Data Management

　　◆  Visual spatial data management

SuperMap Desktop GIS products have an easy-to-use workspace manager to organize datasources, datasets and maps. This manager is composed with four components: data view, map view, layout view, and resource view. The user can not only create, open, close and save a workspace, data source, dataset or map via the shortcut menus, but also sort, browse, copy datasets, etc. Besides these, the extra data management capabilities are listed as below:

　　　○ Support for SDB, SBD+, DGN, DWG, DXF, SDX+ for Oracle, SDX+ for SQL Server, SDX+ for Sybase, SDX+ for DB2 and SDX+ for DM3.
　　　○ Batch creating dataset.
　　　○ Drag and drop operation.

　　◆  Data conversion

SuperMap's data conversion tools support:

　　　○ Vector formats (.dxf of AutoCAD, .e00 of ArcInfo, .mif of MapInfo, etc.)
　　　○  Binary formats (Coverage of ArcInfo, .tab of MapInfo and so on.)
　　　○  Raster image formats (.img of Erdas, .tiff of Geo, ECW and MrSID.)

　　◆  Topology

When doing system analysis or maintenance in public transportation, underground pipe, electricity, communication and cable television related job, you might need to work with the network data. These network data consist of nodes and arcs, and also complex spatial topology relationships among the network elements. For example, streets interconnected to each other at street intersections, pipes connected with valves, highways connecting to cities. In GIS, those relationships are built with topology in the network model. The topology functions provided by SuperMap desktop products include:

　　　○ Generate network dataset.
　　　○ Maintain topology relationships automatically.
　　　○ Build polygons automatically.
　　　○ Perform topology processing for overshoot, undershoot, pseudo-node, adjacent vertices etc.

Data Query

This is a common function in GIS software, and used for the routine tasks in the GIS projects. SuperMap GIS provides multiple query methods for users to find and browse the specified spatial and attribute information. The main functions include:

　　◆ Bilateral query between spatial data and attribute data.
　　◆  Integrated query cross layer of multiple objects based on both spatial and attribute conditions.
　　◆ Find and replace text like working in a word document.
　　◆ Fully support for SQL scripts, like group, sort and statistical analysis of query result.

Spatial Analysis

SuperMap Deskpro delivers many spatial analysis functions that assist decision makers and analysts to explore information behind the spatial data.
The analysis functions are:

　　◆ Distance, area, and angle measurement:

SuperMap Deskpro allows users to measure the distance along points, the area formed by points and angles in any directions on the map. When turning on SuperMap's Smart Snapping option, the user can locate their interested places with the accurate distance, area, or azimuth.

　　◆ Buffer analysis:

The user can create a buffer zone not only for each single point, line or polygon object, but also for a group of those objects. The buffer analysis is mostly used for assistance in environmental monitoring, emergence control, road design and commercial analysis etc.

　　◆ Overlay analysis:

SuperMap Deskpro provides six types of overlay analysis: clip, erase, union, intersect, identity and symmetric difference. The user can perform several types of overlay analysis between two datasets to obtain the desired result.

　　◆ Network analysis:

The network analysis plays an important role in satellite navigation, transportation, communication and other network design. Therefore, SuperMap Deskpro provides tools for optimal path analysis, adjacent node, critical node/edge, connected node/edge analysis, service area analysis, closest facility search, resource allocation and so on.

　　◆ Grid analysis:

This function offers surface analysis, hydrological analysis, grid statistics, and algebraic operations.

　　◆ 3D modeling and analysis

SuperMap Deskpro supports rapid construction of Triangulated Irregular Network (TIN) and 3D surface model by using contour and discrete 3D points, conversion from TIN to DEM, and contour calculation by using TIN.

　　◆ Slope/Aspect calculation

Slope/aspect value at any point of a 3D model and 3D coordinates (e.g. x, y, and z)of a specified point can be obtained from this analysis. All of this processing is performed in a 3D window. It helps users to easily create 3D profile, perform flood analysis and so on.

Map Layout

SuperMap Deskpro offers map layout functions in the following aspects:

　　◆ Exporting maps to raster datasets or image files:

Maps can be saved as raster datasets or an image (.bmp and .jpg) for the further processing, printing, and publishing.

　　◆ Layout printing, multi-page bitmap exporting and frame printing.

Layout printing, working the same as the standard Windows printing, can be printed on laser printers, ink jet plotters, or other printing devices. Paper size, source, orientation, and the other parameters are able to be set according to the user’s need. If the layout size is larger than the paper size, the system will automatically execute multi-page printouts.

　　◆ Selectable mapping elements, such as map frame, scale bar, north arrow, etc.
