right-angled line
../../_images/3_034.png Reversing the line direction
../../_images/3_035.png

Adding an Area (Polygon)

To add an area, or polygon feature, click on the button below:

../../_images/3_036.png

Again the cursor will change to a plus sign (+). Using the imagery as a guide, trace the area by clicking on the corners of the feature, as shown in the figure below.

../../_images/3_037.png

Adding area/polygon in iD Editor

As with point and line features, when you click on one of the point on the polygon, you will see additional editing functionality. Similarly, clicking on the line of the polygon (between points) will reveal additional editing operations available to you.

3.5 Saving your Changes

Click on the button below:

../../_images/3_038.png

to save your changes. Pay attention to the panel on your left side that will show something like this:

../../_images/3_039.png

Saving your changes in iD Editor

Fill in the Comment column with a brief note about the changes made in that area so that other users can note your edits. Then click Save.

3.6 Additional Attributes

When you add attributes to features, you can make the data more useful by adding more information. The icons shown in the figure below help you to add additional details to your map data:

../../_images/3_040.png Adding elevation information
../../_images/3_041.png Adding notes
../../_images/3_042.png Adding contacts/phone number
../../_images/3_043.png Adding sources
../../_images/3_044.png Adding website information
../../_images/3_045.png Add information on the availability of accessibility for people with disabilities
../../_images/3_046.png Adding Wikipedia links

Tags list on iD Editor

In addition, you can also add your own attributes by clicking on the icon

../../_images/3_047.png

This will raise a form allowing you to add your own attributes:

../../_images/3_048.png

Click on the + sign to add a key and value that you want. For guidance, consult the full list for key/value pairs here: Wiki OpenStreetMap Map Features

Summary

You should now be able to add your data to OpenStreetMap using the in-browser iD Editor. You also learned how to digitize the 3 types of objects in OpenStreetMap: points, lines, and areas (polygons). In the next chapter, we will learn about another editor, the Java OpenStreetMap editor, or JOSM as it is popularly known.
