What is Geography Information Systems (GIS)
GIS is a computer-based information system used to capture, manage, update, analyze, display, and output spatial data and information to be used in a decision making context. It integrates hardware, software, data, people, and allows for the visualization and analysis of data with a geographic component. Some key applications of GIS include emergency response, transportation planning, site selection, and natural resource management.
Digitizing features_2 in ARC GIS
Digitizing in GIS is the process of converting geographic data either from a hardcopy or a scanned image into vector data by tracing the features. During the digitzing process, features from the traced map or image are captured as coordinates in either point, line, or polygon format.
QGIS Tutorial 1
Prepared as part of the IT for Business Intelligence course of MBA @VGSOM, IIT Kharagpur. The tutorial describes how to create an interactive map using the open source software QGIS.
Data Models - GIS I
GIS models reality through abstraction using a mix of raster, vector, and attribute data tailored to specific functions. Topological vector models record shared geometries like points and lines only once, allowing features to be connected and ensuring integrity as changes propagate between related features. Object-oriented models represent real-world phenomena as interconnected objects with their own rules and relationships.

For each tool, it provides a definition, explains how to use the tool in QGIS, and shows an example of the output layer. The document serves as a guide to common geoprocessing tasks and spatial analysis that can be performed in QGIS.
Working with ArcGIS Online
This document summarizes a presentation about working with ArcGIS Online. It discusses ArcGIS Online as an integrated part of ArcGIS that allows users to create and share intelligent web maps on any device. The presentation demonstrates how to use ArcGIS.com to search data, create web maps, and embed maps in websites. It also shows how to use templates to showcase maps in a public gallery. The road ahead section discusses upcoming enhancements to ArcGIS Online, including hosting and portals for organizations to collaborate on maps and data in the cloud.
Geographic information system and remote sensing
ArcMap is where you create maps and access most of the ArcGIS functionality. Remote sensing is an instrument based of observing an object at a far distance without direct contact.
Vectors and Rasters
Vector data stores individual map features with high precision and has a linked attribute table for storing metadata. It is well-suited for mapmaking but poorly suited for storing continuously varying surfaces like elevation. Raster data stores information as a grid of cells, each with a single value, making it ideal for representing continuously varying data but with less precision. Some types of analysis are faster with rasters due to more developed analysis tools, while others are faster with vectors.

- ArcGIS Pro has additional capabilities over ArcMap like improved charting and runs alongside ArcMap as part of the ArcGIS Desktop application.
Remote Sensing: Georeferencing
Raster data is commonly obtained by scanning maps or collecting aerial photographs and satellite images. Scanned map datasets don't normally contain spatial reference information (either embedded in the file or as a separate file). With aerial photography and satellite imagery, sometimes the location information delivered with them is inadequate, and the data does not align properly with other data one has. Thus, to use some raster datasets in conjunction with other spatial data, we need to align or georeference them to a map coordinate system. A map coordinate system is defined using a map projection (a method by which the curved surface of the earth is portrayed on a flat surface). Georeferencing a raster data defines its location using map coordinates and assigns the coordinate system of the data frame. Georeferencing raster data allows it to be viewed, queried, and analyzed with other geographic data.
Generally, we georeference raster data using existing spatial data (target data)—such as georeferenced rasters or a vector feature class—that resides in the desired map coordinate system. The process involves identifying a series of ground control points—known x,y coordinates—that link locations on the raster dataset with locations in the spatially referenced data (target data). Control points are locations that can be accurately identified on the raster dataset and in real-world coordinates. Many different types of features can be used as identifiable locations, such as road or stream intersections, the mouth of a stream, rock outcrops, the end of a jetty of land, the corner of an established field, street corners, or the intersection of two hedgerows. The control points are used to build a polynomial transformation that will shift the raster dataset from its existing location to the spatially correct location. The connection between one control point on the raster dataset (the from point) and the corresponding control point on the aligned target data (the to point) is a link.
Finally, the georeferenced raster file can be exported for further usage.

- The system allows users to upload Excel data, match it to map attributes, generate articles using data science insights, and visualize data on interactive maps.
- Rediff's architecture uses POJOs to define schemas, custom collections to store different data types, and a REST layer to expose data resources and abstract storage from applications.
Data Preprocessing&tools
Data pre-processing is an important step that includes cleaning, normalization, transformation, feature extraction and selection to produce the final training set. It addresses real-world data issues like incompleteness, noise, and inconsistencies. The main tasks are data cleaning, integration, transformation, reduction, and discretization. Data cleaning fills in missing values and identifies/removes outliers. Data is normalized, aggregated, and generalized. Reduction decreases attributes and tuples through binning, clustering, sampling and other techniques. Data mining tools include traditional programs, dashboards to monitor business performance, and text mining tools to extract structured and unstructured data.
