Implementation planning of application projects: software and hardware configuration

After the application project starts, it is necessary to carry out the implementation planning. At this stage, the main task is to determine the system hardware and software design. If the system is not completely self-developed, software configuration should be carried out in the process of software design, otherwise the overall design of software should be carried out。

When configuring software and hardware, the main factors to be considered are:

  1. System data volume;

  2. Number of users and concurrent access;

  3. The existing network environment;

  4. Investment scale;

  5. The position of GIS application in the whole system is whether it is a pure GIS system or a comprehensive information system combined with other systems。

These factors have been basically determined in the strategic planning stage. At this time, software and hardware devices should be further selected according to these factors. In the process of hardware and software configuration, in addition to the above factors, we can refer to the following principles:

  1. Don’t only pay attention to hardware, but ignore the choice of software;

  2. Protect existing investments, including software, hardware, data, etc;

  3. Ensure the scalability of the system;

  4. Consider the development direction of technology;

  5. If the secondary development is to be carried out, the secondary development support capability of the software should be emphasized;

  6. Focus on whether the software and hardware functions can meet the needs of the project;

  7. Performance is also an important factor that can not be ignored。

  8. The function of hardware and software must satisfy the system requirements, and the performance indicators can be defined in advance. Usually, the performance of the system is directly related to the amount of investment. This requires determining an optimal performance/investment ratio according to the amount of investment, so as not to cause waste or fail to meet the project requirements。

The following are some specific suggestions for the configuration of software and hardware of GIS (Table 15-3)。

Table 15-3: Some specific references for software and hardware configuration of GIS

Project

Specific consideration factors

Software

Data volume

Distribution of data

Existing data

Need for secondary development

Systems need to collaborate with other software

Existing hardware and software platforms

Need to be integrated with the Internet

Hardware

Large amount of data and need to be shared

Data needs to be backed up regularly

Lots of data entry

Map output

High-quality, large-scale map output

Data acquisition

Mobile computing

Selected software

Network

LAN

Remote access

Access to Internet

If the amount of data is large, we should pay attention to the performance of the software in dealing with the large amount of data, and whether it supports galleries or not

If the management of data is distributing, software is needed to support the network

Whether the software can read into existing data smoothly

Does the software support secondary development and support methods (API, control, macro language)

Does the software support the database

Software must be able to run on existing hardware and software platforms

Whether the software supports the Web or not, in specific ways (ActiveX, Java, etc.)

Select Data Server

Tape recorder, optical disc recorder

Scanner, digitizer

Colour inkjet printer

Inkjet plotter, other high-end plotters

GPS receiver, flat panel mapper

Notebook computer

Hardware platform to enable software to run well

Cable/twisted pair, hub

Dial-up network support
