The Tough Road from 2D Maps to 3D City Models

The Tough Road from 2D Maps to 3D City Models | Everything is related to everything else | Scoop.it
The demand for mapping intensively used parts of the Earth, including roads and cities, is steadily growing. This is because today’s rate of urbanisation requires detailed and up-to-date geodata in its full three dimensions. Such datasets help city managers to prevent a decline in liveability, to limit water, air and noise pollution, and to improve fair taxation and rapid emergency response. Crucial is the abstraction of the 3D real world, a concept known as level of detail (LoD). Since 2012 Dr Filip Biljecki has been investigating how to improve the level of detail (LoD) in 3D city models. For his efforts – which were published in a hefty book called 'Level of detail in 3D city models' – he recently received a PhD degree from Delft University of Technology. In acknowledgement of the high standard of his research, he graduated with the rarely awarded cum laude distinction, providing 'GIM International' with reason enough to interview him.

The Mobility Space Report: How much space do car parks take up in our cities? - Geoawesomeness

The Mobility Space Report: How much space do car parks take up in our cities? - Geoawesomeness | Everything is related to everything else | Scoop.it
How much space do car parks occupy in our cities? A quick Google search for the question returns 27 million results, and if you were to scroll through the first page, you get the impression that our cities have way too much parking spaces than necessary. But what does the view from the sky tell us? How much space do they actually occupy?

The Mobility Space Report 

Moovel Lab‘s latest project “What the Street?!” provides a fascinating insight into how urban space is allocated in different cities across the world including Berlin, New York City, Tokyo and Stuttgart (where they have their office) among others.

The concept of “arrogance of space” and how unequally (road) space is being divided in favor of cars isn’t new. What’s interesting is the algorithmic approach that Moovel Labs has taken to highlight the disparity between the different modes of transportation in our cities.

Measuring Vegetation from Satellite Imagery with NDVI ~ GIS Lounge

Measuring Vegetation from Satellite Imagery with NDVI ~ GIS Lounge | Everything is related to everything else | Scoop.it
The measurement of vegetation signatures using remote sensing sources has become a critical way to measure the effects of regional and global-scale drought and agricultural production. It is also useful in distinguishing vegetation in regions, including wild and cultivated varieties. The most common method for this is the normalized difference vegetation index (NDVI) technique.

What is Normalized Difference Vegetation Index (NDVI)?

The concept of normalized difference vegetation index (NDVI) lies with the fact that plants have evolved to reflect near-infrared light, where visible light is strongly absorbed by almost all plants in photosynthesis. The measure is thus an index of these two aspects, helping to show how vigorous plant growth is happening in regions.

Mapping Time: A Detailed Look at Minard's Flow Map ~ GIS Lounge

Mapping Time: A Detailed Look at Minard's Flow Map ~ GIS Lounge | Everything is related to everything else | Scoop.it
One of the most famous maps incorporating time was created in 1861 by Charles Minard, a French Engineer.  The map and chart, entitled, “Carte figurative des pertes successives en hommes de l’Armée Française dans la campagne de Russie 1812-1813″, brilliantly illustrated the march to and from the Polish-Russian border to Moscow by Napoleon’s army and was profiled in the article, Spatial Unmapped on GIS Lounge.

422,000 soldiers began the journey in June of 1812 towards Moscow and only 10,000 made it back to the border after the failed invasion.  Minard’s map has been acclaimed by many for its clear use of geography and time to show how devastating the invasion of Russia by France was on the troops.

Structure in your data can undermine your model validations: the problem and some solutions | Ecography

Structure in your data can undermine your model validations: the problem and some solutions | Ecography | Everything is related to everything else | Scoop.it
Statistical models in ecology are used not just to describe the present state of natural systems, but also to predict their change or development over time. Such models are fairly simple to create and have thus become ubiquitous in all areas of ecological research. To determine whether these statistical simplifications of ecological systems are useful, we need effective model validation procedures that produce reliable error estimates. Unfortunately, many popular evaluation and cross-validation approaches may result in erroneous and misleading assessments of model performance. We need to do better!

Mapping Soil Moisture in Ethiopia Using Remote Sensing Techniques ~ GIS Lounge

Mapping Soil Moisture in Ethiopia Using Remote Sensing Techniques ~ GIS Lounge | Everything is related to everything else | Scoop.it
Ethiopia was once a fertile breadbasket, able to sustain life and produce many different agricultural products in addition to supporting plant and animal life. Over time Ethiopia and the region around it has become less fertile as the population has boomed and water has become more and more scarce.

Ethiopia experienced its worst drought in decades in 2015. The drought has continued into 2016, as April has been dryer than usual in most of the nation. Researchers are using satellite data in order to determine what part of the country is at the most risk, and where water may still be found. Inadequate rainfall has already affected Ethiopia’s crop production which runs in part because of a March-May rainy season.

Isodistance and Isochrone Maps ~ GIS Lounge

Isodistance and Isochrone Maps ~ GIS Lounge | Everything is related to everything else | Scoop.it
When traveling across a landscape, the shortest point from A to B is rarely “as the crow flies” due to barriers or twists and turns in the route.  Likewise, the uniform distance or travel time from a particular point (say five miles from Point A in any direction) can rarely be measure by a circular buffer zone. Instead, isodistance and isochrone calculations are used to show bands of equal distances and travel times from a specific point respectively (typically represented as polygons although the calculations are actually performed along routes, i.e. lines.  In these maps, the outer edges of each polygon represents the isoline).

GIS and Stratified Heterogeneity ~ GIS Lounge

GIS and Stratified Heterogeneity ~ GIS Lounge | Everything is related to everything else | Scoop.it
A method to measure uneven distribution of landscape or population features in a given space is stratified heterogeneity. The method allows one to determine how different given regions or spaces are, allowing the method to determine how patchy or heterogeneous a single strata or different layers are. Variations in a given location within a layer or a group are defined as local heterogeneity, while variations between layers or groups is spatial stratified heterogeneity. The approach is commonly used to determine species, biological, and land cover variations.[1]
