User:Ndoiron/OfflineMap

Starting with the Map and MapStats Activities, and creating an offline map activity where users can view maps and add their own data.

Download Alpha from here: http://haiti.latest.disaster-tool.appspot.com/OfflineMaps.xo

Objectives

• Browse set of maps of Haiti, working offline ✓
• Ability to map a latitude,longitude point ✓
• Search by name of city to get closest view ✓
• Read in a KML (Google Earth) file of points ✓
• Search by content text ✓
• Create placemarks; add photos and text ✓
• Paste from OpenStreetMap or Google Maps when connected to internet ✓
• Add lines, allowing roadmaps
• Read in a KML file of points and lines
• Use XOL bundles to add additional maps / cities / data
• Share points between XOs ✓

Viewing Maps

Pre-loaded

Roadmaps of these areas come with the activity (CC-BY-SA OpenStreetMap).

• Lagonav Island
• Jacmel
• Leogane
• Jeremie
• Saint-Marc

Submeter aerial photos (NAVOCEANO)

• Gonaives (harbor area)

A USAID map is also included for:

• Port-Au-Prince

Loading a KML File

The more detailed USAID relief map of Port-Au-Prince appears on top of a Haiti roadmap. Instead of zooming in like this, it should be possible to click and "jump" to only the Port-Au-Prince view.

Just added Import KML - these are from MINUSTAH's list of hospitals (MINUSTAH is UN Mission to Haiti)

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

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 can be stored for the next time the user looks at the map.

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.

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.

Other Screenshots

This is a very clumsy beta version.

The latitude/longitude position of Jacmel is marked with a blue square. Clicking on the square reveals text information. The black square is a centering-mark for drawing additional lines.

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. If you have a purpose for 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.
