data and digital imagery (Mapping Science Committee, 1994) are considered to be fundamental for GIS usage, especially at the national level. In the above report, the Mapping Science Committee (MSC) has identified five other important data sets: 1.) The digital orthophoto 2.) A street centerline file 3.) A cadastral framework 4.) A natural resource framework 5.) A hydrological framework A recent user survey by the Ohio Geographically Referenced Information Program (OGRIP) confirms these selections at the “local” level (Ohio Geographically Referenced Information Program, 1993). In this survey the following data elements were considered to be of the greatest interest: 1.) Geodetic control 2.) Parcel attributes 3.) Right-of-Ways 4.) Bridges 5.) Parcel boundaries 6.) Street attributes 7.) Street centerline 8.) Municipal boundaries At first glance, the difference between national needs and the local needs appears to be in the natural resource area, however, the OGRIP survey found that the top five data sets that needed to be entered into the respondents databases were: 156 1.) Flood plain 2.) Watersheds 3.) FEMA zones 4.) Land use 5.) Zoning It is important to note that the combination of "most interest" and "most needed" data by the OGRIP survey, corresponds to the more national findings of the mapping science committee. ACCURACY CONSIDERATIONS The OGRIP survey was weak concerning accuracy requirements however according to that survey, almost all "GIS" accuracy requirements were satisfied by s = +2.5 feet. It is pointed out by the MSC that one man’s "accurate" is another "inaccurate" depending on the application. The following table illustrates that fact. In any event and contrary, | might add, to recent emphasis by the National Geodetic Survey, most applications of spatial data leading to decisions relating to land development, environmental problems and even utility line siting, are satisfied by accuracies of s = ¥0.1m. This assertion differentiates between surveying and GIS usage. However, it should be pointed out that in a recent article (Fernandez-Falcon, E., et. al., 1993.) a suggestion is made that spatial accuracy needs for surveying may actually be declining, except for geodynamics, because error propagation resulting from GPS surveys is completely different from that encountered by traditional techniques, and the cost per point has Tab been d therefc data r marke techno Ohio Mappir IN Stand: The ne to effe long | Scienc neede accure Howe focuse: Federe arguab that respon seems this ide profes: importe argume develop for mai arena | facto?) | belie well be
