The geocoding process uses an algorithm to find the geographic location of addresses. First, a street segment is identified using the zip code and street name. Next, the geographic location of the address is matched using the building number to determine how far down the street and on which side of the street the building is located. Geocoding Accuracy
The locational accuracy of geocoded addresses may vary from urban to rural areas due to the algorithm used to generate the geographic locations of addresses. The algorithm assumes that the size of parcels are equivalent along a road route. This assumption tends to be more consistent in urban areas, where the size of parcels vary less than in rural areas. Consequently, the results of geocoded addresses in urban areas are usually more reliable than those in rural areas.
For example, the locational accuracy of rural addresses can be slightly off because some parcels along a rural route may be 15 acres while others may be 2.5 acres, but the geocoding algorithm assumes that the addresses are distributed evenly along the route.

17 Different Sources Comprise the Cemetery Dataset.
The following Sources were either reprojected to the FGDL Albers NAD83 HPGN map projection or if no spatial data existed they were geocoded to a statewide 2007 TeleAtlas Streets dataset. For downloaded county and district wide polygon layers the label points were created and then used for each facility.
Once the point sources were created via geocoding or reprojected existing point data they were merged into one statewide layer.
Record (facility) duplications were removed by manually viewing and editing the statewide layer's attribute table for each of the 67 counties. Where record duplication existed source information of previously corrected FDOT Districts and Regional Planning Council data took preference followed by, County data, and finally geocoded data.
Below are the data Sources as described in the Source field in the attribute table.

A note about data scale:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger.
Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.
