Welcome to the Census Academy OpenMapping Series. This is module 2 of the OpenStreetMap
learning path, editing, and tagging with the ID editor. In this module you will learn the
basic steps to add a feature to OpenStreetMap, using the in-browser ID editor. You will use
aerial imagery to trace a building footprint, tag the object by adding a description of
the feature, learn how to compare OpenStreetMap data with Tiger data, and lastly add a change-set
comment and save your data to the map. With breaks for self-paced learning, you should
be able to complete this module in about 30 to 40 minutes. Two points to make before we
begin. Number one you will get more out of mapping if you use a mouse, it's very difficult
to map using a trackpad or a touchscreen. Second and most important, do not violate
the copyright by copying data from Google, Bing, MapQuest or any other proprietary map.
Part 1, the ID editor walkthrough. Start by logging into your OpenStreetMap account. Use
the nominated search box to find and zoom to an area familiar to you, note that you
will not be able to edit unless you're zoomed in sufficiently. Click Edit, from the top
of the screen and select the option for ID. You'll be presented with a choice of editing
now or taking the walkthrough. Let's take the walkthrough; the walkthrough will give
you a simple but comprehensive set of basic mapping techniques and should take you about
15 to 20 minutes to complete. Note that you can always recall this walkthrough from the
Help button on the right-hand side of the screen. Pause the video here and take the
walkthrough, resume when you finish the walkthrough. Now that you're familiar with the basic editing
techniques let's move on to part two, adding a building to OpenStreetMap. First, find your
area of interest by entering the familiar place name in the search box. Choose your
specific area from the list; this will Center the map in the general vicinity of your area
of interest. Then zoom to the neighborhood level by zooming to the neighborhood level
you ensure that you can clearly see individual buildings and other features as your map.
Once you've zoomed to the neighborhood level, click the edit button and select ID from the
list of options. This will call up the ID editor which works in the browser. In your
chosen area of interest find a building that is not on OpenStreetMap, it will appear on
the imagery, but it will lack an outline indicating that it is not on the map, because you're
adding a building footprint click area now, trace the building outline by clicking on
each corner of the building. Make your last click on the very first note to close the
area and complete your building. Then, square your building by right-clicking and selecting
the square icon from the context menu or by typing an S on your keyboard. Good, now you've
drawn a feature, the next step is tagging the feature as a building. For that we move
to part three, tagging your building. When we tag something on OpenStreetMap, we do two
things we give an identity to the feature we just drew, and we add descriptive characteristics
to that feature. Click on the building you just added, then in the left-hand pane, click
building features. Since we don't know what kind of building this is, we'll not attempt
to classify it. However, if you know something about this building such as name, address,
telephone, website, and so forth, add those in the pane on the left. Make sure you scroll
to the bottom of the panel to see all the applicable attributes for buildings. Pause
the video here, if necessary to examine the tagging
options for your building. Next, let's save your edits, near the top center of the screen,
click the Save button. In the box entered Changeset Comment, enter a short description
of your mapping activity. In this example, you may write
mapped my first building. This is also a good place to enter a hashtag, for example, hashtag
my first edit. We also strongly suggest ticking the box requesting a review of your edits,
particularly if you are a first-time mapper. Once you've entered your chain set comments,
click the upload button, which sends your updates to OpenStreetMap. Your edits should
be visible on the map in a few minutes. Congratulations, you've now contributed your first edit to
OpenStreetMap. Now let's move to part four, adding roads. The name OpenStreetMap implies
roads are a key feature on the map, in this part of the lesson we'll compare road coverage
between OpenStreetMap and the US Census Bureau's Tiger data, to ensure that roads are complete.
Tiger is a Geo data product of the US Census Bureau and consists of roads and other base
map features. For Open Street Map, Tiger can be an important source of validation in rural
areas and in rapidly changing landscapes across the U.S.
Why use Tiger? It is freely licensed, it aims to be consistent and complete for the U.S.
and territories, and it is updated annually. Now let's show you how to overlay, the two
layers to do this, position the map in an area familiar
to you and click the edit button to call up the ID editor open the layers control and
check the box for Tiger Roads 2017. Then zoom out until you see the red and yellow lines.
Roads from Tiger will show up as yellow; the red lines are roads in
Tiger that happens to be missing an OpenStreetMap. You can pause the video here,
to add the Tiger overlay and find some missing roads. When you resume, we'll add one of these
missing roads to OpenStreetMap. By now, you've found a red line, and you zoomed into it,
so it occupies the center of the screen. Since roads
are linear features, I'm going to click the line to add this road. Let's drop the first
node at the intersection with the existing road and continue adding points to trace the
path of the road. Double-click on the last point to end your tracing. It is important
to make sure your roads connect to the existing road network. So, snap your first node directly
on the existing road. Once you've added the road segment, move to the attribute pane,
and either search for road in the search box, or select Road features from the list. For
now, just classify the road as an unknown type or highway equals road. As a side note,
all roads and paths are classified as highways in OpenStreetMap, even foot trails. It's okay
to copy the road name from the Tiger overlay; census data
are public resources owned by the people and free to use in OpenStreetMap. You can save
your road to OpenStreetMap making sure you add a brief chain set comment, before you
upload. At this point, you should know how to digitize a
building, square its corners, and tag it with the appropriate building type. You should
also know how to add missing roads to OpenStreetMap, using the Tiger overlay. You're now ready
to proceed to the next module in the series, OpenStreetMap Module 3 using the OpenStreetMap,
Tasking Manager.
