Monitoring data via multiple sources or a central solution?
For many or even most larger-scale operations, permits require many different media to be monitored (e.g. air, soil, surface or groundwater, and noise). Often this needs to be combined with supplementary data (e.g. production or weather) and meta-information (e.g. flows, height, location).
Different frequencies apply to different data streams, different compliance levels, calculations, and so on.
Often monitoring equipment comes with its own software but this rarely seeks to combine its data with data from all of the other equipment on the plant, field readings, and lab reports, etc. – nor manage many of the other permit requirement such as managing monitoring schedules, analysis of collated data sets or reporting. These information silos of data are often different from one another with varying interfaces and capabilities.
Data integration involves combining data residing in different sources and providing users with a unified view. An integrated system solves many of the problems inherent with information silos. They can;
- Mantener y gestionar todas las partes clave del permiso relativas a la vigilancia.
- Maneje todo el plan de monitoreo.
- Harvest, validate, and alert issues.
- Combine, Collate, aggregate, and calculate different data sets.
- Proporcionar una plataforma única y uniforme para analizar y comunicar todos los datos de vigilancia.
- Permite compartir información a través de una organización de forma controlada y segura.
- Evitar muchos casos de error humano mediante el copiado y el pegado de un sistema a otro y en, por ejemplo, hojas de cálculo.
How should environmental monitoring data be organised?
With so many different datasets – how is it possible to combine them into one single interface? This needs a lot of skill and experience to do, however, with the right tools, it can be done with virtually any type of monitoring data.
La automatización también es vital. Lo ideal sería que un sistema minimizara al máximo la necesidad de que los usuarios lo poblaran continuamente con datos y arreglaran los problemas de importación.
How is your data collected and housed today? In most cases, any organisation will have numerous different loggers or sensors, laboratory results, and production data. How is all this data managed today, most likely in spreadsheets or proprietary databases. In order to manage environmental data properly, there is a need to collate all these different sources into one, manageable location.
Files coming from multiple different silos will inevitably have almost as many different layouts as there are data sources, and it is usually simply not practical or possible to seek any consistency between them. Things like header information, column names, column order, file orientation – is every column a different parameter in a cross-tabulated layout, or maybe sample point headers, of the file could be a long list. So your importer needs to be intelligent and flexible. It must be able to read most files with no user input, to interpret column order and orientation, and so forth. Sometimes this will not be sufficient, so user configuration for special cases should be provided, along with the ability to insert custom scripts or macros to deal with the trickiest of layouts.
Many data streams have special cases or rules which need applying. Some equipment might provide US dates. It is imperative that the importer knows this and how to handle it. Is 07/08/2018 August or July?
Hay muchos formatos de fecha que varían - 01/02/2018 2018-01-02 01-Feb-2018 y así sucesivamente.
Muchos archivos .csv tienen separadores de columna de comas, pero se pueden encontrar otros delineadores como punto y coma o tabulador. El importador necesita saber qué esperar.
A otros archivos les pueden faltar columnas. Por ejemplo, un medidor de flujo sabe de qué medidor se trata y puede no incluir su nombre en el archivo de salida. Esto tendría que ser especificado al importador, o "todos los archivos que llegan a la carpeta is son de x laboratorio", etc.
With laboratory readings, < symbols are common (e.g. <0.01). They simply mean ‘below detection limit’. This doesn’t mean zero, but different regulators have different requirements for their handling. Is it the full amount up to the detection limit, half of it or zero? Your importer needs to know which in order that it can interpret not just as text, and post the correct number in the database for use in interpretation, but also as a text for reports.
Los separadores de decimales de coma (por ejemplo, 0,01) son comunes especialmente en Europa continental o en los países de América Latina. El importador debe entender que no es un separador de columna sino un "punto" decimal.
Así que en la configuración, el usuario o el administrador debe tener opciones y flexibilidad sobre cómo configurar cualquier flujo de datos.
Naming can be a huge problem if not handled correctly. Different equipment might call the same location something different, e.g. ‘channel 1’ might identify the same location as ‘stack 1’, or overtime people manually recording a name differently, e.g. BH1 BH01, Borehole 1. These must all be combined, and the imported has to know the variants. A good importer will learn these aliases over time and hold the mappings in order that it only needs to ask once.
Can your system handle multiple file formats, for example, CSV files, Excel spreadsheets, text files?
Automatic aggregation and calculation are often not as simple as it might seem. Take one seemingly simple example of a mg/m3 compliance limit. There might be a sensor measuring mg/l and a flow meter measuring m3/minute, both at different intervals. The calculator must know where to search back in time to find the nearest applicable reading to use. Or rules on how to handle a meter going round and back to zero. Once the result is obtained, there may now be a new data set that now needs a compliance check (and alert if appropriate). There are many complications that need handling.
To conclude, there are many reasons for integrating environmental systems and have listed the most common difficulties. Let the experts help you achieve a smooth and streamlined implementation and drive your business forward with easy to use environmental intelligence.
