The meteorological satellite data serve as main information source, assisted as auxiliary information sources by the landsat satellite TM data, land use thematic maps and meteorological observed data. A correlated pattern on the ground surface brightness temperatures and air temperatures has been studied and established with good performance of application.展开更多

To pursue this goal, a PPGIS （public participation geographic information system） was developed, allowing the interaction, discussion and public participation of the stakeholders and actors involved. This PPGIS emerged as a crowdsourcing tool, with the purpose of assisting the georeferenced contributes from the local users of the Marine Park, regarding several relevant subjects, such as pollution, economic activities, opportunities and threats to the Marine Park, providing visual, analytical, and demonstrative qualities.展开更多

This study was carried out in order to map soil chemical properties and macronutrients status in North, Center and South districts zones of Gujarat state. Geographic Information System (GIS) was used in this study to present the secondary data of the soil which were obtained from Anand Agriculture University (AAU), Gujarat. The major objective of this study was to analyze & visualize the secondary data of soil through IDW, spatial interpolation techniques for suitable mapping in a selected North, Central and South districts of Gujarat state. Various maps showing spatial distribution of micronutrients and chemical properties for North, Center and South districts zones of Gujarat state were prepared. These digital maps can be used in precision farming studies with the application of fertilizers and micro-nutrients as per the requirement and the recommendations. This approach is proposed as a method for the evaluation of sustainable soil management practices such as variable rate of fertilization. This study demonstrates the usefulness of geo-informatics technology in soil survey as well as applications of various micronutrients to specific areas based on recommendations.展开更多
