Viewing Maps

Pre-loaded maps

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

Satellite: Gonaives, Grand Goave, Miragoave, Anse a Galets

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 and area

Loading a KML File

You can import regular KML (Google Earth) files with points, lines, and shapes, along with descriptions stored in the file. Many of these 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.

Making Maps

Create Points, add Text

Add points to the map and add text and other information. More technical users can add HTML.

As with KML, these points appear on and can be edited by other XOs that share the activity.

Media Mapping with Record

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. Only Gonaives is pre-loaded.

Add Lines and Shapes

You can now add lines and shapes, and import KML 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.

Downloading new basemaps

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.
