介绍数据检查
To ensure that you're dealing with the right information you need a clear view of your data at every stage of the transformation process.
Data Inspection meets this need: it is the act of viewing data for verification and debugging purposes,before,during,or after a translation.
What Can Be Inspected?
A number of different aspects of data may be inspected,including the following:
- Geometry: Is the geometry in the correct spatial location?Are the geometry types correct?
- Symbology: Is the color,size,and style of each feature correct?
- Attributes: Are all the required attributes present?Are all integrity rules being followed?
- Format: Is the data in the expected format?
- Schema: Is the data subdivided into the correct layers,categories or classes?
- Quantity: Does the data contain the correct number of features?
- Output: Has the translation process restructured the data as expected?

Hi.I'm Chef Bimm and I'm here to help you cook up some tasty data translations. I have a great recipe for loading CAD files into a Building Information Model.Inspecting the ingredients...I mean data...before I use them lets me detect problems before they affect the translation. Features in the wrong source layer could need the whole process to be repeated.Data Inspection saves me that hassle. |
