Yotta MVS integrates the GIS system property parcel base layer, or point layer shape file and digital orthophotographs, to geographically reference structures using the geo-referenced orthophotographs in order to record the position of each structure. The Yotta MVS "Capture" process uses the data associated with each polygon in the shape file to identify and label individual images.

Structure Location

When the operator "clicks" a particular structure on the orthophotograph, the Property Information Collection System (PICS) application retrieves that parcel record from the property assessment file. The operator verifies the address for the structure, then the x-y coordinates and the parcel identification number associated with the polygon in the shape file are permanently associated with the property record about to be collected. In addition to recording the x-y coordinates of the structure, The PICS application records the position of the mobile data collection unit at the time the data of the structure is recorded. A blue dot on the PICS screen shows the GPS position of the Mobile Collection Van as the data is collected for a single-family structure.

Primary Entrance

Yotta MVS’s field crews are trained to collect the x-y coordinate of a structure’s primary entrance. The operator places the x-y point at the location of the primary entrance that falls within the footprint of the structure and inside the roof outline of the structure as shown on the orthophotograph. This process has been developed over a number of years to meet the needs and expectations of Yotta MVS's customers.  Structures, which have been recently constructed, and thus do not appear on the orthophotographs, will have their x-y coordinates estimated from the orthophotographs and the GPS position of the Mobile Collection Van.

Multiple Entity Parcels

The PICS application provides the capability of collecting the data for property parcels that contain multiple family units and multiple structures (multiple entity). When a multiple entity parcel is selected, a second report list is created for the computer operated. The operator then records an address of the living unit, the x-y coordinate and the property characteristics for each unit of the multiple entity. As a result, an address database is created for each property record and residential unit. For apartment complexes, Yotta MVS’s field crews can usually obtain a site map from the apartment complex administration office. This map is utilized to identify each living unit in the complex. In those cases where a map cannot be obtained, the Yotta MVS field crew will physically walk to each living unit door to verify the address.
