Description:
Abstract: This shapefile contains polygons representing the historical land cover within the watersheds near Fair Haven, New York, on the southeastern shore of Lake Ontario. These land cover boundaries and types were interpreted from aerial photos dating from 1973.
Purpose: To evaluate broad changes in land cover over time.
Supplemental_Information: This dataset was developed as part of the Lake Ontario Biocomplexity Project. For more information, see: <http://ontario.cfe.cornell.edu/>

Data_Quality_Information

Logical_Consistency_Report: Unknown
Completeness_Report: It should be noted that the cover class 14, "farms and land in farm buildings", is very dependent on the scale of the photos for each given year. For general analysis this category could be grouped with the agricultural cover classes if wished. The wetland classes (numbers 10, 11, and 12) were interpreted by Nicole Hotaling of SUNY ESF for the areas adjacent to the embayments. The wetland cover class 10, woody wetlands, was interpreted by the general group for areas within the larger watersheds.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: It is important to note that the aerial photos used for this project differed in resolution, scale, and distortion. Therefore the level of detail within each of the landcover maps varies. Additionally, due to this distortion the resulting maps do not align perfectly at boundaries such as shorelines and embayments and even fixed objects. The project group took as much care as possible to get good registration, and achieved the best possible without advanced triangulation and other interpretation techniques that were beyond the scope of this project. Users of these maps should be aware of these limitations and use them as general depictions of the land use and land cover and use them to only evaluate broad changes over time.
Lineage:
Process_Step:
Process_Description: Files were created by aligning historical aerial photographs along flight lines and tracing landcover classes onto clear acetate overlays. The polygons on the overlays were then digitized into ArcView GIS in Sibley Hall at Cornell during the Summer of 2003 by our REU intern, Seth Lozano. Interpretation of the aerial photos was done by Seth, Andrea Parmenter, and the rest of the summer field interns. All photos for the project were provided by the Cayuga County Planning Department in Auburn, NY. Registration of the acetate overlays to real world coordinates was accomplished by using a series of tic marks (e.g. road intersections for which we knew the coordinates and could locate on the photos). In all cases care was taken to minimize the root mean square (RMS) error, and hence distortion caused by registration. The RMS values and tic IDs used for each map can be found in the red airphoto documentation notebook in 306 Rice Hall.

Process_Description: CUGIR staff defined the dataset projection as UTM18N (meters, NAD27), removed extraneous attributes, and exported the data as a shapefile.
