Geospatial Technology is one of the widely accepted, detailed and useful ways to develop land use classification of maps. This review expects to research the effect of the spatio-temporal elements of land use land cover (LULC) patterns in Vontimitta Mandal, YSR Kadapa district, Andhra Pradesh using Geospatial technologies. LANDSAT-8 OLI data for the years 2014 & 2020 used as main input data for this study particularly after bifurcation of the state. A semi-regulated cross breed arrangement strategy was utilized for picture order and post-grouping procedures for LULC change discovery. The greatest probability characterization calculation is utilized to recognize LULC changes in the review region. The review region is arranged into five significant LULC classes' in particular Horticultural land, Timberland land, Developed region, Water bodies and Waste grounds. Exactness appraisal of LULC was assessed utilizing a disarray matrix in Arc GIS software and ground truth corroboration. Based on LULC maps, major changes identified in the study area from 2014 to 2020 are mentioned hereunder. Agricultural land is decreased by 11.41%, Forest land is decreased by 1.72%, Waste land is increased by 1.60% Built up land is increased by 15.49% and Water bodies decreased by 0.77%.

The daily rainfall data for twenty eight years is used to understand normal precipitation, deficit precipitation. Rainfall records of the Yerraguntla mandal were collected for a period of 28 years (1990 to 2018). The minimum annual rainfall (422 mm) has been recorded during 2002-2003, whereas the maximum rainfall (1155mm), has been noted during 1996-97. Analysis of rainfall data helps in exploring problems related to rainfall that may be high intensity, low intensity, erratic or no rainfall. At the same time analysis of historical rainfall data in semi arid region helps in understanding issues related to drought. These estimates may act as possible pathways to and helps policymakers in understanding erratic rainfall distribution across semi arid region which is important for future planning and management strategies.

Demand for groundwater is increasing due to paucity of surface water and recurrent failures of monsoons. Increasing demand for groundwater causes water level to decline and water quality to deteriorate. This data article is aimed to investigate the quality of drinking water of Obulavaripalli Mandal YSR district based on water quality Index (WQI). To evaluate WQI in the study area, twenty groundwater samples were collected and different physico-chemical parameters viz., pH, EC, TDS, TH, total alkalinity (TA), calcium (Ca 2þ), magnesium (Mg 2þ), chloride (Cl À), sulphate (SO 4 2À) and fluoride (F ˉ) were analyzed. WQI data for groundwater samples indicated that 30% of the samples fall under excellent rating, 40% of the samples fall under good category and another 30% of the groundwater is under poor category. Overall groundwater quality is not suitable for drinking purpose.

/ Buffer Zone. In the present study, Physico-Chemical characteristics in the Buffer Zone of 1.5Km along the Oppidan
course of Buggavanka environs at kadapa are studied. Geographically it lies between the latitudes of 14.23°N & 14.31°N
and the longitudes of 78.46°E & 78.54°E and covered in the open series maps of Survey of India (SOI) Toposheet
numbering D44G15NW. The average elevation of the urban parts of Kadapa is 138 metres. The environmental parameters
evaluated include pH, Total Dissolved Solids, Electrical Conductivity, Carbonates, BiCarbonates, Calcium, Chloride,
Potassium and Sodium. The estimations of the above parameters reveal a considerable deviation from the standards
prescribed by World Health Organisation (WHO). A brief attempt has been made to study the extent of change in the
quality of water in comparison to water quality standards of World Health Organisation (WHO).
Geospatial Technologies provide an ambient and quick renaissance of the analysis and spatial distribution studies
on the results obtained. From the distribution and correlation studies in the study area, it can be concluded that the water
parameters taken are beyond the imagination for consumption either for irrigation or domestic purposes. The pollution
levels for both surface water and bore wells/underground are discussed at length including their spatial distribution and
correlations studies. The results of the present study throw light on the level of pollution stretching its tentacles on the
inhabitants all along the study area.

The groundwater quality is a function of natural processes as well as anthropogenic activities. The safe potable water is enormously essential for living and groundwater is one of the sources for human consumption in both urban as well as rural areas. The area is located in the survey of India toposheet Number 57 J/3 lying between east 78 0 00 ' 0 '' to 78 0 15 ' 0 " longitudes and 14 0 15 ' 0 '' to 14 0 30 ' 0 '' North latitudes covering an area of 720 sq. kms. Geologically, it is underlain mainly by Peninsular gneisses of Archean age followed by Gulcheru and Vemapalli formations comprising quartzites, conglomerates, dolomites and shales. Major geomorphic units are denudational hills, residual hills, pediments, pediplains, structural hills and valleys. The study area experiences a semiarid climate. Physicochemical parameters viz., pH, total hardness, calcium, chloride, total dissolved solids, fluoride were analyzed. Most of parameter show higher value than permissible limit in pre and post monsoon. Further, a moderation in water quality was observed after the monsoon season, which can be attributed to a possible dilution due to groundwater recharge People dependent on this water may prone to health hazard. Therefore some effective measures are urgently required to enhance the quality of water in these areas.

Sand deposition in river is the biggest source of sand, in recent times there has been immense pressure on Rivers which acts as a treasure for the building sector due to rapid growth in the development activities. The main objective of the study is to investigate, recognize the sand mining areas of Papagni and Pennar River in parts Kamalapuram, Kahjipeta, Vallur, Chennur and Kadapa Revenue Mandals of YSR District, Andhra Pradesh, by using Google earth temporal data for environmental monitoring and sustainable development. A total of 9 major sites were identified demarcated from Google earth and the areal extent calculated using arcGIS10 software. The largest part of the sand mining was identified at locations of Kamalapuram and Vallur Mandals, might be due to well connecting roads nearer to the sites when compared to the other sites whereas locations of Khajipet and Kadapa mandals were least affected might be due to Geographic setting(hiily region). This study is an attempt to know the utility of Google earth, Remote Sensing and GIS software tools in the field of natural resource monitoring and environmental protection.
