mapping techniques:
an educational resource
or just a breaking of conventions
(and the bane of your existence) ?

Knowledge management
what is this?
Students are requests to write a personal report after field work on:
- methods
- data capturing
- data elaboration
- pros and cons of tools, methods, experience
- suggestions and proposal
Students main PROS:
1 – capturing attention (more males - geeks)
2 – easy approach
3 – similar work as the analogic one, but better, because it push to
learn basics of GIS
4 – using different base maps (CTR and IGM maps, orthophoto,
thematic maps, aerial photos)
5 – possible use of forms (driven survey)
6 – unique storage of data (notes, photos, maps)
7 – development of technology allows lighter hardware
8 – working also with bad weather (when rugged was used)
9 – collaborative working
10 – good and faster elaboration
Students main CONS:
1 – difficult start with people not familiar with IT (elder students)
2 – bringing maps, fieldbook, pencils, etc is easier and cheaper
3 – fighting against technology: lost bluetooth connection, battery life
4 – procedure mistakes can destroy data, layers, files
5 – sometimes pre-arranged forms are difficult to use in the field
6 – weight of tools
7 – problems with weather and visibility when working outdoor
8 – survey must be pre-organised in the lab very carefully
9 – not every pc are good for this work (often they cannot buy a tablet PC)
10 – difficult elaboration when exporting to other software
Teacher PROS:
1 – capturing attention
2 – easier feedback
3 – very few notions must be transmitted before working
4 – learning by doing
5 – collaborative work can be assessed
6 – personal work can be recognised
7 – keeping records of all the work done during years
8 – testing the methods of digital mapping (using students as lab rats)
9 – open source GIS software is developed ad-hoc
Teacher CONS:
1 – difficult start with people not familiar with IT (difficult in teaching when alone)
2 – hardware become old very/too soon (expensive equipment for class)
3 – fighting against technology: lost bluetooth connection, battery life
4 – fighting with student laziness
5 – organise a digital field work is often heavy
6 – difficult elaboration workflow when exporting to other software
7 – open source GIS software is not developed continuously
