Geo-Spatial Technology for Urban Sprawl Monitoring

Posted by

How GIS and remote sensing can be used to monitor urban growth or land use changes

Urban sprawl detection at zones level of Jaipur city for better monitoring and planning (2008-2013)


Urban Growth estimation and monitoring is important process for urban planning for future development. The current growth and past trends can help to predict future demand for urban planning. 

The urban growth can be assessed using data created through satellite images. Satellite data cover important aspect that is temporal information, one can map urban growth of current as well past. 

GIS is a versatile tool, in which mathematical and statistical concepts can be integrated very easily. Therefore, GIS tool can be used for simulation and prediction of urban patterns for future. 

To assess the urban sprawl, built-up area is quantified using temporal satellite data for 2008, 2011 and 2013. Built-up area, which refers to the residential and commercial areas, industrial complexes, roads and paved ways etc., is captured for the Jaipur city using satellite data and Image processing software. 

The standard image processing techniques, such as image extraction, rectification and classification have been used for the analysis of three satellite images. Supervised classification using maximum likelihood classification (MLC) algorithm has been performed for the classification of satellite images. 

The algorithm was trained by supervised training process, after collection of parametric and non-parametric signatures. 

The classification results obtained from supervised classification are re-checked with ground data and other secondary data to find out wrongly classified or missing pixel and these pixels were updated adequately.

Functions of GIS GIS comprises many functions and these functions can be used in variety of applications. The GIS functions facilitate some basic reply those are below. The GIS process provides location based information, which helps to locate the particular location of objects. The location can be defined by longitude and latitude or X/Y and this also can have attribute information such as place name etc. The GIS functions also support to find the locations under certain conditions such as industries within 5 km from the sewerage treat plant. These functions also help to assess the changes on specific location over the time. It also supports to analyze the spatial relationship among objects with their geographic locations. The functions also provide model based queries, such as optimum path, suitable land for industry development etc. Data Collection and Capture Remote sensing images , existing maps, tabular data, ground survey, internet etc. are used to collec

QGIS for  Conversion of degree decimal co-ordinates to UTM co-ordinates This article will share the conversion process of coordinates such as degree decimal to UTM coordinates. Usually, while collecting the data using GPS from the field, the coordinates are in degree decimal format.   For conversion of degree decimal co-ordinates to UTM coordinates, one need to use converter from different website and excel tool. But these tools are also available in GIS software. So in this article process of converting coordinates from degree decimal to UTM in QGIS is shared with screen shots. In the beginning, one has to copy the degree decimal coordinates into Excel file as shown below. The data should have following descriptions such as point ID, Latitude and Longitude. Now save this excel file as Comma Delimited format (.CSV format). Now Open QGIS by clicking on Start then go to All Programs  and then click  QGIS Desktop 3.8.3 . Following window will open Open the .CSV file vi

There are several methods through which height/elevation can be measured using satellite image and aerial photographs . In case of satellite image such as, Cartosat,  ASTER, Worldview I & II and others are used to create height or elevation data in the form of digital elevation model .  Aerial photography, LiDAR mapping are very common for creation of elevation data on higher scale/resolution for detailed study.  In the last article, relief displacement used to measure height of any object on earth surface. Here in this another method will be discussed to measure height of any given object on the earth surface. Parallax for Height Measurement using Aerial Photography Parallax Concept Photogrammetry is capable of measuring elevation of earth surface. Aerial photographs/stereo pair satellite images can be used to measure elevation differences through the use of parallax method.   New launched satellite are providing stereo pair satellite images images such worldview-2 etc.
