java.lang.Object
- com.supermap.data.DatasetType

```
public class DatasetType
extends java.lang.Object
```
Defines dataset types.
A dataset is a collection of related data stored together. According to the types of data, there are vector dataset, raster dataset, and the dataset designed for specific problems, such as topology dataset, network dataset etc. For different features may have different spatial representations, the vector dataset includes point dataset, line dataset, region dataset and so on, and the features with the same spatial representation and function will be organized together. Raster dataset includes grid dataset and image dataset.

Fields
Modifier and Type	Field and Description
`static DatasetType`	`CAD` CAD dataset is used to store multiple kinds of datasets.
`static DatasetType`	`GRID` The grid dataset is mostly used to do some analysis based on raster, so the value of a cell represents certain attribute of a geographic feature, such as elevation, rainfall, etc.
`static DatasetType`	`IMAGE` The image dataset belongs to the raster dataset, such as image map, multi-wave image and photo.
`static DatasetType`	`LINE` The line dataset is used to store the line objects, like the distributing of rivers, roads and national boundaries.
`static DatasetType`	`LINE3D` Line3D dataset.The Line3D dataset is mainly used to store the 3D line objects.
`static DatasetType`	`NETWORK` The network dataset is used to store the dataset with topological relationship in network, such as the transportation network.
`static DatasetType`	`NETWORK3D` 3D network dataset.The dataset is mainly used to store the 3D network data, such as the building, pipe and so on.
`static DatasetType`	`POINT` The point dataset is used to store the point objects, such as distributing of the disperse points in this figure.
`static DatasetType`	`POINT3D` Point3D dataset.The Point3D dataset is mainly used to store the 3D point objects.
`static DatasetType`	`REGION` Polygon dataset is used to store region objects, like the distributing of residential areas and administrative area.
`static DatasetType`	`REGION3D` Region3D dataset.The Region3D dataset is mainly used to store the 3D region objects.
`static DatasetType`	`TABULAR` The tabular dataset is mainly used to store and manage the pure attribute data that describe the information of the characters and shapes of the surface features, such as the length and width of the river.This dataset does not contain graphics data in it, namely the dataset can not be displayed in the map window as a layer.
`static DatasetType`	`TEXT` The text dataset is used to store the text objects, such as the text of the annotation.
`static DatasetType`	`VECTORCACHE` vector cache dataset
`static DatasetType`	`VIDEO` VIDEO dataset
`static DatasetType`	`WCS` WCS dataset, which is used in image multispectral map
`static DatasetType`	`WFS` WFS dataset.
`static DatasetType`	`WMS` WMS dataset, which is used in online real map

  - TABULAR
```
public static final DatasetType TABULAR
```
    The tabular dataset is mainly used to store and manage the pure attribute data that describe the information of the characters and shapes of the surface features, such as the length and width of the river.This dataset does not contain graphics data in it, namely the dataset can not be displayed in the map window as a layer.
  - POINT
```
public static final DatasetType POINT
```
    The point dataset is used to store the point objects, such as distributing of the disperse points in this figure.
  - LINE
```
public static final DatasetType LINE
```
    The line dataset is used to store the line objects, like the distributing of rivers, roads and national boundaries.
  - REGION
```
public static final DatasetType REGION
```
    Polygon dataset is used to store region objects, like the distributing of residential areas and administrative area.
  - TEXT
```
public static final DatasetType TEXT
```
    The text dataset is used to store the text objects, such as the text of the annotation.
  - IMAGE
```
public static final DatasetType IMAGE
```
    The image dataset belongs to the raster dataset, such as image map, multi-wave image and photo. The image dataset is used to be displayed or used as the base map, so the value of a cell is the value of a color or the value of an indexed color.
  - CAD
```
public static final DatasetType CAD
```
    CAD dataset is used to store multiple kinds of datasets.
  - NETWORK
```
public static final DatasetType NETWORK
```
    The network dataset is used to store the dataset with topological relationship in network, such as the transportation network. The network dataset is different with the point dataset and the line dataset. The network dataset contains the line objects, the note objects and the topological relationship between them. The network dataset is used for network analysis such as finding the shortest path, performing a service area analysis, closest facility analysis, location-allocation analysis, bus transfer, adjacent node and connected node analysis.
