The New York State GIS Program Office (NYSGPO) is pleased to announce that we now have a web service available for hydrography data in New York State.   This hydrography dataset is a subset of the National Hydrography Dataset (NHD) that loads filtered subsets of the NHD Waterbody, NHD Area, and NHD Flowline.  We offer two map services (one solid fill, one hollow fill) that the end user can choose from, both services hit the same underlying data.   These services are also scale trigger for waterbody size and labeling, more information about what is filtered out and what is scaled triggered is available in the service description of each service.
