4. Background
● Data has become the main output of a research.
● But yet it hasn’t been carefully stored, curated, and
opened for further analysis.
● This project presents an alternative approach (considered
to be new approach) for research data management
(RDM), especially in hydrogeological data in city-wide
scope, to support open government data movement.
4

5. Open principles
● Groundwater data should be open and free to use,
● Groundwater data should be in machine-friendly formats and ready for
further analysis,
● Groundwater data should be presented in spatial manner using cheap or
open source resources to minimize the usage of government’s fund.
5

6. Materials (all free and open source)
● Open Street Map (OSM) for base map,
● QGIS desktop dan QGIS cloud for map setup and online hosting,
● Web browsers for exploring information provided,
● LibreOffice or OpenOffice for raw data formatting and manipulation,
● Medium spec computing resources: i3 and i5 laptops,
● Free and open file formats: csv (comma separated values).
6

7. Methods
● Data collection and curation,
● Data survey to test the validity of well point coordinate,
● Valid data preparation and manipulation,
● Data plotting and map hosting,
● As additional activity, we wrote and spread a questionnaire for earth science
students about their knowledge and user experience using proprietary and
open source GIS application.

8. RESULTS

9. Current status
● Groundwater research data are stored in documents as printed materials
and/or in soft file in non machine-friendly formats (eg: pdf, xls).
● Although computer files are available, but it’s stored offline in a closed
system. It’s not accessible for public (with a certain restriction).
● Groundwater data are presented in non spatial manner.
● Groundwater data are now in quasi-invisible status. It’s there but never to
be found.
● Therefore data can’t be furthered analysed given the fact that:
● It’s expensive to get using tax-payer money,
● It’s collected in timely project (mostly 8-10 months),
● It’s collected by a huge man power.

10. Data assessment
We did the following tasks:
● managed to find 250 groundwater well data points for shallow
(unconfined aquifer) with +/- 15 parameters,
● plotted 200 points on to OSM base map,
● clarified 50 points in random sampling to test the coordinate validity,
● re-plotted the clarified points,
● concluded that data curation status is minimum, therefore we set this
project to manage a low level data hosting and visualizations.
10

11. Omitted data
We omitted the following data:
● With mailing address but no coordinate, that we can’t clarify the coordinates.
● Well owned by private premises that refuse to participate in the field survey.
● Groundwater well with no piezometer hole for water measurements.

12. Desktop GIS app and cloud hosting selection
● Sistem QGIS desktop and cloud were selected based on simple survey (using
Google Forms) to 100 students (S1/S2/S3) about their knowledge, skill, and
their willingness to learn open source GIS apps.
● Majority of the students (97%) choose QGIS than GrassGIS after reviewing
the openness, interface and implementation.
● 70% of the respondent claim to have intermediate skill to use QGIS. They
have willingness to migrate to open source app, but claim the strong
attachment to the proprietary app they are using now, due to non conducive
environment.

13. Web-GIS
● System the use web technologies
● Data handling, recovery, management, analysis
● Server -- Client (web-browser or desktop app)

16. Desktop GIS app and cloud hosting selection
● QGIS has 1 GB cloud storage to publish map.
● QGIS has huge collection of add ons and strong user community.
● Less programming skill is needed in using QGIS.

19. Closing remarks
● We have tested the application and workflow to five (5) data staff working for
The Bandung Board of Environmental Management (BPLH).
● They claimed that the methods are easy to use.
● However, they worried about:
○ the willingness of superior staffs (old staffs) to learn about the system,
○ they currently don’t have open data regulation,
○ They currently don’t have any web server infrastructure.

20. Closing remarks
● Groundwater data should be open and accessible for further analysis and
decision making, eg: land use planning, trade permit, building permit.
● QGIS and QGIS cloud can be used as the simplest solution to store and
visualise groundwater data. It needs a
● Future development: this system should be developed with more webGIS
programming, using proposed BoundlessGeo GIS bundle.
