Sending Data to Atlas

How are sensor readings transferred from the site to Atlas?

Logger-to-PC-to-AtlasLogger to PC to Web

A PC retrieves data from the logger and then forwards the data to Atlas via the internet. This is the most common way to send data to Atlas, and it can be fully automated.

The PC connects to the logger (see summary of options) and runs software to communicate with the logger. The software is supplied by the logger manufacturer. The PC, which must be connected to the internet, then runs software to forwards the data to Atlas. FTP Scheduler, supplied free to Atlas users, is an example of software that runs automatically.

Logger to WebLogger direct to Web

This method eliminates the PC. Instead, the logger is programmed to operate a cellular modem and to transmit data at regular intervals to the internet via FTP or SMS. This method will become more common as the cellular networks increase their coverage and bandwidth.

Browser to WebBrowser to Web

Atlas also accepts manually acquired data, such as water levels measured with a water level indicator. Users can enter these readings with their web browser. Sometimes data are best processed with specialized software or a spreadsheet. Users can upload the resulting plots to Atlas. These can be displayed on screen and included in reports. Finally, users can make entries in the project logbook and upload photographs.

Questions about sending data

Does Atlas retrieve data from data loggers?

No. Data must be sent to Atlas. This task is normally performed by a PC. The PC retrieves data from the logger and then fowards the data to Atlas.

What data formats does Atlas support?

Atlas currently supports the Atlas format, Campbell Scientific formats (array-based and table-based), and a Geodetic format. The VW MiniLogger is also supported, since it can output data in the Campbell format.

Custom input filters for other formats can be programmed on request.

Can users enter data manually?

Yes. Atlas provides a convenient way for users to enter data using their web browsers. This is useful for values that are not normally logged, such as fill height or standpipe water levels.

Atlas also provides a logbook so that users can enter project-related observations and photographs. Again, only a web browser is required.

Is internet service provided with Atlas?

No. The connection to the internet must be obtained from local internet service providers. Dial-up access to the internet is economical if there is already a telephone line to the site office. Cellular connections may also be an economical alternative in some locations.
