Content Introduction Examples from literature Student’s experience
Outline Spatial Data Infrastructure User Application
Research on SDI use Systematic research is limited Main focus was on the development Study of the SDI phenomena Challenge for the future
Example: noise mapping
Implementation
Example: Land administration
Example: Vietnam

Flooding Rockhampton Source: Scholte-Albers, 2013
Special portal Source: Scholte-Albers, 2013
Conclusion It is possible and a special portal (application) based on SDI is created. Source: Scholte-Albers, 2013
Student’s example: Travel Can Travel Information Be Found in USA, Canada, and New Zealand National Geoportals? Source: Xiaxia Gao, 2013
Requirements 5 Important KindsExplanationsSearch Terms Travel DestinationsWhere 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)” WeatherWeather and temperature affect travels. They play important roles in travel information. “Weather” “Temperature” AccommodationsPeople 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 WarningsTravel warnings are new information compared to other kinds, but they are absolutely necessary. “Travel Warnings” TransportationTransportation 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)” Source: Xiaxia Gao, 2013

Conclusion It is partly possible to use the SDI’s for travel support, but information is not presented in a user friendly way. Source: Xiaxia Gao, 2013
Student’s example: Hydrological modelling Downloading geographical data for a hydrological model with Spatial Data Infrastructures DINOloket and Nationaal georegister. Objective: hydrological modelling program duflow Source: Karen Vonk, 2012
Example Data (groundwater wells) Source: Karen Vonk, 2012
Soil Source: Karen Vonk, 2012
Conclusion 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” Source: Karen Vonk, 2012
Student’s example: Hazard assessment Hazard Assessment using Open Source Data: A case study for chittagong, Bangladesh Source: Mohammad Abdul Aziz Patwary, 2013
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 influence 3 - Over 93% of the catchment areas of the major rivers flowing through Bangladesh lie outside the country 4 3 Ali, Ahmad and Ahmed, 2003 After Mirza (2002)
Approach Source: Mohammad Abdul Aziz Patwary, 2013
Data Requirements Source: Mohammad Abdul Aziz Patwary, 2013
Results for Landslide Source: Mohammad Abdul Aziz Patwary, 2013
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. Presentation style is free
