NYS Department of Environmental Conservation Current Update Approximately ½ the state has been updated to NYS digital orthoimagery (NYDO) for features appearing in the state’s current “framework hydrography” The state’s framework hydrography is generally much less dense than the NHD so this is not a complete update Agreement with NYS GIS Clearinghouse to replace framework hydrography with NHD when update is completed This work is being completed via a combination of the NYS-DEC / University at Albany partnership, a NYS- DEC / USGS workshare, and contractor support

Challenges Resistance to adoption of event model in many programs due to the difficulty of event creation / editing (need to ‘franchise’ event maintenance) Need to increase partner education & training Need to transfer planning level events in NHD Plus to management database in High Res

NYS Department of Environmental Conservation Short Term Goals Finish the current update and replace the State’s Framework Hydrography with the NHD (1-2 years) Implement the HEM tools in NYS-DEC programs currently using events Implement NHD/WBD Stewardship coordination 2,500 square mile update by NYC sub- steward from ortho/lidar source, start ‘09

NYS Department of Environmental Conservation Long term plans Continue as NHD Steward Develop process / plan to accept updates from other entities including sub-stewards Develop ways to integrate updated elevation data (LiDAR) into NHD update process
