Koenji Using ARCGIS Online to explore a place ArcGIS Online is a GIS program that can be opened at http://www.arcgis.com/home/ You can click on ‘Sign-up now’ or ‘Make a map’ to get started. It is free to use the program but there is also the option to take out an annual subscription to access some ways in which the program works. ©Teaching Geography Spring 2014 Martin Introduction – using the resource This resource has been written to provide ideas for classroom use in relation to the My Place article in Teaching Geography Spring 2014 edition. This article describes living in Koenji, a relatively small and densely built up district on the western part of Tokyo. The resource makes use of the online ArcGIS Online program. The ideas can be applied by using the program’s resources, tools and functions to the study of any place of a similar scale. Although written in the format of a pupil worksheet, the resource is intended mainly as a guide to help teachers work with the program. It is intended that a teacher will edit the resource to make it appropriate for the pupils they teach. Data and information in the form of maps, photos and text have been assembled from a variety of online sources to create this resource. It is, however, important to appreciate that the ArcGIS program is ‘open’, i.e. users can use it to create their own resources on any geographical topic. An option would have been to show how these resources were assembled, though this has not been done in this instance. Instead, the focus has been on showing how the user can use the resources, tools and functions to gain a knowledge and understanding of the Koenji district. Some resources have been included that are not specifically referred to in the work sheet activities, e.g. a map of the Prefectures in Tokyo. These are to enable the user to take the topic further if required. Individual teachers and pupils are able to use the ArcGIS program for free from their own home. A teacher can also use the program as part of a presentation in the classroom. For use in a school involving networking and file sharing, it will be necessary to pay the program’s annual subscription. ©Teaching Geography Spring 2014 Martin The Koenji map resource .
