- Geoprocessing tools are commonly used to change the symbols of existing data in a map. F
- Some geoprocessing tools require more than one input dataset. T
- What happens as soon as you create a new model? ModelBuilder opens with a new, empty model.
- A new model must be created inside which of the following? ToolBox
- Why should models be documented? So that others using the model can understand the data created by a model
- Which geoprocessing tool creates an output dataset containing all the features from the inputs? Union
- All of the following are geoprocessing operations, except one. Save a map
- When would you choose to build a model instead of running tools from their dialog box? When the workflow involves many processes performed in sequence
- When the workflow involves many processes performed in sequence T
- Some geoprocessing tools require more than one input dataset T
- What is a building block? A process
- In a model, what do the connecting arrows indicate? How elements and processes are related to each other.
- All of the following are geoprocessing operations, except one? The element has successfully run
- What is an efficient way to delete the intermediate data created by a model? Flag output elements as intermediate when you build the model, then delete all the intermediate data after you run the model.
- You have created a new toolbox and now you want to build a model inside it. What must you do first? Create a new, empty model
- Buffer A zone of a specified distance around a feature or features. Buffers are useful for proximity analysis (for example, finding all stream segments within 300 feet of a proposed logging area).
-
- Clip An operation that extracts the features from one layer that reside entirely within a boundary defined by features in another layer.
- Element A component of a model. Elements can be variables, such as input and derived data, or tools
- Geoprocessing A GIS operation used to manipulate data stored in a GIS workspace. A typical geoprocessing operation takes an input dataset, performs an operation on that dataset, and returns the result of the operation as an output dataset. Common geoprocessing operations are geographic feature overlay, feature selection and analysis, topology processing, and data conversion. Geoprocessing allows for definition, management, and analysis of information used to form decisions
- Intermediate data Data produced by a geoprocessing operation which is used as the input for another operation.
- Intersect Intermediate dataData produced by a geoprocessing operation which is used as the input for another operation.IntersectA geometric integration of spatial datasets that preserves features or portions of features that fall within areas common to the input datasets.
- Models An abstraction and description of reality used to represent objects, processes, or events
- Overlay Superimposing two or more maps registered to a common coordinate system, either digitally or on a transparent material, for the purpose of showing the relationships between features that occupy the same geographic space.
- Process A tool and its parameter values. One process, or multiple processes connected together, creates a model.
- Union A topological overlay of two polygon feature classes that preserves features that fall within the spatial extent of either input dataset; that is, all features from both datasets are retained.
