Issues before introduction

Since 20, Kawaguchi City has been operating ASP-type public GIS and in-house GIS.

It was a system that was used by about 30 sections within the agency and had about 200 layers, but it had been a while since it was introduced, and in 31, the purpose was to introduce convenient and new functions that are useful for business and to reduce costs. It was decided to replace it with.

Points that were emphasized at the time of introduction

Upon introduction, we received the following requests from within the agency.

  • Easy to operate and easy to understand
  • Being able to input and output data from the new geodetic system and the old geodetic system
  • Data such as SHP and CSV can be input / output with simple operation.
  • Easy density analysis and population analysis
  • Easy data linkage with public GIS
  • Symbol icons can be easily created and used
  • Easy address matching
  • Being able to easily create and publish open data
  • Being able to easily and quickly update public information in the event of a disaster, etc.

Furthermore, in order to further promote the use of GIS, emphasis was placed on human resource development within the agency.

Background from introduction to operation

  • February 31 RFI announcement
  • March 31 (2019) RFI Implementation Ordinance July (3) July Specifications Announcement
  • July Proposal for the first year of Reiwa (2019)
  • August, 2019 Reiwa selection and system construction start
  • Operation started in March, 2nd year of Reiwa (2020)

System selection points

As a result of the proposal, Informatics was selected.

Before the replacement, the development of GIS human resources was slow in terms of usability and support, but the fact that Informatics presented a concrete solution was particularly highly evaluated at the time of selection.

For example, creating GIS content is not something that only system engineers can do, but it seems that the staff themselves could easily do it, and staff training is held once a year, with two courses for beginners and intermediates. The proposal was well received.

In addition, compared to the system they had previously used, the system was highly praised for not only basic functions, but also for its unique analysis functions, and for its intuitive and easy-to-understand interface specialized for municipal operations.

Evaluation of the system

The replaced in-house integrated GIS has received high praise from each division, with comments such as ``fast operation,'' ``intuitive and easy-to-understand operation,'' and ``smooth coordination with public GIS.''

In particular, in FY2, when it was introduced, group training for staff could not be held due to measures against the new coronavirus infection, but Informatics was able to flexibly respond to requests from within the agency under these circumstances. , provided training videos for e-learning.

A participant in the e-learning training video said, ``It's more convenient than group training because you can watch and confirm it at your own pace!''

Benefits

In the use of GIS for the census, which is carried out every five years, a large amount of polygons are combined / divided, layers are integrated, and attribute values ​​are changed / added / deleted, which has taken a lot of time. However, after the introduction of this system, the work time has been reduced to about half of the conventional one because it is easy to operate.

On the other hand, the Information Policy Division has taken a considerable amount of time to follow up on things that were difficult to deal with by the field department alone, but in the census of the second year of Reiwa, we never made technical inquiries. I didn't receive it.

You are glad that you were able to procure a good system that allows you to complete your work only in the field department.

The Next Development

The open GIS "Kawaguchi Guide Map", which was renewed and opened together with the integrated GIS within the agency, can be exported in various formats such as SHP, CSV, and KML by user operation with standard functions, so it can be exported by citizens and corporations. We will also focus on enhancing the content so that you can use it, and we would like to further promote cooperation with the open data business.

In addition, in April 3, the new coronavirus vaccination venue map New content is being added as soon as possible.Furthermore, it is also being considered to promote citizen posting functions from smartphones.
