EAPA_2025 Questions and Answers

The Range property allows dynamic filtering of features based on numeric attributes such as floor number. By setting the floor number as the range field, users can interactively slide through floors in a 3D scene.

Time (Option A) filters features based on temporal data.

Elevation (Option C) controls the vertical placement of features but does not allow interactive filtering by floor.

Therefore, the correct answer is B.

—

3D model marker symbology allows you to directly assign realistic 3D models (like campgrounds, facilities, buildings) to point features in a 3D scene without requiring a rule package. This makes it the most efficient and visually accurate option for realistic 3D representation.

Procedural marker symbology (Option A) requires rule packages.

Picture fill (Option B) applies to polygon fills, not 3D point feature symbology.

Therefore, the correct answer is C.

—

Definition queries limit the dataset used for both display and geoprocessing by applying SQL-based expressions to filter the data. This allows the GIS analyst to restrict all map display, analysis, and processing operations to only the records that meet the defined criteria (city and one-year period).

Display filters only limit what is visually shown but do not impact geoprocessing.

Zooming merely changes the map extent but has no filtering effect on data.

Definition queries fully restrict the dataset for both visualization and processing.

Therefore, the correct answer is A.

The Share tab in ArcGIS Pro contains all options related to exporting maps, layouts, and sharing data. Export Layout options for formats like PDF, PNG, and others are found here.

Project tab is used for application-level settings.

Map tab is for map design and editing.

Share tab includes all export and sharing options for layouts.

Therefore, the correct answer is C.

For categorical (classified) rasters such as land-use data, Nearest Neighbor interpolation must be used during resampling. This technique preserves the original class values without introducing fractional or interpolated values.

Cubic (Option A) and Bilinear (Option B) are interpolation methods suited for continuous data (elevation, temperature, etc.), but will distort categorical data.

Therefore, the correct answer is C.

—

TheSpatial Jointool in ArcGIS Pro allows specifying aMatch Optionthat defines how spatial relationships between feature geometries are evaluated. In this scenario, the target and join features are of different geometry types—Points (trees) and Polylines (power lines)—so the appropriate match options are based on proximity rather than containment or other spatial relations.

Within a distance: Matches features based on a planar search radius, ignoring elevation (Z-value), making it ideal for cases where all trees within a certain horizontal distance from power lines should be included, regardless of height.

Within a distance 3D: Includes vertical (Z) differences in the search, which is unnecessary here since tree height shouldn't affect inclusion.

Within Clementini: Refers to a topological boundary relationship and is only valid for comparisons involving polygons—not points vs polylines.

Thus, to includeall trees within a specified horizontal buffer of the power lines, theWithin a distanceoption is the correct one.

Time enabling a layer is done through the Layer Properties under the Time tab. This allows the analyst to specify the date-time field for use with the time slider, enabling temporal visualization directly in the map.

Map Properties (Option B) does not handle time configuration for individual layers.

Feature Class Properties (Option C) shows field details but does not enable time functionality.

Therefore, the correct answer is A.

—

A map frame is a container in the layout that displays any map or scene. To add a second map for additional context, the cartographer should insert a new map frame and choose which map it will display. This allows multiple maps to be shown together on the same layout.

Map view (Option B) refers to a separate view in the interface, not to the printed layout.

New layout (Option C) creates an entirely separate layout rather than adding to the current one.

Therefore, the correct answer is A.

—

The Feature Compare tool is designed specifically to compare two feature classes, examining multiple aspects including geometry, attributes, spatial reference, and schema structure.

File Compare is used for text file comparison, not for geodatabase features.

Table Compare evaluates attribute tables only, ignoring geometry and spatial reference.

Feature Compare performs a comprehensive assessment suitable for this scenario.

Therefore, the correct answer is C.

—

Many image services include multiple processing templates that provide different visualizations (e.g., slope, hillshade, aspect). The analyst can switch between these templates within the layer properties to access the various derivative products.

Changing band order (Option A) affects multi-band imagery but won’t expose separate processing templates.

Changing the source (Option C) changes the entire dataset rather than switching between available templates.

Therefore, the correct answer is B.

The Mosaic To New Raster tool merges multiple input raster datasets into a single raster dataset in a file-based format. This approach simplifies sharing and analysis because the result is a single raster file rather than a collection of rasters. Since all rasters have the same resolution and dimension, this tool is the most efficient solution for permanent combination.

Mosaic Datasets (Option A) are great for managing large raster collections but remain as collections, not single files.

Publishing tile layers (Option C) is primarily for web sharing, not file-based sharing or analysis.

Therefore, the correct answer is B.

—

Symbol scale determines the size of points when displayed. When LAS points appear too large, decreasing the symbol scale (making symbols smaller) will reduce the visual footprint of each point and prevent them from obscuring underlying map content.

Increasing point density (Option A) adds more points but doesn't reduce size.

Decreasing display limit (Option B) reduces how many points are drawn but does not solve the issue of size.

Decreasing symbol scale directly reduces the size of each point.

Therefore, the correct answer is C.

—

When you have selected features in a map layer and want to create a new dataset containing only those selected features, the proper workflow is to right-click the layer in the Contents pane, go to Data > Export Features. This process honors the current selection set and creates a new feature class based on that selection.

The Catalog pane (Options A and C) exports entire datasets and doesn’t apply the selection set directly.

Export Features (Option B) directly works with selected features and generates a new dataset from them.

Therefore, the correct answer is B.

ArcGIS Pro’sMatrix Heat Chartis designed for visualizing relationships between two categorical fields—such as origin and destination cities—and summarizing a numeric field, like delay time, using aggregate functions (e.g., mean). This type of chart aligns perfectly with the requirement:

It allows you to setColumnto the destination city andRowto the origin city.

Then choose theNumberfield as delay time and theAggregationmethod as "Mean" to calculate average delay.

The chart displays each origin‑destination pair as a cell, color‑coded by the calculated average delay.

Official documentation highlights this example explicitly:

“Create a matrix heat chart to identify the flights that have the highest average arrival delay time between origin and destination city by setting the following properties… Aggregation—Mean; Number—DelayTime”

Other chart types don’t fit the requirement:

Box plotis used to display distributions and identify outliers; it doesn’t aggregate by category pairs.

Scatter plotshows relationships between numeric variables on a continuous axis—not suitable for categorical city‑pair aggregation.

Therefore, the most appropriate choice for summarizing average journey delay by city pairs is theMatrix Heat Chart (C).

Mosaic datasets manage collections of multiple rasters, including discontinuous imagery, without physically merging the data. They allow users to query, subset, and download individual rasters on demand while maintaining a single logical dataset.

Raster dataset (Option A) stores a single continuous raster.

LAS dataset (Option B) is specific to lidar point cloud data.

Therefore, the correct answer is C.

—

The correct SQL expression should filter parcels that are both in the North region and where the OwnerName field contains 'Jon.' The LIKE operator is appropriate when matching patterns or partial names.

Option A correctly combines both conditions using AND.

Option B would include any parcel in the North region or any parcel where OwnerName contains Jon, which is overly broad.

Option C incorrectly uses exact equality, which would fail to match variations like 'Johnson' or 'Jonas.'

Note: The LIKE expression typically includes wildcard characters (e.g., LIKE '%Jon%') but based on provided options, Option A represents the correct logic.

Therefore, the correct answer is A.

—

Vertical coordinate systems always use linear units to measure elevation or depth (e.g., meters, feet). This differs from horizontal coordinate systems, which may use angular units (degrees) for geographic coordinates.

Angular units (Option B) apply to latitude and longitude in horizontal systems.

Direction units (Option C) apply to bearings or azimuths, not elevation.

Therefore, the correct answer is A.
