• Provide all County Departments centralized access to critical base map information such as streets , tax parcels , aerial photography, and address points • Increased cost sharing between departments and maximized data sharing capabilities • Have access to current layers maintained by other departments throughout the county Property Appraiser staff indicated that access to the following layers would be beneficial : • Utilities Parks • Building permits • Site plans as they are submitted (instead of waiting for emails ) • Land use and zoning (instead of importing shapefiles) Address information ( county-wide address point layer) In addition , providing access to a centralized enterprise geodatabase will allow street centerlines to be shared in a more efficient manner. At present, Emergency Services updates and maintains the streets while many other departments use copies of the data set for their particular purposes . This inefficient method prohibits much of the necessary data sharing that is possible through a centralized GIS server. For example , the Property Appraiser currently uses a copy of the street centerline layer and adjusts it spatially to fit with the parcel base for map labeling and display purposes ; two problems result from this process , first, consumption of time to manually move streets, and second , continually working with outdated street centerlines as new streets are added regularly. Base Maopina The Property Appraiser ' s Office is tasked with the maintenance of the parcel layer, and over time has developed an adequate tax parcel dataset, although spatial accuracy seems to be an issue . As aforementioned , the parcel boundary layer is a critical GIS base map layer from which additional layers are derived and referenced across multiple departments within the County . As a result, the Property Appraiser ' s Office plays an important role in maintaining one of the key datasets for the County ' s GIS initiative . At present, the GIS Mapping Coordinator and GIS Mapper' s in the Office maintain and update the parcel layer in an ArcGIS SDE geodatabase . ArcGIS is being used to make edits to the parcel feature class as new plats and subdivisions are submitted . New parcel numbers are assigned to the data set as new features are created . At present, attribute information within the parcel layer, to include parcel number, tax code, use code , owner name, site address , and sales code among others , is very accurate and up-to-date . However, as previously noted , the spatial accuracy of the layer is an issue that needs to be addressed . The GIS Mapping Coordinator indicated that a base map enhancement project is currently being pursued by the County Surveyor. The Property Appraiser' s Office should work in close coordination with the recommended GIS Director to ensure that the parcel layer' s spatial accuracy is improved over time as a result of the enhancement project . This effort will provide the County with a very accurate base parcel map over which all other GIS data sets can be overlain . Another key consideration to be made in regards to the parcel layer is the planned conversion to a new CAMA system . Staff indicated that no modifications to the existing geodatabase will occur until this transition is complete . As aforementioned , the transition 164 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment
