User:Ndoiron/OfflineMap

Creating an offline map activity where users can view maps and add their own markers, photos, and information. It can serve as a powerful tool for Grassroots Mapping.

Viewing Maps

Pre-loaded maps

Roadmap: Port-Au-Prince, Lagonav Island, Jacmel, Leogane, Jeremie, Saint Marc, Port de Paix, Ile a Vache

Satellite: Gonaives, Grand Goave, Miragoave, Anse a Galets, Etroits/Matenwa area

Moving the Map

• You can use the control pad arrows to move the map.
• The + and - keys zoom in and out
• You can also double-click to zoom in on an area
• Search for a city name in the Find field, or a marker in the Tags field.

Making Maps

Create Markers, add Text

Add points to the map and add text and other information. Click the marker, and an information bubble appears. More technical users can use HTML. You can edit the description later.

These points appear on other XOs that share the activity.

Embedding your Photos

Photos, audio, and video made in Record can be placed onto the map.

Satellite photos of several cities' harbors are available from the USA's NOAA and NAVOCEANO.

Add Lines and Shapes

You can now add lines and shapes, and import files with lines and shapes.

To add your own line, go to the Edit menu and select the large / option. Click on the map to start making a line (the color is randomly selected). Each point will be marked by a large black square. You can continue to move the map with the control buttons while making the line. To finish, click the / option again. To make a shape, select the hexagon option.

Loading a Maps File

Import a maps file by selecting the "Add Media" button in the edit menu, and then locating the file on your USB drive. You can import points, lines, and shapes, along with descriptions and data, in a variety of formats:

• .kml (Google Earth and Maps)
• .rss (GeoRSS, such as latest reports from Ushahidi)
• .osm (OpenStreetMap.org)
• .xml (OfflineMap saved maps)

Many KML files can be found on GeoCommons. This example shows MINUSTAH's list of hospitals in Port-Au-Prince.

Loading these points on one XO will transmit their location to all XOs sharing the activity. The descriptions can be edited by any user.

Downloading new basemaps

In the Edit menu, there are two options to download the latest, more detailed map. Select OpenStreetMap or Google Maps, then use the + cursor to click where on the map to center your detailed map.

Adding from OpenStreetMap

When a user can connect to the internet, they should be able to add the most recent street map of where they are looking. Since OpenStreetMap uses a Creative Commons license, the image could be stored for the next time the user views the map (not currently enabled).

OpenStreetMap is the best roadmap of Haiti at present.

Adding from Google Maps

When online, a user can also add a small satellite photo from Google Maps. We are not allowed to store these images offline.

Other Screenshots

As with the Map activity, you can embed a Wikipedia article using codes such as wikiHT::Lagonav (il) and wikiFR::La Gonâve, but this requires internet access. If there is a WikiBrowse-Haiti in the works, it would be possible to link to those articles.

Other codes, such as img::file:///home/media/picture.jpg can also work if needed.

Haiti and Beyond

This activity is being developed as a general offline map of Haiti. To request offline maps of other countries, please contact me by editing this page or e-mailing ndoiron _at_ cmu.edu

There is interest in using the activity for disaster-response in Bangladesh, and conservation in Uganda.

Using XOL bundles would make it easier to quickly create, install, and switch between map sets.
