I applied via Company Website and was interviewed in Dec 2020. There were 3 interview rounds.
Resolution refers to the level of detail in a GIS dataset. It can be spatial, temporal, spectral, or radiometric.
Spatial resolution refers to the size of the smallest feature that can be detected in an image or dataset.
Temporal resolution refers to the frequency at which data is collected over time.
Spectral resolution refers to the number and width of the bands in a multispectral image.
Radiometric resolution refers to ...
Spectral resolution refers to the ability to distinguish between different wavelengths of electromagnetic radiation, while spatial resolution refers to the ability to distinguish between different locations on the ground.
Spectral resolution is measured in terms of the number of bands in an image and the width of each band.
Spatial resolution is measured in terms of the size of each pixel in an image.
Higher spectral reso...
Satellite images are captured from space while toposheets are 2D maps of the earth's surface.
Satellite images are captured from space using satellites and provide a bird's eye view of the earth's surface.
Toposheets are 2D maps of the earth's surface that show the terrain, elevation, and other features.
Satellite images are more detailed and can capture changes over time, while toposheets are static and provide a general...
GIS components include data, software, hardware, and people. Topological errors can be resolved using tools like topology rules and editing.
GIS components include data, software, hardware, and people.
Topological errors can be resolved using topology rules and editing.
Topology rules ensure that features are connected and do not overlap.
Editing tools like snapping and tracing can help fix topological errors.

I applied via Approached by Company and was interviewed in Nov 2021. There were 2 interview rounds.
OLT stands for Optical Line Terminal, a device in a passive optical network that serves as the endpoint of a network.
OLT is responsible for converting electrical signals into optical signals for transmission over fiber optic cables.
It connects the PON (Passive Optical Network) to the service provider's network.
OLT manages the traffic between the ONU (Optical Network Unit) and the service provider's network.
Examples of ...
Radio frequency refers to the range of electromagnetic frequencies above audio frequencies and below infrared light.
Radio frequency is used for communication and broadcasting purposes.
It is commonly used in technologies such as Wi-Fi, Bluetooth, and cell phones.
RF signals can be transmitted wirelessly through antennas.
RF waves have different frequencies and wavelengths, allowing for various applications.
Examples of RF ...
GIS stands for Geographic Information System, a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data.
GIS is used to visualize, interpret, and analyze data related to locations on Earth's surface.
It integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.
Examples of GIS applications inc...
GIS is used to analyze, visualize, and interpret spatial data for various applications.
GIS is used in urban planning to analyze population distribution and land use
It is used in natural resource management to monitor forests and wildlife habitats
GIS is used in emergency response to map out disaster areas and plan rescue operations
GIS has advantages like spatial analysis and data visualization, but also disadvantages like cost and complexity.
Advantages: spatial analysis, data visualization, decision-making support
Disadvantages: cost, complexity, data accuracy issues
Examples: GIS can be used to analyze crime patterns in a city, but may require expensive software and training
