Contrib: Sakai Maps

Lead(s): Maarten van Hoof Roland Groen

Description:

The SakaiMaps tool integrates Google Maps into Sakai and allows users to define and browse points of interest (POI) on the map. Each POI has a name, a short description, a type and optionally a url with more information.

More info...

Key features

Users can create and edit their own POIs but can't edit those created by others unless they have sufficient privileges.

POIs are stored in the database on a per-placement basis: different instances of the tool on the same server each have their own collection of POIs.

The site maintainer can define POI types, which are shown in different colors on the map. Users can filter the POIs on the map by type so that only POIs of a certain type are shown.

Maintainers can define up to three different maps (a point and zoom level) that users can navigate to easily.

Future plans

Future plans include integration with the wiki tool: user will be able to select a wiki page as link for a POI.

Maps Tool Installation

The Maps Tool comes in binary or source distribution, the source distribution needs to be build from within the Sakai source tree, the binary distribution can be installed an existing Sakai installation directly.

Prerequisites

This manual assumes that you are familiar with installing, building, and running Sakai. You must be familiar with the concepts in the Sakai installation guide, which can be found at:

Of course, you need a Sakai installation to use this Sakai tool.

Installing from binaries

Downloading the binary package

The latest version of the maps tool binary package can be downloaded from the following locations. The packages are tested on sakai 2.2, sakai 2.3, and sakai 2.4.

2.2/2.3/2.4

0.9.3

mapstool-0.9.3-sakai-2.x.zip

Installing the binary package

The binary version of the tool must be unpacked in the Sakai installation root. We strongly advise you stop Sakai before installing, the tool contains a component that configures at Sakai startup. The maps tool does not require any changes to the Sakai configuration, except for the auto.ddl property enabled on the first run to create the database table, see the #database section for details. Users need to have administrator privileges or the specific Maps Tool administration permissions set to be able to set the Google Maps key in order to use the tool.

Installing from source

Downloading the source

Sakai

Version

Location

The sakai maps tool depends on the edia-sakai-utils, both the maps tool and the dependent util project can be found at the following locations:
(The source will be added to the Sakai SVN soon. For now, you can download the source in a zip file)

edia-sakai-utils

1.0.2

edia-sakai-maps (repository)

0.9.3

edia-sakai-maps (zip file)

0.9.3

Running the build

Both projects downloaded above must be placed in the source root of Sakai. If you run an entire build on Sakai, it will automatically be part of that build. But if the source tree has already be build, it can be build individually by running a build in the following order:

  1. edia-sakai-utils
  2. edia-sakai-maps

Of course, to do the build the Sakai target needs to be be used:

maven sakai

Maven 1.x and ibiblio

Note: the ibiblio repository has been restructured, and maven 1.x on *nix has trouble understanding the http return code 301 (moved permanently). For that reason, it might be necessary to add the following to the maven.repo.remote property in the build.properties located in the home dir:

http://repo1.maven.org/maven/

database installation

The Sakai maps tool makes use of one table, which is mapped by hibernate. Sakai needs to be started with the

auto.ddl=true

set in the sakai.properties on the first run of the maps tool to let hibernate create the required table for you.

  1. Hi Maarten/Roeland,

    I am new to Sakai and just have installed your maps component. I think this component really adds value in many ways. I am looking to it from a perspective to increase visibility to geographically distributed projects (i.e. sites). From this perspective i have 2 questions :

    1. At this moment you can create references that are local to a site. Do you think it makes sense to also allow for references that allow cross-site visibility? If possible at this point you are able to contact the owner of the site or at least make contac in some way.
    1. I do not know the standard capabilities of the google api. What for me is a powerful feature in google earth is the ability to click a reference and zoom-in to that location.

    Thanks, Freek

    1. Hi Freek,

      I'm not sure I understand your questions. If in 1. you ask if multiple maps tools in different sites will show each others markers: no, we have no plans to create that possibility. In the other 1. you don't seem to ask a question. Remember that Google Maps is not Google Earth.

      You should probably direct further questions to me or Roland directly.

      Thanks,
      Maarten

  2. Hi,

    Is SAKAI Maps compatible with 2.5.x?

    Bests regards.
