  • Gridded summary Type 1 (dist_taxa): Sightings of all species are aggregated at 1/0.1/0.01 degree resolution. Users gets the number of species and records per grid cell.
    a: Rectangular grids; b: Hexagonal grids
  • Gridded summary Type 2 (dist_sp): Sightings of each species are aggregated at 1/0.1/0.01 degree resolution. Users gets the number of records of the species in question per grid cell.

Notes

  • The summary of the download requests may not be accurate as the download functionality of the OBIS-SEAMAP mapping tools have been advancing and it is hard to put together old download requests with newer ones.
  • The number of users may be overcounted or undercounted as we didn't collect the information of user identification in early years of OBIS-SEAMAP and the IP addresses are used as a proxy to user identity for old requests.
  • Other issues that may result in inaccuracy is:
    • a user may try downloading data with slightly different criteria for the same project/purpose.
    • a user may download data a couple of times over time to include the latest observations.
    • a user may download data with more coarse criteria and then filter the downloaded data more for specific needs (e.g. download global sightings of a species and then filter them with a study area).
    • a user may download data just for a test purpose.
    • For KML format, a user may visualize the data using Google Earth but did not use them for his/her scientific work.
  • The data type of "diversity indexes" was added in July 2016.
  • Although we have started collecting details of a request (i.e. user's name, prospectus) since Nov 2013, we do not disclose the details unless the user gives us consent. If you want to know more details on the request, please contact us with the Request ID ready. We will try connecting you with the user in question.
