Oh dear sounds like a bit of a farce. They should maybe check that you can actually do exericises on uni computers first! Can you check with any other students on your course to see if they are having the same issue? You can use the 'Split Raster' tool to split the raster into either a user defined size or an equal number of parts. Have a go at setting the 'Split Method' to number of tiles then setting the 'Number of Output Rasters' to 3 in 'X Coordinate' and 3 in 'Y Coordinate' You will end up with the raster split into 9 tiles. Have a go at opening one of these on your computer. What is the ultimate aim of all this. Are you using surface modelling or hydrology tools in ArcGIS? ... View more

Hello Katie. To be honest I don't think compressing it is going to make the file size that much smaller. You're still talking several GBs of data. Is the file aerial imagery or a DEM? Some other options might be to find the file in ArcCatalog then either to lower the resolution using the 'Resample' tool or split is into several rasters using the 'Split Raster' tool. Failing that get in touch with your course lecturer and explain that you can't open the file on uni computers. ... View more

You could just have have a seperate Outline colour for each polygon and set the Fill Colour to 'no colour'. You could also have a play around with some different outline symbols. Click 'Edit Symbol' then 'Outline'. Another idea might be to look into animation to show how the boundary changes over time. ... View more
