About:
libdap is a C++ library that implements the OPeNDAP (Open-source Project for a Network Data Access Protocol) client and server specification. It enables scientific data providers to create data services that allow clients to access and manipulate large, diverse datasets over the internet efficiently. Its primary value is in facilitating remote data access and subsetting, eliminating the need to download entire large files.

Key Features:

Implements the OPeNDAP protocol (DAP2/DAP4) for data access
Supports data subsetting, aggregation, and type negotiation
Provides a C++ API for building both clients and servers
Enables access to diverse scientific data formats through a common interface

Use Cases:

Building data servers for climate and earth science datasets
Creating client applications that query remote scientific data repositories
Enabling web-based visualization tools to access large data files without full downloads

Alternatives:

netCDF – netCDF is a data model and file format; libdap is a protocol library that can serve netCDF files remotely but also handles other formats.
THREDDS – THREDDS is a server suite that often uses libdap or similar protocols to serve data, while libdap is the core protocol library itself.
