Week 5- Plunkett

Chapter 6:


> Domains provide a way for you to constrain input information by limiting the choice of values for a particular field

> Using domains maintains data integrity- does not allow other values to be added during data collection 


Chapter 7:

> The process of creating map features from addresses, place names, etc. is geocoding. 

> To geocode addresses, you need an address table, reference data, and an address locator


Chapter 8:

> In the first exercise, I created a kernel density to see where areas of high density may occur.

> Kernel density: the density calculated of point features around each output raster cell 

> Temporal data represents a state in time


Chapter 9: 


> Rasters are composed of a grid of cells instead of x, y coordinates

> Used to define and record geographic phenomena 

> The reclassify tool is used to replace raster cell values with new cell values so that the rasters can be combined

Chapter 10:


> Dynamic labels are created when ArcGIS places labels for features in a layer with one click based on predetermined labeling rules.

> Useful for most mapping projects, but label positions can change depending on map scale
