# What is XY tolerance?

## What is XY tolerance?

The x,y tolerance refers to the minimum distance between coordinates before they are considered equal. For a description of the default x,y tolerance, see Spatial reference and geoprocessing.

### What is the difference between XY resolution and XY tolerance?

The x,y tolerance should be coarser than the resolution. In ArcGIS the default value esri uses for the x,y tolerance is 10 times x,y resolution. If you use a tolerance of 0.1 cm you shold use a resulution of 0.01 cm. (It is possible to use every value as tolerance and resolution (e.g. 0.5, 0.12345, 0.99 …).

#### What is Z tolerance in ArcGIS?

GIS Dictionary. z-tolerance. [coordinate systems] In raster-to-TIN conversion, the maximum allowed difference between the z-value of the input raster cell and the z-value of the output TIN at the location corresponding to the raster cell center.

What is meant by the term cluster tolerance ‘?

Cluster Tolerance is the distance range in which all vertices and boundaries in a shapefile or feature dataset are considered identical or coincident. ESRI says, set the cluster tolerance to a value that is an order of magnitude less than the accuracy of your data.

What is cluster tolerance Arcmap?

A cluster tolerance is used to integrate vertices. All vertices that are within the cluster tolerance may move slightly in the validation process. The default cluster tolerance is based on the precision defined for the dataset. The default cluster tolerance is 0.001 meters in real-world units.

## Is resolution same as tolerance?

Gage tolerance is the gage’s increments of measure (also called resolution or discrimination). Subtracting the maximum and minimum diameters, the process tolerance is 0.02. In order to accurately measure these balls, you must use a gage capable of detecting several differences in this range.

### What is XY resolution Arcgis?

The x,y resolution, expressed as a very small distance, refers to the number of significant digits used to store x,y coordinate values.

#### What is Z tolerance?

The z-tolerance is the maximum allowed difference between the z-value of an input raster cell and the z-value of the output TIN at the location corresponding to the raster cell center.

What is meant by topology in GIS?

Today, topology in GIS is generally defined as the spatial relationships between adjacent or neighboring features. Mathematical topology assumes that geographic features occur on a two-dimensional plane.

What is topology in ArcGIS?

In geodatabases, topology is the arrangement that defines how point, line, and polygon features share coincident geometry. ArcGIS includes topology layers in ArcMap that are used to display topological relationships, errors, and exceptions.

## What is the difference between resolution and sensitivity?

RESOLUTION – the smallest portion of the signal that can be observed. SENSITIVITY – the smallest change in the signal that can be detected.

### What does the X, Y tolerance in ArcGIS mean?

The x,y tolerance refers to the minimum distance between coordinates before they are considered equal. For a description of the default x,y tolerance, see Spatial reference and geoprocessing.

#### When to use x, y tolerance in geodatabase?

If the x,y tolerance is less than twice the output geodataset’s x,y resolution value, an x,y tolerance of two times the x,y resolution will be used. X,y tolerances are not preserved in geodatabase versions older than 9.2.

What are the clip features in ArcGIS for?

This is particularly useful for creating a new feature class—also referred to as study area or area of interest (AOI)—that contains a geographic subset of the features in another, larger feature class. The Clip Features can be points, lines, and polygons, depending on the Input Features type.

When is use ratio policy enabled in ArcGIS?

When Use Ratio Policy is enabled, whenever a feature in an overlay operation is split, the attributes of the resulting features are a ratio of the attribute value of the input feature. The output value is based on the ratio in which the input feature geometry was divided.
