Based on research and practice of indoor and outdoor spatial information modeling, BIM technology, and spatial information integration in recent years, experts gave detailed reports on research background of indoor and outdoor spatial information fusion and application in the big data era, indoor and outdoor three-dimensional spatial information collection, indoor and outdoor spatial information fusion, indoor and outdoor integration applications and prospects.

2) Participate in exchange meeting in Yinchuan

On August 17, experts of the project team went to Yinchuan, Ningxia Province to report and discuss the exploration and practice of surveying and mapping technology in the spatio-temporal big data age. Starting with how to survey a city, the report was delivered around surveying and mapping industry and spatio-temporal big data, surveying and mapping techniques exploration, smart application and practice in new situation.

Technical Presentations in Chongqing

Construction achievements presentations and technical exchanges were carried out in government departments, enterprises and public institutions. Relevant science popularization lectures on Smart City and Intelligent Community were conducted to:

1) communicate with related organizations of government departments
2) communicate with enterprises and public institutions
3) conduct lectures in communities
4) To conduct lectures in universities

Spatial Information Products Exhibition

Science popularization activities with special theme

This year was the first year that the Surveying and Mapping Law of the People’s Republic of China was carried out. With this opportunity, exhibition activities of the 2017 publicity day were held on Guanyinqiao Square on 29 August 2017. There were four exhibition areas, including display panel exhibition area, equipment capability of surveying and mapping exhibition area, experience area of surveying and mapping frontier, and service area of legal consultation. The subjects embrace three-dimensional digital city, fantastic exhibition of future life, low-altitude unmanned aerial vehicle (UAV) aerial photography, etc.

1) Three-dimensional digital city - a three-dimensional digital city comics exhibition and its demonstration equipment were set up in the exhibition area. With the form of cartoon and dialogue, the comics exhibition presented the function of three-dimensional digital platform. The technicians offered on-site demonstrations and guided the public to personally operate it.

2) Fantastic exhibition of future life - with the platform of space-ground integration real-time system, fantastic exhibition of future life used the real-time map of sky, ground, indoor and outdoor as the carrier to display three-dimensional geographic information and social economic information from different perspectives. A fantastic and vivid world has been presented to the audience by three-dimensional advanced multimedia technology.

3) Low-altitude unmanned aerial vehicle (UAV) aerial photography - technicians set up UAVs in the original unit base of No. 231, electrical measure village, and conducted demonstrations of on-site operation of UAVs, and presented achievements of flight images. In terms of surveying and mapping, planning, emergency monitoring and ecological protection of low-altitude UAV aerial photography, technicians have introduced them in detail.

Interactive experience of Smart City

The science popularization program carried out demonstrations and interactive experiences in the 3D demonstration hall, providing VR experience for the public with wearable devices, leading the public to visit the smart city experience center of Nan’an District.

The 3D demonstration hall - aAs a multifunctional demonstration hall of our institute, the 3D demonstration hall is equipped with circular-screen projection system, which providing the audio and visual environment of immersive virtual simulation. The demonstration hall has deployed Geo-King 3D digital city platform, Love Chongqing, public service platform of Chongqing’s geographic information, space-ground integration real-time map system, spatial information service cloud platform of Smart City and so on, which have provided conditions for the interactive experience. Here we have made demonstrations and interactive experience for government officials, staff from enterprises and public institutions, experts and scholars, students from universities and the public who came to our institute for exchanging, researching and visiting.

VR interactive experience - VR technology has been used in the three-dimensional digital city and space-ground integration real-time system.

The notice of holding SDI Development Contest was issued on July 11, which was sent to relevant universities to push it by WeChat public platform. The timeline was:

2 August 2017 - the list of participants was collected. There were 37 groups composed of 56 participants who are undergraduates and postgraduates from different universities, and modeling enthusiasts from different units.

8 August - participants were invited to our institute to be trained in standardized modeling. Technicians made a presentation on texture modeling, model naming and detail processing in the modeling as well as explained and demonstrated the open data and platform interface. Participants were led to visit the unit base and office environment after the training.

17 September - participants were contacted by email and telephone to be informed that modeling results should be submitted in time. All of the submitted modeling results were sorted out.

A total of 35 modeling works have been received as of the deadline for the submission of modeling results. With various production methods and exquisite appearance, the subjects of these modeling works are rich and colorful, embracing ancient and modern building modeling, road and bridge modeling, Buddha and other sculptures modeling, character modeling, live-action modeling and so on.
