GIS MCQ Quiz Questions And Answers

The three type groups of vector data are points, lines, and polygons. Points represent individual locations or features, such as a single building or a specific coordinate on a map. Lines are used to represent linear features, such as roads, rivers, or boundaries. Polygons are used to represent areas or regions, such as land parcels, lakes, or countries. Imagery, although often associated with vector data, is not one of the three type groups.

The correct answer is Attribute. In a database or spreadsheet, an attribute refers to a specific characteristic or property of a data object. It is used to describe or categorize the data and provides unique characteristics for each data entry. Tables that contain attribute data provide detailed information about the various attributes or properties associated with the data, allowing for better organization and analysis of the information.

A file geodatabase allows multiple editors to work on different parts of the data simultaneously. This means that multiple users can edit the data in a file geodatabase, as long as they are working on different sections or features within the database. This allows for collaborative editing and updating of the data without conflicts or overwriting each other's changes. Personal geodatabases, Microsoft databases, and enterprise databases may also allow multiple editors, but they do not have the same restriction of working on different parts of the data.

The editor function that allows us to specify an angle and a length to create a line or side of a polygon is Direction/Length. This function allows us to input both the direction or angle at which the line should be created, as well as the length or size of the line. By specifying both the direction and length, we can accurately create lines or sides of polygons with the desired dimensions and orientations.

Resolution refers to the ratio of the size of an image to the number of grids per unit. It is commonly used to describe the clarity and detail of an image, and is often measured in terms of dots per inch (DPI) or pixels per meter.

Mathematical models that translate between coordinate systems are called transformations. Transformations involve converting points or objects from one coordinate system to another, often by applying a set of equations or rules. This process allows for the representation of the same object or point in different coordinate systems, facilitating calculations and comparisons across different frameworks. Translations, on the other hand, refer to shifting an object or point in a coordinate system without changing its orientation or shape. Evolutions and declinations do not accurately describe the process of translating between coordinate systems.

When using the "Create Feature Class from XY Table" tool, we specify the X field, Y field, and Z field as the three input fields. These fields represent the spatial coordinates of the features in the feature class. The X field represents the horizontal position, the Y field represents the vertical position, and the Z field represents the elevation or depth of the features.

When converting a spreadsheet to a feature class, the file output must be located in a geodatabase. A geodatabase is a container that can store multiple datasets, including feature classes, attribute tables, and relationships. It provides a structured way to organize and manage spatial data, making it the appropriate location for the output file. Storing the file in an attribute table, compressed folder, or Microsoft Access database would not be suitable for converting a spreadsheet to a feature class.

The correct answer is "Coordinate system." In figure 1-21, the tab under the Data Frame Properties that allows us to choose a coordinate system for the map is the Coordinate System tab. This tab allows us to select the appropriate coordinate system that best fits our map data, ensuring accurate spatial representation and analysis.

Overlay analysis is a spatial analysis technique that combines multiple layers of data to create a new layer. It involves intersecting or uniting different datasets to identify areas of overlap or combine attributes. This process helps in understanding relationships and patterns between different datasets, allowing for more comprehensive analysis and decision-making. Therefore, overlay analysis is the kind of analysis that creates a layer comprised of intersected or united data.

When converting raster or image files, the process involves changing the suffix of the file. The suffix refers to the file extension, such as .jpg, .png, or .gif, which indicates the file format. By changing the suffix, the file format is altered, allowing the image to be saved or opened in a different format. This conversion process is commonly used when converting images between different file types or compressing them to reduce file size.

In order to adjust the size of the layout area and its orientation, we need to access the Page and Print Setup. This option allows us to customize the page size and select the desired orientation for the layout area. By adjusting these settings, we can ensure that the layout area fits the desired dimensions and is aligned correctly for printing or exporting the map. The other options mentioned, such as Export Map, Print Preview, and Printer Properties, do not specifically provide the functionality to adjust the size and orientation of the layout area.

The mission data set (MDS) that represents the planning districts of the installation is the "Land use" data set. This data set would provide information on how the land within the installation is being utilized and allocated for various purposes. It would include details on the different zones or districts within the installation and the specific land uses allowed in each zone. This information would be crucial for planning and managing the installation's resources and infrastructure effectively.

The Merge tool in Toolbox can be found under the Data Management list. This list includes various tools and functions related to managing and manipulating data, such as merging, converting, and editing datasets. The Merge tool specifically allows users to combine multiple datasets into a single dataset, either by appending or updating the data.

The names of items in a legend replicate the names of layers. In a map or a visualization, layers represent different sets of data or information that are displayed together. A legend is used to explain the meaning of the symbols or colors used in the layers. Therefore, the items in the legend will typically have the same names as the layers they represent, making it easier for viewers to understand the relationship between the layers and the corresponding information displayed in the legend.

Enumeration is the correct answer because it refers to the process of assigning a unique identifier or number to each object within a feature class. This allows for easy differentiation and identification of individual objects within the same class. Emulation, explanation, and type coding are not relevant to the concept of differentiating objects within a feature class.

The correct answer is multiple buffer rings. When creating buffers, we have the option to create multiple rings instead of just one. This means that we can create several concentric rings around a feature, each with a different distance. This allows us to analyze the data within different buffer zones and observe any patterns or trends that may exist at varying distances from the feature.

When generating a schema, we can create three types of models: physical, logical, or metadata. A physical model represents the actual structure of the database, including tables, columns, and relationships. A logical model focuses on the business requirements and how the data should be organized and structured. It is independent of any specific database management system. Metadata models capture information about the data, such as its source, format, and meaning. These models help in understanding and managing the data effectively.

The coordinate system information is stored in the .prj file of a shapefile. This file contains the details about the projection, datum, and other spatial reference information associated with the shapefile. The .shx file is the index file that allows for faster access to the geometries in the .shp file. The .shp file contains the actual geometry data of the shapefile, while the .dbf file stores the attribute data associated with the shapes.

Catalog views and treats multifile shapefiles by grouping them together as a single file. This means that all the individual parts of the shapefile, such as the .shp, .shx, and .dbf files, are treated as a cohesive unit. This allows for easier management and organization of the shapefile, as it can be accessed and manipulated as a single entity rather than multiple separate files.

To create a new file of a layer's data in a different format, we use the "Export Data" tool. This tool allows us to convert the data from one format to another, making it compatible with different software or systems. It enables us to extract the layer's data and save it as a separate file in a format of our choice, such as CSV, shapefile, or geodatabase. This process helps in sharing or using the data in various applications or platforms that require a different file format.

The subtype functions in a geographic information system program are located in the Toolbox.

The two settings that adjust the quality of the output image in the "Export Map" window are Output Image Quality and Resolution. These settings determine the level of detail and clarity in the exported image. Output Image Quality refers to the overall visual appearance and fidelity of the image, while Resolution determines the number of pixels per unit of measurement, such as dots per inch (DPI), resulting in a higher or lower level of detail in the image.

The correct answer is XML workspace document. In the geodatabase context menu, the tool used to import a schema is an XML workspace document. This document contains the schema information for the geodatabase, including feature classes, tables, relationships, domains, and other geodatabase elements. By importing the XML workspace document, the schema can be easily transferred or shared between different geodatabases.

When exporting a .dwg to a shapefile, by default, five shapefile types are output. This means that the .dwg file will be converted into five separate shapefiles, each representing a different type of geographic feature. These shapefile types can include points, lines, polygons, and other spatial data elements.

The correct answer is pyramids because pyramids have a three-dimensional shape that allows us to group grids together at larger scales. The other options, such as cylinders, polygons, and diamonds, do not have the same shape or structure that would be suitable for grouping grids together.

A two-way relationship between data tables means that there is a connection or association between the tables where information can be shared and accessed in both directions. This suggests that the tables are related to each other, indicating a relationship between them. The term "relate" accurately describes this type of connection between data tables.

The toolbar that has tools for creating graphics, as opposed to vector data, is the Draw toolbar. This toolbar provides various tools such as shapes, text, and symbols that can be used to create and manipulate graphics within a software or application. The Edit toolbar, on the other hand, is typically used for modifying existing vector data, while the Georeferencing and Advanced Editing toolbars serve different purposes and are not specifically focused on creating graphics.

The Buffer Wizard tool allows the most control over the buffer process. This tool provides users with the ability to define the distance and units for the buffer, as well as the option to dissolve overlapping buffers. Additionally, the Buffer Wizard allows users to select specific features or layers to buffer, giving them more control over the process. The Map Buffer tool and Proximity Manager do not offer the same level of customization and control as the Buffer Wizard. The Analysis Tool is a vague option and does not specifically mention buffer processes.

"Least cost routing" refers to the process of selecting the most cost-effective path for data or voice transmission in a network. This analysis considers factors such as distance, capacity, and cost to determine the most efficient route. The term "least cost routing" is often used interchangeably with "network analysis" because it involves analyzing the network infrastructure to identify the optimal routes. Therefore, the correct answer is "Network."

The given answer, readme.doc, is incorrect. The question asks which file contains instructions on importing the schema, and readme.doc is not related to schema import instructions. It is likely a file containing general documentation or instructions about the schema, but not specifically about importing it. Therefore, the correct answer cannot be determined based on the given options.

To save a georeferenced image as a new file, we need to select the "Rectify" option. This is because the "Rectify" function in georeferencing tools allows us to apply the spatial referencing information to the image and save it as a new file with the corrected georeferencing. The other options mentioned, such as "Save," "Stop Editing," and "Update Georeferencing," do not specifically refer to the process of saving a georeferenced image as a new file.

The question asks which of the given options is NOT an output field when performing a statistical analysis. Sum, Count, and Frequency distribution are all commonly used output fields in statistical analysis. However, Integral deviation is not a standard output field in statistical analysis. It is not a commonly used measure and is not typically reported as an output in statistical analysis. Therefore, the correct answer is Integral deviation.

The import wizard for XML files has three windows: Page 1, Page 2, and Page 3. The question asks which window lists name conflicts. Since name conflicts typically occur when importing XML files, it is logical to assume that the window where these conflicts would be listed is Page 2.

The program ranks options in the "Using" dropdown list based on their suitability, with the most suitable option being placed on top.

The “Export Data” window in most data handling software typically asks for the Format (what type of file to export as), Output location (where to save the exported file), and Features to export (which data to include in the export). However, it usually does not ask for the Coordinate system. The Coordinate system is typically inherent to the data being exported and is not something the user needs to specify during the export process. So, the correct answer is D. Coordinate system.

The Description tab in Catalog displays the metadata of an item. Metadata provides information about the item, such as its title, author, date created, and keywords. This tab allows users to view and edit the metadata associated with the item, providing a detailed description and context for the item's content.

The "Metadata Style" setting can be found under the "Customize" menu in ArcCatalog Options.

The Common Installation Picture (CIP) comprises map data that includes facilities, physical features, and utilities within the installation boundary. It provides a comprehensive view of the installation, allowing for effective planning and management of resources. The CIP is a valuable tool for decision-making and coordination within the installation.

The first topology rule for vector data listed in the text is that features terminate at proper nodes. This means that the endpoints of lines or boundaries of polygons should be connected to other lines or boundaries, and there should be no dangling or unconnected nodes. This rule ensures that the vector data is properly connected and avoids any gaps or overlaps in the features.
