System access and data overview
OBIS can be found under http://www.future-okavango.org/obis. Opening it in your favourite web browser you are greeted with the following screen:
Two menus (marked in red) offer access to various generic functions (top menu) and data types (left menu). Via the top menu, the following OBIS functions can be accessed:
- Search: allows to globally search over all data types
- Reporting: shows lists of recently changed datasets
- Account: allows to change user specific information (e.g. password or language)
- Admin: global admministration functions (e.g. user / permission management, system log files)
- Login/-out
The left menu provides access to OBIS data about:
- Persons and organisations: persons and organizations referred to in metadata of various other data types
- Study sites: descriptions of locations (i.e. points or areas) that (field) research is being done at
- Observations: general field observations done at study sites, used for information not being covered by other data types
- Vegetation: vegetation observations, can be linked to study sites
- Soil: soil observations, can be linked to study sites
- Rivers: rivers and their tributaries
- Stations: measurement stations, their location and type (e.g. climate station, streamflow gauge, ...)
- Time series data: time series of measured and simulated data, together with information about their stored parameters, source and data gaps
- Geodata: geospatial data in general with description of their projection, type and other metadata
- Scenarios: general purpose future development scenarios (e.g. related to climate or land use change)
- Indicators: environmental indicators and their values suited to evaluate scenarios applied to study sites
- Documents
- Glossary
User account
As a default, users are logged in automatically as a guest user. In OBIS, the guest user account already allows to access a variety of functions, including
- searching for / displaying meta-information of most stored data
- visualizing interactive maps and previews of geospatial data
- displaying previews of time series graphs and images
The guest user is not allowed to access and download detailed information such as time series or geodata. The same holds for accessing restricted and account specific functions like language settings (the guest user uses English language). For an individual dataset, specific permissions may have been defined by the dataset owner and such might differ from default settings.
Throughout this tutorial, a user account with typical permission settings will be used. To login with your account, select the Login/-out link from the top menu. Please fill your user credentials into the form as shown in the image below:
If you don't have an account yet, please select the Request new user account link from the same page and provide the required information in the following form as shown here:
Please carefully fill in the information about Affiliation and Request notice as the permissions granted by the OBIS administrator will be based on and justified by these data. Upon submitting the data, an OBIS administrator is notified about your request. Your account will usually be created within one day and your user credentials will be sent to you via an automated email.
Once you have successfully logged in, your currently used user account is displayed below the main menu, e.g. Logged in as: skralisch. In case you are experiencing problems accessing data, please remember to check if the user account shown here is the one you intend to use. To change your user account settings like password, email address or preferred language, select the Account link from the top menu.
Time series data
The section time series data is one of the core features of OBIS. The sectin "Time series data" gives first an overview of all datasets. The measured data are directly linked to the stations (see figure below).
On the screen most important information are listed:
- Dataset title consists of measures parameter and station name, e.g. "Climate Benguela"
- Start of timeseries (yy-mm-dd)
- End of timeseries (yy-mm-dd)
- Time step, e.g. daily, monthly
- TS Measurement + Data Gaps, e.g. precipitation, discharge
- TS Data contains the link to access the data [show]
With a click on "details" you can see all data linked to the dataset. OBIS allows the management,visualization and download of time series data.
