Remote Sensing, QGIS and Data Import

Learn about remote sensing, quantum geographic information systems, and data importation in this free online course.

Publisher: NPTEL
This free online course will help you become competent in remote sensing and georeferencing an image in the geographic information system. You will gain a grasp of spatial analysis, the limitations of having a geographical information system in place, and the problems encountered in establishing GIS. This will then help you to gain an understanding of the procedures involved in integrated data analysis, spatial interpolations, and extrapolation.

This course will begin by introducing you to remote sensing in GIS, spatial analysis, basic spatial analysis with examples, and also advanced spatial analysis. You will learn about the limitations of having a geographical information system in place, and the problems encountered in establishing a GIS. You will also learn about report generation from attribute data, complex operations on attribute data, and the overall procedure for a polygon overlay. 

Next, you will study the points on a polygon, buffer zones, and the procedures in integrated data analysis. This will lead you to network operations, proximity operations; spatial interpolations, and extrapolation. You will then become familiar with bilinear interpolations, GIS analysis models, cartographic algebra, and digital terrain models. This will further introduce you to the interface of QGIS, importing vector data, tabular data, and raster data into the QGIS interface. 

Lastly, you will gain an understanding of the properties, identification of features; the attribute table followed by metadata inspection and properties viewing in QGIS. You will then further your knowledge on the process of downloading a topography map from the survey of the Indian portal, exploring the georeference tool and window. You will also familiarize yourself with the georeferenced plugin, georeferencing an image, and transformation settings. This will then bring you up to speed with how to dissolve various polygons into one single polygon, and joining tables. You will also master how to merge two different industry layers and then extraction of the road layers.
