GetCDLImage
General Instruction:
This service takes valid input geotiff files of CDL to convert their format into PNG or KML formats. Multiple files (URLs) can be provided and processed in batch. The files (URLs) can be obtained from the the above "GetCDLFile" services. For example, the request https://nassgeodata.gmu.edu/axis2/services/CDLService/GetCDLFile?year=2018&fips=19015 would return the following.
The URL https://nassgeodata.gmu.edu/webservice/nass_data_cache/byfips/CDL_2018_19015.tif can be used as a file in the requests to be described. Similarly, the request https://nassgeodata.gmu.edu/axis2/services/CDLService/GetCDLFile?year=2018&fips=19015 would return a URL https://nassgeodata.gmu.edu/webservice/nass_data_cache/byfips/CDL_2018_19015.tif . These two URLs will be used in the examples in the section. The assumptions are that these two service requests have been invoked before the examples to be discussed successfully run. Other forms of request, including user-uploaded polygon, would be applicable as long as the returned URL is a valid geotiff file.
