Question

The figure below depicts four flowcharts of cartographic models to find areas

most suitable for a desalinization plant. Sites are preferred for which all parts meet all

of the following criteria:

At an elevation of 5 m or greater;

Within 0.25 km of the coastline;

All areas within 0.5 km of trunk water pipe;

Within a single parcel;

Areas larger than 100 ha.

Select the flowchart that best approximates the proper analysis, given the described

data. For each other flowchart, list at least one primary way it is more likely to lead to

an error. Note that some small intermediate steps are omitted for all flowcharts, so do

not cite a step omitted in both the best and alternate flowcharts

13.10-The figure below depicts four flowcharts of cartographie models to find areas most suitable for a desalinization plant. Sites are preferred for which all parts meet all of the following criteria: At an elevation of 5 m or greater; Within 0.25 km of the coastline: All areas within 0.5 km of trunk water pipe; Within a single parcel; Areas larger than 100 ha. Select the flowchart that best approximates the proper analysis, given the described data. For each other flowchart, list at least one primary way it is more likely to lead to an error. Note that some small intermediate steps are omitted for all flowcharts, so do not cite a step omitted in both the best and alternate flowcharts.

Explanation / Answer

c) It is the correct procedure for the given data to do in any software.At last dissolve tool is used to dissolve all the lines and polygon and at last >100ha is applied for parcel to show only the features greater than 100ha parcels.

A)In this option first only the parcel was divided with 100ha and at last the pipess option done and all the layers are intersected.It is also true but it results some minute errors.

B)Here also same done the large polygon was first clipped.

d)Here the raster elevation layer was not converted to vector elevation layer.
