Basic Query Using The GSA
The “Spatial Engineer 11” tutorial video provides an in-depth guide on performing queries within a specific geographic search area. This functionality is essential for users who need to focus on particular regions or areas within their spatial data without getting overwhelmed by the entirety of the database. Here’s a summary of the key points covered in the video:
- Accessing Query Options: The presenter demonstrates two methods to access the query dialogue: through the feature pull-down menu and by right-clicking in the drafting area. Both methods offer the same options for initiating a query.
- Selecting Data to Query: Users are shown how to select specific types of data they wish to query, such as the copper plant and fiber plant. The video emphasizes the flexibility of the query tool, allowing users to expand the selection menu and deselect any items they do not wish to include in their query to reduce screen clutter.
- Setting a Geographic Search Area: A critical step highlighted is setting a geographic search area to narrow down the query to a specific region. The default setting queries the entire spatial extent (the whole database), but the presenter shows how to change this to focus on one exchange boundary by using a polygon filter. This filter can be adjusted to include data either crossing into or entirely within the selected boundary.
- Executing the Query: After setting the geographic search area, the presenter executes the query, retrieving data for the copper and fiber plant within the defined boundary. This demonstrates how to efficiently focus queries on areas of interest.
- Querying Additional Data Layers: To further illustrate the query tool’s versatility, the video shows how to perform additional queries for base map data, such as building footprints and road centerlines, within the same geographic area. This is done by selecting new data layers and applying the same geographic filter as used for the plant data.
- Viewing Results: Finally, the presenter zooms in on the queried area to display the overlaid plant and base map data, showcasing how Spatial Engineer 11 allows for detailed analysis of specific regions.
This tutorial is particularly useful for Spatial Engineer 11 users looking to conduct targeted searches within their spatial databases, offering clear instructions on how to utilize geographic search areas and filters to streamline their queries.
