Study Notes
ArcGIS Tools: Append, Merge, Union, Dissolve, Buffer, and Clip
-
Append:
- Combines features from one or more datasets into an existing dataset.
- Modifies existing data.
- Important considerations: Target dataset must exist; tool modifies input data.
- Handles differences in field structures using 'Skip and warn if schema does not match' and 'Field Map' options.
- Cannot combine datasets of different geometry types (points and polygons).
-
Merge:
- Combines multiple feature classes (points, lines, polygons) or tables into a new dataset.
- Preserves original datasets.
- Important considerations: All input datasets must have the same geometry type; 'Field Map' aligns fields.
- Creates a new dataset; does not modify input data.
-
Union:
- Combines features, creating a new dataset including overlapping and non-overlapping areas.
- Merges attributes of overlapping features.
- Primarily for polygon feature classes.
-
Dissolve:
- Aggregates features with a common attribute to create single features.
- Can handle polygon, line, and point data.
- Allows statistical summaries (e.g., sum, mean, count) for other attributes.
- Reduces the number of features by merging those sharing a common attribute.
-
Buffer:
- Creates an area (buffer) around features within a specified distance.
- Supports points, lines, and polygons.
- Options: fixed distance, variable distance based on attribute, multi-ring.
- Useful for identifying areas/zones around a feature.
-
Clip:
- Extracts features based on boundaries of another dataset (clip layer).
- Preserves attributes of clipped features.
- Clip layer must be polygonal; operates on points, lines, and polygons.
- Resulting dataset (output) contains features within the clip boundary.
Raster vs. Vector Data
-
Raster:
- Uses grid cells with uniform sizes.
- Each cell has a value associated with its location.
- Suitable for large datasets and trend analysis, but less precise for detailed coordinates.
- Advantages: fast processing for large datasets, simplified mathematical computations.
-
Vector:
- Represents features with points, lines, and polygons with topological relationships.
- Generally more compact in storage than raster data.
- Features: more precise coordinates, easy to represent topological relationships, efficient overlay operations.
