Building the Geodatabase with ArcCatalog Build LandRecords DB

Create the LandRecords file Start ArcCatalog Navigate to your data download: C:\ESRIPress\GIST3\Data Right click, > New > and create a New folder called MyAnswers Right click MyAnswer and then – > New > File geodatabase Call the new file: LandRecords.gdb

Create a feature dataset We have a feature dataset in our design that contains two feature classes – The dataset requires two things: a name and a spatial reference which ties to a location on the globe Oleander is in Central Texas, so the reference must be typical of this area – Here we need to decide if our data needs to be stored as projected or unprojected – Also need to define the extent of the dataset

Create the dataset Right click the LandRecords.gdb file, and Select New, and then click feature dataset Type the name of the dataset as: PropertyData and click Next Then set the spatial reference in the New Feature Dataset dialog > Projected Coordinate System > State Plane > NAD 1983 (CORS96) (US Feet) > select Texas N Central FIPS 4202

Create the feature classes Now that we have the dataset, we create the two feature classes inside the dataset Each feature classes requires: – A name (from the design form) – A spatial reference (which is set at the dataset level) – A geometry type This cannot change later, so make it correctly!

Create the Parcels Feature Class Right click on the PropertyData dataset > New> Feature Class Type the Name and Alias of the New Feature class in the textboxes Select its type as Polygon Feature in the dropdown list > Next > accept the defaults Now define the fields in the feature class

Enter Fields for the Feature Class Two fields are already defined – ObjectID with Object ID Data Type – Shape with Geometry Data Type Add other fields for the Parcels feature class: – Enter Field Name, Data Type, Alias, Allow Null values (default is Yes), Default values (if any), and Length (default is 50 for Text) Do this for all fields … – See the worksheet in the previous slide! – Do not worry about domains and subtypes at this stage – > Finish // creates the feature class; adds it to the feature dataset

Enter the LotBoundaries Feature Class Repeat the process of adding the LotBoundaries feature class to the dataset Right click on PropertyData dataset > New > Feature Class Define its name and Alias Give it a line feature type > Next> default Add the fields to the LotBoundaries feature class – Add LineCode under the ObjectID and Shape fields > Finish

Create the Domains So far, we have defined our dataset and its two feature classes and their fields Now, we need to introduce data integrity for the feature classes Domains are defined at the geodatabase level Two rules regarding domains: 1.Give a specific (even long) name to the domain to indicate its purpose 2.Never alter someone else’s domain to fit your needs! If you modify an existing one, the dataset using it will not work anymore – So, always create your own domain

Create the domain Right click the LandRecords.gdb > Properties> Domains Tab Type the domain name (ParcelUseCodes) and description (Use Codes for Parcels) Select Text for field type. Select Domain types (there are two types): 1.Coded Values (is a list of values) Text can only be Coded values (this is default Numeric fields can also be used for Coded Values 2.Range, allows setting the first and last values between which the entered data can fall (works only with numeric type) Enter A1 under the Code column in the Coded Values Pane Enter its Description>Apply after each entry Repeat for all codes …

Create the other two domains Repeat the process for the ParcelLineCodes The StTypeAbbrv domain imports values from a file (Data\Suffix.txt) For the ParcelLineCodes, right click on the LandRecords.gdb, and then > Properties Enter the domain name and description under the existing domain, and define the field type and coded values

Create a domain from a table For StTypeAbbrv domain we bring street suffixes from an existing database This first requires finding the ‘Table to Domain’ tool in ArcCatalog that allows us to do such a thing Use Search (Ctrl+F) to find the Table to Domain tool (or > Windows > Search) Double click the item in the returned list

In the dialog, browse to the Suffix.txt file in the Data folder C:\ESRIPress\GIST3\Data\Suffix.txt Select SuffuxAbbrv under Code Field, and SuffixType under Description field Select the gdb under the Input Workspace C:\ESRIPress\GIST3\Data\MyAnswers\LandRecords.gdb Type StTypeAbbrv under Domain Name Type Street Type Abbreviations > OK > LandRecords.gdb > Properties You can see the SuffixAbbrv domain. Click on it to see the Street suffix codes
