1 Mobile Technology for Real Property Assessment Tax Assessor’s Office Davie County, North Carolina

2 Program Goals  Improve field appraisers accuracy  Manage the field review process for the upcoming 2013 revaluation  Provide data in a mobile environment  Manage building photos– update as needed  Paperless field reviewing/editing environment

3  Print all property cards for a neighborhood  Routing the cards  Print large maps for each neighborhood  Take materials into the field to review parcels, make notes and sketches on the printed property cards  Take photos of houses  Enter data and store new photos in a shared location Old process

4  Edit file created by supervisor  Appraiser imports edit file in tablet PC  Review parcels highlighted on map  Appraiser completes field work (reviews parcels / captures or updates photos)  Appraiser synchronizes photos and field edits  Supervisor reviews field edits and creates report of changes  Changes entered into CAMA system New process

5 Features  Aerial photos and other GIS data (streets, addresses, topography, flood zones, etc…) available in the field  Parcel data available with current ownership and appraisal data (electronically – no paper needed).  GIS tools assist with capturing new buildings and property improvements while the appraiser is in the field.

6  Individual photos are linked to the parcel or building.  GPS enabled for real time navigation.  GIS data linked with data exported from the CAMA system.  Building, land and outbuilding/extra features elements updated in the field. Features

7  Original system linked property cards with the field application. Property cards were annotated in the field and printed in the office. Once printed, the cards were used to update the legacy CAMA system.  Updated system allows user to edit data fields for each record. Features

8  Photo viewer included with the application– no programming required…  Any network user can access building photos Features

9 Application Overview

10 Reval Supervisor Field Data Application

11  Supervisor can control which fields are reviewed

12  CAMA data available for parcel, land, building and obxf

13  Review parcels can be selected by neighborhood, parcel range, etc…

14  Supervisor can manage field review files, see history, print reports, view status, etc…

15  Once field edits are returned, production report will show changes to be entered into CAMA

16 Appraisal Staff Field Edit Application

17  The file menu allows the user to load new edit datasets, manage GIS data, and synchronize edits when completed.  Appraiser selects data to edit

18  The view menu allows the user to change the way parcels are drawn and highlighted on the map view. The user can also run summary reports such as parcel detail and production totals.

19  The GPS menu controls the program’s connection to the GPS device. The user can change the map orientation to the GPS heading to give a more accurate view as they drive along the street.

20  GPS provides navigation and assists with vacant properties.

21  The map view can be rotated to match the user’s current heading. This puts the right side of the map on the right side of the vehicle.

22  Program options control many of the work flow enhancements such as: which fields are displayed when a parcel is selected, when a parcel is marked complete, and whether map tips are displayed for a selected parcel.

23  The menu bar is designed for a step-by-step workflow.  Map navigation is done through the menu bar. The user can also toggle aerial photos on and off. To improve performance, the program loads only the aerial images defined by the current map extent.  A typical workflow includes picking a parcel, taking the house photo, making edits, and marking the parcel as complete.

24  This is a sample of the window control and map legend. Any shapefile format GIS layer can be added to the map view.  Parcels can either be selected from the Map tab, or can be manually typed-in from the Parcels tab.  Once a parcel is located or selected, the image can be viewed in the Images tab.

25  Detail view of the map. Labels on the map can include as much or as little text as needed.

26  Map view showing a selected parcel (using the Pick button). Map tips display basic parcel data.

27  Aerial photo of the same view (available with a simple button click).

28  The Parcels tab shows basic data about the selected record. The user can also search any parcel by typing in the parcel number and clicking Go.

29  Here, an image is found for the selected parcel. The window displays all available images for the selected parcel (if multiple images exist).

30  Original version of the program linked the parcel to the property card.

31  Old process - property card annotation

32  Old process - property card annotation. Appraiser would annotate changes on the card which would have to be printed in the office.

33  New process – Edits made directly to the field data file.


35  In this example, foundation type can be selected from 5 different choices. These options are selected from the appraiser’s edit worksheet.  Any field can be defined with selectable values. Group values can be entered by the supervisor.

36  Structural elements are imported from the CAMA system.

37  Reason codes help with productivity reports and edit tracking. Codes are customizable.

38  The Photo button links the building or parcel to the picture. Images are synchronized from the camera once the appraiser returns to the office.

39  The process is simple and verifies the information as the photo is captured.

40  A location is entered where the photo was taken.

41  Management and organization of building photos. Photo tracking is automated.  More data available to appraisers in the field. Appraisers can also verify address information and accuracy of existing/historical photos. Benefits

42  Increase in productivity.  Workflow tracking (reason codes and productivity reporting).  Historical data and review reports.  PAPERLESS system in the field. Benefits

43  Reasonable cost relative to: Increases in productivityIncreases in productivity Reduction in the amount of supplies used to print and copy maps and other paper documentsReduction in the amount of supplies used to print and copy maps and other paper documents Large number of tools now available to the appraiser in the field.Large number of tools now available to the appraiser in the field.
