Professional Profile


Wijnand Durk Langeraar (‘Wine’) specializes in mapping and modeling with GIS, GPS, remote sensing, and spatial analysis, and is dedicated to implementing this to a wide range of clients and disciplines ranging from urban planning and mapping, to land cover and infrastructure satellite image interpretation and mapping, to modeling of renewable energy scenarios, to land and land use policy and management, to 3D terrain modeling, to GPS-GIS integration, to census mapping and management, to health database development, to disaster management, to environmental and resource modeling, and more.

Recently, Wine has developed a methodology to quantify detailed precipitation during the last 20 years for areas anywhere in the world. Annual, monthly, daily, down to half-hourly rainfall episodes are assessed with a ground resolution of one-tenth of a degree. He is doing this by accessing data derived from NASA’s remarkable Global Precipitation Measurement (GPM) mission. GPM produces worldwide precipitation assessments. By combining maximum rainfall with catchment areas, potential maximum stream flow events can be calculated for road crossings, necessary for robust culvert and bridge designs.

As census mapping manager in Timor-Leste he pioneered and implemented a technique of putting all of the country’s households on the map with GPS during the 2004 Population and Household Census, and subsequently linking the census database with the household locations. This turned out to be a triumph, and a first world-wide (he was interviewed by CNN as a result). It provided the Government with powerful tools for development. Patterns emerge otherwise never noticed, and correlations and causalities become apparent and can be acted upon with surgical precision, thus saving the Government time and lots of money. A number of countries in Africa, Middle East, South East Asia and Pacific have subsequently asked Wine to implement his GPS for Census technique.

He is interested in designing and conducting random sampling surveys applying GIS, satellite remote sensing, and GPS techniques. This bundle of technologies can be utilized not only for rapid appraisals (Forestry, land use etc) but also for sample surveys that must be independent, such as census post-enumeration surveys to quantify omissions and erroneous enumerations, and Living Standards Measurement Studies (LSMS). End 2013 Wine, with Juan Muñoz of Sistemas Integrales in Chile, formulated a revolutionary GIS-based random sampling method for household surveys which is census-independent and politically neutral. This study was sponsored by The World Bank.

Wine's Techniques

Early 2013, Wine developed a novel technique of putting together downloaded Google Earth imagery into seamless and precision geo-referenced mosaics that can be used in a GIS straight away. High-resolution imagery is expensive, and this technique provides a low-cost and very effective alternative.

In 2010 Wine developed a spectacular moving map display technique in the course of a TA project for the Asian Development Bank related to renewable energy in Central Asian countries. These 4-D animated maps show the spatial extent evolution of Net Present Value scenarios for solar and wind power plants with varying electricity tariffs. An enormous amount of information is compressed in these moving map displays. The information is allowing the Bank to make exceedingly informed decisions on exactly where to invest in renewable energy power plants.

In early 2019 Wine has advised the rehabilitation of the Highlands Highway in Papua New Guinea. He analysed catchments upstream of points where highway crosses streams and rivers, and performed average monthly stream flow calculations, and produced maps of population density and distribution, yr 2022 population prognosis, elevation, slope, land cover/land use, earth sciences, and generated other spatial information relevant to road design and rehabilitation..

Apart from the technical aspects of his work, Wine has also provided ample strategic advice to a number of countries. In East Timor and Myanmar he formulated a national spatial data infrastructure. In Mongolia, Iraqi Kurdistan, East Timor, Fiji among other, he formulated strategies for line agencies on how to meaningfully incorporate ICT in their work process. Recently, while working at ADB HQ in Manila he made suggestions on how ADB could integrate ICT and other technologies in its operations and for the development of its client member countries.

At present Wine is involved as geospatial data leader in a project dealing with reducing deforestation through improved spatial planning in the two Papua provinces of Indonesia.

Wine has almost four decades of professional experience in SE Asia, Middle East, Pacific, Central Asia, Europe, and Africa. He is fluent in a good number of languages.

A census-independent sampling strategy for a household survey in Myanmar

In the last months of 2013, Juan Muñoz of Sistemas Integrales in Chile, and I have jointly formulated a novel and very effective technique for random household sampling based for a major part on LandScan population data. Here is the link to LandScan:

The study has been possible thanks to financial assistance from the Development Research Group of The World Bank.

Why did Juan and I feel that a new sampling method was urgently needed? The old way of random sampling is critically dependent on reliable and accessible census databases and census cartography. National statistical agencies are the sole source of such data in many countries, which can make the data hard to get hold of. Even when available, census databases are often unreliable and almost always outdated.

In the report we propose an alternative strategy, intended to delivering a sample of households with well-defined probabilities, on the basis of Geographic Information System (GIS) techniques, Global Positioning System (GPS) technology, high-resolution satellite imagery (Google Earth Pro), and additional information sources other than censuses, in particular the LandScan population database. This method of sampling is politically neutral

The developed technique was formulated using Myanmar LandScan population data, but the technique can be employed anywhere, as an independent low-cost, swift and very accurate household sampling strategy: an eminently suitable alternative way to draw a sample if census results are not available in time.

The reason the technique was developed for Myanmar was because there was an initial plan to implement it there early 2014. This has now been postponed until later this year.
