h3. Survey data

Raw survey data are contained in CSV files, typically downloaded from surveying instruments.

See more information of the process for the survey data (including a flow diagram): [[Survey data]]

h3. Categories

The categories define the types of the geographical features.

See [[Categories]]

h2. Hosting

The team is located in the CSR of Auroville.

We have setup a server for hosting the software and database. See [[CSR_server]] for technical information about the setup.

h3. Backup and restoration of the database
