Investigation of earth and how its system works

Broad range of topics related to earth and its landscape

Mountain building Structure of earth

Erosion of continents Location of natural resources

Volcanoes, paleoclimate and evolution

Space-age science

Remote sensing data High performance computing and State of the art visualization.

Free Software

can be used, studied, modified, copied andredistributed either without any restriction or withrestriction allowed by the manufacture and generally

available without any charge (Subramanyam and Xia,2008).

Open Source Software (OSS)

that is available in source code under a software licensethat permits the users to study, modify, improve anddistribute to other users (Hauge et al., 2010)


4/15

Expansive

low resource settings i.e. low budget schools particularlysuch schools in the developing countries

Examples

ENVI, Autodesk, Intergraph, ArcGIS and ERDASIMAGINE


5/15

Its free!

To use and distribute Simple installation No licensing costs

It works

Fits common spatial data standards Broad functionality

Customizable

Often easier to learn than proprietary packages.


6/15

Geoscience teaching & learning

mainly involves spatial data (both raster and vector) management,

analysis, visualisation and mapping.

This is what the propriety software such as ArcGIS and Erdas Imagine are meant for.

Free and open source software also provides the same functionalities.

Categories of available free & pen source RS and GIS Tools

Desktop RS and GIS software

Spatial data management systems (SDBMS)

Spatial data viewers

Virtual browsers

Mapping applications


7/15

Integrated raster and vector design Import and export of widely used data formats Comprehensive set of image processing tools Orthophoto, image georeferencing, transformation

and mosaicing Advanced modeling and spatial data analysis 3D visualization with interactive editing for

optimal view findings

Rich projection and coordinate system library Geo-statisitical analyses, Spatial multiple criteria evaluation

May not support teaching and learning with all thefinesse of large, expansive system. However, can geta job done

Worth examining as an alternative to buying orusing complex software and costly data.

Offer a free access to test the range of capabilitiesand make sure that it is compatible with yourteaching and learning requirements.
