Cartography and Geospatial Analysis

A sketch becomes a map when it has three formal elements: scale (so distances are measurable), direction (north arrow for orientation), and symbology (legend explaining what symbols mean). All three are required - a drawing missing any of these remains a sketch, not a proper map.

GIS's core function is integrating spatial data (maps, locations) with non-spatial data (attributes, statistics) to support decision-making. Surveying (A) is about measurement, photogrammetry (B) uses aerial photos to determine geometry, and GIS is not about doing 'all the above' - it has a specific purpose.

GPS is a satellite-based navigation system that provides location and time information anywhere on Earth. Option A describes GIS (Geographic Information System), which integrates spatial and non-spatial data for analysis. Option C describes remote sensing, which involves collecting data without physical contact. GPS is specifically for determining position through satellite signals.

For an internet application with a target audience in a specific geography, monitoring from nodes within that geography provides the most accurate representation of actual user experience. This captures realistic network conditions, latency, and performance that real users would encounter. Option A (same datacenter) gives optimistic results missing real-world network delays. Option C (worldwide nodes) includes irrelevant geographies and wastes resources monitoring regions where no users exist.

Aggregation is a "has-a" relationship where a whole is composed of parts, but the parts can exist independently. It's depicted with a hollow diamond at the container end. Unlike composition, aggregated parts have their own lifecycle and can belong to multiple wholes. For example, a Department aggregates Employees who can move to other departments.

A Mapset is a collection of one or more maps. In CICS BMS, maps are grouped together into mapsets for efficient management and loading. Individual maps are defined within a mapset. BMS is the overall system, while Physical Map and Symbolic Map refer to specific components, not collections.

For a geographically-targeted internet application, monitoring from nodes specific to that geography provides the most accurate measurement of user experience. Monitoring from the same data center doesn't capture network latency, and worldwide nodes may not reflect the specific geography's performance.

No doubt, rocks help to know the history of the earth through carbon dating method, but that is not a geographer’s area of study. Rather, geologists are interested and involved in exploring the history of the earth. Geographers are concerned with the study of elements and minerals that the rocks are made up of as these rocks, after disintegration and erosion, leads to formation of soils, which are important for geographers from agricultural point of view. Geographers are also concerned with the presence of various resources in association with the rocks.

These systems are used for management of the semi-structured spatial data represented in maps

Conventional symbols are standardized signs and markings used universally on maps to represent features like roads, rivers, buildings, and vegetation. These symbols (such as dotted lines for footpaths, blue for water, triangles for survey points) allow maps to be understood across different languages and cultures. A sketch is a rough drawing, alphabet refers to written letters, and thematic maps show specific data distributions but don't necessarily ensure universal understanding without conventional symbols.

A globe is the only representation that maintains accurate proportionate sizes and shapes of continents. Flat maps (physical or political) always distort either size, shape, or both due to the challenge of projecting a sphere onto a flat surface. Posters are not to scale.

It's the correct choice. Icons are the geographical objects used to represent commonly used application.

 In this, all the computers are connected to one another to form ring i.e. last node gets connected to first node. It covers the large geographical location because implementation of ring topology is easy. The addition and removal of computersin already existing network is difficult.  

Soil profiles shows different layers of soil, and each layer is known as soil horizon.
