The growth of QGIS at the Federal Department of Town and Country Planning, Peninsular Malaysia

Introduction

The Federal Department of Town and Country Planning, Peninsular Malaysia (JPBD) is a federal agency that advises matters on town and country planning. The scope of administration for the department however is limited to Peninsular Malaysia as Sabah and Sarawak in East Malaysia have their respective town planning agencies. Town and country planning is on the concurrent list in the Federal Legislation, thus, at the federal level, JPBD advises the Housing and Local Government Minister from which JPBD gets its patronage as well as to advise the National Physical Planning Council chaired by the Prime Minister. At the state level, the state director advises the State Planning Committee chaired by the Chief Minister. At the local level, JPBD advises local planning authorities on planning matters by being involved in the preparation of mandatory development plans. At Headquarters, the National Physical Plan Division prepares the National Physical Plan while four regional project offices assist in the preparation of State Structure Plans, District Local Plans and Special Area Plans. As public agencies were traditionally established base on their specialization, JPBD is the custodian of landuse information.


The Project

Quantum GIS (QGIS) was first introduced to the Malaysian Open Source community as a viable alternative to proprietary GIS for public agencies by JPBD at the Malaysian Government Open Source Conference (MyGOSSCON) in 2009 and to the Malaysian GIS community at the 4th National GIS Conference and Exhibition (NGIS) in 2010. JPBD has traditionally been a user of proprietary GIS thus the introduction of QGIS was a real eye opener not only from the point-of-view of Open Source Software (OSS), what more, OSS GIS. Open source philosophy was different thus QGIS felt alien, unsure and unsafe, not surprisingly the idea to use QGIS did not receive much support internally, in fact, it faced resistance in 2010 from the top managment all the way down to the support group.

On the opposite side, request for technical talks on QGIS came from other technical agencies which JPBD gave to the Ministry of Works and the Department of Irrigation and Drainage. Other works to promote QGIS from JPBD came in the form of newsletter articles on QGIS to the Open Source Competency Centre (OSCC) at the Prime Minister's Department and articles introducing QGIS to the Survey Department's GIS Bulletin and the Ministry of Natural Resource's Public Sector GeoSpatial Bulletin. In the meantime, JPBD researched on developing a slope analysis module for QGIS's Windows and Ubuntu version.

The study highlighted pros and cons of customizing a module and the high level of commitment from the management needed to ensure its continual success and adoption. In 2011, JPBD began to further research on QGIS more as an analytical tool rather than a mapping tool in order to pioneer untapped modules or new approaches at exploiting QGIS.

The department eventually promoted the QGIS-GRASS package instead of merely QGIS as it was found to be most powerful and helpful for town planning purposes such as cleaning topology error and overcoming limitations of the default standard inputs. That was merely the beginning.

In order to centralize and share findings in the use of QGIS for town planning purpose which could also be use in other fields dealing with spatial analysis, an unofficial blog established by the author called “QGIS MALAYSIA” at http://www.qgismalaysia.blogspot.com was made to generate a QGIS community in Malaysia. External agencies seem to have more interest in QGIS than JPBD itself and upon their request, JPBD gave QGIS training to the Fire and Safety Department as well as to the Ministry of Education whom later was convinced QGIS will be their de facto GIS tool.

Hearing this, JPBD's Research and Development Division took the initiative and requested for QGIS training and subsequently 12 persons were trained. Word of mouth (a godsend thing, though at times, extremely detrimental) spread that QGIS was indeed user-friendly, easy to use and at par with proprietary GIS in mapping task and could take on proprietary GIS when optimized with GRASS modules.

 

Interest in QGIS stirred and in 2012, with the support of all project office directors, an all-out effort was undertaken by the National Landuse Information Division that spearheaded QGIS to train the 4 project offices as they hold the greatest number of GIS users. By the end of 2012, it is anticipated that at least 320 staff throughout JPBD will use QGIS which accounts for approximately 90 % of GIS users in the department.

That is not all. States town planning departments have also requested QGIS training such as Perak including strong interest from poorer states like Perlis and Kelantan. If this catches on, it is anticipated that the use of QGIS may dominate states planning departments and even extend to local planning authorities, many of which are not wealthy. In the meantime, JPBD is seriously studying the use of the QGIS-PosgreSQL-PostGIS package for every planning office's client GIS-geodatabase server structure to serve as the foundation of JPBD's integrated landuse (iPLAN) network.

Outcome from using QGIS

  1. On the assumption of RM10,000 per proprietary GIS licence, the use of 320 QGIS installations will help save the federal government RM3,200,000;
  2. A total eradication of pirate GIS and increasing trust and confidence in the use of OSS in general and specifically OSS GIS;
  3. QGIS training has been simplier to manage. This means cross-learning between staff, divisions, public agencies and even local planning authorities that use QGIS can be more effective because the GIS used is uniform;
  4. The use of QGIS helps towards synergy with a PostgreSQL-PostGIS geodatabase which the department is planning to use as the foundation of landuse geodatabase throughout Peninsular Malaysia.
  5. It has been faster to process data verification and clean toplogy error.
  6. Users become more courageous and begin to venture into Google Maps and other Internet sources for secondary information;
  7. QGIS being user-friendly encourages users to be more adventureous and explore the many plugins available to their advantage and make their task easier.
  8. GIS a complex tool becomes a friend rather than a hinderance.

Using QGIS for wildlife training in Tanzania

Introduction

Working in southern Tanzania, the Udzungwa Elephant Project (UEP) is using Quantum GIS for its training in wildlife research and conservation. In February 2012, it held a two-day workshop for the Ecology and Protection (anti-poaching) staff of the Udzungwa Mountains National Park, along with members of the Udzungwa Ecological Monitoring Centre.

About the Training

Trainees used their own laptops and were provided with the installer for QGIS 1.7.3 along with key data layers covering the National Park: protected area boundaries, scanned topographic maps, a DEM, roads, ranger posts, and habitat types.

By the end of the two days, everyone was able to add GPS download data, create and edit new layers, save map projects, design print composers, and save graphics files for inclusion in reports and presentations - this last feature is specially useful in using GIS to help in normal workflows. Even during the course, National Park staff were using the GIS to view the GPS locations of new-reported elephant carcass locations - the result of poaching - and to start planning responses.

QGIS offered us several attractions: not only is it completely free, but its open source nature makes it responsive to particular development needs; it runs well on older computers and has a relatively small installer; and in general we have found it user-friendly for newcomers to GIS.

The Udzungwa Elephant Project is based next to Tanzania's Udzungwa Mountains National Park, a range of evergreen forested mountains reaching over 2,500 metres. It studies the ecology of elephants in and around the mountains, with the aim of understanding how elephants move between different Tanzanian parks and reserves, and how such corridors might be maintained while reducing crop damage caused by elephants. More widely, elephants are a "flagship species" for the conservation of the incredible wildlife and landscapes of southern Tanzania.

Working with QGIS in a spatial data infrastructure of Jalisco in Mexico

The Instituto de Información Territorial del Estado de Jalisco is a government organization which was founded in 1998 to share geographical information between the government agencies of Jalisco in México.

 

SITEL

Figure 1: "Exploring the data with its online viewer.

Within the years, the institution has gathered loads of information in several formats such as SHP, DWG, DXF, GeoTIFF and ECW, among others. So, what we wanted was to have all this information available, organized and in a common format with the purpose of being able to provide and display it over the Internet.

SITEL

Figure 2: Connecting to the Spatial Data Infrastructure with WMS

That's how it was developed the Sistema de Información Territorial Estatal en Línea, with the main target to build a spatial data infrastructure which allows our government agencies to share this kind of information to be included in their own projects as health, security or mobility.

 

Decision for QGIS


I decided to use Mapserver and PostgreSQL with PostGIS extension to be able to deliver our satellite imagery, orthopothos, digital elevation models and vector information with Web Map Services, thinking that any application will consume our services. But the problem was that many of the commercial and free applications don’t work with OGC standards, specially with WFS. After exploring many geographic information systems, I realized that QGIS was the only one which
can connect to WMS, WCS and WFS successfully.

What we use QGIS for

Internally, we use QGIS to check the raster and vector data of the agencies before publishing it, and after its integration, we used it again to test the Web services that we’ve created. Also, we have done many spatial analysis with QGIS pulling the data directly from our PostgreSQL spatial database, then, we export the results as shape files.

SITEL2

Figure 3: Connecting to the Spatial Data Infrastructure with WFS


We’re encouraging our users to download QGIS and link directly with our Sistema de Información Territorial Estatal en Línea, mainly because it fully supports OGC standards and has many interesting features like geoprocessing tools, which allow them to make analysis of their interest, and all this absolutely for free.

 

Conclusion


This project understood as the technological component of a Spatial Data Infrastructure, has been considered as a PostGIS case study, and I have to say that working with open source in all of our system’s cycle, has been satisfactory and trustworthy, the best choice that we have found to share our geographic information.

Using a free GIS at Jaime Moniz Secondary School: Quantum GIS

There will be democratic teaching in our schools or education communities when we generalize the use of Open Source software. This demands not only a change in people's way of thinking (sometimes molded by advertising), but also a sustainable management of expenses and, indirectly, fighting against software piracy. These advantages which are inherent to the philosophy of the Open Source software will be the model to follow if we want a quality education without boundaries or dependencies of any kind. From this perspective, class 35 of the 12th grade belonging to the technological course of territory and environment at Jaime Moniz Secondary School, uses QGIS to develop activities proposed in Geographical Information Systems, Applied Information Systems and during their training period. Within the range of options of free GIS, there were three underlying reasons for the choice of Open Source selection: the user friendly and intuitive approach, supported by online information provided by forums; the several software plug-ins and the quality of the product in its final stage. (One should bear in mind that these academic works were done by students who belong to a very young age group.)

The Project - Expectation

Expectation was the most dominating feeling in the firth lessons! The group of students had only a theoretical and somewhat vague knowledge about the issue of GIS. It was, therefore, necessary to link practical activities to that theoretical knowledge - at first, through the gathering of geographical information by using a support map, within the school's perimeter, and later, by using a GPS, concerning the area surrounding the school. In figures 1 and 2 it is possible to view some of the activities developed in class.

Figure 1: "Distribution of dustbins (green) and garden benches (yellow) at Jaime Moniz Secondary School"

At present, some students are still using the QGIS to make different work plans during their training period. In figure 3, a student's work stands out: it is related to the distribution regarding the number of the inhabitants of Santo António, including a placement proposal for recycle containers, in a parish of Funchal.

Figure 2: Functional map of an area in the old part of the town of Funchal, surrounding Jaime Moniz Secondary School

Decision for QGIS

Number of the inhabitants (example) Generally speaking, QGIS allured the students: “to accomplish basic functions of GIS through exercise associations of graphic and non-graphic elements”; “to upload alphanumeric data”; “use functions of spacial analysis”; “to make thematic maps”; “to make a Digital Elevation Model” and, last but not least, “to recognize the relevance of a free GIS for the analysis of geographical  information, as well for the sustainable management of the territory”. These theoretical and practical purposes are achieved together along with other goals, extremely important in the education context, such as: “creating a diversified educational experience”; “being in contact with local reality” and “developing a constructive, positive and critical mind”.

From the class room to the education community

The idea of creating a website: http:// www.sig-na-jaime-moniz.webnode.pt implied two main purposes: “spreading the word about project works done by the students” and, simultaneously, “show the importance of Open Source QGIS for the accomplishment of these school works”. At present, the website is a motivation source for the follow up of the whole
teaching process.

Figure 3: Placement proposal for recycle containers in the parish of Santo António

Conclusion

In a flashback analysis of the whole process, I feel that the idea of using QGIS, as a tool, to accomplish some teaching purposes, was an excellent choice. At first, its use involved a lot of expectation. I had never used GIS before and, therefore, I was learning and teaching at the same time. The fact that the GIS turned out to be extremely user friendly together, with the information available online, was a blessing for me. Moreover, the school did not have to pay for another software license nor it was dependent on license renewals, which substantially improved the teaching quality, without any extra expenses. At present, students use QGIS almost on their own to accomplish their different work plans. I hope the final result shows the amount of effort involved in the whole learning process.
