Notes
The 2 forms on top of this page are live.
Fill in either form and then click "Calc".
Underneath will be displayed the string that was sent to the server and the status code and results that were received from the server.
"Success" will be set to "true" if the conversion was successful or "false" if it was not.
If "success==false" an additional field called "errormessage" will be set as follows:
{
"success" : false,
"errormessage" : "inputdls(): Range '233' is invalid"
}
Below the status lines, the parsed results and raw geojson string are displayed.
