Comma Separated Value (CSV) Data Format

We are looking to store the following information for each data point in our data file

Please note that E1 and A1 relate to S1, E2 and R2 relate to S2 and so on. The order is significant.

The following example shows the readings from a single tile (n lines, one for each sensor) in the data file. It represents the readings from a tile at position (7, -10) in Dennis 128. In the CSV format, strings are enclosed in quotation marks only if they contain special characters (commas, newlines etc.). Spaces are omitted unless they are part of the data, blank entries are represented as "" and quotation marks within the data are escaped by placing a second quotation mark beside it.

Collecting Data

The data synthesis group decided that it would be more efficient to have bots create their own data file rather than editing and updating an existing full template of the room. This allows for smaller data files with a high percentage of data / structure.

Analyzing Data

Data files (multiple per room) will be placed in a central location where we all have read write access. These files can then be compiled on the fly and displayed graphically. It is currently planned to do this through a PHP web page enabling each group seeing a dynamic view of room map and facilitating their further mapping efforts.

Initial brainstorming has led to the identification of the following tile states in the map:
