Conclusion

It is possible and a special portal (application) based on SDI is created.

Student’s example: Travel

Can Travel Information Be Found in USA, Canada, and New Zealand National Geoportals?

Source: Xiaxia Gao, 2013

Requirements5 Important Kinds Explanations Search Terms

Travel Destinations Where to go is always the first thing people think about for travel. Because different kinds of travellers prefer different destinations, only generalized words “Tourist Information” and characteristic kinds “National Park(s)” and “Museum(s)” are selected as search terms.

“Tourist Information”“National Park(s)”“Museum(s)” 

Weather Weather and temperature affect travels. They play important roles in travel information.

“Weather”“Temperature”

Accommodations People need places to stay during travel. Accommodations are essential things to be considered. Here “hotels” is picked out as a typical kind of accommodations information.

“Hotel(s)”

Travel Warnings Travel warnings are new information compared to other kinds, but they are absolutely necessary.

“Travel Warnings”

Transportation Transportation information is always searched. And there are various transportation systems in different countries. Here only three search terms are listed representing general means of travel.

“Airport(s)”“Highway(s)”“Train Station(s)”

Conclusion

It is partly possible to use the SDI’s for travel support, but information is not presented in a user friendly way.

She was able to locate the necessary data, but

“I was only occasionally able to use web map service and I was never able to download the dataset”

SOME INFORMATION ABOUT BANGLADESH

Hazard Assessment Using Open Source Data: A Case Study for Chittagong, Bangladesh

- About 10% of the country is hardly 1 m above the mean sea level (MSL) and one-third is under tidal influence3

- Over 93% of the catchment areas of the major rivers flowing through Bangladesh lie outside the country4

Results for Landslide

Conclusions Hazard assessment using open source data

is partially possible (national level).

Data for a country like Bangladesh is not yet available as open source for hazard assessment on a district or regional level.

Data sources indicates that almost all the gathered data are from outside the country, mostly from USA

Source: Mohammad Abdul Aziz Patwary, 2013

Conclusions

SDI’s are used, but systematic analysis of its use is limited

The use is mainly indirect (through applications)

The next decade use will drive SDI developments (personal expectation)

Assignment of week 4 Case of the week 4 “The use of your SDI in a context”

In this final presentation imagine that your group as a responsible for SDI for your case study country, have to demonstrate to the ministry on how SDI was used in a specific use scenario. You have to define the use scenario on your own. For example it can be: natural disaster, project on land development, project on improving traffic safety, etc.

In your presentation consider the following questions:

1. What is the use scenario problem? 2. Which information/application is

needed to approach the scenario problem. 3. Which data from your (and other) SDIs

you will use.

Please demonstrate the use of your SDI portal to address the problem.
