Over the next several weeks, KGIS will version and enable archiving on the 24 landbase feature classes. This will allow us to edit the landbase data and update it based off the 2014 aerial orthophotography and subsequent years. We will capture those edits in an archive so we can look at the data changes overtime.  KGIS will start with the High-Priority Planimetry Features outlined in the Strategic Plan for Landbase Update Program .

The National Flood Hazard Layer (NFHL) dataset represents the current effective flood data for Knox County.  This dataset is a compilation of effective Flood Insurance Rate Map (FIRM) databases and Letters of Map Change (LOMCs). KGIS received the data in December 2013, but upon the initial review of the dataset it had large amounts of missing data. After several months of revisions by FEMA, KGIS finally received a finished dataset. Although several database table/layer changes have occurred since the last update in 2007, we have been able to display the data using the same symbology KGIS has used for the last couple of years. Please go to KGIS Maps-->Maps--> Planning and Zoning Maps--> and Click on FEMA Flood Map or click here. READ MORE

The Mapunit Aggregated Attribute table records a variety of soil attributes and interpretations that have been aggregated from the component level to a single value at the map unit level. They have been aggregated by one or more appropriate means in order to express a consolidated value or interpretation for the map unit as a whole. One field that is very useful for Storm Water Runoff is the HYDGRPDCD (Hydrologic Group - Dominant Conditions), which is a grouping of soils that have similar runoff potential under similar storm and cover conditions. This column displays the dominant hydrologic group for the map unit, based on composition percentage of each map unit component.
