Activities/Map

The Map activity helps children to explore and create their own maps:

• Search for your school, the Statue of Liberty, or find Mongolia - see roadmaps and satellite photos.
• Write about what you see : add a description or embed a Wikipedia article
• You can take photos, video, or audio in Record and place them onto the map
• Use the XO's mesh network to collaborate, or save the map to the Journal
• Measure distance and area
• Participate in the online "OurMaps" wiki
• Advanced users add HTML and import KML (Google Earth), GeoRSS (Ushahidi), or OSM (OpenStreetMap) files

This activity needs your help to get out of Beta. Please edit this or the discussion page if you have a question.

Tutorial

Getting Started

Move the map using the compass arrows on the sides. Zoom in and out using + and - buttons, or double-clicking. Enter a location into the Find bar to jump to a new location.

Adding Text

You can add a text marker by clicking the i marker in the Edit section.

A text marker is shared with other XOs in your network. You can edit your own or others' text markers by clicking the marker and clicking the Edit button.

Adding Media

To add media from your journal onto the map, click on the Add Media button.

Select a photo, video, or audio file from the Record activity.

Your mouse will become a crosshair (+). Click the map to place the marker.

Adding Wikipedia and More

You can add images from the internet using the code pic::www.example.org/picture.jpg

You can add articles using a code such as wiki::Japan

For other languages: Spanish (ES.wikipedia.org) is wikiES::Barcelona and French is wikiFR::Paris

Other codes are google::OLPC to embed a Google search, and vid::www.example.org/video.ogg for OGG videos.

Saving Maps

You can save a map by clicking the star button. Saved maps are added to the tray at the bottom of the activity. If you click a map button, the map will be returned to the location and zoom level as when the map was saved.

Measuring Distance and Area

The new Measure feature can measure polyline distance or rectangle area. This is useful for geometry, surveying, or learning units.

Click the Ruler icon in the Edit tab.

Select Distance and click two points to begin measuring. When you are finished, click Done.

To measure Area, click opposite corners (for example, the northeast and southwest corners of Colorado)

Maps4xo Library

Click the Browse icon in the Edit Menu to view the library. This example uses the real-life use of GPS to track and protect turtles:

OurMaps Wiki

OurMaps is a wiki for storing or sharing map markers online.

When many markers are in one place, they are combined into a red "cluster" marker:

A marker can have an image or Wikipedia article embedded inside. This marker uses Simple Wikipedia's mobile site.

It is easy to create a marker and add to the map. A school can create a private group to collect markers that only they can see. A public group shares its markers with XO users around the world.

Development

The Map activity was written in PyGTK. It relies on JavaScript files to interact with Google's Static Maps API and geocoder.

Having the activity work on Sugar-on-a-Stick or emulators is an ongoing problem: http://www.youtube.com/watch?v=6QvMtQIqdfQ

You can download the source code in this zip file: http://maptonomy.appspot.com/Map-8.zip

All of the Map activity's code is under an MIT License.

Future Plans

• Detecting Sugar on a Stick systems and provide them with higher-res maps.
• More travel, history, environmental, and engineering example maps
