The study of local government continued with this lab which was composed of two scenarios.
Scenario 1 involved students as GIS Technicians employed by the Marion County Property Appraiser's office. The county property appraiser's website and online map were utilized to provide information to a local developer who was interested in the impacts a Fly-In Community would have on property owners adjacent to a specific parcel of land in the county. His request for a preliminary zoning report of the site and adjacent areas was met with a PDF map book and a PDF of contact information for the owners of parcels within 1/4 mile of the subject parcel. The map book was created with data driven pages and included an index map. Each page of the map book focused on one particular area that was overviewed in the index map. Although this project had to do with zoning, creating something reminiscent of DeLorme Atlas and Gazetteers was very gratifying. The fact that the pages are so easily editable is very exciting.
After verifying the certification date of the data, the appraiser's website was navigated to develop a familiarity with it. The Marion County Property Appraiser had very detailed information for the subject parcel. (Something that would have made my own dog quite jealous was discovering the assessed value of $6,500 on the property's doghouse.) This particular website allows the buffering of parcels and downloading of data in .csv format. This data was used to add parcel owners' names to the data already provided using Join in ArcMap. The colors for the different zoning classifications were selected to correspond to the actual colors used in the county property appraiser's zoning map. This would develop a familiarity and provide a reference to the client. Each parcel within a 1/4 mile of the subject parcel was assigned a Map Key identifier. These numbers were also used in the corresponding Parcel Report PDF. Compiling the map book involved using this data and a selection of parcels within 1/4 mile of the subject parcel coupled with the zoning information and streets for reference. The index map for the map book was created to identify which portion of the overall map was the focus of a particular page in the map book. Labeling in data-driven pages is something that I found to be more complicated than labeling layers in a standard map. With more practice that, too, should become second nature.
After completion of the data-driven pages and addition of final touches to the map, the map was exported to a PDF file to be provided to the client. Also provided to the client was a corresponding report of the parcels (identified by Map Key) with parcel ID, owner's name and address, zoning code, and acreage. This report was in PDF form. Generating a report from the attributes will be a handy skill to have. One page of the multi-page map book is included here:

The second scenario of the lab exercise involved providing Gulf County Board of County Commissioners with a PDF list of vacant, county-owned parcels greater than 20 acres which they could consider for the construction of a future Extension office. Completion of this task required merging two parcels and then using editing tools to separate out a portion of the new parcel using a legal description. The new parcel's attribute information was then updated along with the new acreages for each of the two parcels. Selecting by Attributes yielded 75 parcels owned by Gulf County. A Definition Query utilizing Query Builder yielded 11 properties of more than 20 acres. Finally, a Vacant-Improved Code (VICD) Table was joined to the layer, and from this three vacant parcels were located. The results were organized in an attribute report which was exported as a PDF to be provided to the Board of County Commissioners.
