The first edition of this field guide was published in2009 and has been used by a broad spectrum ofhumanitarian and development organisations seekingpractical and low cost ways to exploit geospatialmethods in their work. In response to demand,MapAction is delighted to issue this second edition.Several chapters are expanded to meet users’ requestsfor more detail, particularly on where to find map data. Also, the Guide nowgives step-by-step guidance on the use of Quantum GIS (QGIS), an opensource software toolkit that has gone from strength to strength in its reliabilityand appropriateness for field use.
