The LOMA point layer indicates coordinates for Letters of Map Amendment, which can affect flood zone determination without a map change. Please be aware that LOMA point layer is provided ‘as is’ and that there are several issues that must be considered before using this information. The first is its positional accuracy. Where the point is shown on the map may, or may not, be totally accurate as there are a variety of methods that can be used to translate a mailing address into a geographic coordinate (geocoding). The second is the completeness of the dataset. This point layer only includes LOMAs that have a coordinate associated with them. There are a number of LOMAs that have been processed by FEMA which do not have any type of a coordinate associated with them and those LOMAs are not included within this data. The contents of the LOMA shapefile are derived from user input in eLOMA(within the MIP) as well as SOMA(also within the MIP), which is converted by the FME model into the shapefile. This process runs on a nightly basis automatically during the week. In addition, there is an https location where the public can download the LOMA Point shapefile and the metadata upon request from MIP help. |
