Preliminary Project Proposal:
If you are and undergrad in 11.188 or a grad student in 11.205 and continuing with 11.520, we need your preliminary project proposal submitted to Stellar TODAY.
This 'proposal' should be a tentative title plus a few sentences about one or more areas of interest for a short individual project on some spatial analysis topic of interest to you. Talk with us TODAY if you are unsure of your topic.
ArcGIS Help: 'Spatial Analyst' - Start with the 'Overview'
The exercise is more or less self-explanatory.
I'll demonstrate the first few steps of the raster manipulation tools - viz.,
setting up 100m gridcells for Cambridge and using these to convert the sales89
and cambbgrp layers to rasters.
Spatial Analyst: Setting up the grid cells and properties
explore 'options' values
after creating grid, zoom in to border and check edges
examine attribute table
After first IDW (inverse distance weighting)
compare with/without mask
note that attribute table is not visible for floating point grid values
note display does additional smoothing with contour-like thematic map
