Part Four: It is always a matter of "IF".
We wrap up our GIS series today with the IF() conditional function. Using this function, we can perform some quick analysis on our GIS data and alter many aspects of how it is displayed and/or annotated.
The possibilities are infinite!
For example, when adding GIS data showing soil information, we could have poor soils automatically highlighted.
When adding GIS data containing parcel data, we could color every parcel red whose area is below the minimum standard.
When adding GIS data containing pipes, we could alter the pipe widths based on a diameter attribute…
If you couple this with the other tools we have looked at over the last several installments we can do some really cool stuff with GIS data. (And we haven’t even scratched the surface yet :) )
In our example today, we will review parcel data stored in a GIS file as it is inserted into our model. Any parcel that does not meet the minimum Area (12,000 SF) is automatically colored differently (red) than the others (light blue). This is accomplished using the conditional function IF().
Check out the video below to see how it works.
