FlatGeobuf is built for large datasets and cloud-native web maps. ODS is built for open-source office suites and the public sector.
FlatGeobuf
FlatGeobuf is an open, binary vector format built on FlatBuffers. It stores features with a built-in spatial index, so software can read just the area it needs.
It is one of the fastest formats to read and write, and it can be streamed over HTTP from cloud storage without a map server.
ODS
ODS (OpenDocument Spreadsheet) is the open, ISO-standard spreadsheet format used by LibreOffice Calc and also supported by Excel and Google Sheets.
Location is stored in coordinate columns or as WKT text. Public bodies often prefer ODS because it is an open standard.
Your FlatGeobuf file
A FlatGeobuf file holds one layer.
