This is where I'll be posting information about istSOS-Data analysis and statistical tools suite GSoC 2017 project to the OSGeo community.

Introduction

istSOS2 Main Page

istSOS is sensor data management tool that allows collection, maintenance and publishing of monitoring observations using the Open Geospatial Consortium (OGC) Sensor Observation Service (SOS)standard.

OAT(Observation Analysis Tools) can be used as a pre-processor for calibration observations, integrating the creation of observations for calibration directly from sensor time-series. The tool consists in an expandable Python library of processing methods and an interface integrated in the QGIS FREEWAT plug-in which includes a large number of modelling capabilities, data management tools and calibration capacity.

OAT library is an expandable Python library that can easily interact with istSOS.

The goal of my project primarily is to create OAT extension in RESTFull Web api and OAT extension having data analysis and statistical tools for istSOS which will be used to automate the creation of statisticate documents using OAT library and harvesting the data from an istSOS server and then publishing the result on Open Data Portals(CKAN).

Idea

The aim of my project primarily is to create OAT extension in RESTFull Web api and OAT extension having data analysis and statistical tools for istSOS which will be used to automate the creation of statisticat documents using OAT library and harvesting the data from an istSOS server and then publishing the result on Open Data Portals(CKAN).
