Hyrax - Bad Request (400)


Bad DAP Request

It appears that you have submitted a Bad Request.

The specific error message associated with your request was:

Caught a C++ standard exception in responseBuilder.intern_dap2_data. The error was: 
You asked for too much! 
    Maximum allowed response size: 4294967296 bytes.
    Maximum allowed variable size: 2147483648 bytes.
The submitted DAP2 request will generate a 5793995404 byte
response, which is larger than the maximum allowed response size.

In addition to the overall response being too large for the
service to produce, the request references the following
variable(s) that are each too large for the service
to process.

Oversized Variable(s): 
    Float64 swan_DIR[1727][417641] (5773483008 bytes)

You can resolve these issues by requesting less.
 - Consider asking for fewer variables (do you need them all?)
 - If individual variables are too large you can also subset
   them using an index based array subset expression 
   to request a smaller area or to decimate the variable.
You can find detailed information about DAP2 variable sub-setting
expressions in section 4.4 of the DAP2 User Guide located here:
https://www.opendap.org/documentation/UserGuideComprehensive.pdf 

There may simply be problem with the syntax of your OPeNDAP URL. If you are using server side functions in your constraint expression you should double check the syntax of the functions that you are attempting to use.

It may also be that the URL extension did not match any that are known by this server.

Here is a list of the six URL extensions that are be recognized by all DAP servers:

dds - The DAP2 syntactic (structural) metadata response.
dds - The DAP2 semantic metadata response.
dods - The DAP2 data response.
info - The DAP2 HTML dataset information page.
html - The DAP2 HTML data request form.
ascii - The DAP2 ASCII data response.

In addition Hyrax and other new servers support the following DAP4 URL extensions:

dmr - The DAP4 dataset metadata response.
dap - The DAP4 data response.
dsr - The DAP4 dataset services response.
ddx - The DAP3.2 dataset metadata response.

If you think that the server is broken (that the URL you submitted should have worked), then please contact the OPeNDAP user support coordinator at: support@opendap.org
