SuperMap FieldMapper

Mobile GIS has become a trend of GIS development, and it has a wide application in military, surveying and mapping, medical care, automobile navigation etc. Recently GPS vendors launch various palmtop data collection devices integrated with GPS and PDA functionalities with increasingly high precision. For example, MobileMapper CE of Magellan has the post-processing accuracy of 30 millimeters. These devices are widely used in professional data collection of many industries (such as surveying and mapping, land use, electric power). However, it is required that the software updates with the progress of hardware. The existing field data collection systems based on Mobile GIS in current market are prone to fall into two extremes: either too general-purpose to meet professional needs, or too professional to accommodate the varied requirements of industries. To address these issues, SuperMap provides professional field data collection software-SuperMap FieldMapper, which combines generality and professional ability perfectly.

Technical Features

　　◆ SuperMap FieldMapper is a professional field data acquisition software integrated with GPS. It can be widely used in power line patrolling, land resource survey, aerial survey, urban management, etc.

　　◆ Ease of use, with user-friendly interface. FieldMapper is an easy-to-use system with user-friendly interface. The system give full consideration to the size of PDA screen, and arrange the toolbars reasonably, while reduce the screen space occupied by toolbars, dialogues and so on to the maximum extent.

　　◆ Multiple manners for high efficiency data organization. PMR is a dedicated file format defined by SuperMap for mobile data collection. It is well served in data access and display, and applies to background map with massive data volume. PM2 is an optimized data format defined by SuperMap for data editing. High efficiency data organization can be achieved by combining PM2 and PMR.

　　◆ Support for data import and export in multiple formats. The import and export function of FieldMapper support multiple data formats, for example, SDB, DXF, MIF, SHP and so on. Meanwhile, more types of data formats can be supported by employing other SuperMap products.

　　◆ Support for symbol customization. Symbol customization function is a common shortage of lots of software; FieldMapper provides powerful symbol customization tools, in which the user can save custom marker, line and fill symbols to parameter file for further use.

　　◆ Customization for applications in different industries. FieldMapper supports custom collection parameters, and the user can define desired map layer, attribute field information, entities etc. for use during data editing. When collecting pre-defined entities, the user need not to create new map layer, set field information, or choose symbols for entities etc., which greatly reduce workload, and meanwhile the standardization of data collection can be promised.

　　◆ Collection and update of multimedia attribute data such as voice, picture etc. The user can associate the multimedia data (voice, picture and so on) with entities, and when clicking an entity, the corresponding tool software will be launched to present the multimedia files.

　　◆ Support for high resolution image data. High resolution remote sensing images are supported in PMR and PM2. The SIT (SuperMap Image Tower) technology of SuperMap supports rapid display of GB level image data on PDA.

　　◆ Unique Value thematic map. In most software of this kind, only one symbol style can be set for a map layer. FieldMapper provides unique value thematic map function, and the user can set various styles for entities on one layer.

　　◆ Post-processed differential GPS. Real-time differential GPS can achieves sub-meter positioning accuracy, and after difference operation, the precision can reach 30 millimeter.

System Requirements

　　◆ CPU: CPU based on ARM architecture, including
　　　　—Intel® (StrongARM®, XScale™)
　　　　—Samsung
　　　　—Texas Instruments (OMAP)
　　　　—Atmel

　　◆ Operating System:
　　　　Windows Mobile:
　　　　—2003, 2003 Second Edition, 5.0

　　◆ Windows CE:
　　　　—4.2, 5.0
　　　　 Memory: 64MB RAM

Main Functionality

　　◆ Data Browse:

　　　○ Map browse: Zoom in/out, pan, GPS centerize, full screen, setting map center.

　　　○ Layer management: Display the name, type, number of objects, maximum/minimum extent etc. of the dataset, set field information and layer style.

　　　○ Attribute viewing: Set field value, link picture, voice, browse and change coordinate value.
Selecting graphics: select by point or dragging rectangle

　　　○ Spatial measurement: distance, angle and area measurement

　　　○ Advanced query

　　◆ Graphics Drawing

　　　○ Simple graphics drawing: point, line, area and text.

　　　○ Entity drawing: Draw the entity configured by the user in Tools program. The advantage is the entity to be drawn will be rendered with the style automatically, and one layer can have multiple styles.

　　　○ COGO (Coordinate Geometry): Point interpolation in polar coordinate system, angle intersection, boundary intersection

　　　○ Support for pause and resume functions during drawing.

　　◆ Graphics Editing

　　　○ Delete/move

　　　○ Extend/clip

　　　○ Change line direction

　　　○ Erase polygon

　　　○ Add/delete vertices

　　　○ Add vertices

　　◆ GPS

　　　○ GPS settings: Set the port, baud rate of GPS, set the number of coordinates when recording single point, number of coordinates when recording inflexion, time interval when recording points continuously.

　　　○ Displaying of Ephemeris state

　　　○ Recording/displaying GPS track

　　　○ Compass navigation

　　　○ Recording original data

　　◆ Functions on PC

　　　○ Forefront map configuration

　　　○ Data editing

　　　○ Data conversion

　　　○ Symbol customization

　　　○ Professional parameter creating

　　　○ SIT conversion
