Getting Started with the Geodatabase

Exploring data in the geodatabase

After clicking the List By Data Source button the data layers in the Contents pane are rearranged and are now listed according to their source location.

Examining the feature dataset

After expanding the PublicWater feature dataset which contains thematically related features for the city water department. The three feature classes represent parts of the utilities system that delivers water to homes in the city. In the Catalog pane, the StormDrains feature class was right-clicked and Properties was chosen. In the Feature Class Properties dialog box, Spatial Reference was expanded. The same steps for viewing spatial references were repeated for PublicWater feature dataset.

Exploring the feature classes

In the Catalog pane, the StreetTrees layer is right-clicked and its Add To the Current Map. StreetTrees is right clicked and Attribute table is chosen. After closing the attribute table the StreetTrees feature class is right-clicked and fields is selected after pointing to Design then. The attribute table for SewerServiceMains is opened with the same steps used to open the attribute table for StreetTrees then Shape_Length field is examined. After closing the attribute table, the SewerServiceMains Fields view is opened the same way fields were opened for the Shape_Length field. The fields having the name Shape were examined then closed afterwards. Attribute table for the BuildingFootprints is opened and the Shape_Length and Shape_Area fields were examined. Attribute table is closed and Fields view for Parcels feature class is opened. The fields that have Shape in their name were examined, then comparing what we observed in the polygon feature class with what we saw in the point and line feature classes and then closing the Parcel Fields view afterwards.

Creation of a stand-alone feature class

In the Catalog pane, CityWater.gdb is right-clicked, then pointing to New, and choosing Feature Class. In the Define pane, following parameters were set: Name: Type Roads, Feature Class Type: Choose Line, Geometric Properties: Uncheck the M Values and Z Values boxes. After clicking next in the Spatial Reference pane, Add Coordinate System button was clicked and Import Coordinate System was chosen. StreetTrees is selected from \EsriTraining\GDB_Start\CityWater.gdb click okay. Click Next three times to accept the remaining default settings, and then click Finish. In the Catalog pane, drag Roads into the map. In the Contents pane, right-click Roads, point to Design, and choose Fields. On the Fields tab, in the Changes group, click New Field.In the new field row, set the following parameters:Field Name: Type RoadName.Data Type: Choose Text.Length: Type 55.On the Fields tab, in the Changes group, click Save. Close the Roads Fields view. Open the Roads attribute table. The structure for your new feature class is created. Your next step would be adding its features and additional attributes, which you will do later in this course.Close the attribute table.Save the project.If you are continuing to the next exercise, leave ArcGIS Pro open; otherwise, exit ArcGIS Pro.

 Create a new geodatabase

Firstly, we create a new geodatabase to hold the San Diego data, On the Insert tab, New Map is added. Map from the previous exercise is closed in the Catalog pane, the Databases folder is right-clicked and New File Geodatabase is chosen. In the New File Geodatabase dialog box, for Name, type SanDiego, and then is was Saved.

Create feature dataset

Creation of a schema for the data by creating feature datasets, in the Catalog pane, Databases are expanded and Right-clicked SanDiego.gdb, after pointing to New, and choose Feature Dataset. In the Create Feature Dataset tool, set the following parameters: Feature Dataset Name: Type Boundaries. Coordinate System: Type 2230 then click run. The process to create two additional feature datasets were repeated for

Import shapefiles into the feature datasets

In this step, you will add city polygon data that is currently stored in a shapefile to the geodatabase. In the Catalog pane, right-click the Boundaries feature dataset, point to Import, and choose Feature Class(es). In the Feature Class To Geodatabase tool, for Input Features, click the Browse button . Browse to C:\EsriTraining\GDB_Start and add the following layers: -sd_city95.shp, -sd_own.shp, -sd_tract.shp and then Click Run. In the Catalog pane, expand the Boundaries feature dataset to see the three layers that you added. Now that you have added feature classes to this feature dataset, repeat the process to add the following data layers to their respective feature datasets: Feature dataset :Education , Transportation, Shapefile: sd_colleges.shp, sd_railstop.shp and sd_rr.shp .

Import a CAD dataset into the geodatabase

CAD files appear similar to a feature dataset because there is an overarching collection, Schools. DWG, and then individual feature classes stored in it. Within the schools. DWG dataset, locate schools. Add only the schools CAD feature class to the map. In the Contents pane, open its attribute table and examine the fields. Close the attribute table. Now you are ready to import the CAD feature class into the geodatabase. In the Catalog pane, right-click the Education feature dataset, point to Import, and choose Feature Class. In the Feature Class To Feature Class tool, set the following parameters: Input Features: ..\EsriTraining\GDB_Start\schools.DWG\Point Output Location: EducationOutput Feature Class: sd_schools then click run. In the Contents pane, open the attribute table for the sd_schools feature class. Close the attribute table.Save the project.If you are continuing to the next exercise, leave ArcGIS Pro open; otherwise, exit ArcGIS Pro.

Explore the data

In the Catalog pane, expand Folders and expand the GDB_Start folder. Expand the AlachuaCounty.gdb file geodatabase. This geodatabase currently contains several items: *A feature dataset (Administrative)*A mosaic dataset (FloridaMD) *A stand-alone feature class (MajorRoads)

Examine a mosaic dataset

In the Catalog pane, right-click the FloridaMD mosaic dataset layer and choose Add To Current Map. On the Map tab, ensure that the Explore tool is selected, and then in the map, click the raster on the far left. If necessary, at the top of the pop-up window, select Aerial_2. Close the pop-up window. In the Contents pane, within the FloridaMD mosaic dataset, right-click Footprint and choose Attribute Table. In the attribute table, scroll to the right to view all the fields, if necessary. In the Contents pane, in the FloridaMD mosaic dataset, select the Image layer. In the attribute table, for the Aerial_2 raster, select the first row. On the ribbon, click the Image Layer Data tab. On the Data tab, in the Selection group, click Explore Raster Items. In the Raster Item Explorer pane, minimize the Preview section so that you can see the Raster Information section more easily. Close the Raster Item Explorer pane and close the attribute table

View raster properties for images in the mosaic dataset

In the Catalog pane, in the GDB_Start folder, locate the Aerial Imagery folder and expand it and then right-click Aerial_2.tif and choose Properties. Close the Raster Dataset Properties dialog box. In the Catalog pane, right-click Aerial_3.tif and choose Properties then close the Raster Dataset Properties dialog box and save the project and exit ArcGIS Pro.
