ArcGIS Pro & QGIS Final Test

Which tool in ArcGIS Pro would you use to aggregate point data based on a specific distance, and generate polygons representing those clusters?

• Kernel Density

• Convex Hull

• Aggregate Points

• Cluster and Outlier Analysis

When performing a supervised classification in ArcGIS Pro, which of the following steps comes immediately after collecting training samples?

• Image Rectification

• Signature File Creation

• Raster Resampling

• Accuracy Assessment

In QGIS, you want to perform a proximity analysis to calculate the distance from each point in a dataset to the nearest road. Which tool would you use?

• Distance Matrix

• Nearest Neighbor Analysis

• Buffer

• Voronoi Polygon Generator

To model stream networks from a DEM in ArcGIS Pro, which sequence of tools should you use?

• Fill, Flow Direction, Flow Accumulation, Stream to Feature

• Watershed, Buffer, Flow Accumulation, Slope

• Interpolate, Stream Link, Raster Calculator, Slope

• Spatial Analyst, Flow Direction, Cut Fill, Reclassify

In QGIS, what is the primary difference between using the 'Dissolve' tool and 'Merge Vector Layers'?

• Dissolve removes all attribute data while Merge combines geometries.

• Dissolve eliminates internal boundaries between features with shared attributes, whereas Merge combines layers without removing boundaries.

• Dissolve merges multiple layers while Merge works only on one layer.

• Dissolve creates multipart geometries while Merge converts them to singlepart geometries.

You have a large vector dataset in ArcGIS Pro, and your goal is to find all features within a 500-meter radius of a specific point. Which tool would you use?

• Select by Location

• Buffer

• Near

• Generate Service Areas

In QGIS, how would you extract the values of raster data to vector points, so that the raster values are added as attributes to the point features?

• Zonal Statistics

• Raster Calculator

• Sample Raster Values

• Point Sampling Tool

Which ArcGIS Pro tool should you use to find the optimal route between multiple locations while considering real-world obstacles like restricted zones or elevation changes?

• Service Area Analysis

• Trace Network

• Network Analyst: Route

• Cost Path Analysis

In QGIS, you need to create a heatmap to show the density of incidents across a city. What tool should you use?

• Kernel Density Estimation

• Point Cluster Tool

• Heatmap (Kernel Density Estimation)

• Inverse Distance Weighted (IDW) Interpolation

When applying a 'Weighted Overlay' in ArcGIS Pro for a site suitability analysis, what does adjusting the weight of each layer allow you to control?

• The importance of each criterion in the final suitability score

• The precision of the output raster cell size

• The type of classification method applied

• The geostatistical method used for interpolation
