The backlink raster is a cost direction surface created when you run the Cost Path tool.  False What are the units of measure for cell values in a Euclidean (straight-line) distance surface?  X The units you specify If you want the software to reclassify your raster values into new values based on a standard classification method, which of the following options would you use?  X Reclassify based on a table If you were trying to allocate cells in a raster to a source and determine distance and direction from each cell to the closest source, which single tool would you run to give you all these surfaces?  Euclidean Allocation Which tool allows you to write Python expressions to evaluate rasters or surface data?  Raster Calculator Euclidean distance tools can be used to determine horizontal distances between locations but cannot be used to determine vertical distances.  False 2 0 2 4 /2025 | © copyright | This work may not be copied for profit gain Excel! 1 | P a g e | G r a d e A + | 2 0 24 / 2 0 2 5 When creating any Euclidean surface, you have to determine the output cell size. What is a best practice when choosing an output cell size?  Choose a cell size that matches the data you already have so you do not imply more resolution than there really is. If you were performing a least-cost path analysis for building a new road through an established residential area, which of the following factors would be the most important in the analysis?  Property value Suppose that you used the Euclidean (straight-line) Distance tool and created a direction surface based on the location of regional airports. Each cell value in the direction surface indicates the direction to the nearest regional airport. Which cell value will correspond to the airport location?  0 Which of the following is a scenario where Euclidean distance would not be the best option?  Determining distance and route between two cities, taking speed limits and other factors into consideration. The type of surface created by the Euclidean (straight-line) Distance tool is a continuous surface.  True Which of the following operations gets all your rasters into a common ranking scale?  X Cost Distance X Euclidean Allocation 2 0 2 4 /2025 | © copyright | This work may not be copied for profit gain Excel! 1 | P a g e | G r a d e A + | 2 0 24 / 2 0 2 5 Which of the following is the correct workflow for performing least-cost path analysis?  X Reclassify and weight
