FREE GIS for Engineering (MCQ) Questions and Answers
Which three kinds of models are possible to generate when creating a schema?
Three different kinds of models can be produced during schema generation: physical, logical, or metadata models. A physical model depicts the database's true structure, along with all of its metadata. The database's real structure, including its tables, columns, and relationships, is represented by a physical model. A logical model centers on the organizational and structural needs of the data as well as the business requirements. It operates without reference to any particular database management system. Data attributes including source, format, and meaning are captured by metadata models. Effective data management and comprehension are made possible by these models.
Which Data Frame Properties tab, according to figure 1-21, lets us select the map's coordinate system?
The response that corresponds with figure 1-21 is "Coordinate system." The Coordinate System tab in the Data Frame Properties gives us the option to select a coordinate system for the map. By choosing the coordinate system that best fits our map data, we can ensure accurate spatial representation and analysis using this tab.
Which map data within the installation border includes utilities, physical features, and facilities?
Map data that contains physical elements, utilities, and facilities inside the installation perimeter makes up the Common Installation Picture (CIP). It offers a thorough perspective of the installation, facilitating efficient resource management and planning. For coordination and decision-making inside the installation, the CIP is an invaluable instrument.
Which of the three files produced during the schema creation process has importation instructions?
The answer provided, readme.doc, is not accurate. The query asks which file has import instructions for the schema, while readme.doc has nothing to do with import instructions for the schema. Since the file in question most likely contains generic documentation or instructions on the schema rather than instructions particular to importing it, the right response cannot be ascertained using the choices provided.
What is the term for the relationship between an image's size and the quantity of grids per unit?
The ratio of an image's size to its number of grids per unit is called resolution. It is frequently expressed in terms of dots per inch (DPI) or pixels per meter and is used to characterize the sharpness and detail of an image.
Which of the three panels in the extensible markup language (XML) file import wizard lists name conflicts?
There are three screens in the XML file import wizard: Page 1, Page 2, and Page 3. Which window lists name conflicts is the question. Given that name conflicts usually arise during the import of XML files, it makes sense to believe that Page 2 is the window in which these conflicts are displayed.
Which kind of geodatabase allows for the presence of several editors—but only if they each work on a separate subset of the data?
Multiple editors can operate on different areas of the data at the same time with a file geodatabase. This indicates that as long as they are working on separate database features or sections, multiple users can change the data in the file geodatabase. This makes it possible for people to update and alter the data together without running afoul of one another's edits or conflicts. Multiple editors may be permitted in enterprise, Microsoft, and personal geodatabases; however, they are not subject to the same limitation of working on distinct portions of the data.
Under "Import," in the geodatabase context menu, which tool do we use to import a schema?
The XML workspace document is the right response. An XML workspace document is the tool used to import a schema in the geodatabase context menu. The schema information for the geodatabase, which includes feature classes, tables, relationships, domains, and other geodatabase features, is contained in this document. It is simple to move or share the schema between several geodatabases by importing the XML workspace document.
Which three vector data type groups are there?
In vector data, there are three type groups: polygons, lines, and points. Points on a map denote distinct locations or features, like a single structure or a particular point. Roads, rivers, and boundaries are examples of linear features that are represented by lines. Areas or regions, such as land parcels, lakes, or nations, are represented by polygons. Despite being frequently linked to vector data, imagery is not one of the three type groupings.
Which tables provide distinctive features for the data?
The right response is "Attribute." An attribute in a database or spreadsheet refers to a particular feature or property of a data object. It offers distinct features for each input of data and is used to describe or classify the data. Tables with attribute data offer distinct qualities for every data set. Better organization and analysis of the data are made possible by attribute data tables, which offer comprehensive information on the numerous attributes or features connected to the data.
Which mission data set (MDS) best describes the installation's planning districts?
The "Land use" data set is the mission data set (MDS) that depicts the installation's planning districts. Information on the allocation and use of the installation's land for different purposes would be available from this data set. It would contain information on the many districts or zones that make up the installation as well as the particular land uses that are permitted in each zone. Effective planning and management of the installation's infrastructure and resources would require this knowledge.
