A workshop to develop the skills required to construct maps in Arcmap.
Presented by Neil Gray, Teacher-in-Charge, Columboola EEC, (EQ), August 2006.
To delete data from the unit, press the “FIND” button, highlight “WAYPOINTS”, press “ENTER”, to bring up the waypoint list. Press the “MENU” button to access the waypoint manager screen, highlight the “delete” option, press “ENTER” and then select “all symbols”, press “ENTER”. The unit will ask if you really want to delete all waypoints. Select “Yes”, press “ENTER”.
To delete tracks and routes from the unit, go to the main menu screen, highlight “Tracks”, press “ENTER”, select “Clear” on the track page, press “ENTER”, the unit will as if you really want to clear the track log. Select “Yes”, press “ENTER”. Any saved routes can be deleted by erasing the component waypoints.
The original GIS project at Columboola was based on mapping a small plot of land using digital maps and satellite imagery. Out at Columboola (Miles), quality digital maps and satellite images are next to non-existent, or they cost a lot of money to acquire. This made it next to impossible to deliver the intent of the original project.
There had to be a way to cheaply and effectively use GPS in the field and display the data as a quality map. The release of the DNR Garmin interface for Garmin GPS to Arcmap has revolutionised the nature of generating maps from field data, and its free availability means that even primary school students can now record the results of their field work as a quality map. Compare that to pencil and paper mud maps!
The Dulacca SS project required a term for the entire exercise, and only the map produced has been used here. The students produced a brochure including photos, information and the map for the surrounding major vegetation types. About 6 hours of class time was spent learning to use the GPS units, a day of field work, 1 full day to make the map and 6 weeks of timetabled class time to research and make the brochure.
The reserve map is the result of about 3 days of intensive field and Arcmap work. The result is infinitely better than the old hand drawn map and useful too. I can now project orienteering points onto the digital map and print individual course maps! The students use their GPS units to find each loaded waypoint in a rogaining style event and monitor the map screen to help claim a “find”. The GPS units track the students for every step that they take, and when this is downloaded to MapSource on their return, I can see the exact route taken on screen, as well as whether a waypoint was “found”. I can even print out the exact track that they walked on the map as a record of their achievement!
The GPS units and software have also been used in GPS orienteering in Yr 8, 9 & 10 HPE at Miles SHS, and in senior maths A in the mapping and surveying section of the curriculum. Columboola EEC now “owns” a geocache and caching is included in our curriculum.
GPS and spatial ICT’s have revolutionised the way geographic information can be used in the HPE, Maths, Science and SOSE curriculum areas out here in the Miles Cluster.The Final Word
