Object-relational databases have become the cornerstone of modern GIS. These databases can be best described in which of the following ways:
Each database contains one table and one GIS layer
The database contains one attribute table for each GIS layer. The attribute table may contain numerous fields (attributes)
The database will contain many GIS layers, each with an attribute table. The attribute table may contain numerous fields (attributes)
The database will contain many GIS layers, each with an associated attribute table. In addition, other tables may exist that further describe specific characteristics of the GIS layer and are associated with the GIS layer through a relationship. Each table may contain numerous fields (attributes).
Calculations (sum, average, median, etc.) can’t be performed on this type of field

Which of the following industries knows raster graphic as contones?
Prepress
Printing

When converting Degrees/Minutes/Seconds of latitude in the Northern Hemisphere to decimal degrees
Add the three values together and divide the sum by 3600, i.e., (Deg+Min+Sec)/3600
Subtract the seconds from the minutes, then the minutes from the degrees i.e. (Deg-(Min-Sec))
Multiply the Minutes by 60, multiply the seconds by 3600 and then add all to the degrees, i.e., (Deg+(Min*60)+(Sec*3600))
Divide the Seconds by 3600, divide the Minutes by 60, then add those values to the degrees, i.e. (Deg+(Min/60)+(Sec/3600))
