Question

What steps should the GIS analyst take to ensure that the units in the distance field are as accurate as possible?

A) Convert all data to a different coordinate system
B) Use consistent linear units throughout the analysis
C) Ignore the units; they don't affect the analysis
D) Choose a different GIS software

Answer 1

A GIS analyst should use consistent linear units throughout the analysis (option B) to ensure accuracy in the distance fields, convert data if necessary, and verify results for unit consistency.

Step-by-step explanation:

To ensure that the units in the distance field are as accurate as possible in GIS analysis, an analyst should primarily use consistent linear units throughout the analysis. This involves making sure that all spatial data is in the same coordinate system with a common unit of measure, which could require converting data if they originate from different systems.


Additionally, the GIS analyst should verify that the GIS software is correctly interpreting the units, and should examine the final results to confirm that the units are reasonable and correctly specified within the data attributes. It's not advisable to ignore the units or choose different software without first ensuring the consistency of the units in the current system.
