These techniques can be used for the purpose of developing urban noise pollution monitoring applications, so they can truly describe the actual urban noise pollution scenario of any region of interest to make effective and informed decisions. In this context, our aim is to use IoT-cloud based framework to generate dynamic (i.e., changes in terms of time and space) noise maps as a service with the help of spatial interpolation techniques. Noise map generation is an effective method for visualizing and assessing urban noise pollution. In this article, we have proposed three spatial interpolation techniques (GLIDW, I-GLIDW, GLIDW-OK) that work on participatory sensing-based noise pollution data collected using smartphones as IoT devices to generate dynamic noise maps. Proposed techniques can address diverse scenarios such as\n            <jats:italic>sparse datasets<\/jats:italic>\n            ,\n            <jats:italic>high accuracy<\/jats:italic>\n            ,\n            <jats:italic>better response time<\/jats:italic>\n            , and so on. Depending on the situation, we can choose an appropriate technique. We evaluate our proposed methods based on a real-world urban noise pollution dataset collected by participants over a period of two years in an urban area of the city Kolkata. The results are compared with inverse distance weighting (IDW) and Ordinary Kriging (OK) methods. The method GLIDW is proposed for a dense dataset. The results validate that in the case of a dense dataset GLIDW dominates over other methods. But, when the data sparsity level is medium, I-GLIDW performs well. However, if the dataset is very sparse, then GLIDW-OK dominates in terms of predictive accuracy. The results also show that Relative Improvement (RI) of I-GLIDW and GLIDW-OK is always positive compared to baseline methods IDW and OK.\n          <\/jats:p>","DOI":"10.1145\/3457609","type":"journal-article","created":{"date-parts":[[2021,6,8]],"date-time":"2021-06-08T16:57:32Z","timestamp":1623171452000},"page":"1-32","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":18,"title":["Spatial Interpolation Techniques on Participatory Sensing Data"],"prefix":"10.1145","volume":"7","author":[{"given":"Asif Iqbal","family":"Middya","sequence":"first","affiliation":[{"name":"Jadavpur University, Jadavpur, Kolkata, West Bengal, India"}]},{"given":"Sarbani","family":"Roy","sequence":"additional","affiliation":[{"name":"Jadavpur University, Jadavpur, Kolkata, West Bengal, India"}]}],"member":"320","published-online":{"date-parts":[[2021,6,8]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph14101139"},{"key":"e_1_2_1_2_1","first-page":"113","article-title":"Research on road traffic noise and human health in India: Review of literature from 1991 to current","volume":"14","author":"\u00a0al Dibyendu Banerjee","year":"2012","unstructured":"Dibyendu Banerjee et \u00a0al . 2012 .
