Hazus | Import User Defined Facilities (UDF)

boom, whoosh, drip, splash, sparkle [ upbeat music fades in ] Welcome to the “Import User Defined Facilities”
video tutorial. In this video, we will provide an overview
of User Defined Facilities, or UDF, and walk through how to prepare and import UDF data
directly into a study region. UDF are custom, site-specific data used to
supplement or improve the accuracy of the generalized inventory data that are made using
non-Hazus datasets and information. Users can create custom UDF data from a variety
of sources including assessor data, site surveys, or other sources. The level and type of data needed to build
UDF depend on which hazard you intend to model, as different building attributes are required
for each hazard. Further information on hazard-specific attributes
needed for UDF can be found in each hazard’s user manual available via the link in the
video description. While it is recommended that you enter UDF
for use by Hazus via the Comprehensive Data Management System, you may want to import
UDF data directly into a study region if you are updating a small number of records, if
you don’t want to permanently update your state dataset, or if your data does not meet
the attribute information requirements of
CDMS. [ upbeat music ] Before importing your UDF into your study
region, you must take several preparatory
steps. First, your data must be in a personal geodatabase
or “.mdb” file type. No other file formats will be recognized by
Hazus for importing UDF data in this method. Second, your data must be projected in the
WGS_1984 coordinate system. Third, your data file should be located in
your HazusData folder. If it is located in an outside folder or on
a server, Hazus may have a problem connecting to your file. Once you have taken these preliminary steps
to prepare your data, you are ready to import your UDF into Hazus. [ upbeat music ] We are going to import user-defined data for
a flood model in Arapahoe County, Colorado. The steps demonstrated in this video are specific
to flood, but are similar to the processes for importing UDF data for other hazards. To import data, begin by opening the Inventory
menu and selecting “User Defined Facilities”. This will bring up the User Defined Facilities
dialog box. Note that if you have previously imported
UDF data using CDMS, they will be displayed here. To begin the import, right click in the blank
grid and select “Import”. A warning message will appear advising that
the import file must be saved on a local drive, as we mentioned before. Click “Ok” and navigate to your UDF data in
your HazusData folder. Click “Open”, then select the table within
your file that contains the UDF data you would like to import and click “Ok”. Now that Hazus knows what UDF data you want
to import, you will have to match field names between your source data and the
default Hazus database to ensure that the attribute data transfers correctly. To do this, select a source field name from
the left column and then either select and click “Add” or double click the name of its corresponding destination field in the right
column. The matched attribute fields will be moved
to the lower “Mapping Results” section. Repeat this for the remaining attributes. Any attribute fields you leave unmatched will
be populated with default values. Please note, you must match the latitude and
longitude fields for a successful UDF import. Messages may appear if the source and target
attribute field types do not match exactly. A prompt will indicate that your source field
is larger than the target field and may cause the import to not work properly. A warning message will appear if the field
selected from your source database has an incompatible datatype with the selected target
field in Hazus. You can resolve this issue by modifying the
datatype in your original source database
outside of Hazus. The datatype for each attribute can be found
in each hazard’s User Manual available from the FEMA website. When you have finished mapping your data fields,
you can click “Save” to save the mapping scheme that you have just created. If you plan to update this study region again,
it’s recommended that you save the field matching file since this will allow you to more easily
import UDF in the future. Click “Ok” and the data will be imported into
the study region. Your UDF data will appear for you to review
and edit further. Any field with black text is editable, meaning
we could edit the year a building was built, its square footage, or other information. You can also visually confirm the locational
accuracy of your UDF by displaying the facility locations on your study region map. To do so, select a column and click the “Map”
button. Then, click “Close” to return to your map. If you made any changes, a prompt will appear
asking if you would like to save your changes. Click “Yes”. With that, your data is now ready for use
and you can explore your imported facility data on the map of your study region. Once you’ve imported UDF data and are satisfied with
the set parameters, you are now ready to run the analysis. Remember to check the UDF box when you run
your analysis to include this new data. Congratulations! In this video, you learned
about UDF, including how to prepare and import UDF data directly into a study region. Look for more Hazus video tutorials on the
FEMA YouTube channel. [ upbeat music fades out ]
