Mapping (Cartographic) 'Consulting'

Excerpt of Venezuelan Map Project



"Danesh, I would like to get your tips on cartographic aspects of map of my work" (rephrased). This opportunity is one thing I can't pass. However, it is not easy as you and I would think. This post will be focusing my recent experiences in terms of cartographic consulting.

If you have seen in my previous posts (3D visualization for housing, Mauritian map project and Coordinate capture), the 'clients' had minimal idea of principles of cartography and GIS. The recipients would have no clue on GIS software and very much depended on me to produce the desired outcome. In short, my expertise is meant to deliver a product

Things are bit different with experiences in August and September. In August, I attended the International Map Industry Association (IMIA) Conference in Melbourne and attended Map Hack Day. Please refer to the post for details. In the process of making an online map, my team was divided into two : One group to focus on attributes data and number crunching and another focuses on spatial data preparation. Although it was not consulting, I had a unique experience of educating my ex-employer on how to use QGIS for preparing the data. I have used QGIS before at work and went for training one day to advance my skills. Though not fully utilized, it became handy as my team member struggled on QGIS. For this case, my team member is well versed with GIS, but not in QGIS. I showed him where to do clipping, how to do selections and other aspects of QGIS. In short, my expertise was to impart my knowledge for product build-up.

September Experience

A week ago, I received an email a friend of mine. He is well versed with GIS technologies and cartographic principles. He needed some views and tips on how to enhance map presentation. For me, this was a challenge as there was expectation (bit high one). I am now being viewed as a person from GIS Industry and has cartographic work experience. I would be advising him on ArcGIS and potentially on advanced QGIS.

The day came where my advice would come into play. He presented his projects, his current map templates and the cartographic styling being used. Turnout out, after 1 1/2 hour discussion with him, I learnt a lot of new things from him (specifically on ArcGIS):
  1. Bookmarks: Which saves one particular view
  2. Convert to Graphics: I can convert a Legend in ArcGIS and break the components as individual pieces
  3. Style Sets: A library of style sets (for symbology purposes) can be crafted and reloaded back into Symbology library
  4. Relative pathnames: If your shapefiles are stored in different places (in same directory I believe), this tool allows quick retrieval of files should they move around
From my side, I showed how dissolve can merge all the divisions of a shapefile into one. However, we encountered some issues when summing up totals (of population of attributes) for the dissolving shapefiles. I showed him that in ArcGIS there are two different tool bars he need to be aware for map production. Data Frame toolbars and Layout Frame toolbars may look the same but difference can be noted. Panning in Data Frame means moving the map while its equivalent in Layout moves the paper behind the map.

As our discussion progressed, the questions I was receiving was pushing the limits of my knowledge. I have been insulated from the tips and tricks that can greatly improving my mapping Production process. I hope to be more exposed to advance cartography through these opportunities.

I would like to thank my readers and my friends for offering me challenging opportunities.

57 Years: Evolution of Atlases in Malaysia

Three Atlases, Three Publishers, Three Time eras


As Malaysia recently celebrated its 57th independence day on 31st August, it is worthwhile assessing how this nation has progressed. Malaya, to be specific, got its independence from Britain in 1957 (Malaysia was formed in 1963) and hence, 57 years of independence is unique in its sense. One of the best ways to see progress and changes is to look at old and new national atlases. For this posting, I will be focusing more on Student Atlases' portrayal of Malaysia and how they have evolved over the decades. I will not comment on the production process of the atlas as the information is hard to sought by.

This study is segmented to the following parts:

Contents


Generally, I have noted the contents of the atlases from 1970s to 1990s have not changed. Most of them open up with principles of mapping (i.e. projection, scale) and proceed to Malaysian and world content. In terms of Malaysian content, it is divided into three groups: Physical Geography maps, Human Geography maps and General Reference Maps. In the General Reference Maps, Malaysian atlases do accommodate inset maps of key cities or economic activity area. These inset boxes focus on land usage and economic hotspots of the state or region. Despite constituting another half of Malaysia, Borneo Territories are not accorded with a large scale map (for general reference category). The thematic maps of atlases are generally without any years attached and if they were, they are outdated as much as 6-10 years (from the latest publication date)

1974, 1983, 1994, 1996 (2007 Edn Atlas)

New names or change of spelling for places have been reflected over the years. For example, 70s atlas used to show Muar as Bandar Maharani (primary name). From 80s onwards, Muar became primary name choice for the town on the map. District names of Sarawak (the largest state) has undergone renaming decades ago. New reservoirs appear in the 1990s maps when none existed in 70s and 80s atlases. Despite the updated height, Malaysian geography text books and atlases still carry the wrong height of Mt Kinabalu(it should be 4095 m instead of 4101 m). Emergence of highways criss-crossing the country began to appear in 1990s atlases. With the opening up of new Kuala Lumpur International Airport (KLIA) in 1998, thematic aviation maps were updated with the new location.

How did these Atlases presented the world?
Malaysian student atlases are published in accordance to the geography syllabus and textbooks. From 1970s to 1990s, the atlases had a major emphasis on Regional South East Asia (on a country-to-country basis), followed with serious coverage of Asia. For the rest of the world, these atlases gave more space for North America and Europe. As most of the atlases has their publishers one way or another related to UK, large scale maps of UK are presented in the atlases. Africa and South America, despite their sizes, are displayed in one page maps. This skews supposed Malaysian world view to Asia, Europe and North America (a bit of Australia)


Colour Scheme


My analysis and observation states that atlases produced prior to 1980s (be it Malaysian or International ones), they have strong colour contrast scheme (refer to image above). Specifically, this is very true for topographic relief. The first thing you will see on topographic maps of Malaysia and World in pre 1980s atlases is topographic relief. In this sense, this colour scheme serves the purpose. However, it makes reading of text on the map very hard. For example, Times Atlas of the World (Mid-Century Edition of 1950s) had significant contrasting colours for relief that readers struggle to deduce thousands names dotting the map. Secondly, maybe due to printer issue or other reasons, I have noticed thematic maps have colours not matching their boundary grouping. For example, if the sea is indicated white and agricultural land is yellow, it is possible to see older atlases that some white exist on the landmass. It is subtle.

From 1980s, with better technologies and other reasons, the strong contrasting colour scheme was phased out and replaced with smooth colour transitions. Colours used for topographic maps or thematic maps for atlases show gradual variation and most importantly, toned down. It still captures people attention to relief but this time, not compromising text legibility. Strong colour schemes are only used for certain cases (i.e. 3D Model - none of the Malaysian Atlases have explored this option).

Current situation of atlases


Unlike the glory days (until 80s or even 90s), number of companies producing atlases have went down in Malaysia. Prior to 90s, it was possible to see different publishers producing their own set Malaysian student atlases. Currently I believe there are two companies who produce Malaysian atlases (specifically for students or reference material)- Oxford Fajar (Oxford University Press division in Malaysia) and World Express Mapping Sdn Bhd (WEMS). Oxford Fajar updated their mid 90s Atlas Moden Malaysia dan Dunia (Modern Atlas of Malaysia and the World) until 2007. However, the update was more like changing the cover (to reflect 50 years of Oxford Fajar in Malaysia). The contents in this 2007 atlas had maps reflecting situation of late 1990s (This is a gap of a decade between the publication year and the contents)

Newer atlas from Oxford - Atlas Explorasi Geografi (Geography Exploration Atlas) released recently is more like a book with some simple maps. These newer atlas has discontinued tradition of Oxford produced maps of Malaysia and World for the past decades. The content is more geared to text and the maps were there to reinforce the geographical understanding. 

WEMS also released Atlas Geografi Dunia (World Geography Atlas) both in Mandarin and Malay. I had short glimpse on the contents of this atlas. Most of it simple topographic maps of Malaysia and World.

Conclusion


In short, Malaysia no longer has good atlases that reflect the identity of the nation. Other countries can serve a good example on continuing the strong tradition of atlases in combination with GIS and web capabilities. In Australia, hardcopy Jacaranda Atlas is updated with GIS and is accompanied with online counterpart. This atlas is standard mainstay for all geography students in Australia. Likewise, Oxford produces its Australian atlases and has similar content to Jacaranda. Malaysia no longer has any of this.

The best way forward is the existing publishing groups in Malaysia recapture the older atlas style, combined with GIS enabled updates and have online counterpart. These atlases are very dynamic, interactive and bound to make students get excited in geography.
