About the Test

This test includes questions on Data Management linked with GIS, spatial referencing and positioning which includes datums, coordinate systems, etc.

A GIS is a computer-based system that provides data capabilities to handle geo-referenced data. It is mainly used for capturing, storing, querying, exploring, analyzing, and displaying geospatial data. This computer-based system provides four sets of capabilities: data capture and preparation, data management, data manipulation, and analysis and data presentation. A GIS combines functional GIS software and hardware components, and users work on software and infrastructure support. GIS can be used in various fields such as Agriculture, Urban Planning, Disaster Management, Mapping, Navigation, Marketing, Geology, etc.

Customer Satisfaction

Testlify helps you identify the best talent from anywhere in the world, with a seamless experience that candidates and hiring teams love every step of the way.

1

Data Management

Data management in GIS (geographic information systems) refers to the processes and technologies used to acquire, store, manipulate, analyze, and share spatial data. GIS data management involves various activities, such as data acquisition, storage and organization, integration and interoperability, quality control, and dissemination. GIS data management is critical for ensuring that spatial data is accurate, reliable, and accessible and can be effectively used to support various applications and decision-making processes. GIS data management can involve the use of specialized software, such as GIS database management systems, and requires GIS professionals’ expertise.

2

Data display & maps

Data display and maps in GIS (geographic information systems) refer to how spatial data is visualized and presented to users. In GIS, data is often displayed using maps, which can visually represent the spatial distribution of data. Maps can be created using various GIS software tools and customized to show specific data layers and display options. GIS maps can include a range of features, such as labels, symbols, and legends, to help users understand and interpret the data. GIS data display and maps can support various applications, such as spatial analysis, planning, and decision-making.

3

Spatial Data Concept

The spatial data concept in GIS (geographic information systems) refers to the idea that data has a spatial component associated with a specific location on the Earth’s surface. In GIS, spatial data is typically represented as geographic features, such as points, lines, and polygons, which can be linked to attribute data that provides additional information about the features. The spatial data concept is central to GIS, as it enables the creation of maps and other visualizations that show the geographic distribution of data. GIS software tools are used to manage and analyze spatial data and support various applications, such as spatial analysis, mapping, and decision-making.

4

Spatial referencing and Positioning

Spatial referencing and positioning in GIS (geographic information systems) refers to the methods and technologies used to identify the locations of geographic features on the Earth’s surface. In GIS, spatial referencing involves assigning coordinates, such as latitude and longitude, to geographic features, and positioning refers to determining a feature’s location on its coordinates. Spatial referencing and positioning are critical for GIS, as they enable the creation of accurate and precise maps and other spatial data visualizations. GIS software tools are used to perform spatial referencing and positioning and support various applications, such as spatial analysis, mapping, and navigation.

The test is created by a subject-matter expert

Testlify’s skill tests are designed by experienced SMEs (subject matter experts). We evaluate these experts based on specific metrics such as expertise, capability, and their market reputation. Prior to being published, each skill test is peer-reviewed by other experts and then calibrated based on insights derived from a significant number of test-takers who are well-versed in that skill area. Our inherent feedback systems and built-in algorithms enable our SMEs to refine our tests continually.
